GeForce GTX 570 vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which features a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 570, in theory, should be quite a bit faster than the Radeon R9 M380 in general. (explain)

GeForce GTX 570		152000 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 56000 (58%)

Texel Rate

The GeForce GTX 570 should be a small bit (about 10%) better at AF than the Radeon R9 M380. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 3920 (10%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 570 is the winner, by a large margin. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 13280 (83%)

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 data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
