|possible picture of the new chip|
There are evidence to what is comming. The GM200 silicon will be built on the existing 28 nm or even the 20nm silicon fab process if there are delays. Among other SKUs, NVIDIA's next GeForce GTX TITAN product, the GTX TITAN II, could be based on this chip. We might all ready look at it this year.
A curious-looking data entry was submitted from an anonymous source to SiSoft's hardware database, which gives away some rather glaring details of the GM200.
To begin with, the GM200 will be built on the existing 28 nm node, and will feature a die-area of 551 mm². The chip will be based on the "Maxwell" architecture, and feature 3,072 CUDA cores, cushioned by a 3 MB L3 cache. The chip will likely feature a 384-bit wide GDDR5 memory interface, with lossless texture compression algorithms, which work to step up memory bandwidth. The standard memory amount is a staggering 12 GB, double that of the first-generation GTX TITAN. Given how AMD recently gave 8 GB variants of its Radeon R9 290X a coordinated launch, GPU vendors could be seeing a utility in giving their products such massive amounts of video memory, to cope with resolutions such as 5K 16xHD. The chip features reasonably high clock speeds, with the core running at 1100 MHz (normal), and a staggering 1.390+ MHz GPU Boost. The memory, however, is clocked at 6.00 GHz. In terms of CUDA cores we might see a serious increase, the Titan black has 2880 and we hope for 5760, but realisticly 5000 CUDA cores are far more likely to happen.
Now this could also just be a base model to test heat and endurance factors, it might be ramped up even more to compete with AMD´s Ati which makes some serious highend cards.
Stay tuned for more updates as we come closer to some concrete facts from Nvida themselves.
