The question is, how much will the L3 help when a branch prediction fails and the pipeline gets thrashed? For P4, you're screwed no matter what when the pipeline is emptied and the execution starts over at the other leg. For CPUs with shorter pipes, it's not that bad.

I'm trying hard to see what branch mispredicts have to do with extra cache.

The extra cache is there to try to lower the memory gap between the Athlon 64 and P4. Athlon 64's memory controller is on-die for low latency (70ns), the P4's for system RAM is somewhere about 90ns right now, but adding cache will lower the average latency even more.

oooooooh!!! it's EXTREEEEME!

I dare you to touch a P4 running w/o a heatsink and tell me it's not extreme.

[monolith94]

I dare you to stop a rhino in it's path by pure force of will.

[Asher]

Make it a double-dare and it's a deal.

[monolith94]

triple dog dare you!!!

[Asher]

Them fighting words!

Indeed, I'm surprised that at the sight of them you haven't rolled over and surrendered yet.

Oh, wait, that's the french, not the canadians. Never mind...

So this is what Asher is masturbating over these days . . .

--"This ain't no Apple "L3 cache" bull****, but the real deal -- same cache used in the Gallatin Xeons."

That's the inclusive L3, right? Not as impressive as it could be, then. Certainly not as imipressive as they'll market it ^_^ Intel does follow Apple in that regards (well, all companies do) although they aren't quite as bad.

The value of the L3 cache is fairly debatable for a desktop chip. The 512 k to 1 M transition on L2 has already reached the point of diminishing returns for the kind of things most people do with desktops. People who had been using Xeons could now switch to these, but we'll have to wait for the benchmarks to see if anyone else gets any real advantage from this.

Wait a few weeks and prices will drop like a rock as the new processors are released at the rate of one per month for the next two months.

****, I just bought a P4/2.8GHz/800MHz system. How much faster are these new Prescotts going to be?

I can't wait to get this. I'll be playing an extremely grueling game of Civilization in my ExtremeComfort3000 computer chair, working my MS ExtremeMouse like no other.

And after conquests?...CIV3 EXTREME!!!!!


oh boy.
