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.

well, I care.goatfajitas - Tuesday, January 30, 2024 - link
I do see your point. You can put in some high end cooling and take advantage of the speed. That still doesnt fix the fact that it runs extremely hot and power hungry compared to its competition.ricebunny - Tuesday, January 30, 2024 - link
Highly dependent on application. In games they pull around 125W, roughly the same as high end Zen 4 CPUs.goatfajitas - Tuesday, January 30, 2024 - link
"Highly dependent on application. In games they pull around 125W, roughly the same as high end Zen 4 CPUs."Agreed on some setups. I have seen some equivalently equipped SFF/Tiny desktop setups (with obviously limited thermals) and Intel drops off alot earlier. The point being it runs too hot.

"roughly the same"ComputerBase measured this over more than a dozen games and on average it's 149W for the 14900K and 72W for the 7950X3D, which is less than half. Even the Non-X3D 7950X with 105W uses almost 30% less in games.

It's the enormous heat output that is the problem, not the electric bill.yankeeDDL - Thursday, February 1, 2024 - link
"no issue"? Are you joking?Cost aside, to dissipate 400+W you need massive cooling, and the MoBo needs to be way over-designed.
Intel peaks at 4x the power of Ryzen to, maybe, marginally beat it in few benchmarks. That's not irrelevant at all: this kind of delta in efficiency applies also on mobile (albeit not so extreme): that translates in battery life (and slower performance, as on laptops you can't peak at those levels).

Was this in the 12th gen mobile CPUs?lakedude - Friday, February 9, 2024 - link
"Peak power is an irrelevant metric." maybe to you.Going AMD this time allowed me to save money on the cooler and the power supply. Gonna save money on electricity as well.
I hate the way Intel plays games with their TDP these days. Don't say something is 125w TDP if it can pull over 300w. Call it a 300w chip that can be underclocked or power capped to 125w. Or have it only pull 125w out of the box rather than leave it up to the user to fiddle around with turning it down.

Well, Intel definitely has the advantage when it comes to "not dying when pushed hard" or even "not dying when running at the actual stated specs" but outdate efficiency/IPC, while AMD is the opposite on both fronts.So Intel put the pieces together and said "what if we clock it until 250W turbo TDP while the competition only has 100W at that price point"
