AMD Radeon 780M RDNA 3 iGPU Gets Benchmarked

[GFreeman]

A tech reviewer, ETA PRIME, managed to get its hands on the ASUS TUF A15 laptop, based on the AMD Ryzen 9 7940HS APU, and run some benchmarks on the integrated Radeon 780M RDNA 3 iGPU, showing that it is capable of delivering playable framerates in some popular games at 1080p resolution. The Ryzen 9 7940HS is an 8-core/16-thread Zen 4 APU with a base clock of 4.0 GHz and a maximum boost clock of 5.2 GHz. It features the Radeon 780M RDNA 3 iGPU with 12 CUs (768 stream processors) working at 2800 MHz. The APU in the ASUS TUF A15 laptop was paired up with 32 GB of DDR5-5600 memory. The system comes with an NVIDIA GeForce RTX 4060 GPU, but the review was focused on the AMD Radeon 780M.

In 3DMark Fire Strike and Time Spy benchmark, the Radeon 780M GPU was 12 and 15 percent faster than the Radeon 680M, despite the other system being equipped with faster LPDDR5 memory. ETA PRIME was also keen to note that the early driver was obviously not ready, and it did crash in some games, so the performance could be even higher when the official driver is released. ETA PRIME benchmarked a couple of popular games with the CPU limited to 80 W, resulting in playable framerates in most of the games at 1080p and medium to high graphics settings. Bear in mind that the system was tested in Performance Mode set via ASUS Armory Crate software. According to ETA PRIME, the integrated GPU was easily overclocked up to 3 GHz, and it would crash at 3.25 GHz, which shows great promise and might be more stable with the final launch driver.



Benchmark results:

• CSGO (1080p High): 130 FPS
• GTA (1080p Very High): 81 FPS
• Forza Horizon 5 (1080p High): 86 FPS
• Fortnite (1080p Medium): 78 FPS
• Doom Eternal (1080p Medium): 83 FPS
• Horizon Zero Dawn (1080p Favor Performance): 69 FPS
• Call of Duty Modern Warfare (1080p Recommended/FSR Perf.): 106 FPS
• Cyberpunk 2077 (1080p Medium/Low Mix): ~70 FPS

this is really fucking impressive for an igpu

 

[kapone32]

I can't wait to get a Desktop variant APU with these Specs. It will make A620 a viable board and for people like me $600 1080P Gaming PCs to sell.

Makes one excited about what will be possible for future Steam Deck's, especially if they stick with the 720p/800p resolution, with an emphasis on faster RAM being more easily available in the future.

At 720P you would be getting over 150 FPS.

 

[Space Lynx]

it is worth noting, its drawing 80 watts in the screenshot. so this will never be in a steam deck 2, etc.

Memories are still slow relative to the maximum supported speed. Graphics performance can still go up by 25-30%

 

[playerlorenzo]

Makes me excited for the new mini pc's and high-end laptops that will be released in the future.

Maybe even desktop AM5 APUs, but time will tell.

am i the only one amazed that this thing has DDR55 ... i mean come on ... we, peasant, are only on DDR5 right now! this is the FUTURE! (well, myself ... lower than lowly peasant... is on DDR4 right now )

DDR5 like DDR4 did before has come back down to realistic pricing. 32GB sets are on average $5 more than DDR4. The thing is all DDR5 works with HWinfo64 to report temps. Where it is still eye watering though is 64GB kits but you don't need 64GB of VRAM yet.

yeah, i know but i mean ... man DDR55! fifty five!

well i am not so much a lowly peasant ... i upgraded recently to 32gb DDR4 3600 from 16gb DDR4 3000

also ... vRAM? eh? 64gb ? damn i only have 12gb now ... oh RAM you meant ... as in system RAM, alright yeah.

Supported speed goes up to 7500 but the type of memory has to be LPDDR5x. That one is soldered down.

That's with a high TDP CPU going at full tilt. Reduce the cpu voltage/clockspeed and you can get the same graphic performance out of ~20-30W - if it is anything similar to the 5600G desktop APU.

I get the feeling that that's the whole APU power, as it has been limited to 80W. So the software probably doesn't have a separate power readout for the iGPU. But it's just my guess.

ETA prime is a great channel, there was a many a 6800U device I wanted, but availability and cost was a nightmare and prohibitive, hopefully U series devices sporting a CPU that carries the 780M will be more readily available, won't expect them cheap though.

Very impressive numbers for an iGPU, imagine it with DDR6 6400-7500! he's already demonstrated faster memory making a big difference on the 6800/680M series.

 

[AnarchoPrimitiv]

Could you imagine what would be possible on a desktop APU with 16 or 24 RDNA3 CUs? What about with v-cache? I'd imagine reducing the calls to system memory would undoubtedly aid an iGPU, or better yet, that which I've been praying for years....an APU/SoC with at least 24 CUs and 4GB of on-package HBM2e/3 that can also be dynamically utilized as an L4 cache by the CPU when the iGPU does not require it. Yes. I know an 8 core APU with such specs could easily be approaching $500, but with double the CUs as the 780m and the on-package HBM, you would easily have more than double the performance of the 780m, and an excellent 1080p high refresh system (or even 1440p ar 60fps with FSR) that would cost far less than one with a dGPU. Not to mention better efficiency, smaller footprint and quiet.

Plus, I think AMD releasing a line of highly capable APUs would be able to disrupt the 1080p gaming segment and would do far more to reign in skyrocketing GPU prices and bring Nvidia back down to reality than an RX 6600 or 6500 (or 7600) ever could. A whole new option in performant PC gaming would definitely demand more attention and consideration that just another low tier dGPU.

Then the shrink down to 3nm and reduced power needs for such APUs could see comlletely new applications we haven't even considered yet.....obviously there's serious hurdles associated with such a product that I'm not seeing, because if it was as easy as I make it out to be, wouldn't AMD have already done it? Or possibly there isn't a sustainable market for such a product and I'm the only one who desires such a creation...personally, I would love to be able to buy a barebones kit based on a similar APU (and even the soldered GDDR) in the Xbox Series X or PS5 (obviously updated with Zen4 and RDNA3).

New benchmarks today in the 7840 Pro show the iGPU 780M is as fast as RX570 in Geekbench 5.

For gaming, it is always much more performance if you build a cheap CPU + dGPU, instead of expensive APU (which this is- it is a rather big die made on a latest 4nm node).

Yep if that arrives I'm building an ITX for under the TV

 

[david salsero]

this is really fucking impressive for an igpu... I bet the price on these will not be affordable though, most look to be bundled with a dedicated gpu as well, which just sucks... would love this chip ina $499 portable small form factor laptop for work.

Honestly, your comment is ridiculous, the most powerful iGPU on the planet with which you can play AAA games, Video rendering, 3D applications, CAD and you want it for $499 when the Intel Xe with which you can only play minesweeper already costs you $600.
AMD ZEN 4 7040 Phoenix= LPDDR5 + RDNA 3 + USB 4.0 + HDMI 2.1 + artificial intelligence with XDNA architecture developed by Xilinx and all at 4nm vs 10nm from Intel that consumes more power and gets hotter and deteriorates the useful life of the processor.

 

[hs4]

it is worth noting, its drawing 80 watts in the screenshot. so this will never be in a steam deck 2, etc.

The 780M should maintain about 85% performance (Timespy 2700pts.) even at 25W, so it can be said that the tuning is wrong. The Meteor lake GT2 is almost identical to the A370M (Timespy 3500pts. @ 35W), with the tensor engine removed and the node advanced one generation. This would make it a serious competitor to the 780M.

 

[R0H1T]

yeah, i know but i mean ... man DDR55! fifty five!

Yeah but bigger, or higher, isn't always better

+1 true but it is Gigantic the advance of AMD in the average performance in AAA games of the AMD Radeon 780M iGPU (RDNA 3) with CPU limited to 80W and low frequency DDR5 memories in laptops under 2.2 lb imagine when using FidelityFX Super Resolution 3.0. where it goes from 60 Fps to 120 Fps. For CAD applications, video rendering and 3D enough:

CSGO (1080p High): 130 FPS
GTA (1080p Very High): 81 FPS
Forza Horizon 5 (1080p High): 86 FPS
Fortnite (1080p Medium): 78 FPS
Doom Eternal (1080p Medium): 83 FPS
Horizon Zero Dawn (1080p Favorable Performance): 69 FPS
Call of Duty Modern Warfare (1080p Recommended/FSR Performance): 106 FPS
Cyberpunk 2077 (1080p Mixed Medium/Low): ~70 FPS
I'm crazy to see ultrabook with this AMD ZEN 4 7040 Phoenix processor they will all sell.

But then it has the majority of that power budget just for the GPU, because TimeSpy is primarily a GPU bench.
Run a game that also sips CPU power and your 25W limit has a totally different result.
