Over the last few months both have been busy with new releases. Nvidia has its GeForce GTX 950 and GTX 980 Ti, while AMD put its first HBM-powered cards in the Radeon R9 Fury X, Fury and the super-small R9 Nano into the shops.

According to JPR, overall GPU shipments are up quarter-over-quarter – with AMD’s overall GPU shipments up 15.8 per cent. But before AMD fanboys get all excited by a surprise return to form from AMD, JPR said that that NVIDIA “had an exceptionally strong quarter”. Nvidia saw an uptick of 21.3 per cent.

The PC market as a whole increased by 7.5 per cent quarter-over-quarter but decreased 9 per cent year-over-year. Nivida’s discrete GPU shipments were up 26.3 per cent according to JPR, while AMD’s discrete GPUs spiked by 33 per cent.

AMD’s mobile GPU shipments for notebooks increased by 17 per cent, while NVIDIA had 14 per cent.

The outfit has been going through hell lately. Last month AMD ace CPU architect Jim Keller stepped away from the company after completing his work on Zen.

Rogers was one of AMD’s high-ranking technology and engineering corporate fellows, and been responsible for helping to develop the software ecosystem behind AMD’s heterogeneous computing products and the Heterogeneous System Architecture.

He was a public figure for AMD and active on the software development and evangelism side, frequently presenting the latest HSA tech and announcements for AMD at keynotes and conferences.

While he is not the only person working on the software side of HSA at AMD, Rogers’ role in its development is important. Rogers was a major contributor to the HSA Foundation, helping to initially found it in 2012. He served as the Foundation’s president until he left AMD.

It seems his defection was kept secret, and took place sometime this quarter and did not manage to leak.

According to his LinkedIn profile Phil Rogers is now Nvidia’s “Chief Software Architect – Compute Server” which is similar to what he was doing over at AMD. Nvidia is not a member of the HSA Foundation, but they are currently gearing up for the launch of the Pascal GPU family, which has some features that overlap well with Phil Rogers’ expertise.

Pascal’s NVLink CPU & GPU interconnect would allow tightly coupled heterogonous computing similar to what AMD has been working on. It makes a fair bit of sense for Nvidia to bring over a heterogeneous compute specialist makes a great deal of sense.

Rogers’ departure from AMD will have to be mentioned on the earnings call on the 15th. AMD’s Gregory Stoner will probably replace him. Stoner is AMD’s current Senior Director of Compute Solutions Technology and long-time Vice President of the HSA Foundation.

According to TweakTown Nvidia is apparently dotting the “I” and working out where to put in the semi-colons for its Pascal GPU using TSMC’s 16nm FinFet node. AMD rumored has been wining and dining its old chums at GlobalFoundries to use its 14nm process for its Greenland GPU.

Although these sound like different technologies the “14nm and 16nm”  is difference how you measure a transistor. The outcome of both 14 and 16 should be a fairly same sized transistor with similar power features. TSMC calls its process 16nm FinFet, while Samsung and GloFo insist on calling it 14nm FinFet.

The dark satanic rumor mill suggests that the Greenland GPU, which has new Arctic Islands family micro-architecture, will have HBM2 memory. There will be up to 32GB of memory available for enthusiast and professional users. Consumer-oriented cards will have eight to 16GB of HBM2 memory. It will also have a new ISA (instruction set architecture).

It makes sense, AMD moved to HBM with its Fury line this year. Nvidia is expected to follow suit in 2016 with cards offering up to 32GB HBM2 as well.

Both Nvidia and AMD are drawn to FinFET which offers 90 percent more density than 28nm. Both will boost the transistors on offer with their next-generation GPUs, with 17 to 18 billion transistors currently being rumored.
