Compare any two graphics cards:
Radeon HD 6670 (OEM) 1GB vs Radeon R7 250X
IntroThe Radeon HD 6670 (OEM) 1GB makes use of a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific model. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the Radeon R7 250X, which features a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 250X should be 13% quicker than the Radeon HD 6670 (OEM) 1GB in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon R7 250X is quite a bit (more or less 108%) faster with regards to texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe Radeon R7 250X is much (about 150%) better at anti-aliasing than the Radeon HD 6670 (OEM) 1GB, and also will be capable of handling higher screen resolutions without losing too much performance. (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 max amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
