Following the launch of a couple of more GK104-based SKUs, namely GeForce GTX 670 Ti, and GeForce GTX 670, some time in May; NVIDIA will launch its third (after GK104 and GK107) Kepler architecture-based silicon, codenamed GK106. GK106 will make up sub-$200 SKUs, and succeeds the GF116, on which SKUs such as the GeForce GTX 550 Ti, are based. The GK106 will make up at least one known desktop SKU, called GeForce GTX 660.

Its specifications are listed below.

• 28 nm, around 210 mm² die-area, Kepler architecture
• Two Graphics Processing Clusters (GPCs), four Streaming Multiprocessors (SMXs)
• 768 CUDA cores
• 64 TMUs, 24 ROPs
• 192-bit wide GDDR5 memory interface, holding 1.5 GB or 2 GB memory
• PCI-Express 3.0 bus interface
• Around 130W TDP
• Speculated performance comparable to GTX 560 Ti and HD 6950, competitive to Radeon HD 7800 series
