You mean like this?
Glad you bring that up, i've specifically done a lot of x264 benchmarking. And yes, the OC hack does affect (reduce) performance in x264 (just for clarity, x264 is the encoder used by handbrake)
x264 is very highly multithreaded - like 99.9% parallel, which is way, way more than any game on the market or is even possible with dx12. See the practically perfect scaling onto 16 threads for the 5960x.
For x264 encoding, a 9590 at 5ghz and a 6600k at 4.5ghz have about the same speed, as parallelization isn't a concern at all.
That lack of parallelization (and amdahl's law*) lead to usually having those ~25-80% performance leads in games.
My thoughts exactly. We've seen in two games already that AMD can easily match Intel's i7's (8350 being between a 2500K/4670K and 2600K/3770K/4770K) as long as the engine makes good use of threads.
"Between a 5 year old i7 and a 2.5 year old i5" isn't "matching Intel's i7's". Falling between a 2500k and a 4670k means losing hard to a 6600k (i5). Those engines in particular that you speak of are the ones where i5 is about 20-40% faster than FX 8-thread and are some of the best threaded game engines. They're not the ones to be most concerned about - though they run worse on weaker CPU's, it's not as completely gamebreaking as some other games/engines.Edited by Cyro999 - 2/15/16 at 8:05pm
