1156 first chips to be i5-750 i7-860 & i7-870

[Greebo]

This roadmap shows the i7-920 being sold until Q3/2010. I thought everyone was expecting the 920 to be discontinued when the i5 launched?

Mmm confused....

PS.

On this public forum I especially like the Intel Confidential across the bottom of the slide

nvm

So by the time games fully use quad cores and start using 6cores we will have 8 and 12 cores already out

Yet I bet you'll need *insert_newest_GPU*x2 for it.

Funny how since c2d showed up, CPUs are so much more powerfull than the games need.

Coding games for multi-core is a very tricky business. Games are effectively a sequence of user driven events that are very difficult to break down into any kind of independent processes. At best, most designers have fobbed off large subsystems to different cores, such as sound engine, physics engine etc, providing some limited performance gains. Fragmenting those subsystems any more raises some big mutual exclusion and timing issues, each of which require some very time consuming and error prone designs. At worst, a bad design could leave you with cores waiting on other cores to finish stuff before they continue with their own instructions.

You could argue that multicore cpu's aren't really an ideal platform for games. Clock speed is still the performance driver atm. Until chip designers incorporate some kind of system whereby cpu level instructions can be automatically distributed amongst the available set of cores (thus abstracting the issue away from the programmer), I don't believe we'll see any huge benefit to games on multi-core platforms.

Then again, im sure games arn't intels GREATEST interest.


Not to mention that in just day to day stuff, there IS a noticable difference between a Single, dual and Quad core processor. (used pentium 4, D, C2D, Q9550, i7).

Which is partly why I'm looking at a big upgrade in the Autumn
