GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 460

Intro

Compare all that to the GeForce GTX 460, which has 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 Rasterization Operator Units.

GeForce GTX 460		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

The GeForce GTX 460, in theory, should be much faster than the GeForce 9500 GT 1GB GDDR3 in general. (explain)

GeForce GTX 460		86400 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 60800 (238%)

Texel Rate

The GeForce GTX 460 is a lot (approximately 330%) more effective at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 460		37800 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 29000 (330%)

Pixel Rate

The GeForce GTX 460 is quite a bit (more or less 268%) faster with regards to AA than the GeForce 9500 GT 1GB GDDR3, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		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 max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
