GeForce GTX 460 SE vs Geforce GTX 690

Intro

The GeForce GTX 460 SE has clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 288 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.

Compare that to the Geforce GTX 690, which features a core clock speed of 915 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It features 1536 SPUs, 128 TAUs, and 32 ROPs.

Pixel Rate

The Geforce GTX 690 is much (about 182%) more effective at full screen anti-aliasing than the GeForce GTX 460 SE, and should be able to handle higher screen resolutions while still performing well. (explain)

Geforce GTX 690 58560 Mpixels/sec
GeForce GTX 460 SE 20800 Mpixels/sec
Difference: 37760 (182%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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