Radeon HD 5670 vs Radeon R9 M370X

Intro

Compare that to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M370X should be 13% faster than the Radeon HD 5670 overall, because of its greater bandwidth. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X will be much (more or less 106%) faster with regards to AF than the Radeon HD 5670. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 16500 (106%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M370X is the winner, by far. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 6600 (106%)

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 max amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to get to the maximum fill rate.
