Re: L2 cache size?

Real-world, it may not be noticeable on most workloads. IIRC, a couple of
years back benchmarks of 2MB/core v. 4MB/core CPUs at the same clock speed
showed a 6-10% boost with the additional cache. Said differently, you could
buy a slower CPU with more cache and get roughly equivalent performance
(while likely drawing less power/creating less heat).

Now, some workloads are sensitive to cache. Java, for instance, runs better
on machines with larger caches.

With more L2 cache, more data can be queued up for the CPU to process,
so the CPU would spend less time waiting for the BUS, thus making the
computer faster.

Folks:

As I mentioned earlier ... I just ordered a new laptop.

I'm getting a 2.66ghz Core 2 Duo CPU with 3M of L2 cache.

There were also options for similar CPU's with 6M of L2 cache.

Question I have ... what's the specific advantage of having more L2

cache? Where would the end user notice it?

Thanks!

david
