Intel To Demo Octo-Core CPU


Intel To Demo Octo-Core CPU

We knew when Intel launched its quad-core Nehalem line-up that it had plans to pack even more cores into a single die and come the next IEEE International Solid-State Circuits Conference (IISSCC) we'll get to see just that. Intel will be taking the opportunity to show off Octo-Core Xeon processors.

Being built on the Nehalem architecture, these CPUs benefit, unsurprisingly, not only from eight cores but the ability to execute two simultaneous threads on each - or 16 over the entire CPU. In a dual-socket solution, that would give a near-ridiculous 16 cores running an actually-ridiculous 32 concurrent threads.

The number of situation in which that kind of number crunching power would ever be needed are understandably limited. Although the potential power, and thus money, saving potential of consolidating a server array into one PC will no doubt be of much appeal.

Real-time ray tracing here we come!

Well, most applications nowadays are making support for multi-core, including games, video encoding etc. Even the OS can eat threads like no tommorow. Having 32 threads doing a H264 encode would be very nice.

meh, and we all though the numbers war was over when the GHz battles ended with the P4...

Personally I won't be content until Intel offers a 76.3 core chip.

I think that pretty soon we're going to see languages and frameworks that allow programmers to make multi-threaded programmes without really needing to think about it - at which point it will be a case of the more threads the better. For instance, locating an object in a list or sorting a list could both be done in a multi-threaded manner transparently to the programmer, I'd have thought.

Quite apart from that, it's easy to imagine a case where a game programmer assigns a thread to each AI characters decision making, for instance, so you could easily have 20 or 30 concurrent threads going.

the other application is vm farms, you should be able to get more vm's per server/blade.

So let's have a sweepstakes on what they'll call this (eventual) hi-end technology, Core i8?
