You know that software-only view will hit a very hard wall... :) you can get dual-core atom in a desktop model, and I thought I've heard of people dropping those chips into netbooks... or maybe just wishing they could.
Sure, hyperthreading is generally better than not, but of course it is a hack and using hyperthreading on a dual core is much better. A single-core hyperthreading-capable processor still has one cpu core. I don't believe that a hyperthreaded CPU has more available horsepower than a non-..., but rather that is a hack to better-handle the software, which hasn't kept up (or been able to, no blame). cheerio & tgif, Ben On Fri, Jan 23, 2009 at 12:09 PM, larry price <[email protected]> wrote: > On Fri, Jan 23, 2009 at 10:18 AM, Ben Barrett <[email protected]> wrote: >> I thought the N270 chip was merely "hyper-threaded" IIRC, >> and not actually having two ores: >> http://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors >> http://www.intel.com/products/processor/atom/techdocs.htm >> > > It's a matter of semantics. > > I'm a software and protocols guy so if the OS sees two cores, it's a > dual core as far as I'm concerned. > > On the hardware level it's a bit murkier than you might think, each > logical core has hardware registers and cache that are exclusive to > them. > > But it's a multi-moot point since for most of the things a netbook is > useful for, faster and more parallel processing cores just means the > CPU is waiting faster ;-) > _______________________________________________ > EUGLUG mailing list > [email protected] > http://www.euglug.org/mailman/listinfo/euglug > _______________________________________________ EUGLUG mailing list [email protected] http://www.euglug.org/mailman/listinfo/euglug
