GeForce 9800 GTX vs GeForce GTX 650

Intro

The GeForce 9800 GTX comes with a clock speed of 675 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit memory bus, and uses a 65 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare that to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core speed at 1058 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this specific card. It features 384 SPUs along with 32 Texture Address Units and 16 ROPs.

GeForce GTX 650 33856 Mtexels/sec
Difference: 9344 (28%)

Pixel Rate

The GeForce GTX 650 should be quite a bit (more or less 57%) better at AA than the GeForce 9800 GTX, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 650 16928 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 6128 (57%)

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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
