iGPU Gaming Performance: 720p And Lower
The reason we test games in CPU reviews at lower resolutions such as 720p and below is simple; titles are more likely to be CPU bound than they are GPU bound at lower resolutions. This means there are more frames for the processor to process as opposed to the graphics card doing the majority of the heavy lifting.
There are some variances where some games will still use graphical power, but not as much CPU grunt at these smaller resolutions, and this is where we can show where CPU limitations lie in terms of gaming.
We are using DDR5-5200 memory as per the JEDEC specifications on the Ryzen 7 8700G and Ryzen 5 8600G, as well as DDR4-3200 on the Ryzen 7 5700G and Ryzen 5 5600G. The same methodology is also used for the AMD Ryzen 7000 series and Intel's 14th, 13th, and 12th Gen processors. Below are the settings we have used for each platform:
- DDR5-5200 CL44 - Ryzen 8000G
- DDR4-3200 CL22 - Ryzen 5000G
- DDR5-5600B CL46 - Intel 14th & 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
The bread and butter of AMD's Ryzen 8000G is in integrated graphics performance, with upgraded RDNA3-based mobile graphics used over AMD's aging Vegas graphics found within the Ryzen 5000G series. Depending on the title at 720p, we can see the combination of Zen 4, and RDNA3 proves much more effective at 720p than Zen 3 and Vega.
In Strange Brigade, we saw a massive 53% uplift in performance when comparing the Ryzen 7 8700G to the Ryzen 5 5700G, with the Ryzen 5 8600G also proving much more suited to gaming at 720p than any other processor with integrated graphics we've tested.
Regarding our retest with the latest firmware, we can see that both the Ryzen 7 8700G and Ryzen 5 8600G performance is marginally better at 720p. The issue with gaming benchmarks is that they typically don't represent sustained loads, and we expect these performance figures to be sustained over longer periods of time with STAPM limitations removed.

On another point, I still think Anand's CPU reviews were better than Ian's. Ian was good but tended to get lost in the details, whereas Anand had an abstraction to his writing, and made computers inspiring, as if you were reading a story. Even the titles were memorable.TheinsanegamerN - Wednesday, January 31, 2024 - link
If you are going by steam, there are nearly as many sub 1080p as there are 1080p gamers. And those sub 1080p users would love the iGPU.If you dont like it, feel free not to read it. Or do your own review if you are so much smarter.

Gamers Nexus has found an Issue with the Ryzen 8000G APUs in the form of some Mobile Variants of the 7000/Phoenix mobile processor firmware settings that should have been removed for the Desktop Ryzen 8000G series Phoenix derivatives. And that has something to do with Laptop/Handheld skin temperature regulation where in order to account for that in laptops/handhelds the processors are being trotted in the Desktop Ryzen 8000G SKUs as if that's in a mobile laptop/handheld from factor device! So watch GN's latest video from today and see that more re-testing may be in order there!nandnandnand - Tuesday, January 30, 2024 - link
It's Skin Temperature Aware Power Management (STAPM).Kinematics - Tuesday, January 30, 2024 - link
The 88 W peak draw is about 25 W above the 65 W TDP, not 35.mikato - Tuesday, January 30, 2024 - link
Are we not doing idle power consumption any more?t.s - Tuesday, January 30, 2024 - link
This depend significantly from PSU and motherboard you're using. anything x70 chipset 24ATX PSU will boost the idle power vs when using x20 and 12VO. But yes, I'm curious too with their setup idle power. My guess, around 50W -> 24ATX 1000W, 6950 GPU.mannen - Tuesday, January 30, 2024 - link
You missed to compare these against the Ryzen 5 7600 and the Ryzen 7 7700 CPUs.That would have been very interesting since they are equivalent (but desktop) parts with the same number of cores/threads. To compare to Ryzen 9 makes no sense since it's not within the same budget class.
I for example am interested in the 8600G, but also looking at the 7600 and keeping my old GPU. Since I don't game a lot, I can easily sacrifice the old GPU but I want to know how much CPU performance I'm giving up.

Well the other commenters here are throwing huge temper tantrums over CPU benchmarks being included in this review, so you may be better off looking elsewhere.lorribot - Tuesday, January 30, 2024 - link
Would have been nice to see a comparison with discrete cards like a RTX2060/3060.
