Compare any two graphics cards:
Radeon HD 6670 (OEM) 1GB vs Radeon R9 M265X
IntroThe Radeon HD 6670 (OEM) 1GB has a clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.Compare those specifications to the Radeon R9 M265X, which features a core clock speed of 575 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M265X should be just a bit faster than the Radeon HD 6670 (OEM) 1GB in general. (explain)
Texel RateThe Radeon R9 M265X is just a bit (more or less 20%) better at anisotropic filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe Radeon R9 M265X is much (about 44%) better at anti-aliasing than the Radeon HD 6670 (OEM) 1GB, and also will be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
