GeForce 9500 GT 1GB GDDR3 vs Radeon R9 M295X

Intro

Compare all that to the Radeon R9 M295X, which uses a 28 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 memory is set to run at a speed of 1375 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

	Difference: 150400 (588%)

Texel Rate

The Radeon R9 M295X should be much (more or less 991%) better at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 87200 (991%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M295X is superior to the GeForce 9500 GT 1GB GDDR3, and very much so. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 19600 (445%)

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 information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video 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 amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
