Including the upcoming NVIDIA GeForce GTX 960 graphics card, till now from Maxwell architecture, NVIDIA has out three cores GM204, GM107 and GM206, but they all are small cores from NVIDIA Maxwell family featuring 256-bit memory interface at peak. According to Kepler’s example, NVIDIA also has a big heart GM200 GPU core and most probably it will be applied first in the super flagship NVIDIA GeForce GTX Titan II or NVIDIA GeForce GTX Titan X. The GM200 core pictures have also leaked in the wild and from below picture you can see that the GPU included 12 Hynix GDDR5 memory chips with a capacity of 8 GB (1 GB) and 32-bit bus, and therefore Graphics Card has at its 12GB of VRAM GDDR5 384-bit interface. The price would be raised to $1,349.
NVIDIA GeForce GTX Titan X: Maxwell GM200 Core, 12Gb of VRAM priced at $1,349
In Kepler era, NVIDIA GK110 was the first large core chip in the market for professional card and then also for the consumer market, GM200 in general as well. Currently, specifications of GM200 core are not clear, but the message is displayed before the exposure GM200 core will have 3072 CUDA core, 384bit memory interface, with 12GB GDDR5 memory.
This card may be officially named NVIDIA GeForce GTX Titan X, before there was also news that on Idle-Mode the fans stop in order to reduce the noise also will be lower lower TDP.
GM200 core based NVIDIA GeForce GTX Titan X graphics card specification will undoubtedly elevate to a new level, but I am afraid there consequent soaring prices, 12GB memory will increase costs, but even more critical is that from the AMD side they have not any new product in their portfolio and NVIDIA from the bucket the high-end market has been captured by GTX 980/970. If they reduce Titan X price to $999 then with 12GB of VRAM it will sell like a hot cake.
Most finally, a domestic forum recently also exposed 3DMark11 score of R9 390X, obtained 8121 points. The current single-core High-End Graphics card from AMD camp R9 290X obtained 4611 points and on the other side GTX 980 scored 5735 points. So the counted performance of R9 390X in comparison with the current Single-core High-End Graphics card boost upto 50%. Really too exaggerated, may be HBM memory is the reason behind such massive results.
