Compare any two graphics cards:
Radeon HD 4350 vs Radeon R7 250X 2GB
IntroThe Radeon HD 4350 has a GPU core clock speed of 575 MHz, and the 512 MB of DDR2 RAM is set to run at 500 MHz through a 64-bit bus. It also is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare all that to the Radeon R7 250X 2GB, which has a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R7 250X 2GB, in theory, should perform quite a bit faster than the Radeon HD 4350 overall. (explain)
Texel RateThe Radeon R7 250X 2GB is a lot (approximately 770%) faster with regards to AF than the Radeon HD 4350. (explain)
Pixel RateThe Radeon R7 250X 2GB will be quite a bit (approximately 596%) better at FSAA than the Radeon HD 4350, and capable of handling higher screen resolutions more effectively. (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 moved across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 can be processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
