New Pentium 5 Details - 5-7ghz?
zymano writes "This article gives some details on Pentium 5. It will have 64 bit extensions and maybe a 4000 mhz frontside bus. Quote from the article,'The Pentium V is likely to fly along at between 5GHz to 7GHz, have 2MB plus of level two cache, be built on a 90 nanometer process, and have a stackable design. '"
I swear that the PIV 2.4 Ghz machines I've used are no faster that some of the P III 1 Ghz boxes I've used. We upgraded all our development boxes at work this way and there was hardly any notable improvement... yes, the memory is tricked out so we're not having swapping issues. But you run apache, mysql, and X on one of them and it just doesn't seem like an improvement.
Are they doing a direct trade off where they ramp up the clockspeed and break the instructions down so that less is getting done per clock or something?
Cheers.
I agree. The numbers are impressive but is this going to be like the CDRW wars where you can get 52x but cd's explode at 50something. It is kind of getting rediculous.
The traces do act like a waveguide with no sides. Just a top and bottom to propagate the wave. The problem is fringing effects. That is why its such an accomplishment when they move the spacing closer and closer.
I've noticed that the only time i see significant improvement of a processor is when the cache is larger or bus speed is faster.
Maybe Intel should look into creating a 4Ghz processor with 4Ghz bus and a ton of cache. Because you could do calculations at 7Ghz but if you can only move data at 4Ghz... your only running at 4.
Correct me if im wrong.
