GeForce 9500 GT DDR2 vs GeForce GTX 960

Intro

Compare that to the GeForce GTX 960, which has core speeds of 1127 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 960		120 Watts
	Difference: 70 Watts (140%)

Memory Bandwidth

The GeForce GTX 960 should in theory be quite a bit faster than the GeForce 9500 GT DDR2 overall. (explain)

GeForce GTX 960		112000 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 96000 (600%)

Texel Rate

The GeForce GTX 960 is much (about 720%) more effective at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 63328 (720%)

Pixel Rate

The GeForce GTX 960 will be quite a bit (approximately 720%) more effective at AA than the GeForce 9500 GT DDR2, and also should be capable of handling higher resolutions better. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 31664 (720%)

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 largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR 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 amount of texture units by the core clock speed of the chip. The higher 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 could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 reach the max fill rate.
