Bulldozer Benchmark Leaks......

Hey guys,

I don't know if you already know about this, but I figured I would post it anyway:

If you read the second article that Ars links to it was concluded that there wasn't much to be gained from looking at the benchmarks due to compiler optimization that may or may not be present, the fact that the chip is an Engineering Sample and a few other factors.

We'll just have to see what happens after production chips start to ship out. I'm still pretty pumped about BD but due to financial issues may not be able to buy one if a BD setup costs more than ~$1200, however I am looking very closely at Llano at the moment and when the time comes may go for that or a cheaper SB setup (again depending on benchmarks and my finances when the time comes to build my next rig).

I did read it. Although it apparently did nothing for you, it may help other people. Thanks

I'd take any benchmarks even vaguely related to Phoronix [or openbenchmarking] with a pillar of salt. Tunnel-visioned focus on sensationalizing little things and a lack of big-picture thinking is that site's bread and butter.

I would say that the data is not very representational.

I know.

Hyperthreading is just an extra set of hardware registers that enables faster thread switching because threads can sometimes avoid having to dump their stack into memory and load it again.

Bulldozer has extra integer units. Two threads can sometimes process instructions in parallel. That has nothing to do with thread switching.
