NVIDIA to Launch GeForce GTX 960 in January

NVIDIA is reportedly preparing to launch its mid-range GeForce GTX 960 graphics card some time in January, 2015; according to a SweClockers report. The card could be launched in the sidelines of the 2015 International CES. The card will be based on the company's new GM206 silicon, and it won't be a cut-down GM204. Its only specifications doing rounds are the memory bus width of 128-bit, and standard memory amount of 2 GB. Out of the box, the card could offer performance comparable to a GeForce GTX 770, with much lower power draw, and a $200-ish price.

NVIDIA GeForce GTX 960 to Retain Memory Bus from GTX 970

Among other things like CUDA core and TMU counts, NVIDIA was expected to give its next mid-range graphics card, the GeForce GTX 960, a narrower memory bus, with 3 GB of memory, if not less. A sample sniffed out by India's overly transparent customs department, en route testing facilities in the country, reveal that it's not the case.

The GeForce GTX 960, according to description given in the shipping manifest of the sample, features 4 GB of memory, with a full 256-bit wide memory interface. It also reveals clock speeds to be in the neighborhood of 993 MHz core, with 6.00 GHz memory (GDDR5-effective). It doesn't, however, confirm that the GTX 960 is based on a cut-down GM204 silicon. This could still be different chip, the so-called GM206, which succeeds the GK106.

No 20 nm GPUs from AMD This Year

It's not just NVIDIA, which will lack 20 nm GPUs in its portfolio this year. AMD senior vice-president Lisa Su, responding to a question by Wells Fargo, in its Q1 investors call, confirmed that her company will stay on 28 nm throughout 2014, and it's only later that it will move on to 20 nm, and FinFET after that. "I think what I said earlier sort of what we're doing in terms of technology strategy, we are 28 this year, we have 20-nanometer in design, and then FinFET thereafter. So that's the overall product portfolio," she said.

AMD and NVIDIA manufacture their GPUs on a common foundry, TSMC, which has faced delays in implementing its 20 nanometer silicon fab node transition, forcing both companies to come up with new GPUs on existing 28 nm nodes. A huge leap in performance could be a tough ask for those new GPUs. NVIDIA is expected to tape out its performance-segment GM204 and mid-range GM206 chips, both of which are 28 nm, later this month, and the first GeForce GTX products based on the two are expected to roll out by late-Q4 2014 and early-Q1 2015, respectively.

NVIDIA GM204 and GM206 to Tape-Out in April, Products to Launch in Q4?

It looks like things are going horribly wrong at TSMC, NVIDIA and AMD's principal foundry partner, with its 20 nm manufacturing process, which is throwing a wrench into the works at NVIDIA, forcing it to re-engineer an entire lineup of "Maxwell" GPUs based on existing 28 nm process. Either that, or NVIDIA is confident of delivering an efficiency leap using Maxwell on existing/mature 28 nm process, and saving costs in the process. NVIDIA is probably drawing comfort from the excellent energy-efficiency demonstrated by its Maxwell-based GeForce GTX 750 series. According to a 3DCenter.org report, NVIDIA's next mainline GPUs, the GM204 and GM206, which will be built on the 28 nm process, and "Maxwell" architecture, will tape out later this month. Products based on the two, however, can't be expected before Q4 2014, as late as December, or even as late as January 2015.

GM204 succeeds GK104 as the company's next workhorse performance-segment silicon, which could power graphics card SKUs ranging all the way from US $250 to $500. An older report suggests that it could feature as many as 3,200 CUDA cores. The GM204 could be taped out in April 2014, and the first GeForce products based on it could launch no sooner than December 2014. The GM206 is the company's next mid-range silicon, which succeeds GK106. It will tape out in April, alongside the GM204, but products based on it will launch only in January 2015. The GM200 is a different beast altogether. There's no mention of which process the chip will be based on, but it will succeed the GK110, and should offer performance increments worthy of being a successor. For that, it has to be based on the 20 nm process. It will tape-out in June 2014, and products based on it will launch only in or after Q2 2015.Source: 3DCenter.org

GM107 Features 128 CUDA Cores Per Streaming Multiprocessor

NVIDIA's upcoming GM107 GPU, the first to be based on its next-generation "Maxwell" GPU architecture, reportedly features a different arrangement of CUDA cores and streaming multiprocessors to those typically associated with "Kepler," although the component hierarchy is similar. The chip reportedly features five streaming multiprocessors, highly integrated computation subunits of the GPU. NVIDIA is referring to these parts as "streaming multiprocessor (Maxwell)," or SMMs.

Further, each streaming multiprocessor features 128 CUDA cores, and not the 192 CUDA cores found in SMX units of "Kepler" GPUs. If true, GM107 features 640 CUDA cores, all of which will be enabled on the GeForce GTX 750 Ti. If NVIDIA is carving out the GTX 750 by disabling one of those streaming multiprocessors, its CUDA core count works out to be 512. NVIDIA will apparently build two GPUs on the existing 28 nm process, the GM107, and the smaller GM108; and three higher performing chips on the next-generation 20 nm process, the GM206, the GM204, and the GM200. The three, as you might have figured out, succeed the GK106, GK104, and GK110, respectively.
