[ARS] Bulldozer trades blows with Sandy Bridge

The figures above posed by w00key do seem legit, but they're worst cases. In most games, BD trades places with a 2500K, in my own Fallout New Vegas testing, it beat my Phenom II X4 (3.7 GHz) by around 20%. The 2500K beats my Phenom II by the same 20%.

It's hilariously overclockable. Jury-rigging the biggest heatsink I could find, a ~7 year old Coolermaster Hyper6+ (which doesn't fit AM2/3) hacked into a pretty cheap Gigabyte GA990XA-UD3, I got 4.85 GHz out of it. At that kind of clock, the 2500K was looking for its parents with tears in its eyes, losing out on single threaded benchmarks by 10% and multithreads.... well, it wasn't really funny anymore. I'll share with you this:

Code:
x264 encoding
1080p
BD 4.85 12:33
2500K 3.8 18:56
PII X4 3.7 21:30

720p
BD 4.85 8:40
2500K 3.8 11:01
PII X4 3.7 15:15
this a repost?

EDIT: due to having a bad mobo and stock cooler he only OC'd the 2500K to 3.8ghz. mine is on the stock cooler atm...anyone mind benching theirs at 4.8 in those same tests?

I would have preferred that it trade blows with the i7 2600K instead, if this CPU performs worse than a 2500K in most cases despite having more cores, threads and cache then Bulldozer is an epic failure.

I'll believe nothing until the CPU gets released.

i think thats a stupid comparison.
he said he could not put the multi of 15 more then 38.
so comparing bulldozer at 4.85 vs a 2500k at a unknown speed is not fair.

for a fair clock to clock bench both cpu should be at 4.5 for example.

...and then on the 12th several AMD enthusiasts jump off a tall building.
How could you live with yourself, AMD?

On a serious note, about 17-19 hours to go until official reviews are supposedly posted.

i have a hard time believing that this is true at all. Im not an amd processor fan, but i will wait until release to see benches. I am still waiting on someone to give intel a piece of humble pie, but i dont think BD will do that and makes me sad.

if you have good cooling, could you run the same x264 tests? mine is stock cooling.
