Compare any two graphics cards:
Radeon HD 6670 (OEM) 1GB vs Radeon R7 M260X
IntroThe Radeon HD 6670 (OEM) 1GB comes with a GPU clock speed of 800 MHz, and the 1024 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is comprised of 480 Stream Processors, 24 TAUs, and 8 ROPs.Compare that to the Radeon R7 M260X, which features a clock frequency of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have the exact same bandwidth, so in theory they should perform the same. (explain)
Texel RateThe Radeon R7 M260X should be just a bit (more or less 3%) faster with regards to AF than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe Radeon R7 M260X is a little bit (approximately 3%) faster with regards to full screen anti-aliasing than the Radeon HD 6670 (OEM) 1GB, and will be capable of handling higher screen resolutions better. (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 max amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
