NVIDIA GeForce GTX 1660
Turing without RT or Tensor cores and with GDDR5 instead of GDDR6: 1,408 CUDA cores at up to 1,785MHz for $219. It undercut the 1660 Ti by $60 while giving up 128 shading units and a third of the memory bandwidth (192GB/s vs 288GB/s).
Pros
- 1,408 CUDA cores with a 1,785MHz boost clock for $219
- Single 8-pin connector keeps the 120W board simple to power
- Turing's NVENC encoder over Pascal-generation cards
- $60 cheaper than the GTX 1660 Ti at launch
Cons
- GDDR5 memory caps bandwidth at 192GB/s, well below the 1660 Ti's 288GB/s
- No RT cores, so no hardware ray tracing
- No Tensor cores, so no DLSS support
- 6GB of VRAM restricts texture settings at higher resolutions
