GeForce 9600 GT 1GB vs GeForce GTX 650

Intro

The GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific model. It features 64 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the GeForce GTX 650, which features a core clock frequency of 1058 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 TAUs, and 16 Raster Operation Units.

The GeForce GTX 650 is much (approximately 63%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)

GeForce GTX 650 33856 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 13056 (63%)

Pixel Rate

The GeForce GTX 650 should be quite a bit (approximately 63%) faster with regards to anti-aliasing than the GeForce 9600 GT 1GB, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 650 16928 Mpixels/sec
GeForce 9600 GT 1GB 10400 Mpixels/sec
Difference: 6528 (63%)

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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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