Which 16 Gaming Laptops? Legion 5 Pro vs Zephyrus M16




 Which is the better 16” gaming laptop, LenovoLegion 5 Pro, or ASUS Zephyrus M16? I’ve compared both laptops to show you thedifferences and help you decide which is worth it. Both of my laptops have Nvidia RTX 3070 graphics,though the Legion has a higher power limit. They both have 8 core processors, howeverthe M16 is using an Intel i9-11900H while the 5 Pro has the Ryzen 7 5800H, but thereis also an Intel based 5i Pro coming soon. Both have 16 gigs of memory, a 16” 165Hzscreen, a 1TB NVMe M.2 SSD, while the M16 has a larger battery. There are also cheaper lower specced optionsof both laptops, you can find examples as well as updated prices with those links downin the description. The build quality of both feels nice, theM16 has a darker finish and soft touch interior which I personally liked more. The M16 is smaller than the Legion 5 Pro inevery dimension, not too surprising as that’s one of the key features of the Zephyrus series. This also results in the M16 being quite abit lighter compared to the Legion 5 Pro, and this difference increases further withthe power bricks, as Lenovo’s is larger. Both laptops have 16” 165Hz screens witha 16:10 resolution that’s higher than standard 1440p. 








They both have Adaptive Sync, however onlythe Legion 5 Pro has a MUX switch, meaning we can disable the integrated graphics andoptimus with a reboot to boost gaming performance, and the 5 Pro also gives you the option ofG-Sync when in this mode. The color gamut on the M16 was quite a bitbetter, though the Legion 5 Pro isn’t exactly bad or anything, especially as far as gaminglaptops go. I’d say the M16, shown by the red line here,also has a better range of brightness, the Legion 5 pro gets dimmer much sooner and dropsoff quickly after 100%. Yeah the Legion gets slightly brighter at100% brightness, but I think the M16 gives you more control of the brightness at differentlevels. The M16 was slightly ahead when it came toscreen response time, but it’s such a small difference that I’d say this is well withinmargin of error, at least considering in the past I’ve tested three ASUS TUF A15 laptopswith the exact same panel model and I found the response time could vary by up to 3ms. The Legion 5 Pro was a little ahead when itcame to total system latency however, which is the time between mouse click and gunshotfire in CS:GO. This is likely because I’ve found laptopsthat have to send the display output via the integrated graphics first, AKA no MUX switch,generally have more overhead. Regardless, both were lower compared to mostother laptops tested. My M16 had more backlight bleed, however thiswill vary between laptop and screen, and honestly I never noticed this during regular use anyway. Both laptops have a 720p camera above thescreen, but neither have IR for Windows Hello face unlock. The Legion has a switch on the right thatphysically disconnects the camera for privacy. This is what the camera and microphone lookand sound like, and this is what it sounds like while I’m typing on the keyboard. Now here’s the same test over on the M16,the audio is a bit better, though you can judge both for yourself, and here’s whatit sounds like while typing on this one. The keyboard on my 5 Pro just has white backlighting,but there is also a 4 zone RGB option too, while the m16 has an RGB keyboard, but withless customization as it’s a single zone.




 Personally I preferred typing on the Legion5, but the M16 was fine too. The precision touchpad on the M16 seemed abit larger and though both were good, I preferred using that one. Both have power buttons separate from thekeyboard, but the M16’s is also a fingerprint scanner which I found to work fast and accurately. The M16 has two front-facing speakers as wellas subwoofers underneath, while the Legion has its speakers underneath only. The M16 had more bass, but at higher volumesin my opinion it didn’t sound as nice overall compared to the 5 Pro. The I/O layout is quite different, the onlything in common on the left is that both have a USB 3.2 Gen2 Type-C port and 3.5mm audiocombo jack. The M16 otherwise has its power input, HDMI2.0b output, gigabit ethernet, USB 3.2 Gen2 Type-A port and a Thunderbolt 4 port on thisside. Neither have much going on over on the right,presumably to keep cables out of the way of right handed mouse users. They both have a USB 3.2 Gen1 Type-A port,but the 5 Pro has the camera disconnect switch while the M16 has a MicroSD card slot andKensington lock up the back. The rest of the I/O for the Legion is on theback, which I personally prefer as bulky cables run out the back and stay out of the way. From left to right it’s got gigabit ethernet,a second USB 3.2 Gen2 Type-C port, three USB 3.2 Gen1 Type-A ports on the back for 4 intotal, HDMI 2.1 output, and the power input on the far right. I like that the ethernet port on the Zephyrusis the opposite way to the Legion 5 Pro as it lets you pull out the cables without theneed to lift up the laptop. The 5 Pro supports charging over Type-C, butonly with the Type-C port on the back, while the M16 supports this with both Type-C ports. Both of those Type-C ports on the M16 alsooffer DisplayPort 1.4 output, while again only the one on the back of the Legion does,and the front most Type-C port on the M16 can be used to bypass the integrated graphicsand optimus and get a speed boost in games, which I’ll show you a bit later. The 5 Pro has newer HDMI 2.1 while the M16has the older HDMI 2.0b, but that’s only really going to be a limitation if you’rerunning a 4K high refresh screen or something. The M16 has two USB Type-A ports in totalwhile the Legion 5 Pro has 4, but the M16 is Intel based so it also makes use of Thunderbolt4, which isn’t possible with the Ryzen configuration of the Legion 5 Pro, and the Zephyrus alsohas the Micro SD card slot. The Legion was definitely easier to open,the front of the m16 is just all flat with nothing to really grip onto, while the lidof the 5 Pro sticks out a bit.




 The lid of the M16 has a sort of prismaticrainbow finish below the CNC milled holes, which has a subtle shine depending on theangle of light. The 5 pro has the Legion logo in the centerwhich lights up, however you can optionally turn it off with this shortcut. The 5 Pro appears to have more holes for airintake up the back, and we can confirm this by seeing where light shines through the panels. Inside both have the battery down the frontand two M.2 slots for storage above, however the Intel 11th gen platform means one of theM16’s is faster PCIe gen 4. Both have a Wi-Fi 6 card, but the 5 Pro hastwo memory slots while the M16 just has the one. Now the Zephyrus M16 has either 8 or 16 gigsof memory soldered to the motherboard, and this just seems to be something they do withall of the Zephyrus laptops in order to keep it on the thinner side. You can still upgrade the memory, it’s justmore limited as there’s only one SODIMM slot, while the Legion 5 Pro has two SODIMMslots. Realistically, I think if you get the 16 gigoption of M16 and install a 16 gig stick you’ve got 32 gigs in dual channel, which will beplenty for most people when it comes to gaming, at least in my personal opinion considering16 gigs still seems to be a pretty good sweet spot today, but regardless the Legion 5 Prodoes technically support more memory. If you were to max out the M16 best case youcould go up to 48 gigs, while the Legion 5 Pro should be able to take up to 64, and ifyou were running different memory sizes on the M16 to achieve that you’d face issuesdue to asynchronous dual channel - a topic that I’ll cover in another video soon. Now all that said, there are some memory issueswith the Legion 5 Pro to be aware of. I’ve already covered this in way more depthover in this video over here if you want all the details, but basically the Legion 5 Projust ships with slower memory. It’s an unfortunate side effect of the currentsupply issues, but as I’ll show you later, we can get a fairly significant speed boostin games by upgrading the memory on the 5 Pro. The battery in the Zephyrus M16 is largerat 90Wh compared to the 80Wh in the Legion 5 pro. Despite this though, the Legion 5 pro waslasting quite a bit longer in the YouTube playback test, and 15 minutes longer whilerunning an actual game. The top of the graph is littered with Ryzenbased laptops, so presumably these just do better when it comes to battery life. This is also despite the Zephyrus automaticallyswapping the screen refresh rate down to 60Hz when you unplug from wall power. The Legion 5 Pro doesn’t automatically dothis on its own, however you can press the easy function plus R shortcut key to makeit do the same thing. So even with defaults, the Legion 5 Pro hasan edge run time, but if we instead run the screen at 60Hz, as per the green bar, we canfurther boost it by about 2 hours, making it one of the better results recorded. Let’s check out thermals next. Both laptops have two fans and exhaust airout of both the left and right sides as well as the back, though the M16 appears to havemore heat pipes. The M16 uses liquid metal on the processor,while the 5 Pro has regular thermal paste. The M16 also gives us control over the fans,while the 5 Pro does not. The M16 also has a slight incline when youopen the lid, which helps air get into the fans underneath. Both laptops have different performance profilesin software, however personally I prefer that the Legion makes it visually clear at alltimes what mode you’re running in as the power button changes to reflect this. I’m only going to compare with the highestperformance modes available on each laptop. If you do want to see how both of these laptopsperform with different performance modes then I suggest referring to the full reviews linkeddown below.





 These are the temperatures for both laptops,tested at different times but in the same ambient room temperature. The Legion 5 Pro was significantly coolerinside when just sitting there idle, however the M16 was cooler when running a worst caseCPU plus GPU stress test, or while playing an actual game. These are the clock speeds while gaming orunder stress test. Under stress test the 5 Pro is reaching higherCPU and GPU speeds, however in this particular game the M16 was hitting higher CPU speeds,though the GPU was behind. This is explained by looking at the powerlevels being hit. In the stress test the CPU power levels aresimilar, however the GPU in the Legion 5 Pro is able to use much more power, and more powerequals more performance, but also heat. The difference between the GPUs is even largerin the game, though dynamic boost on the M16 instead seems to boost its processor and lowersthe GPU power. The M16 was doing better in a CPU only workloadlike Cinebench, both in terms of multicore and single core performance. You could argue that we’re comparing ani9 with Ryzen 7 instead of Ryzen 9 here, and yeah that might change things a bit, you canget a rough idea with the other Ryzen results higher up on the graph, such as with the Legion7. The M16 being an Intel based platform hasan ace up its sleeve though, it can be undervolted. The M16 lets us undervolt the processor upto -0.08 volts through the BIOS, and by doing this it’s able to get one of the betterscores out of all laptops tested, even above most of the 5900HX laptops, with the exceptionof the Strix G15 Advantage edition, though it’s very close. The tables turn when running on battery powerthough, generally Ryzen seems to be more efficient when running on battery power, as most ofthe top results are now AMD based. That said, the M16 still has the lead whenit comes to single core performance. The M16 felt quite a bit warmer when bothare just sitting there idle doing nothing, most laptops I test are around 30 degreesCelsius like the Legion. The Legion was still cooler when running stresstests too, the M16 has a hotter spot in the middle though its WASD area is quite coolcomparatively, let’s have a listen to fan noise next. Both were quiet when sitting there idle. When under stress test in the highest performancemode though, the M16 was louder, and it can get further louder if we instead max out thefan, something that’s not an option on the Legion. The M16 was also running cooler, at leastin terms of the internals, so in addition to the lower power limits the increased fanscould be contributing to that. Personally, I see louder fans as an improvementas there’s user control. If you do want them quieter then you can dothat, but if you want them louder at the expense of more noise then you’ve got that optiontoo. Personally I just think user choice is best,and it’s kind of sad that the 5 Pro doesn’t let us control the fans. Now let’s compare both laptops in a fewdifferent games. I’ll be looking at 1080p and 1440p resolutionshere as that’s what I’ve got data for for the purposes of comparing. 16:10 resolutions are still pretty uncommon.



 We’ll start out by looking at results withboth laptops running at stock, but then after that I’ll connect an external screen tosee what sort of a boost this gives the M16 and I’ll also upgrade the memory of the5 Pro to see how that helps. Cyberpunk 2077 was tested in little Chinawith the street kid life path on all laptops. The Legion 5 Pro is reaching around 12% higheraverage FPS when compared to the Zephyrus M16 with the same, but lower powered RTX 3070graphics. The M16 isn’t the worst 3070 result or anything,it’s actually ahead of the Zephyrus G15 with RTX 3080 here, but the 5 Pro is the bestresult I’ve recorded from a 3070 so far in this game. I’ve got less data at the higher 1440p resolutionas not a whole lot of laptops have these screens yet. Regardless the Legion 5 Pro was also aheadhere too with a slightly lower 11% higher average FPS, but hey again the M16 is stillbeating the similar wattage 3080 in the G15 below it. Red Dead Redemption 2 was tested with thegames benchmark, and the Legion 5 Pro had a much higher 20% boost to average FPS inthis one, though it’s not quite the best 3070 result anymore, being beaten by 5 FPSby the XMG Neo 15, while the M16 is now the lowest 3070 I’ve tested here. The differences are even larger at the higher1440p resolution. The Legion 5 Pro was now hitting 35% higheraverage FPS compared to the M16, and the M16 was about 10% ahead of the regular Legion5 with RTX 3060. Control was tested walking through the samepart of the game on all laptops. This is a GPU heavy test at high settings,even with the lower 1080p resolution, so it’s no surprise that the higher GPU power limitpresent on the Legion 5 Pro puts it ahead of the M16, though at 11% higher it’s notas big of a difference as the last game. The M16 was still close to 60 FPS at 1440p,but the Legion 5 Pro was still doing better here, whether we’re looking at 1% low performanceor average frames per second. If you want to see how well both of theselaptops perform with their native 2560 by 1600 resolution then refer to those videoslinked in the description, as I’ve tested both laptops in plenty more games, and tobe fair this 16:10 resolution is what you’d be likely to actually play with if you wereto buy either of these. Now the Legion 5 Pro has a MUX switch, soit can bypass optimus by itself, but the Zephyrus M16 does not have this, but we can bypassit by connecting an external screen to the front most Type-C port, as that connects directlyto the Nvidia GPU. Shadow of the Tomb Raider was tested withthe games benchmark, and I’ve got the external screen result with the M16 highlighted ingreen, which is around 6% higher than the Legion 5 Pro. This is despite the M16 having a lower powerlimit GPU, so it would appear that the i9 processor may have an edge here over Ryzen. Now hold on just a minute, I mentioned earlierthat it’s possible to boost gaming performance of the 5 Pro by upgrading the memory, so let’sdo that and see how this helps. With better memory, the Legion 5 Pro is backin front of the M16, and the m16 already comes with acceptable memory. This is at the lower 1080p resolution. In general the memory upgrade will matterless at higher resolutions, such as the native 2560 by 1600 that both laptops support, thoughat the same time higher resolutions may also see a larger benefit of the higher GPU powerlimit from the 5 Pro.




 If you plan on using either of these laptopsto play games with an external screen then the M16 can certainly close the gap, but ifyou’re primarily using the laptop screen then the MUX switch in the 5 Pro will giveyou a performance advantage, and as we saw that can be further helped by upgrading thememory. That higher GPU power limit is responsiblefor the Legion 5 Pro doing better in all of the 3DMark tests, as per the purple bars. The 5 Pro was scoring 6% higher in the FireStrike graphics score, 14% higher in the Time Spy graphics score, and 11% higher in thePort Royal ray tracing test. Now let’s check out some content creatorworkloads. Adobe Premiere was tested with the Puget Systemsbenchmark, and I’ve noted in the past that this test seems to benefit greatly from Intel’s11th gen processors, which seems pretty clear given the top three results are all 11th gen,granted only the top two are Tiger Lake, the 11900K is Rocket Lake. In any case the M16 had a massive 25% leadover the 5 pro here. The M16 was also ahead when it came to AdobePhotoshop, however the difference isn’t quite as big as before. Nevertheless, the M16 was reaching a 8% higherscore in this test. The 5 pro was tested with stock memory though,so it may be possible to close the gap with the memory upgrade. DaVinci Resolve typically depends more onthe GPU, however the M16 was still slightly ahead of the 5 Pro, so it would appear thatthe processor difference is offering a benefit too, which probably also explains why thesame CPU in the Zephyrus S17 was the best score at the top. SPECviewperf definitely depends more on theGPU, so it’s no surprise to see the 5 Pro in the purple bars ahead in all but the 3DStudio Max test. Both laptops had a 1TB NVMe M.2 SSD, howeverone of the M16’s slots uses the faster PCIe 4.0, a benefit from Intel’s 11th gen platform,so much faster speeds are possible, as seen by the read speed differences, though thewrites were better with the SSD that came in my 5 pro. The M16 also has a MicroSD card slot, a nicebonus for creators that the 5 Pro doesn’t have. Linux support with an Ubuntu 21 live CD wasbetter on the Legion, because it doesn’t need software to change the performance modesor keyboard lighting effects, as these are baked into firmware you can still change themwithout any software. The same shortcuts on the M16 didn’t workout of the box in Linux.




 I’d say the BIOS on the Legion also hadmore customization, though that said a lot of the changes can also be done through softwaretoo. The ASUS BIOS is pretty standard and the sameas pretty much all their other gaming laptops, though as mentioned there is a section forCPU undervolting. Alright let’s discuss prices next, thiswill change over time so refer to those links down in the description for updates. At the time of recording, I’ve only beenable to find the price for the cheaper RTX 3060 models. The M16 with the same i9 processor but 3060is $1850 USD, while the 5 Pro with Ryzen 7 5800H, RTX 3060 and the same amount of RAMis $100 cheaper. All things considered, I think these are bothpretty great gaming laptops, but personally I’d probably be leaning towards the Legion5 Pro for the MUX switch. At least if the priority is gaming, as wesaw the 5 Pro did do much better there, and it’s also $100 cheaper, but what I wouldpersonally do is I’d take that $100 and I would upgrade the memory of this machine,because as we also saw that could give a pretty significant performance boost, but that’sdefinitely not to say there’s not a place for the M16, so let’s recap the resultsfrom both. The M16 is lighter and not quite as big, butthis is at the expense of lower performance in games due to lower GPU power limit. Personally, I don’t really have too muchissue with a slightly heavier and thicker machine if I get more performance, as longas it’s still somewhat portable and not a full on desktop replacement. That said, depending on the workload, theM16 could do better. Take Cinebench for example, the m16 was doingbetter both in terms of single and multi core performance, plus the Intel platform has theadvantage of undervolting for a further boost. Additionally, the M16 was ahead of the 5 Proin all of the content creator tests, it’s got more brightness control on the screen,it’s got a higher color gamut on the screen, and with that MicroSD card slot I think theM16 would be a better option for someone also doing content creation. The M16 was also generally cooler on the internals,at least when under load and not idle, which is in part probably a side effect of the lowerpower limits required to get this thinner design. In terms of the actual exterior where you’llbe touching and using it though, the M16 was definitely warmer compared to the 5 Pro, andthis was in spite of its louder fan noise, liquid metal application on the processor,and lift up hinge design to get air underneath for cooling. The M16 is also more limited when it comesto memory upgrades, as some is soldered to the board, but for most people playing gamesI don’t think this will be a real issue if you get the 16 gig soldered to the boardoption and install a 16 gig SODIMM stick. The Legion 5 was lasting much longer whenrunning on battery, and this could be boosted by using the shortcut to swap to 60Hz, somethingthe ASUS laptop does automatically, however the Intel platform seems to just burn throughbattery faster. Ultimately, I think both are pretty good gaminglaptops and it’s going to be kind of difficult to go too wrong with either. It depends more on what you plan on doing. If gaming is the priority with the laptopscreen I’d pick the 5 Pro, but if you do what to do some content creation the M16 doeshave some nice extras there. But yeah, at the same time both of them canhandle content creation and gaming just fine, especially with the high end specs I’vegot in these models. It may have been preferable to compare theLegion 7 instead of the 5 Pro, as that would be Ryzen 9 vs Intel i9, but my Legion 7 hadRTX 3080 graphics and I wanted to keep the same GPU for a fair comparison here. I suppose you could argue that the M16 doesn’tgo higher than RTX 3070 graphics, so maybe it’s still useful to compare a top specM16 against a top spec Legion 7? Let me know in the comments if that’s acomparison that you would want to see.
