Compare any two graphics cards:
Radeon HD 5670 vs Radeon R7 M260X
IntroThe Radeon HD 5670 has core speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 ROPs.Compare those specifications to the Radeon R7 M260X, which uses a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateThe Radeon R7 M260X is quite a bit (about 28%) better at texture filtering than the Radeon HD 5670. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R7 M260X is a better choice, but it probably won't make a huge difference. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen 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 texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
