GeForce GTX 970 vs Geforce GTX 690

Intro

The GeForce GTX 970 has clock speeds of 1050 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1664 SPUs along with 104 TAUs and 64 Rasterization Operator Units.

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 970 is the winner, but not by far. (explain)

GeForce GTX 970 67200 Mpixels/sec
Geforce GTX 690 58560 Mpixels/sec
Difference: 8640 (15%)

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 max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's 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 memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the 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 the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
