Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
Radeon R9 M295X		125 Watts
	Difference: 82 Watts (191%)

Memory Bandwidth

In theory, the Radeon R9 M295X is 511% faster than the Radeon HD 5570 in general, because of its greater data rate. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 147200 (511%)

Texel Rate

The Radeon R9 M295X is quite a bit (more or less 638%) more effective at AF than the Radeon HD 5570. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 83000 (638%)

Pixel Rate

The Radeon R9 M295X should be a lot (more or less 362%) faster with regards to full screen anti-aliasing than the Radeon HD 5570, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 18800 (362%)

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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
