GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 470

Intro

Compare all that to the GeForce GTX 470, which comes with GPU core speed of 607 MHz, and 1280 MB of GDDR5 memory running at 837 MHz through a 320-bit bus. It also is comprised of 448 Stream Processors, 56 Texture Address Units, and 40 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3		50 Watts
GeForce GTX 470		215 Watts
	Difference: 165 Watts (330%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 470 will be 423% faster than the GeForce 9500 GT 512MB GDDR3 in general, because of its greater bandwidth. (explain)

GeForce GTX 470		133920 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 108320 (423%)

Texel Rate

The GeForce GTX 470 is quite a bit (more or less 286%) more effective at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce GTX 470		33992 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 25192 (286%)

Pixel Rate

The GeForce GTX 470 will be much (about 452%) more effective at FSAA than the GeForce 9500 GT 512MB GDDR3, and also capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 19880 (452%)

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 (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 speed. If the card has 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock 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 maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 ability to reach the max fill rate.
