GeForce GTX 260 Core 216 vs GeForce GTX 465

Intro

The GeForce GTX 260 Core 216 uses a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this particular card. It features 216 SPUs along with 72 Texture Address Units and 28 Rasterization Operator Units.

Compare that to the GeForce GTX 465, which comes with core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs as well as 44 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 465 200 Watts
GeForce GTX 260 Core 216 202 Watts
Difference: 2 Watts (1%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 Core 216 will be 9% quicker than the GeForce GTX 465 in general, because of its higher data rate. (explain)

GeForce GTX 260 Core 216 111888 MB/sec
GeForce GTX 465 102592 MB/sec
Difference: 9296 (9%)

Texel Rate

The GeForce GTX 260 Core 216 should be quite a bit (about 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

The GeForce GTX 465 is a small bit (about 20%) faster with regards to anti-aliasing than the GeForce GTX 260 Core 216, and also will be capable of handling higher screen resolutions better. (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 data (measured in megabytes per second) that can be moved 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 type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
