Intel Nehalem, Bloomfield has 8MB of cache
@ 2007/10/24To all of our surprise the future Nehalem processors with four cores and eight threads will have 8MB of cache memory. Yorkfield has 12MB, or should we say two times 6MB as this is still dual chip stitched together chip. Each core in Yorkfield has 3MB cache and it looks that Nehalem will have 8MB.
I would agree whether the performance increase is worthwhile enough to justify an upgrade is a important consideration to any review. However I also think being able to get higher performance for the same $1 spent towards a new system or new mainframe is also important.
Sure, it won't affect Excel that much, but with that logic all anyone needs is a Pentium 4, which is true. However not all consumers cannot make use of all four cores, and not all businesses cannot make use of the extra CPU power. Solely focusing on business computers that run Office products all day is just another small portion of the market.
