GeForce GTX 260 Core 216 vs GeForce GTX 465

Intro

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

Compare that to the GeForce GTX 465, which uses a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 memory is set to run at a speed of 802 MHz on this specific model. It features 352 SPUs as well as 44 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 465 102592 MB/sec
Difference: 9296 (9%)

Texel Rate

The GeForce GTX 260 Core 216 should be a lot (approximately 55%) better at AF than the GeForce GTX 465. (explain)

GeForce GTX 260 Core 216 41472 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 14764 (55%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 465 is the winner, though only just barely. (explain)

GeForce GTX 465 19424 Mpixels/sec
GeForce GTX 260 Core 216 16128 Mpixels/sec
Difference: 3296 (20%)

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 max amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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