TechPowerUp came across rumors that NVIDIA is working on the GeForce GTX Titan II. This new card is reportedly based on the GM200, which will still be made on a 28nm process. The Maxwell based core is said to offer 3072 CUDA cores with 3MB L3 cache memory and a 384-bit GDDR5 memory bus with a whopping 12GB of memory!
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 4K Ultra HD, and perhaps even 5K 16xHD. The chip features reasonably high clock speeds, with the core running at 1100 MHz, and a staggering 1390 MHz GPU Boost. The memory, however, is clocked at 6.00 GHz.
