For lightweight work like web browsers with JavaScript stressors, the Ryzen 5 8500G wasn't particularly special...

Or for WebAssembly, the Ryzen 5 8500G wasn't a standout performer.

But where things became much more interesting was when moving to multi-threaded workloads or those that can leverage AVX-512... This sub-$200 CPU still has AVX-512 including on its Zen 4C cores and the same common ISA across all Zen 4(C) products. With OpenVINO on the CPU cores, the Ryzen 5 8500G was not only faster than the Core i3 14100 and i5 14500 but could even surpass the Core i5 14600K.

The OpenVINO tests are solely on the CPU with no Ryzen AI NPU support for OpenVINO at least not yet... But thanks to Zen 4 with the efficient AVX-512 implementation, it's a stunner for such workloads even in the budget Ryzen 5 8500G.

Not only was the Ryzen 5 8500G outperforming the Core i5 CPUs but it was doing so at a fraction of the power! The Ryzen 5 8500G while running OpenVINO was pulling just around 53 Watts with a peak of 57 Watts -- little more than the prior generation Ryzen 5000G parts.
