It is perfectly possible. You buy them from companies that supply the professional CAD market and it is relatively easy to find 32 core, dual processor, twin graphics card systems for less than $5000.
- tedunangst 14y agoI think you mean 12-core. Who's selling 16-core CPUs? Also worth pointing out that the Mac Pro is one such system as you just described.
- reitzensteinm 14y agoAMD makes 16 core Opterons (codename Interlagos), however they're slower than the latest 8 core Xeons. http://en.wikipedia.org/wiki/Opteron#Models http://en.wikipedia.org/wiki/Opteron#Models
- jacques_chester 14y agoSlower per-core, certainly. But for some workloads more cores is worth it.
- reitzensteinm 14y agoI should have been more specific. They're so much slower per thread that they're still slower overall even in heavily multithreaded tasks. In this Anandtech review, the 16 core Opteron trades blows with a six core Xeon (clocked at 2.3ghz vs 2.66ghz): http://www.anandtech.com/show/5058/amds-opteron-interlagos-6200 http://www.anandtech.com/show/5058/amds-opteron-interlagos-6... The 8 core DP Xeons weren't out yet when that review took place, but the Sandy Bridge chip was a big improvement over Westmere, in addition to the extra cores.
- jacques_chester 14y agoI'm not sure it's such a slam dunk -- a brief scan of the virtual machine benchmark didn't seem to have a more heavily concurrent load. Plus the Opterons are substantially cheaper. If I was building a server I'd probably look at the Intel parts, the cost/performance curve is justifiable. But my personal case right now is running lots of test VMs simultaneously on a workstation, the Opterons are more attractive.
- reitzensteinm 14y agoI should probably have linked to Sandy Bridge EP vs Bulldozer, which is much more lopsided. The 6C holds its own nearly everywhere, with comparable price and much lower power usage, and there's always the option of bumping up to 8C when needed: http://www.anandtech.com/show/5553/the-xeon-e52600-dual-sandybridge-for-servers/2 http://www.anandtech.com/show/5553/the-xeon-e52600-dual-sand... This latest generation was not favourable for AMD. 16 core Interlagos in many cases barely outperforms the old 12 core Magny Cours.
- ktizo 14y agoI don't mean 12 core, I mean 32 core. AMD is selling 16 core CPUs. And the Mac Pro is not a dual CPU, 32 core, twin graphics card machine, which is what I described. here is one company selling them - http://www.titanuscomputers.com http://www.titanuscomputers.com I priced up a 32 core AMD machine with two 2GB Nvidia GTX 680 cards and it comes to just under $5000.
- tedunangst 14y agothanks.
- ktizo 14y agoNo hassles. Sorry if I came across a bit grouchy.
- cheatercheater 14y agoYou haven't.
- ktizo 14y agoThat's lucky.. I've been feeling pretty tired and grouchy.
