Radeon HD 5670 vs Radeon R9 M370X

Intro

The Radeon HD 5670 has a GPU core clock speed of 775 MHz, and the 1024 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is made up of 400(80x5) Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Compare those specifications to the Radeon R9 M370X, which uses a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M370X, in theory, should perform a bit faster than the Radeon HD 5670 in general. (explain)

Radeon R9 M370X 72000 MB/sec
Radeon HD 5670 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X should be quite a bit (approximately 106%) faster with regards to anisotropic filtering than the Radeon HD 5670. (explain)

Radeon R9 M370X 32000 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 16500 (106%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M370X is superior to the Radeon HD 5670, and very much so. (explain)

Radeon R9 M370X 12800 Mpixels/sec
Radeon HD 5670 6200 Mpixels/sec
Difference: 6600 (106%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
