Default Prescott

I noticed that Pentium IV Prescott has 1 MB cache.

Did anyone benchmarked it with Prime95? Has it better performances related to "normal" Pentium IV?

No, It has worse performance. See this post and the threads Upgrading to prescott and P4 Prescott - 31 Stage Pipeline ? Bad news for Prime95?.

But I can't find an actual Prime95 benchmark.

Thank you Patrick, I forgot those threads because at that time I was not interested in it

I think I will buy an "old style" Pentium IV 3.2 GHz... unless George has news about it.

While the cache is bigger, apparently the latency is worse.

I read somewhere that Intel favours big slow caches (bigger size in KB, but higher latency). Very bad IMO.

Not really. AMD and Intel's caches have almost always been the same size and have comparable latency.

I suspect the reason why the Prescott latency is higher is because of circuit issues.
