GeForce GTX 750 Ti vs Geforce GTX 690

Intro

The GeForce GTX 750 Ti has a clock speed of 1020 MHz and a GDDR5 memory frequency of 1350 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the Geforce GTX 690, which features GPU core speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 128 Texture Address Units, and 32 ROPs.

The Geforce GTX 690 is a lot (approximately 474%) more effective at AF than the GeForce GTX 750 Ti. (explain)

Geforce GTX 690 234240 Mtexels/sec
GeForce GTX 750 Ti 40800 Mtexels/sec
Difference: 193440 (474%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 690 is the winner, by far. (explain)

Geforce GTX 690 58560 Mpixels/sec
GeForce GTX 750 Ti 16320 Mpixels/sec
Difference: 42240 (259%)

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: Bandwidth is the max amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better 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 the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
