GeForce GTX 580 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which uses a 28 nm design. AMD has clocked the core speed at 1030 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this particular model. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 580 should be 1236% faster than the Radeon R5 M330 overall, due to its higher data rate. (explain)

GeForce GTX 580		192384 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 177984 (1236%)

Texel Rate

The GeForce GTX 580 should be quite a bit (about 140%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce GTX 580		49408 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 28808 (140%)

Pixel Rate

The GeForce GTX 580 should be much (about 350%) more effective at full screen anti-aliasing than the Radeon R5 M330, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 28816 (350%)

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 maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock 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 in a second.

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