GeForce GTX 660 Review

Overview
GeForce GTX 660 is a Performance Graphics Card based on the Kepler Architecture.


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 GK106-400-A1 which has 5 Stream Multiprocessors activated and thus offers 960 Shader Processing Units, 80 TMUs and 24 ROPs. The Central Unit is initially clocked at 980MHz and goes up to 1033MHz, in Turbo Mode.


Memory
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.


Power Consumption
With a rated board TDP of 140W, it requires at least a 450W PSU with one available 6-pin connector.


Performance
GeForce GTX 660 competes with Radeon HD 7850.
At 1920x1080, the best suited resolution for GeForce GTX 660, benchmarks indicate its performance is a little over the older GeForce GTX 570 and quite superior to Radeon HD 7850.


System Suggestions
GeForce GTX 660 is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.

Uh, why isn't there any information about the 3D Vision? According to the NVidia website, this card supports it.

Yeah, but not a big bottleneck. I'd recommend to buy a new GPU like R7 265 or GTX 750 TI (at least with 2GB of video ram)

Man,@BEJR2000, I think there is drop in rating as Nvidia 900 series got released[gtx 970 and gtx 980].

Man@BEJR2000 What do you mean by saying no? Do you mean to say Gtx 660's dropped rating has nothing to do with arrival and release of Nvidia's 900 series?

well i agree with a 8/9 as there are many new resolutions try to use this videocard higher than 2560x1440 not anything can be played at high so immagine what the lag will be on even higher resolutions ;)
