Compare any two graphics cards:
Radeon HD 6670 (OEM) vs Radeon R9 M295X
IntroThe Radeon HD 6670 (OEM) has a core clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It features 480 SPUs, 24 Texture Address Units, and 8 ROPs.Compare those specs to the Radeon R9 M295X, which has core clock speeds of 750 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 M295X should in theory be quite a bit better than the Radeon HD 6670 (OEM) overall. (explain)
Texel RateThe Radeon R9 M295X is a lot (about 400%) better at texture filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon R9 M295X is superior to the Radeon HD 6670 (OEM), by a large margin. (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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
