Newer UCBench build with XOP support, ok to use?

I'll have a look and compare, meanwhile stick to previous version.

 

Ok. Thanks! :)

According to my testing there was no difference in the score, but the newest CPU I've tested was Thuban.

There might be a difference with Bulldozer/Piledriver.

Is the score the same ?

 

Using a processor without XOP support, score is the same.

But when you use a processor with XOP support, the difference is HUGE:

 

A10-5800K @ 4.77GHz using newer UCBench:

A10-5800K @ 6GHz using old UCBench:

XOP was introduced with BD, it's the equivalent of AVX/SSE5.

His versioning number is confusing, the software was uploaded recently but it's labeled as 2011 wth.

Is there a trick to use XOP? Running win 7 here, and ucbench crashes immediately if I select XOP. ANYTHING else runs fine. This also happens at stock.

On XP you don't even get the option to run XOP. Is that 64 bit only?

 

XOP is AVX, so 7 SP1 / R2 SP1 / 8 and on linux with kernels 2.6.30+

Thanks for the confirmation. :)
