Compare any two graphics cards:
Radeon HD 6450 (OEM) vs Radeon R9 285
IntroThe Radeon HD 6450 (OEM) comes with a GPU clock speed of 625 MHz, and the 512 MB of GDDR3 memory runs at 800 MHz through a 64-bit bus. It also is made up of 160 SPUs, 8 Texture Address Units, and 4 ROPs.Compare those specifications to the Radeon R9 285, which comes with a clock frequency of 918 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It features 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 285 will be 1275% faster than the Radeon HD 6450 (OEM) overall, due to its greater data rate. (explain)
Texel RateThe Radeon R9 285 should be a lot (more or less 1956%) faster with regards to anisotropic filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe Radeon R9 285 is quite a bit (about 1075%) more effective at full screen anti-aliasing than the Radeon HD 6450 (OEM), and should be able to handle 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 largest amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
