AMD Radeon 680M (Ryzen 6000 "Rembrandt" iGPU) Proves its Mettle with Cyberpunk 2077

The Radeon 680M integrated graphics powering the AMD Ryzen 6000-series mobile processors is proving to be an entry-level discrete-GPU killer. TechEpiphany posted a video presentation showing the iGPU's real-world gameplay performance with the AAA title "Cyberpunk 2077" at Full HD (1080p), with a little help from FidelityFX Super Resolution (FSR). TechEpiphany used an ASUS TUF GAMING F17 notebook powered by an AMD Ryzen 7 6800H "Rembrandt" processor that has the full Radeon 680M iGPU unlocked, with all its 12 RDNA2 compute units (768 stream processors), 12 Ray Accelerators, 16 ROPs, and 48 TMUs, enabled. The notebook also features a GeForce RTX 3050 Laptop GPU, but for this testing, it was disabled.

The first part of the video shows the game running at 1080p and Medium-High settings, with FSR set at Ultra Quality. Here, the iGPU is managing 30-40 FPS. Real-time ray tracing is disabled. In the second part, they enabled ray tracing and FidelityFX Super Resolution, but this is where the iGPU runs out of steam. Frame-rates drop to unplayable levels, but there still aren't any noticeable visual artifacts or rendering errors typically associated with iGPUs made to render games above their pay-grade. It's still impressive to see that AMD following through on its promise of bringing 1080p gaming across a broader range of titles. The TechEpiphany video presentation can be watched in the source link below.

Computerbase.de tested the Ryzen 9 6900HS last week. In their small sample of games, the IGP was slightly faster than a GTX 1050 Ti. This is with DDR5-4800. If this comes to the desktop, we'll be able to see the full potential of the IGP. All in all, it's very impressive, and would have been even better with a similarly sized cache as the 6500 XT.

Desktop chips with these Navi GPUs are gonna be badass, however the parts where they make the most sense (R5 nad R3) are most definitely not going to have 12 CUs.

Post GTX 1050 Ti on an iGPU is truly amazing.

Can't wait for these to be supercharged by LPDDR5X

Did we watch the same video? The guy has the game set to 1080P resolution, almost every setting is on bare minimum, RT off, and only FSR is set to ultra quality. Game is around 30-40fps. With RT on, it's barely running. Discrete GPU killer?

Whoa! @btarunr, a major error here. The game is not running at Ultra settings, it is running at custom medium-low settings with FSR at Ultra Quality. That's quite a difference.

Edit: I see the video description has the same error. Still, it's clear in the video at ~0:10-0:17.

But will it run Terraria??

I remember old motherboards had a gddr chip soldered on for integrated back in the day.

I'd wonder how integrated would perform with a motherboard had 4GB of HBM2 or GDDR6 soldered on dedicated for it?? Be even cooler if they could put a so-dimm socket on mobo with GDDR5/6 so you could upgrade ram/speed for the integrated graphics.

FYI a GeForce GTX 1050Ti slot-power only (Asus Phoenix) with a +150 OC on cores and memory will get 16.8fps avg with 11.6fps 1% lows at 1080p Ultra in CP2077's easy-to-run built-in benchmark.

I'll set it to Low + IMO necessary PQ improvements and FSR Ultra Quality to see how that goes. Actually I had that set already and I think it's in the high 30s, but let's see this time.

Edit: Low + Med Textures, Low Shadows, Med Vol Cloud Q, Low SSRs, +FSR UQ:

41.6 fps avg, 27.6 fps 1% lows

I'll have a look at the settings in the video next and set the same. However I'm using an i7-4790 in a Dell Optiplex (!) with 16GB 1600 CL11 Dell crap ram, so my CPU is, ehm... barely decent? But also a reasonable machine to pair a slot-power 1050 Ti with...

Matching their settings (IMO these looked worse than mine):

42.3 fps avg, 27.4 fps 1% lows

Their tested scene is very early in-game, maybe I can try that next.

A single SO-DIMM has a 64-bit bus, so that wouldn't be particularly nice - you'd probably be better off with shared LPDDR5. HBM would be somehting, but HBM needs to be on-package - it isn't designed to handle the trace lengths and resistance of having a socket and a bunch of traces between it and the connected chip. That's the main argument against motherboards with graphics memory onboard - bandwidth would be a real issue. Of course that's assuming they would design a socket with enough pins to accommodate that in the first place (considering that it would be unused or not really necessary on the vast majority of PCs).

It's 32 ROPs on Radeon 680M, not 16 ROPs. The half-cutted Radeon 660M has 16 ROPs.

Linus tech tips showed the 6900Hs iGPU destroying Intel's 12700H iGPU for 1080p gaming. This is a great (and overdue) update. The 6900HS would be my next laptop APU if I were in the market. Just imagine how good Zen4 + RDNA3 iGPU's will perform, we'll be able to play 1080p with high settings and possibly RT as RDNA3 is said to more than double RT performance. Still even Phoenix APU's with Zen4 + RDNA2 will be superb.

I'm utterly confused with how AMD and Intel do things. Realistically cheaper SKUs and specially U-series SKUs should be getting full fat iGPUs.



Traditional product segmentation is specifically egregious in AMD's case. Their GPU encoder sucks ass, you couldn't do any ML workload with their GPU, their GPUs don't have special sauce like AVX-512 or CUDA. At least with bigger iGPU (a la 12 CUs) you could justify dGPU-less AMD laptops for light gaming. But NOOO!!! The idiots at AMD can't think outside the box and slapped the biggest iGPUs at higher end CPUs where it'll be a glorified hamster powering the desktop and video player.

You don't seem to pay much attention to how laptops are specced. High end CPUs/APUs are extremely common across all price ranges, meaning that the 12CU 6800U, for example, will likely be easily found dGPU-less. The same is also becoming more common with H SKUs - Asus has announced a dGPU-less Flow X13, for example (there are also RTX 3050(Ti) versions). I think the cut to 6 CUs is still far too much, but this is comptelely normal - and 6 RDNA2 SKUs should still outperform any Vega iGPU. It will be significantly weaker, but still usable for light gaming.

As for that bottom paragraph - no GPU supports AVX, CPUs do; CUDA is proprietary Nvidia technology, but AMD has done a lot of work to make compatibility layers for developers; and as I said above, the laptop world doesn't work in the "higher end CPUs in higher end laptops" way.

Edit: as an example, looking at laptops at Newegg and filtering for 10th gen Intel i7s or newer and Ryzen 7 5000 (6000 isn't in their system yet, looks like), there are 79 options in the $500-750 bracket and 698 in the $750-1000 bracket. The cheapest ones are 10th gen, but you can find 11th gen i7s and Ryzen 5000U from ~$600-650. You really don't need to buy a premium or dGPU-equipped laptop to get a higher end CPU.

It looks interesting... What would be the performance with Samsung's ultra fast 7500mhz LPDDR5x ram modules ? can it beat a gtx 1650 or rx 5500 ?

You missed an important phrase before "discrete".

Nope. Again, did we watch the same video? The guy sets it all to low, with few things at medium. FSR at ultra quality.

LOL, the second coming of Jesus aka RDNA 2 IGPs is going to disappoint a lot of people who are irrationally expecting an IGP to not suck.

I fix that for you. I understand how some people feel, but the reality is that you can only put so much in a chip before it turns into a space heater.

It's still a significant improvement though. I mean, this is an iGPU delivering playable framerates in Cyberpunk 2077 at 1080p. Yes, it needs FSR to get there, but that is nonetheless seriously impressive. You obviously shouldn't be expecting a mid-range or high-end dGPU killer - that's an absurd expectation - but for what it is, this is great. Heck, the 8CU version in the Steam Deck even performs admirably.

Yep. Again, @btarunr, what gives? You seem to have corrected the article, but corrected it to new and different inaccurate information? Settings are medium-low, not medium-high. Is muscle memory getting the best of you? :P

That would be awesome but the cost to develop a feature like this simply would be worth thr return on investment for the very few diy builders that would take advantage of it. That being said, if all theajor players agreed on a standardized implementation and oems started to use it, I could see it being worth the cost to develop and being able to increase the quantity and speed of the gddr would be a great feature.

I would love to see one of these processors in a desktop with even faster RAM, higher power envelopes, and higher frequencies to see how much faster thry can get in their current implementation.

I see no point in testing with RT on. Consider the fact that even the RTX 3050/ 3050 Ti dedicated laptop solution can barely survive with RT enabled, I won’t even imagine an iGPU now to be able to do that while still delivering decent framerate even at 720p.
