IDF FALL 07: Pat Gelsinger delivered a few more tidbits of information on Nehalem. SMP is already up and running with QuickPath technology.

I want one

16 CORES! What the! How come it invented! I Don't know why some one need 16 Cores, maybe to lunch some rockets ! I like it.

ssj12 · 19th Sep 2007, 20:07

its 8 cores and 16 threads not 16 cores, that would be 32 threads.

Do we even have an OS that can utilise all 16 threads? If not, it sounds like intel are just trying to show off their e-peen...

As far as i know, OS's don't have problems handing masses of CPU's and lots of threads

the problem is getting programs that can utilise it

You can manually assign programs to different cores/threads

windows will automatically spread the load over cores so there's not a lot of point, all my background processes probably use 1% of a core, Games use 100% of a core

So in total i can use 101% of a 200% processor, or 101% of a 400% processor, or 101% of a 800% processor
Even sup comm will run fine on dual core, because that's all it can really utilise

So i don't see the point in >2 cores ATM, and quad core at the max, until there are a lot of good multi cored programs, adding all these extra cores is just a waste of money
Its a shame AMD never did get that fusion thing going, it would be awesome for the next ... well i don't know how long tbh, but certainly many years to come

There are many game engines that are being updated to utilise multicore systems. Next year ''threading your software'' will be the thing to be doing and by the time nehalem comes out then there will be plenty of stuff that makes use of all those cores/threads. Something as powerful as that 16 thread system is probably going to be a video editing or rendering application anyway, most of those will already ramp up to fill those threads.
I don't see why people moan about a game not maxing out all their cores. I doubt there is a game out at the moment that maxes out a single core on even the cheapest C2D system whilst you play the game at proper resolutions above 1024x768. The game that does go over to another core isn't going to be doing it for the sake of it... the other cores will be for parallel tasks like physics and audio. Otherwise, what's the point.

Now they have the cores to play with, they will start playing with them. Bring back functional programming

we have had consumer multi-core for at least a year or 2, Servers have had SMP for as long as i can remember
And then there was hyper threading as well

Its taken a long time for any kind of multi-threading to come out of the pipework, and so far none of it exactly blows your socks off

One of the new optimisations will allow for 256 simultaneous compares in one instruction.

That SSE4 looks nifty. Also, with Quick Path, they should catch up with AMD on multi-proc performance. AMD really needs to start innovating like Intel is right now.

wuyanxu · 24th Sep 2007, 10:03

quick question: would i need SSE4 if i were just to play games?

anyone think 4 cures are enough for any games for at least 3 to 4 years?
