GeForce GTX 580 vs Radeon R5 M330

Intro

Compare all of that to the Radeon R5 M330, which comes with core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 will 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 is a lot (approximately 140%) better 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

If using a high resolution is important to you, then the GeForce GTX 580 is superior to the Radeon R5 M330, and very much so. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
