GeForce GTX 950M vs Radeon HD 5970

Intro

Compare those specifications to the Radeon HD 5970, which features a GPU core clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also features 1600 Stream Processors, 160 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 950M		32000 MB/sec
	Difference: 224000 (700%)

Texel Rate

The Radeon HD 5970 should be a lot (more or less 535%) more effective at AF than the GeForce GTX 950M. (explain)

Radeon HD 5970		232000 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 195440 (535%)

Pixel Rate

The Radeon HD 5970 should be quite a bit (about 535%) better at AA than the GeForce GTX 950M, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 78176 (535%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
