Intel Xeon Phi to get Serious Refresh in 2015?

Intel was testing the waters with their Xeon Phi co-processor. Based on the architecture designed for the original Pentium processors, it was released in six products ranging from 57 to 61 cores and 6 to 16GB of RAM. This lead to double precision performance of between 1 and 1.2 TFLOPs. It was fabricated using their 22nm tri-gate technology. All of this was under the Knights Corner initiative.

In 2015, Intel plans to have Knights Landing ready for consumption. A modified Silvermont architecture will replace the many simple (basically 15 year-old) cores of the previous generation; up to 72 Silvermont-based cores (each with 4 threads) in fact. It will introduce the AVX-512 instruction set. AVX-512 allows applications to vectorize 8 64-bit (double-precision float or long integer) or 16 32-bit (single-precision float or standard integer) values.

In other words, packing a bunch of related problems into a single instruction.

The most interesting part? Two versions will be offered: Add-In Boards (AIBs) and a standalone CPU. It will not require a host CPU, because of its x86 heritage, if your application is entirely suited for an MIC architecture; unlike a Tesla, it is bootable with existing and common OSes. It can also be paired with standard Xeon processors if you would like a few strong threads with the 288 (72 x 4) the Xeon Phi provides.

And, while I doubt Intel would want to cut anyone else in, VR-Zone notes that this opens the door for AIB partners to make non-reference cards and manage some level of customer support. I'll believe a non-Intel branded AIB only when I see it.

I want to see Windows Task Manager try to show a 4P board full of these.

Windows 8 Task Manager can handle that pretty well.

How much will this Xeon Phi version cost, and compare it to the Cost/performence/gigaflops of the AMD and Nvidia offerings! I could see the Xeon phi being of some use for Blender rendering, short of AMD and Nvidia getting their hardware driver support for Blender cycles render ducks in order! I would love to see a low cost ARM 64 variant to the Xeon Phi, but the Phi is going to be a ray tracing monster, with monster a size price. So AVX 512 bit is the new highend, how many others offer AVX 512 bit? Scott have you tried the Epiphany-IV 64-core 28nm Microprocessor, I would love to see a review of this low cost, low power multicore processor for rendering.
