GeForce 9500 GT 1GB GDDR3 vs GeForce GTX Titan

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
GeForce GTX Titan		250 Watts
	Difference: 200 Watts (400%)

Memory Bandwidth

In theory, the GeForce GTX Titan should be 1027% faster than the GeForce 9500 GT 1GB GDDR3 in general, because of its greater bandwidth. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 262784 (1027%)

Texel Rate

The GeForce GTX Titan is quite a bit (more or less 2031%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 178688 (2031%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan is the winner, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 9500 GT 1GB 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 max amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
