The new Xeons won't be broadly available until the first half of 2012, but Intel has been shipping the new chips to a small number of cloud and HPC customers since September. The new E5 family is based on the same core as the Core i7-3960X Intel launched yesterday. The E5, while important to Intel's overall server lineup, isn't as interesting as the public debut of Knights Corner. Recall that Intel's canceled GPU (codenamed Larrabee) found new life as the prototype device for future HPC accelerators and complementary products. According to Intel, Knights Corner packs 50 x86 processor cores into a single die built on 22nm technology. The chip is capable of delivering up to 1TFlop of sustained performance in double-precision floating point code and operates at 1 — 1.2GHz. NVIDIA's current high-end M2090 Tesla GPU, in contrast, is capable of just 665 DP GFlops."
