Radeon HD 5770 vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5770 will be 7% faster than the Radeon R9 M370X in general, because of its higher data rate. (explain)

Radeon HD 5770		76800 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 4800 (7%)

Texel Rate

The Radeon HD 5770 is a little bit (more or less 6%) better at texture filtering than the Radeon R9 M370X. (explain)

Radeon HD 5770		34000 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 2000 (6%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 5770 is a better choice, though not by far. (explain)

Radeon HD 5770		13600 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 800 (6%)

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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 - the lower the bandwidth is, the lower the potential to get to the max fill rate.
