If we are allways looking for the last solution in informatic we wil never buy one.
When I bought I7 920 I just knew what I was doing. Off course briefly we will have the 6 Quad Core with the 32 nm technology, and better yet.
But I am sure that I was buying the first of a new era of processors.
The huge problem of the FSB is finished. Now we have the Quick Path Interconnect, with it's 20 lines of serial transmission for 16 data bits, and with about 26 GB/s bandwidth.
And for the first time we have, in Intel, a direct comunication with memory, in 3 chanels, what means that for each access in a burst of 8, you can read from main memory about 192 Bytes of data, I mean, you can improve a lot the cache performance augmenting it's block decreasing the time of access.
And as in I7, Intel placed for the firs time significant amounts of cache (32 x 2 B of first level cache - Data and Instructions - for each core, 256 B of Level 2 cache for each core and 8 MB of Level 3 cache comon to all cores) in the CPU chip, I really think that the 3 chanell option is correct.
If you are thinking of the NAND discs (Flip Flop Discs), there I don't yet know what we shall expect, but, as cache type memory that they are, if ever they will get where that kind of memory goes, everything is questionable (Cache, main memory and Hard discs). Remember that the obstacle now in those discs is the time flash memory needs to change the state of the stored charge in transistor. A bigger problem that the one we have know with the capacitors of RAM memory.
So, I really don't see why I must not expect that the software evolution will not take proffit of all these performances, with a 64 bit OS, during the expected reasonable life of I7 920, which is not an end of line processor but a really inovative one.
And, if you buy a Ferrari, you will shurelly not put Diesel on it.
Excuse me for the long explanation. Intel doesn't pay me for it.
