The GPU Specifications

Turing TU116 GPU Specifications

The GPU TU116 for the GeForce GTX 1660 (Ti) contains 6.6 billion transistors localized on the die. In comparison, Pascal had close to 12 billion transistors on a die size of 471mm2. Gamers will immediately look at the shader processors; the Quadro RTX 8000 has 4608 of them enabled and since everything with bits is in multitudes of eight and while looking at the GPU die photos; it has 24 SMs (streaming multiprocessors) each holding 64 cores = 1536 Shader processors. This GPU is fabbed on an optimized 12nm TSMC FinFET+ node and the full GPU is unlocked.

Graphics memory - GDDR6

Allow me to quickly inject a paragraph here. Another difference in-between Volta and Turing is graphics memory. HBM2 is a bust for consumer products, at least it seems and feels that way. The graphics industry at this time is clearly favoring the new GDDR6. It’s easier and cheaper to fab and add, and at this time can even exceed HBM2 in performance. The previous GeForce GTX 1080 with the latest GDDR5X memory could run 11 Gbps, often tweakable towards the 12 Gbps range. GDDR6 graphics memory will be faster and more energy efficient. The memory is advancing on GDDR5X (Graphics Double Data Rate (DDR)) but with a memory bandwidth of 14 Gbit/s it offers almost twice as much as GDDR5 (not GDDR5X) offers. In the near future, GDDR6 could transfer data at 16Gbps (bits per second), which is twice as fast as regular GDDR5. The GeForce GTX 1660 Ti (6GB 192-bit) will be paired with 12 Gbps GDDR6.
