GeForce GTX 580 vs Radeon R5 M330

Intro

Compare that to the Radeon R5 M330, which has a clock speed of 1030 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit memory bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 should perform much faster than the Radeon R5 M330 overall. (explain)

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

Texel Rate

The GeForce GTX 580 is quite a bit (more or less 140%) more effective at AF 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 will be quite a bit (more or less 350%) more effective at FSAA than the Radeon R5 M330, and should be capable of handling higher resolutions without losing too much performance. (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 max amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
