GeForce GTX 570 vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which uses a 28 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 RAM works at a speed of 1375 MHz on this specific card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M295X		125 Watts
GeForce GTX 570		219 Watts
	Difference: 94 Watts (75%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X should be a small bit faster than the GeForce GTX 570 overall. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce GTX 570		152000 MB/sec
	Difference: 24000 (16%)

Texel Rate

The Radeon R9 M295X is quite a bit (more or less 119%) faster with regards to anisotropic filtering than the GeForce GTX 570. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GTX 570		43920 Mtexels/sec
	Difference: 52080 (119%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 570 is the winner, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 5280 (22%)

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 max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
