Radeon HD 5670 vs Radeon R7 M260X

Intro

The Radeon HD 5670 has 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 TAUs and 8 ROPs.

Compare all of that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core speed at 825 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 M260X should be quite a bit (approximately 28%) better at AF than the Radeon HD 5670. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 M260X is superior to the Radeon HD 5670, but it probably won't make a huge difference. (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: Bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
