Intel Launches 72-Core Knight's Landing Xeon Phi Supercomputer Chip (hothardware.com)
MojoKid writes: Intel announced a new version of their Xeon Phi line-up today, otherwise known as Knight's Landing. Whatever you want to call it, the pre-production chip is a 72-core coprocessor solution manufactured on a 14nm process with 3D Tri-Gate transistors. The family of coprocessors is built around Intel's MIC (Many Integrated Core) architecture which itself is part of a larger PCI-E add-in card solution for supercomputing applications. Knight's Landing succeeds the current version of Xeon Phi, codenamed Knight's Corner, which has up to 61 cores. The new Knight's Landing chip ups the ante with double-precision performance exceeding 3 teraflops and over 8 teraflops of single-precision performance. It also has 16GB of on-package MCDRAM memory, which Intel says is five times more power efficient as GDDR5 and three times as dense.
Better article.
Also summery is wrong: its on the 14nm process (the previous gen one was 22).
Really the memory looks like the only interesting thing here.
Kind of. The advantages of RISC faded pretty fast. The footprint of a decoder between something like x86 and say, ARM is really not that much, and a decoder is just a small part of a core these days. Clock speed is an issue of thermal footprint. So, all the disadvantages of the x86 (and it's x64 extensions) faded in the face of Intel's focus on process improvements. In the end, not even the Itanium could eek out enough of a win to dethrone the x86 architecture.
