GeForce GTX 260 vs GeForce GTX 260 Core 216

Intro

The GeForce GTX 260 features a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also makes use of a 448-bit memory bus, and makes use of a 65 nm design. It is comprised of 192 SPUs, 64 TAUs, and 28 ROPs.

Compare those specs to the GeForce GTX 260 Core 216, which comes with a core clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit bus, and makes use of a 65 nm design. It features 216 SPUs, 72 Texture Address Units, and 28 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 260 182 Watts
GeForce GTX 260 Core 216 202 Watts
Difference: 20 Watts (11%)

Memory Bandwidth

Both cards have the exact same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce GTX 260 Core 216 is just a bit (about 13%) more effective at anisotropic filtering than the GeForce GTX 260. (explain)

GeForce GTX 260 Core 216 41472 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 4608 (13%)

Pixel Rate

Both cards have the exact same pixel rate, so theoretically they should be equally good at at AA, and be able to handle the same screen resolutions. (explain)

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 (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
