NVIDIA today unveiled the GeForce GTX 1080 Ti graphics card, its fastest consumer graphics card based on the “Pascal” GPU architecture, and which is positioned to be more affordable than the flagship TITAN X Pascal, at USD $699, with market availability from the first week of March, 2017. Based on the same “GP102” silicon as the TITAN X Pascal, the GTX 1080 Ti is slightly cut-down. While it features the same 3,584 CUDA cores as the TITAN X Pascal, the memory amount is now lower, at 11 GB, over a slightly narrower 352-bit with GDDR5X memory interface. This translates to 11 memory chips on the card. On the bright side, NVIDIA is using newer memory chips than the one it deployed on the TITAN X Pascal, which run at 11 GHz (GDDR5X-effective), so the memory bandwidth is 484 GB/s.
Besides the narrower 352-bit memory bus, the ROP count is lowered to 88 (from 96 on the TITAN X Pascal), while the TMU count is unchanged from 224. The GPU core is clocked at a boost frequency of up to 1.60 GHz, with the ability to overclock beyond the 2.00 GHz mark. It gets better: the GTX 1080 Ti features certain memory advancements not found on other “Pascal” based graphics cards: a newer memory chip and optimized memory interface, that’s running at 11 Gbps. NVIDIA’s Tiled Rendering Technology has also been finally announced publicly; a feature NVIDIA has been hiding from its consumers since the GeForce “Maxwell” architecture, it is one of the secret sauces that enable NVIDIA’s lead.
The Tiled Rendering technology brings about huge improvements in memory bandwidth utilization by optimizing the render process to work in square sized chunks, instead of drawing the whole polygon. Thus, geometry and textures of a processed object stays on-chip (in the L2 cache), which reduces cache misses and memory bandwidth requirements.
