GeForce 9600 GT 1GB vs GeForce GTX 650

Intro

The GeForce 9600 GT 1GB makes use of a 65/55 nm design. nVidia has set the core speed at 650 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this specific card. It features 64 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 650, which has a core clock frequency of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 32 TAUs, and 16 ROPs.

The GeForce GTX 650 is a lot (more or less 63%) more effective at AF 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 much (more or less 63%) better at FSAA than the GeForce 9600 GT 1GB, and should be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 output 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.
