GeForce GTX 570 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which features GPU clock speed of 1030 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 570 should in theory be much superior to the Radeon R5 M330 overall. (explain)

GeForce GTX 570		152000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 137600 (956%)

Texel Rate

The GeForce GTX 570 is a lot (approximately 113%) more effective at texture filtering than the Radeon R5 M330. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 23320 (113%)

Pixel Rate

The GeForce GTX 570 is a lot (more or less 255%) better at AA than the Radeon R5 M330, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 21040 (255%)

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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
