Radeon HD 7950 vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 7950 should in theory be a lot better than the Radeon R9 M370X overall. (explain)

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

Texel Rate

The Radeon HD 7950 should be a lot (approximately 180%) better at AF than the Radeon R9 M370X. (explain)

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

Pixel Rate

The Radeon HD 7950 will be quite a bit (more or less 100%) more effective at full screen anti-aliasing than the Radeon R9 M370X, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 7950		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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high 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 the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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