Radeon HD 5570 vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should in theory be a lot better than the Radeon HD 5570 overall. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 43200 (150%)

Texel Rate

The Radeon R9 M365X should be a lot (approximately 185%) better at texture filtering than the Radeon HD 5570. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 24000 (185%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M365X is the winner, and very much so. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 9600 (185%)

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 largest amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
