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.

guys WHY would you use a CPU only test in a CPU REVIEW??!?!?!?t.s - Tuesday, January 30, 2024 - link
Cause it have best iGPU in its class. If you won't test that, why bother testing, as it's almost certain that 7700x or 7700 will be better.AndrewJacksonZA - Tuesday, January 30, 2024 - link

Ok, and in the CPU bench section they use a CPU test. How would you know if a 7700 would be better in CPU load if you dont test it?AndrewJacksonZA - Tuesday, January 30, 2024 - link
guys WHY would you only test PART of a CPU in a CPU REVIEW??!?!?!?TheinsanegamerN - Wednesday, January 31, 2024 - link
How DARE we want to see what a CPU does in a CPU review. WAAAH I NEED IGPU OR ILL CRY WAAAAHFWhitTrampoline - Tuesday, January 30, 2024 - link
Because AMD does not support ROCm/HIP for its iGPUs and its ROCm/HIP for consumer dGPUs is lacking as well on Linux. And the Blender Foundation starting with Blender 3.0/Later editions has dropped supporting OpenCL as the GPU compute API. And so since Blender 3.0/later the Blender Foundation only supports Nvidia's CUDA for non Apple PCs/Laptops and Apple's Metal for Apple silicon for Blender 3D 3.0/later editions.So without any Ryzen iGPU support for ROCm/HIP there's nothing to take the CUDA Intermediate Language Representation(ILR) and convert that to a form that can be executed on Radeon iGPU/dGPU hardware. And for Intel's iGPUs and dGPUs it's Intel's OneAPI/Level-0 that does the translating of the CUDA ILR to a form than can be executed on Intel's iGPU/dGPU hardware and for Intel that OneAPI/Level-0 works for Windows and Linux!
Blender 3D generates CUDA PTX ILR and All GPU Makers us Intermediate Languages for GPUs so GPU makers/others ship no pre-compiled binaries where software gets directly compiled into the GPUs Native Instruction Set in advance. And that's so the ILR code remains portable across OS/Ecosystems and GPU makers are free to modify their GPU ISA and still maintain comparability with software that only gets compiled into a portable Intermediate language Representation(ILR)

Edit: maintain comparabilityto: maintain compatibility
I hate Firefox's Spell Checker its a Train Wreck as always!

Feels like these APUs deserve a DRAM scaling article comparing the IGP performance.GeoffreyA - Tuesday, January 30, 2024 - link
Yes, that would be a nice one. Always necessary for APUs.
