Radeon HD 5670 vs Radeon R7 M260X

Intro

The Radeon HD 5670 features clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Radeon R7 M260X, which has a clock frequency of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon R7 M260X is much (about 28%) faster with regards to anisotropic filtering than the Radeon HD 5670. (explain)

Radeon R7 M260X 19800 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 4300 (28%)

Pixel Rate

The Radeon R7 M260X is a small bit (more or less 6%) faster with regards to AA than the Radeon HD 5670, and also will be able to handle higher screen resolutions better. (explain)

Radeon R7 M260X 6600 Mpixels/sec
Radeon HD 5670 6200 Mpixels/sec
Difference: 400 (6%)

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: Memory bandwidth is the max amount of information (in units of 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. In the case of DDR RAM, 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
