GeForce GTX 460 (OEM) vs GeForce GTX 465

Intro

The GeForce GTX 460 (OEM) uses a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 memory runs at a speed of 850 MHz on this specific model. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

Compare all that to the GeForce GTX 465, which features a clock frequency of 607 MHz and a GDDR5 memory speed of 802 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It features 352 SPUs, 44 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 (OEM) 150 Watts
GeForce GTX 465 200 Watts
Difference: 50 Watts (33%)

Memory Bandwidth

In theory, the GeForce GTX 460 (OEM) is 6% quicker than the GeForce GTX 465 in general, because of its higher bandwidth. (explain)

GeForce GTX 460 (OEM) 108800 MB/sec
GeForce GTX 465 102592 MB/sec
Difference: 6208 (6%)

Texel Rate

The GeForce GTX 460 (OEM) will be quite a bit (approximately 36%) more effective at AF than the GeForce GTX 465. (explain)

GeForce GTX 460 (OEM) 36400 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 9692 (36%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 (OEM) is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 460 (OEM) 20800 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 1376 (7%)

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 (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are applied in one second. This is worked out by multiplying the total amount of texture units 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
