Comparing The BEST Laptop GPUs! RTX 3080 vs RX 6800M


So who makes the best laptop GPU?Should you get Nvidias RTX 3080 orAMDs RX 6800M? Ive compared both in 18 gamesat 1440p and 1080p resolutions to find out! These are the differences in specs betweenthese two top end laptop GPUs. The RTX 3080can have either more or less GDDR6 memory asits available in 8 or 16 gig options, while the6800M has 12 gigs.

The 6800M has a higher memoryspeed, while the 3080 has more memory bandwidthand a larger memory interface. CUDA cores andstream processors arent directly comparable,so it doesnt mean much that the 3080 has more,though the 3080 has a higher maximum power limit.

To do this testing Im using the Neo15 from XMG in Europe for the RTX 3080,also known as the Mech-15 G3 from Eluktronics inthe US market, and the Strix G15 Advantage Editionfrom ASUS for the RX 6800M. Both laptops have thesame Ryzen 9 5900HX CPU, and both were also testedwith the same kit of memory with an externalscreen attached to bypass the integrated graphics. As far as Im aware, this is the only RX 6800Mlaptop currently available and I believe itsthe full wattage option as AMD lists it as145 plus watts on the spec sheet and I foundit would run at around 145 to 150 watts in a GPUonly stress test.

But specific power levels willof course vary depending on the workload as AMDssmartshift moves power between the CPU and GPU. My RTX 3080 is also full powered with a 150watt power limit, plus an extra 15 watts withNvidias dynamic boost, which works ona similar principle, so up to 165 watts. Along with being full powered, my 3080also has 16 gigs of VRAM rather than 8,so it represents a best possible case. Alright so lets start out by comparing bothlaptops in 18 games at 2 different resolutions,then afterwards well compare things like pricing,cost per frame, content creatorworkloads and power draw.

Lets start out with Far Cry 6, whichwas tested with the games benchmark.

Ive got the 1080p results down thebottom and the 1440p results at the top,with the RTX 3080 results above the RX 6800Mresults. At 1080p the 6800M was reaching an11% higher average frame rate when compared tothe 3080, though this is an AMD sponsored titleso thats not too surprising, and the differencewas far smaller at the higher 1440p resolution.This game launched with AMDs FSR support,and this can be used to boost performancefor both AMD and Nvidia GPUs. With FSR setto quality mode both get a larger boost toperformance at 1440p compared to 1080p, andthis also gave the 6800M more of a lead. As Far Cry 6 is an AMD sponsored title,to keep things balanced lets do Controlnext as an Nvidia sponsored title.

At 1080p the3080 was reaching an 8% higher average frame rate,however there was a larger 21% boost seenin the 1% low, so less dips in performanceon the 3080. This game has DLSS support, andunlike FSR this is only available for Nvidiagraphics. The performance boost on offer is kindof crazy, at 1080p the 3080 is now reaching a 60%higher average frame rate, compared to the 8%we saw before turning on this single setting.Even the 1% lows from the 3080 are ahead ofthe average frame rates coming from the 6800M.This game supports ray tracing, and while I couldhave also combined DLSS on the 3080 to boost iteven further, I just wanted to compare pure RTperformance here.

At 1080p the 3080 was reachinga 32% higher average frame rate, so much betterthan AMD in terms of ray tracing performance. Cyberpunk 2077 was like three frames higher on the3080 laptop on average, however interestingly the6800M was reaching a higher 1% low at the lower1080p resolution. This wasnt the case at 1440p,but both are quite close together therenow. This is another game with DLSS support,so its possible for the 3080 laptop to seesome big gains. At 1080p now the 1% lows areabout the same, but the 3080 was now reaching a32% higher average frame rate in the same test.

Even the 3080s 1% low at 1440p was ahead ofthe 6800Ms average frame rate with DLSS in use. Red Dead Redemption 2 was testedwith the games benchmark,and the 6800M was in the lead here, thoughas we saw in my recent 3070 vs 3080 video,for some reason the 3080 was actually alittle behind the 3070 in this game at 1080p,so other 3080s may close the gap.

Anyway itsnot as if the 3080 is unusable or anything, near80 FPS at high settings 1440p is still a greatresult. This game also has DLSS support, thoughwith quality mode enabled its not boosting theframe rates as much as in previous games, so the6800M still maintains a reasonable lead even withthe 3080 taking advantage of this speed boost. Microsoft Flight Simulator was tested in theSydney landing challenge.

This was anotherwhere the average FPS was ahead on the 3080,but at 1080p the 6800M had a higher 1% low,granted the difference was only minorhere. At 1080p the 3080 was just 3% aheadin terms of average FPS, with a larger9% lead at the higher 1440p resolution. Watch Dogs Legion was tested with the game’sbenchmark. This test usually complains that 8gigs of VRAM at the highest ultra setting presetis barely enough, so perhaps results would be alittle different with the 8 gig version ofthe 3080, but with what Im testing withVRAM constraints arent really a concern. The3080 was just 5% ahead of the 6800M at 1080pand almost 10% ahead at 1440p, that is untilDLSS comes out.

With DLSS enabled the 1080presult only increases by 1 frame, whiletheres a larger 13 FPS boost at 1440p,where even the 3080s 1% low is aheadof the 6800Ms average frame rate.

Assassins Creed Valhalla was alsotested with the games benchmark,and this one had some of the smallestdifferences out of all 18 games tested.The 3080 was slightly ahead, but yeah weretalking less than a 2 FPS difference at 1080p,with a slightly larger 4 FPS lead at 1440p,and its not as if above 60 FPS at very highsettings at this higher resolutionis going to be unusable or anything. Call of Duty Warzone was ahead on the 6800M.At 1080p its got a 5% higher average framerate compared to the 3080, but a larger 17%lead in terms of 1% lows, so more stable onthe all AMD laptop.

The 6800M was still in thelead at 1440p, but the gap is much smaller now,at least until we enable DLSS. With DLSS enabledthe 3080 was now ahead at both resolutions,though the 6800M still had a slight edgein 1% lows at the lower 1080p resolution. Fortnite is another eSports title, andone that generally favors Nvidia hardware,which is why at either resolution thisgame had the second largest improvementout of all 18 games tested on the 3080,and thats even before factoring in DLSS,because once we turn that on the 3080 is ableto gain a significant boost. At 1080p were nowtalking about a 36% boost to average FPS anda 55% boost at the higher 1440p resolution.

F1 2021 was tested with the highest setting presetwhich enables some ray tracing effects by default,as denoted at the top of the graph, which may inpart be why the 3080 has an above average leadwhen compared to the other games covered, butyeah the 6800M is still running the game fine.

Instead of talking through the restof the 8 games individually in depth,Ill just blast through them so wecan get into the average differencesas thats more interesting, even if all ofthis testing did take many hours to complete.A larger selection of games is importantto help get a better rounded average.Feel free to pause the video if you want acloser look at any of these additional games. On average over all 18 games tested atthe lower 1080p resolution, Nvidias RTX3080 with 16 gigs of VRAM and max power limitwas just 0.4% ahead of AMDs Radeon RX 6800M,so basically equivalent on average.

Clearlywe can see that some games really seemto favor either AMD or Nvidia, so it candepend on the specific title quite a bit,but yeah once we average out a bunchof games it hardly seems to matter.

If we step up to the higher 1440p resolution wherewere more GPU bound now, things shift more infavor of Nvidia, with the 3080 now averaging a5 and a half percent higher average frame ratein our 18 game selection. Only a small number ofgames preferenced the 6800M at this resolution,but as we saw even with higher settings theframe rates from both were still excellent.Many games that are showing as doing better on the6800M here like Red Dead Redemption 2, Shadow ofthe Tomb Raider and Call of Duty Warzone all haveDLSS support which would of course change things. These are the differences in the gamesthat have either DLSS or FSR support.

As DLSS is only available for Nvidia graphics, theDLSS results are compared with the 6800M at stock,while the Far Cry FSR results are withFSR enabled on both Nvidia and AMD.Anyway for the most part we can see that DLSS isgiving the 3080 some pretty big boosts.

The factis DLSS has just been around for longerso has more widespread adoption for now. Despite generally performing better, the 3080costs quite a lot more money – at least whencomparing the specific laptops that Ive used inthis video. In many cases the 6800M performancewasnt too different and in a number ofgames it was even ahead, all while costingabout $1150 USD less, so of course its goingto win when it comes to cost per frame value,but things would of course change with acheaper 3080 laptop, which do certainly exist,granted theyre also more likely to have8 gigs of VRAM or lower power limits.

The RX 6800M laptop was drawing a littlemore power from the wall in Control,and if you recall in this particulargame the 3080 was performing better.Its worth noting though the 3080 laptopis paired with a 230 watt power brick,so its basically maxed out, whilethe 6800M has a larger 280 watt brick. Content creator workloads could go either way.For the most part the 3080 was ahead inmore of these tests, as per the green bars,while the 6800M in the red bars wasnt far behindin many and was also winning in three of them.

I also want to note that I had no problems withdriver stability on either laptop.

All 18 gamesworked perfectly fine at both resolutions.Unfortunately I havent compared things likethermals and battery life because the laptopchassis are just too different to do thatfairly. It is also worth keeping in mind thatI compared both laptops with the same memory.Unfortunately I dont have the G15anymore because I had to send it backa few weeks ago after testing, but yeah, myG15 came with slower x16 memory by default,so while I did technically upgrade thememory in order to do this comparison fairly,if you did actually go and buy it, it mighthave slower memory. Plus it also doesnt havea MUX switch like the 3080 machine,so that would also hurt performance.

That said, even with these benefits this 3080machine is significantly more expensive than the6800M laptop. If you really want Nvidiaand the better ray tracing performanceand DLSS then you could definitely get a cheaper3080 option for probably closer to $2000.Again as mentioned those cheaper optionsjust might have the lower 8 gigs of VRAMwhich I still think is probably plenty for mostpeople but also possibly a lower power limit,which will result in less performancecompared to what Ive shown here.

You can check out the difference between Nvidiasand AMDs mobile graphics options in these videosnext. Ive compared the RTX 3070 against the RX6700M and the RTX 3060 against the RX 6600M, andthat ones particularly interesting because theywere both tested in the same laptop chassis, so Icould also fairly compare things like thermalsand battery life – Ill see you in that next.
