CPU Benchmark Performance: Encoding
Another of the interesting elements of modern processors is encoding performance. This covers two main areas: encryption/decryption for secure data transfer and video transcoding from one video format to another.
In the encrypt/decrypt scenario, how data is transferred and by what mechanism is pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning towards improving software security.
We've updated our list of encoding benchmarks for our 2024 CPU suite to include some of the most relevant and recent codecs, such as AV1, HEVC, and VP9. Not only this, but we have also included FLAC audio encoding as well as WebP2 image encoding into the mix to show not only how the latest processors perform with these codecs but also to show discrepancies in performance throughout the different segments.
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
When it comes to encoding performance, as expected, the performance of both the Ryzen 7 8700G and the Ryzen 5 8600G doesn't quite reach the levels of the typical desktop chips. Performance in this area is where we expected it to be, again with the Ryzen 7 8700G beating out the previous Ryzen 7 5700G APU, and the same with the Ryzen 5 8600G and the Ryzen 5 5600G.
With the latest firmware, which removes the STAPM power limitations, we can see that it doesn't really affect the Ryzen 7 8700G in our encoding tests. We do, however see some bumps in performance without STAPM limitations on the Ryzen 5 8600G, although in the vast majority of use cases, the performance is very marginal.

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.
