Radeon HD 7950 3GB vs Radeon R9 M370X

Intro

Compare those specifications 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 runs at a frequency of 1125 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7950 3GB should perform a lot faster than the Radeon R9 M370X in general. (explain)

Radeon HD 7950 3GB		240000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 168000 (233%)

Texel Rate

The Radeon HD 7950 3GB will be a lot (approximately 180%) more effective at AF than the Radeon R9 M370X. (explain)

Radeon HD 7950 3GB		89600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 57600 (180%)

Pixel Rate

The Radeon HD 7950 3GB should be quite a bit (more or less 100%) better at AA than the Radeon R9 M370X, and will be able to handle higher resolutions more effectively. (explain)

Radeon HD 7950 3GB		25600 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 12800 (100%)

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 data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total number 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
