GeForce GTX 980 vs Geforce GTX 690

Intro

The GeForce GTX 980 comes with a GPU clock speed of 1126 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 256-bit bus. It also features 2048 SPUs, 128 TAUs, and 64 ROPs.

Compare those specifications to the Geforce GTX 690, which makes use of a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 RAM works at a frequency of 1502 MHz on this model. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

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 information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

Well, Im still proud of my Dual GTX 690 two years later, like the HD7990 this babies are future-proof, definitely.
