In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 SLI are marginally better than the Nvidia GeForce GTX 660 MSI Hawk 2GB Edition.

The GTX 660 has a 275 MHz higher core clock speed than the GTX 560, but the GTX 560 has 32 more Texture Mapping Units than the GTX 660. As a result, the GTX 560 exhibits a 3.9 GTexel/s better Texture Fill Rate than the GTX 660. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 660 has a 275 MHz higher core clock speed than the GTX 560, but the GTX 560 has 40 more Render Output Units than the GTX 660. As a result, the GTX 560 exhibits a 25.8 GPixel/s better Pixel Fill Rate than the GTX 660. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 was released over a year more recently than the GTX 560, and so the GTX 660 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 560.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GeForce GTX 560 SLI and the GeForce GTX 660 MSI Hawk 2GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 560 has 112.1 GB/sec greater memory bandwidth than the GTX 660, which means that the memory performance of the GTX 560 is massively better than the GTX 660.

The GeForce GTX 560 SLI has 672 Shader Processing Units and the GeForce GTX 660 MSI Hawk 2GB Edition has 960. However, the actual shader performance of the GTX 560 is 1089 and the actual shader performance of the GTX 660 is 1104. The GTX 660 having 15 better shader performance is not particularly notable, as altogether the GTX 560 performs better when taking into account other relevant data.

The GTX 660 transistor size technology is 12 nm (nanometers) smaller than the GTX 560. This means that the GTX 660 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 560. While they exhibit similar graphical performance, the GTX 660 should consume less power than the GTX 560.

The GeForce GTX 560 SLI requires 300 Watts to run but there is no entry for the GeForce GTX 660 MSI Hawk 2GB Edition. We would recommend a PSU with at least 600 Watts for the GTX 560.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 560 SLI is a solution of two GeForce GTX 560 put together using NVIDIA's SLI Technology.

Architecture
The Fermi Architecture was first manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It consists of 2 GPUs Codenamed GF114-325-A1 which, together, offer 672 Shader Processing Units, 12 TMUs and 64 ROPs. The central unit runs at 810MHz.

Memory
Each GPU accesses a 1GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1002MHz.

Power Consumption
Power Consumption should not surpass 300W.

Performance
Benchmarks Indicate Performance Similar to a Single GeForce GTX 580.

System Suggestions
GeForce GTX 560 SLI is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
GeForce GTX 660 MSI Hawk 2GB Edition a special edition of GeForce GTX 660.
The new features include the Twin Frozr III Thermal Design cooling solution which, according to MSI, generates 20% more airflow than traditional fan design.
In terms of overclocking, the base-clock was increased from 980MHz to 1085MHz and the boost clock can now reach 1150MHz, instead of 1033MHz. The memory clock was left untouched.
The overclocking is therefore extreme and the performance boost is around 8% when compared to the standard GeForce GTX 660.
