Radeon HD 5830 vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which uses a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 5830, in theory, should be a lot faster than the Radeon R9 M370X in general. (explain)

Radeon HD 5830		128000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 56000 (78%)

Texel Rate

The Radeon HD 5830 is a lot (about 40%) more effective at texture filtering than the Radeon R9 M370X. (explain)

Radeon HD 5830		44800 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 12800 (40%)

Pixel Rate

Both cards have exactly the same pixel rate, so theoretically they should be equally good at at anti-aliasing, and be capable of handling the same screen resolutions. (explain)

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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
