GeForce GTX 570 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 570 features core speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 RAM. It features 480 SPUs along with 60 Texture Address Units and 40 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 660 Ti, which has a core clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 192-bit memory bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 TAUs, and 24 ROPs.

GeForce GTX 660 Ti 150 Watts
GeForce GTX 570 219 Watts
Difference: 69 Watts (46%)

Memory Bandwidth

In theory, the GeForce GTX 570 is 6% faster than the GeForce GTX 660 Ti overall, because of its greater data rate. (explain)

GeForce GTX 570 152000 MB/sec
GeForce GTX 660 Ti 144000 MB/sec
Difference: 8000 (6%)

Texel Rate

The GeForce GTX 660 Ti is quite a bit (about 133%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)

GeForce GTX 660 Ti 102480 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 58560 (133%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 570 is the winner, by a large margin. (explain)

GeForce GTX 570 29280 Mpixels/sec
GeForce GTX 660 Ti 21960 Mpixels/sec
Difference: 7320 (33%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

[...] GeForce GTX 570 vs GeForce GTX 660 Ti – Performance Comparison Benchmarks @ Hardware Compare better AA support for 570,more memory bandwith,an OC 660ti will get you the same,or a little more power ,why wasting your money in a quite similar stuff? [...]

Guys, Im do 3D Rendering with CUDA GPGPU. I heard that GTX6** are bad for computing. I use mostly Blender Cycles or OctaneRender. I do play latest games too.How bad is the GTX660 vs GTX570. Please anyone. I have to buy either of the two
