GeForce 9500 GT DDR2 vs Radeon R9 M280X

Intro

Compare that to the Radeon R9 M280X, which features GPU core speed of 900 MHz, and 4096 MB of GDDR5 memory running at 1375 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 72000 (450%)

Texel Rate

The Radeon R9 M280X will be much (about 473%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 41600 (473%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M280X is the winner, and very much so. (explain)

Radeon R9 M280X		14400 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 10000 (227%)

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 (counted in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
