NVIDIA is using 12 Gbps GDDR6 memory, which belts out 288 GB/s of bandwidth. It's endowed with 1,536 "Turing" CUDA cores, 96 TMUs, 48 ROPs, and a 192-bit wide memory interface, but the memory is 50% faster. The GeForce GTX 1660 Ti is the largest implementation of the TU116 and is being offered at US$279, which is about $60 higher than what the GTX 1060 6 GB "Pascal" is being sold at. The largest such GTX Turing chip is the new "TU116." The remaining CUDA cores are very much from the "Turing" architecture and benefit from the increased IPC and higher clock-speed headroom obtained with the switch to 12 nm. Interestingly, NVIDIA also decided to axe tensor cores, specialized hardware that accelerate deep-learning neural net building and training, shedding even more transistor load. With RTX out of the way, NVIDIA could physically remove RT cores that add billions of transistors to the silicon, making the chips smaller. The easiest way out of this problem for NVIDIA would be to not bother with RTX below the $350-mark and instead focus on making the GPU as cost-efficient as possible. In games without raytracing, the RTX 2060 has enough muscle for 1440p resolution, but on games with RTX-enabled, playability swings halfway between 1080p and 1440p. The RTX 2060 appears to be positioned on that limit. NVIDIA probably figured that getting RTX to work even at 1080p requires a minimum number of RT cores and CUDA core horsepower, which cannot be scaled down beyond a certain point because enabling RTX features already exacts a roughly 30 percent performance tax, and NVIDIA wouldn't want $200–$300 graphics cards being unable to play RTX-enabled games at 1080p at acceptable frame rates. ![]() What sets the two apart is right in the name-RTX real-time raytracing technology. The best part? Both are based on NVIDIA's latest 12 nm "Turing" architecture. ![]() The RTX 20-series starts at the $350-mark with the RTX 2060, while models below it are relegated to the GTX brand. NVIDIA today released the GeForce GTX 1660 Ti and with it splits its client-segment discrete graphics lineup into the GeForce GTX series and GeForce RTX series.
