GeForce 9500 GT 512MB GDDR3 vs GeForce GTX Titan

Intro

Compare those specs to the GeForce GTX Titan, which comes with a core clock speed of 837 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 384-bit bus, and makes use of a 28 nm design. It features 2688 SPUs, 224 TAUs, and 48 Raster Operation Units.

GeForce 9500 GT 512MB GDDR3		50 Watts
GeForce GTX Titan		250 Watts
	Difference: 200 Watts (400%)

Memory Bandwidth

In theory, the GeForce GTX Titan should be a lot faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 262784 (1027%)

Texel Rate

The GeForce GTX Titan should be much (more or less 2031%) more effective at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 178688 (2031%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan is the winner, and very much so. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 35776 (813%)

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

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
