GeForce 9500 GT 512MB GDDR3 vs Geforce GTX 760

Intro

Compare all that to the Geforce GTX 760, which comes with a GPU core clock speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also is comprised of 1152 Stream Processors, 96 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3		50 Watts
Geforce GTX 760		170 Watts
	Difference: 120 Watts (240%)

Memory Bandwidth

In theory, the Geforce GTX 760 should be 651% faster than the GeForce 9500 GT 512MB GDDR3 overall, because of its greater bandwidth. (explain)

Geforce GTX 760		192256 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 166656 (651%)

Texel Rate

The Geforce GTX 760 should be a lot (about 969%) better at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 85280 (969%)

Pixel Rate

The Geforce GTX 760 should be much (approximately 613%) better at anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and will be capable of handling higher resolutions without losing too much performance. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 26960 (613%)

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 (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
