I would believe you if you said Phenom II could match the FX and A- series at the same clock speeds, which is backed up by our testing, but the Athlons are stuck way at the bottom of the list. However, the FX and A- series are based on a 32 nm die while the Phenom and Athlon are based on 45 nm. This means that the FX and A- can run cooler at the same speeds, giving more thermal headroom to allow for higher overclocks, resulting in more speed.
Well that's interesting...

Athlon II Regor is a different beast. It features a whopping 1MB of FAST L2 cache per core (PhenomII has only 512kB per core) and this makes it to almost match the level of performance of the Phenom II with 6MB of SLOW L3 cache. (FYI, there are 2 versions of the Athlon II - one with 512kB of L2 cache per core and one with 1MB. The dual-core 1MB version is much better and has higher IPC) Overclocking the Regor CPU means using faster RAM and increasing the memory controller speed as well, so the L2 cache of the Athlon II becomes even more efficient. The Athlon II just loves fast RAM. On the other hand, using high-speed RAM on a Phenom II doesn't have any efect on its performance. It may even reduce the performance by 1%.

The OP is probably sitting higher due to his overclock) The (semi-)synthetic POVRay Dolphin-Benchmark is not a good benchmark. It only tests one edge case. Real world Dolphin performance results are very different (you won't see that much of a speed increase) www.cpubenchmark.net is a better CPU benchmark (go to the the single threaded performance chart page) An Athlon II X2 overclocked to 4Ghz scores ~1500 in the best case scenario (fast RAM, optimized OS, power saving features disabled). Impressive, isn't it? Now compare that score to the other AMD CPU architectures clocked at 4GHz , but the benchmark must be done with with Turbo Boost DISABLED in the BIOS. 11-02-2014, 09:31 PM
I would like a screenshot of that number. Since you're so sure of it. The A10-7850k seems to be able to do those results without having a best case scenario.

Even if you take that POVRay is an edge case, an even more generic chart like that isn't even an edge case scenario since it doesn't measure dolphin performance in anything. Haswell chips are faster than anyone expected in Dolphin for example (and emulators in general). 11-03-2014, 04:53 AM
If you're looking for a good website to compare CPUs, try CPUBoss.com, not cpubenchmark.net, because cpubenchark falsely skews data with multiple cores,

CPU World is other good site for comparing CPUs.
