Intel Corp.’s co-processor products based on MIC [many integrated cores] architecture clearly have huge importance for the company since they are aimed at the most demanding and rapidly evolving market of high-performance computing. Regrettably, Intel is very tight-lipped about the future of its Xeon Phi-branded products as well as about its performance targets. This does not mean that Intel does not have clear plans.

According to a slide from an Intel presentation that leaked to the web (1, 2, 3), Intel Xeon Phi code-named Knights Landing will be released sometimes in late 2014 or in 2015. The chip, which will be made using 14nm process technology, will come in either PCIe co-processor card or CPU form-factor. The KNL co-processor will support new AVX 3.1 instructions, built-in DDR4 memory controller, on-package high-speed memory and a number of other innovations.

The most important aspect about the Xeon Phi “Knights Landing” product is its performance, which is expected to be around or over double precision 3TFLOPS, or 14 – 16GFLOPS/w; up significantly from ~1TFLOPS per current Knights Corner chip (4 – 6GFLOPS/w). Keeping in mind that Knights Landing is 1.5 – 2 years away, three times performance increase seem significant and enough to compete against its rivals. For example, Nvidia Corp.’s Kepler has 5.7GFLOPS/w DP performance, whereas its next-gen Maxwell (competitor for KNL) will offer something between 8GFLOPS/w and 16GFLOPS/w.

Code-named “Knights Landing”, the next generation of Intel MIC architecture-based products will be available as a coprocessor or a host processor (CPU) and manufactured using Intel's 14nm process technology featuring second generation tri-gate transistors.

As a PCIe card-based coprocessor, "Knights Landing" will handle offload workloads from the system's Intel Xeon processors and provide an upgrade path for users of current generation of coprocessors, much like it does today. However, as a host processor directly installed in the motherboard socket, it will function as a CPU and enable the next leap in compute density and performance per watt, handling all the duties of the primary processor and the specialized coprocessor at the same time. When used as a CPU, "Knights Landing" will also remove programming complexities of data transfer over PCIe, common in accelerators today.

intel products always looks good on paper remember ivy-bridge.
Future is FUSION-
AMD FirePro™ S10000(28nm 2D) delivers up to 5.91 TFLOPS of peak single precision and 1.48 TFLOPs of peak double precision floating point performance, compared to Nvidia Tesla K10 that is capable of up to 4.58 TFLOPS of peak single precision and 190 GFLOPs double precision peak floating point performance and even better than latest k20x(28nm 2D) and xeon-phi(22nm 3D) in double precision performance the best thing with s10000 is unified design.
AMD can do even better than xeon-phi with ARMv8 modified cores so lower TDP, lesser die size(one of the the most important to get denser server)
i m sure intel will use 3D memory stacking to achieve that performance in lower TDP, at that time AMD will also have access to 14nm-XM and for 3D memory AMD had that running successfully since 2011 in labs.

actually this all is waste coz of AMD hetrogenous APU/SoC. Scientists said with help of HSA APU/SoC it's possible to make petascale supercomputer in 1/3rd of power consumption which is beyond reach of xeon-phi and tesla or Fire-pro .

25 GFLOPS/W in 2013? Yeah, right.

15Gflops/w and for 3TFlops - it is approximately 200W. Wow. This is going to be really hot and power hungry

Really? The k20x does only 1.32TFlop at 235W, and that's already the most energy efficient computational tool out there. 3Tflop for 200W means Phi is 2.5x more energy efficient!

Lets see what AMD/Nvidia can come up with till 2015, but I like how Intel is trying to put on pressure

LMAO, so Knights Corner (available at stores today) won't actually support its performance rating of 1 DP TFLOPS until 2014? The 22nm process tech, the GDDR5 memory interface and the PCIe3 form factor and bus are available today, but the product won't actually come with - so to speak - teraflops until next year? Features and performance figures are given in two different colums for space reasons, not because they arrive in different time frames. Notice how Knights Corner and Knights Landing occupy two years in the diagram because the same release stretches two years whereas for the CPUs a new either tick or tock is released each year.

Looks like you don't know how to read a graph!
