Radeon HD 5770 vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which features a clock speed of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5770 should be 7% quicker than the Radeon R9 M370X in general, due to its greater data rate. (explain)

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

Texel Rate

The Radeon HD 5770 should be a small bit (about 6%) better at AF than the Radeon R9 M370X. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 5770 is superior to the Radeon R9 M370X, but it probably won't make a huge difference. (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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
