GeForce GTX 470 vs GeForce GTX 650

Intro

The GeForce GTX 470 comes with a clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also features a 320-bit bus, and makes use of a 40 nm design. It is comprised of 448 SPUs, 56 Texture Address Units, and 40 ROPs.

Compare those specifications to the GeForce GTX 650, which features clock speeds of 1058 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

GeForce GTX 650 80000 MB/sec
Difference: 53920 (67%)

Texel Rate

The GeForce GTX 470 is a small bit (about 0%) faster with regards to texture filtering than the GeForce GTX 650. (explain)

GeForce GTX 470 33992 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 136 (0%)

Pixel Rate

The GeForce GTX 470 is much (about 43%) faster with regards to full screen anti-aliasing than the GeForce GTX 650, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 650 16928 Mpixels/sec
Difference: 7352 (43%)

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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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