GeForce 9500 GT DDR2 vs GeForce GTX 460

Intro

Compare all that to the GeForce GTX 460, which features core clock speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 RAM. It features 336 SPUs along with 56 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 460		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

In theory, the GeForce GTX 460 is 440% quicker than the GeForce 9500 GT DDR2 overall, because of its higher bandwidth. (explain)

GeForce GTX 460		86400 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 70400 (440%)

Texel Rate

The GeForce GTX 460 will be a lot (more or less 330%) more effective at AF than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 460		37800 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 29000 (330%)

Pixel Rate

The GeForce GTX 460 should be quite a bit (approximately 268%) more effective at FSAA than the GeForce 9500 GT DDR2, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 11800 (268%)

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 maximum amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling 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 that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
