Although many Nvidia AIC partners will have their own versions with higher GPU clock, the reference GTX 1660 works at 1530MHz GPU base and 1785MHz GPU Boost clock, while the memory is usually clocked at 8Gbps (2000MHz). The memory itself is now 6GB GDDR5 instead of 6GB GDDR6. There isn't any support for real-time ray tracing in the GTX 1660, but that's okay because it more than makes up for that missing feature in its price. There are 1,408 CUDA cores, 6GB of GDDR5 memory for a combined memory bandwidth of 192GB/Sec and a boost clock of nearly 1.8GHz, plus overclocking potential.
Both cards have a TDP of 120W and can be powered from a single 8-pin connector. The GTX 1660 6GB is likely to offer plenty of performance per buck/euro or pound in the mid-range market, and it looks like a great graphics card for gaming at 1080p resolution. The barrier has now been lowered further with the unveiling of GeForce GTX 1660 graphics cards. Nvidia has given the GTX 1660 an MSRP of US$219, and Newegg now has boards from ZOTAC, Gigabyte, MSI, and EVGA selling for US$219.99.
Subjected to a battery of compatibility tests with TUF Gaming motherboards, as well as a 144-hour validation program involving a variety of in-game and synthetic benchmarking, the TUF Gaming GeForce GTX 1660 targets gamers that prefer a longer upgrade cycle.
