Intel to Ship 48-Core Microprocessors Later This Quarter to Developers

According to Intel, the 48-core chip operates at the clock-speed comparable to Intel Atom microprocessors, which means that the frequency of the microprocessors is in the range between 1.60GHz and 1.83GHz.

The SCC can run all 48 cores at one time over a range of 25W to 125W and selectively vary the voltage and frequency of the mesh network as well as sets of cores. Each tile (2 cores) can have its own frequency, and groupings of four tiles (8 cores) can each run at their own voltage.

So they've repositioned Larrabee from GPU to GPCPU?

Thats what it sounds like. But aren't most CPU's general purpose central processing units (GPCPU)?

On a side note, I hope you don't mind that I quoted you in my signature. I thought it was a funny quote, but I will remove it if it bothers you.

Just thinking about overclocking that gives me a headache!

This isn't Larrabee, but purely an experimental chip for developers. Think of it as a expanded "Terascale" chip Intel demonstrated few years ago. Larrabee test boards are supposed to be coming soon, but who knows if that plan changed.

Intel SCC(Single Chip Cloud Computer) specs

-45nm Hi-K Metal Gate process
-567mm2
-4x6 mesh tiles with each tile containing 2 P54C Pentium cores
-Each core has 256KB L2 cache
-125W @ 1GHz Core/Uncore and 2GHz Router

So we see Intel using P54C derivatives for ultra low power and many core products. Here's a summary.

Simple nothing added on P54C for research: SCC
Very wide 16x vector engine: Larrabee
General purpose code optimized: Atom
