AMD Ryzen 9 7900 iGPU Overclocking Pushes Performance Up to 42%

[AleksandarK]

According to SkatterBench, a website known for incredible overclocking attempts, we get to see AMD's Ryzen 7000 series integrated GPU get up to 42% performance improvement from overclocking. Specifically, the SKU used in the attempt was the Ryzen 9 7900 non-X model with 12 cores and 24 threads, clocked at 3.7 GHz base frequency and 5.4 GHz boost speed. The SKU contains a basic AMD GPU integrated into the package; however, not meant for any serious gaming tasks. Nonetheless, it is interesting to see what a two-core RDNA2 GPU clocked at 2.2 GHz managed to achieve once overclocked. The memory clock of the GPU is set to 2.4 GHz at stock.

Running at the base voltage of 0.997 volts under Furmark workload, the iGPU consumes around 38.5 Watts. However, the overclocking attempt pushed the voltage to 1.395 Volts, resulting in a 3.1 GHz iGPU frequency. The GPU Memory clock is now set to 3200 MHz, and the GPU+SOC power is 60.689 Watts, almost double compared to the stock settings. The overclocker used a GFX curve optimizer with various system tweaks to achieve these numbers. While the OC attempt was successful, the most significant performance improvement was a 42% increase, with some game titles averaging less. Below, the blue bar indicates stock, while the green bar indicates OC'd performance. You can check out the YouTube video as well to see more details.

More interested if we can do this with phoenix point lol

I'd like to see this replicated, but with a much beefier iGPU SoC that AMD can make using RDNA3. I still believe there's a market for desktop APUs with just enough GPU horsepower to enjoy popular titles at 1080p, especially with the help of FSR and so

Very nice, academically speaking, but adding 42% to nothing is still- nothing.
All you achieve by that is to get the same video signal to your monitor with 50% more wattage consumption (20w), as this is what ZEN4 iGPU is meant for. That 20w is coming from the main core budget, so less juice for the real player.
Useless, like going LN2, but still nice from purely OC perspective.

English is not my native language, but does anyone else think title doesn't make sense?

"AMD Ryzen 9 7900 iGPU Overclocking Pushes Performance Up to 42%"

So by overclocking the performance reaches up to 42%? 42% of what, Intel CPUs?



But then again, 42 is the answer to the ultimate question of life, the universe, and everything.

Yeah, I'm waiting for a potential 7600G with an 8 CU gpu inside too. From my calculations it would be faster than the fastest Polaris cards.

Especially since low/mid-range GPUs are simply either not available, or cost more than a CPU (and have less performance than a six year old mid-range card that cost half as much).

Pretty sure the stock iGPU isn't consuming 38.5W at 1.0V VDDCR_GFX..........major alarm bells going off. Whole IOD power, maybe, so minus about 10-15W for the rest of the IOD, sounds reasonable. A 2.3GHz Vega 8 draws about 40W on its own; this 2CU unit isn't doing 40W at ~2GHz clock.

Skatterbencher has some great info as to AM5's design, but clearly isn't familiar with Vega power reporting in HWInfo before. iGPU core, iGPU SOC and "ASIC power" basically just report whatever the hell they want and make no sense whatsoever, it's wild. ASIC power at 0W during full 3.1GHz iGPU load is pretty telling.

Hopefully Phoenix Point have a much stronger memory controller to give the core the bandwidth it deserves.

Good to see that GFX Curve Optimizer is finally useful because GFX frequency isn't limited to +200. It also looks like little to no Vdroop at full tilt 3.1GHz? Very promising

Nice...

Speaking of... when will Techpowerup release their 7900 review?
It was mentioned as comming soon in the review of 7600 and 7700

Over clocking pushes the performance in certain tasks up to 42% higher of its non overclocked counterpart.

given the context of the website and and topic of overclocking the initial title should be clear for the reader IMHO.

Sure it is. But wording it differently like this sound more normal to me?

"AMD Ryzen 9 7900 iGPU Overclocking Raises Performance By Up To 42%"

 

[Chrispy_]

Fun, but entirely academic. The iGPU in Zen4 is a bare-minimum that's not intended for anything demanding. If you need GPU performance from the IGP you're holding it wrong.

Only serves to highlight the efficiency issues in the broken RDNA3 desktop cards

 

[Denver]

Too bad both DDR5 and motherboards are expensive making desktop APUs less attractive and probably shouldn't even be in AMD's plans.

 

[W1zzard]

> Below, the blue bar indicates stock, while the green bar indicates OC'd performance

And the chart starts at 90% .. kinda misleading .. I expected better

Nice...

Busy with other processors right now

Somewhat related, I feel like iGPUs are purposely constrained by business decisions over technological ones. Looking at the SoC in Xboxes, Playstations and Apple Mac M series, PC laptop and desktop iGPUs look anemic in comparison at best.

Well yes, just as 99% of all other things

Zen 4 iGPUs are RDNA 2, not RDNA 3. At least do the most basic of research before making a stupid comment.

 

[thegnome]

42%, lord. Imagine if we had fast enough ram to do this on the full 12 CU apu's. Or any gpu in general, 42% with just overclocking is unheard of, even for the last 10 years.

That depends on your definition of "GPU performance". The 5600G I have now is about as strong as the HD6950 I used for a good 7 years. That's certainly a lot of GPU performance, enough even to run even modern releases at playable framerates.

So that makes it very interesting that the gimped, 2 CU RDNA2 on the Zen4, has so much head room.

Consoles have custom silicon, granted it uses the same cores and GPU tech as desktop hardware, but it's got a MASSIVE unified memory bus. Such a chip on socket AM4 would be choked so badly there would be 0 point. People also forget said consoles would/are sold at a loss, how big of a market do you think there is for a $750 APU that will either require its own proprietary mobo or need something like the threadripper socket and memory bus to be remotely close to usable?

and Apple Mac M series,

Those are a totally different beast. Built on a more modern TSMC process in a tightly controlled vertical monopoly. Much like console performance, you cant have that level of SOC performance if you want an open ecosystem with multiple competitive manufacturers. And again, much like consoles, said iGPUs are paired with a massively wide (soldered) memory bus.

PC laptop and desktop iGPUs look anemic in comparison at best.

On desktop AMD has been sandbagging, refusing to offer us that sweet rDNA2 APU. Laptop it depends, get a model with a 680m and LPDDR5X and it's awfully speedy compared to a model hamstrung with DDR4 3200.

Mostly mobile and few enthusiast/workstation I suppose.

AMD did announce laptop APUs at CES but I dont remember when they are coming out. I would guess maybe 3-4 months away.

The last overclock I had that high was on a 8800m gts, I remember getting 31% on the core and 35% overclock on the memory. Back in 2008.

Are there any one stop shop benchmarks for popular games on this iGPU? Games like CoD, Fortnite, Rocket League, Roblox, Minecraft, Dota 2, GTA5, Destiny 2, War Thunder, TF2. Just out of curiosity really.

 

[mechtech]

Still waiting for a decent quad/hex core with a big fat igpu with full stack of encode/decode codecs.

Matrox Maevex, Mura, Monarch...Much less power consumption than graphic cards for general purpose.
