GeForce GTX 660 Ti Game Requirement Analysis
GeForce GTX 660 Ti is a Performance Graphics Card based on the Kepler Architecture.
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU. GPU
It equips a GPU GK104-300-KD-A2 which has 7 Stream Multiprocessors activated and thus offers 1344 Shader Processing Units, 112 TMUs and 24 ROPs. The Central Unit is initially clocked at 915MHz and goes up to 980MHz, in Turbo Mode.
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 192-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1502MHz.
With a rated board TDP of 150W, it requires at least a 450W PSU with two available 6-pin connectors.
At 1920x1080, the best suited resolution for GeForce GTX 660 Ti, benchmarks indicate its performance is a little over the older GeForce GTX 580.
GeForce GTX 660 Ti is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
