GeForce GTX 580 3GB vs GeForce GTX 970

Intro

The GeForce GTX 580 3GB comes with a GPU clock speed of 772 MHz, and the 3072 MB of GDDR5 RAM runs at 1002 MHz through a 384-bit bus. It also is comprised of 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Compare all that to the GeForce GTX 970, which makes use of a 28 nm design. nVidia has set the core speed at 1050 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular card. It features 1664 SPUs along with 104 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970 145 Watts
GeForce GTX 580 3GB 244 Watts
Difference: 99 Watts (68%)

Memory Bandwidth

In theory, the GeForce GTX 970 is 16% faster than the GeForce GTX 580 3GB overall, because of its greater data rate. (explain)

GeForce GTX 970 224000 MB/sec
GeForce GTX 580 3GB 192384 MB/sec
Difference: 31616 (16%)

Texel Rate

The GeForce GTX 970 should be much (approximately 121%) more effective at anisotropic filtering than the GeForce GTX 580 3GB. (explain)

GeForce GTX 970 109200 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 59792 (121%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970 is superior to the GeForce GTX 580 3GB, by a large margin. (explain)

GeForce GTX 970 67200 Mpixels/sec
GeForce GTX 580 3GB 37056 Mpixels/sec
Difference: 30144 (81%)

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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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