GeForce GTX 260 Core 216 vs GeForce GTX 660

Intro

The GeForce GTX 260 Core 216 makes use of a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory is set to run at a speed of 999 MHz on this particular model. It features 216 SPUs along with 72 TAUs and 28 ROPs.

Compare those specifications to the GeForce GTX 660, which comes with a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 192-bit memory bus, and makes use of a 28 nm design. It is made up of 960 SPUs, 80 Texture Address Units, and 24 ROPs.

GeForce GTX 260 Core 216 111888 MB/sec
Difference: 32304 (29%)

Texel Rate

The GeForce GTX 660 should be quite a bit (approximately 89%) more effective at anisotropic filtering than the GeForce GTX 260 Core 216. (explain)

GeForce GTX 660 78400 Mtexels/sec
GeForce GTX 260 Core 216 41472 Mtexels/sec
Difference: 36928 (89%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 660 is superior to the GeForce GTX 260 Core 216, by a large margin. (explain)

GeForce GTX 660 23520 Mpixels/sec
GeForce GTX 260 Core 216 16128 Mpixels/sec
Difference: 7392 (46%)

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 (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
