GeForce 9600 GT 1GB vs GeForce GTX 465

Intro

Compare all that to the GeForce GTX 465, which uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM runs at a speed of 802 MHz on this specific model. It features 352 SPUs along with 44 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB		95 Watts
GeForce GTX 465		200 Watts
	Difference: 105 Watts (111%)

Memory Bandwidth

In theory, the GeForce GTX 465 will be 78% faster than the GeForce 9600 GT 1GB in general, due to its greater data rate. (explain)

GeForce GTX 465		102592 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 44992 (78%)

Texel Rate

The GeForce GTX 465 should be much (more or less 28%) more effective at texture filtering than the GeForce 9600 GT 1GB. (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 5908 (28%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 465 is the winner, by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 9024 (87%)

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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
