Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 5870, in theory, should perform quite a bit faster than the Radeon R5 M330 in general. (explain)

Radeon HD 5870 153600 MB/sec
Radeon R5 M330 14400 MB/sec
Difference: 139200 (967%)

Texel Rate

The Radeon HD 5870 should be much (more or less 230%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

Radeon HD 5870 68000 Mtexels/sec
Radeon R5 M330 20600 Mtexels/sec
Difference: 47400 (230%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5870 is superior to the Radeon R5 M330, by a large margin. (explain)

Radeon HD 5870 27200 Mpixels/sec
Radeon R5 M330 8240 Mpixels/sec
Difference: 18960 (230%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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