NVIDIA GeForce GTX 1660 Ti Mobile

6 GB GDDR6 · 192-bit · 1,536 cores

Top of NVIDIA's mobile GTX 16 line and the fastest NVIDIA laptop GPU without RT cores, built on the full TU116 die. Max-Q designs of the same part run at noticeably lower clocks and board power for thin chassis. With no RT or Tensor cores, hardware ray tracing and DLSS are unavailable.

Notes
No Tensor Cores and no RT Cores on TU116/TU117. Dedicated FP16 units give full 2x FP16 throughput; INT8 via DP4A (CUDA compute capability 7.5). FP64 at 1/32. DXR ray tracing runs on shader cores only, with no hardware acceleration. No BF16, TF32, FP8 or DLSS.
