Oh, that's how you compare test results on openbenchmarking. For some reason I never saw this.
Compared to the 1090T the 8150 is hardly faster, except in few massive parallel benchmarks. That's not very good. But what happened to the "messina" 2600k? In comparison with that it looks terribly awful.
(By the way: This seems to be buggy: http://openbenchmarking.org/opc/1110159-LI-1110131LI24 as the "messina" fails to appear in many of those graphs).
I still think we really need a test with optimized binaries and a patched and optimized kernel to see whether not something goes terribly wrong in software or the problems I have read about are really that severe...
My initial thoughts when reading about Bulldozer (pre release) was: "Wait, we get eight "three-quarter" cores? I want at last six full cores to replace my 1090! Will there be a 12150?"
ATM its seems that one bulldozer Module is 55% faster then one? thuban core: (AMD was promising 80% per CMT core)
So four Modules == 6.2 cores. (... lets ignore the new instructions for a bit ;P)
Imho .. 8150 is a quad core with 50% more power for everything but single threaded apps. The cache trashing due to missing patches/CMT scheduler finish him off.
Yeah that 890FX mobo entry surprised me a bit. Interesting results nonetheless!
Yeah that's my system, still working on it trying to tweak it quite a bit. I flashed the bios with 1.11 on my 890fxa-gd70 motherboard, and it seems to be working fine so far. One thing of interest, it's actually an AM3 motherboard, not an AM3+ motherboard. Ram is running at 6-8-6 @ 1600mhz as well, which may be the reason why I am slower than the other reviewer.
I started with a clean Gentoo install running -march=native -O2 and GCC 4.6.1. I did a trial run at 4.8ghz, and I had it up to 5ghz last night. I don't seem to be hitting any thermal barriers as I ran through the pts/compression benchmark at 4.8ghz and my cpu was at 29C (water cooled).
