Radeon HD 5570 vs Radeon R9 M380

Intro

Compare that to the Radeon R9 M380, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory works at a speed of 1500 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380, in theory, should perform quite a bit faster than the Radeon HD 5570 overall. (explain)

Radeon R9 M380		96000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 67200 (233%)

Texel Rate

The Radeon R9 M380 will be much (about 208%) more effective at texture filtering than the Radeon HD 5570. (explain)

Radeon R9 M380		40000 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 27000 (208%)

Pixel Rate

The Radeon R9 M380 is much (about 208%) more effective at anti-aliasing than the Radeon HD 5570, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 M380		16000 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 10800 (208%)

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
