Joe, <do you think they will keep the p4 L1 cache at 8k or do you see a chance to upgrade it>

I have absolutely no idea. Personally, I'd like to see that L1d cache increased, but that might be too tall of an order, especially if it changes latencies, pipeline structure, timing dependencies, etc. Then again, back when Intel made the transition from Pentium Pro to Pentium II, the L1d cache was increased from 8K to 16K with seemingly no impact to clock speed, so I guess it can be done.

My guess is that for Northwood (Pentium 4 on 0.13u), Intel will leave the L1 cache alone. Then Intel will let high clock speeds carry Northwood beyond anything the competition can even hope for, both in GHz and in overall performance.

Joseph,

The P4 L1 cache is probably stuck at 8K because of it's (low latency) two-cycle access time. This severely restricts the cache size, and any increase in cache size would impact clock speed.

The Athlon architects used a large three-cycle cache, which is obviously the intelligent thing to do.
