GeForce GTX 260 216SP 55 nm vs GeForce GTX 260 Core 216

Intro

The GeForce GTX 260 216SP 55 nm has core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 216 SPUs as well as 72 TAUs and 28 Rasterization Operator Units.

Compare all that to the GeForce GTX 260 Core 216, which makes use of a 65 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 RAM is set to run at a speed of 999 MHz on this card. It features 216 SPUs along with 72 Texture Address Units and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 260 216SP 55 nm 171 Watts
GeForce GTX 260 Core 216 202 Watts
Difference: 31 Watts (18%)

Memory Bandwidth

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

Texel Rate

Both cards have the exact same texel rate, so theoretically they should be equally good at at AF. (explain)

Pixel Rate

Both cards have the exact same pixel fill rate, so in theory they should be equally good at at AA, and be capable of handling 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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
