Benchmark Results – CPU Tests
PCMark 10 measures overall performance and user experience in a host of “real world” applications. Tests include launch time, and some tests benefit from GPU accelerated compute.
Interestingly, PCMark 10 showed noticeable gain from the GPU overclock. As far back as 2013 AMD were producing adverts touting the benefits of GPU compute, in their own way. PCMark includes some conventional GPU loads, but the Spreadsheets test also uses the GPU with OpenCL. This is an implementation of the HSA technology people were excited about back in the day.
PCMark 10 also shows relatively impressive improvements from pushing up memory performance. Nearly 5% is added to the CPU+GPU score when the memory on the Athlon 3000G is also overclocked.
Based on Maxon’s real-world rendering software, Cinema 4D, Cinebench R20 renders a static ray-traced scene on the CPU.
Cinebench is conventionally not memory sensitive, and R20 bears this out. Overclocking the core on the Athlon 3000G produced satisfying gains, the memory less so.
HWBOT x265 (1080p)
HWBOT x265 is a popular benchmark among extreme overclockers. It runs an HD video clip through the open source x265 encoder, and returns the average processing speed in FPS.
HWBOT x265 doesn’t seem all that memory dependent on the Athlon 3000G, but gains well from the CPU overclock.
7zip with Benchmate
7zip has a built-in benchmark that measures compression and decompression performance. Benchmate, which is mainly verification software for competitive overclocking, provides a convenient wrapper.
7zip benchmark is quite variable but shows a reasonable benefit from CPU overclocks. Memory OC isn’t as important but does show solid gains.
3DMark Fire Strike Physics
According to AMD, Fire Strike Physics represents CPU performance for gaming. Who are we to argue? What it does do is replicate some of the more processor-intensive moments. Fire Strike Physics tests soft-body simulations with the open-source Bullet physics library.
Gains from memory OC were minimal, but the CPU overclock scaled well.
