GeForce GTX 570 vs Radeon R9 M380

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 570 should in theory perform 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 will be a little bit (more or less 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

The GeForce GTX 570 is quite a bit (approximately 83%) better at FSAA than the Radeon R9 M380, and also capable of handling higher resolutions better. (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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
