VS

GeForce 9600 GT 1GB vs GeForce GTX 650

Intro

The GeForce 9600 GT 1GB has core speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 64 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare all that to the GeForce GTX 650, which features GPU clock speed of 1058 MHz, and 1024 MB of GDDR5 memory set to run at 1250 MHz through a 128-bit bus. It also is made up of 384 SPUs, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 64 Watts
GeForce 9600 GT 1GB 95 Watts
Difference: 31 Watts (48%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 will be 39% faster than the GeForce 9600 GT 1GB overall, because of its greater bandwidth. (explain)

GeForce GTX 650 80000 MB/sec
GeForce 9600 GT 1GB 57600 MB/sec
Difference: 22400 (39%)

Texel Rate

The GeForce GTX 650 should be much (approximately 63%) better 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 is quite a bit (approximately 63%) faster with regards to FSAA than the GeForce 9600 GT 1GB, and also should be able to handle higher screen resolutions without losing too much performance. (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 maximum amount of information (measured in MB per second) that can be transported 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 memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, 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 could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
