Looks like Steamroller had better memory performance than kaveri at stock. Tweaked kaveri in AIDA i can get around 25K read @ 4.7ghz with around 2500mhz single rank memory.
Maybe in PH II X4 L3 Cache helped a lot in multithreading efficiency.
What make it wonderfull my 7.3GHz 6800K with NB almost 4ghz is not much faster than this, that with conditioner
So this is not a benchmark, but score based on value you set that detected by XTU but must finish the test. What make me think this is not a benchmark because variable score is too tight, even if i test XTU with Youtube opened, score is not affected
I got info Zen Opteron is 32 Core (16 + 16 in one die) with 8 Channel DDR4 Memory. So probably Zen Desktop will 16 Core with Quad Channel DDR4. And the most important i hope 40%+ IPC Improvement is from Excavator Core, not from older core. It will fun if memory controller is a beast like 4266Mhz Quad Channel for daily usage
If you need more you can edit with VBE7, im newcomer at extreme cooling. So maybe other can help you. But as far as i know HD 7970 reference is about 225w, so 420w is a lot.
For those who want know BIOS specification, this is it OCP limiter is 420w @ +20%. I found this bios long time ago from other forum but i forgot which one. So i just upload it.
Little Update, still no see LOD effect, so i dont use LOD. Idk this is good result or not...
