GeForce 9600 GSO 768MB vs GeForce GTX 650

Intro

Compare those specifications to the GeForce GTX 650, which uses a 28 nm design. nVidia has set the core frequency at 1058 MHz. The GDDR5 memory works at a speed of 1250 MHz on this card. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

GeForce GTX 650		64 Watts
GeForce 9600 GSO 768MB		84 Watts
	Difference: 20 Watts (31%)

Memory Bandwidth

The GeForce GTX 650 should in theory perform quite a bit faster than the GeForce 9600 GSO 768MB in general. (explain)

GeForce GTX 650		80000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 41600 (108%)

Texel Rate

The GeForce GTX 650 is quite a bit (about 28%) faster with regards to AF than the GeForce 9600 GSO 768MB. (explain)

GeForce GTX 650		33856 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 7456 (28%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 is superior to the GeForce 9600 GSO 768MB, and very much so. (explain)

GeForce GTX 650		16928 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 10328 (156%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen 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 texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 potential to reach the max fill rate.
