GeForce 9500 GT DDR2 vs GeForce GTX 780 Ti

Intro

Compare those specs to the GeForce GTX 780 Ti, which has a clock frequency of 875 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit bus, and uses a 28 nm design. It is made up of 2880 SPUs, 240 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 200 Watts (400%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 780 Ti should be a lot faster than the GeForce 9500 GT DDR2 overall. (explain)

GeForce GTX 780 Ti		336000 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 320000 (2000%)

Texel Rate

The GeForce GTX 780 Ti will be a lot (more or less 2286%) more effective at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 201200 (2286%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 780 Ti is a better choice, and very much so. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 37600 (855%)

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 data (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
