GeForce GTX 570 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 570 has a core clock speed of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also features a 320-bit memory bus, and uses a 40 nm design. It features 480 SPUs, 60 Texture Address Units, and 40 ROPs.

Compare that to the GeForce GTX 660 Ti, which features core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 should be 6% quicker than the GeForce GTX 660 Ti in general, because of its higher 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 should be much (more or less 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 using high levels of AA is important to you, then the GeForce GTX 570 is the winner, and very much so. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum 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
