Compare any two graphics cards:
Radeon HD 4850 1GB vs Radeon HD 7750
IntroThe Radeon HD 4850 1GB makes use of a 55 nm design. AMD has clocked the core speed at 625 MHz. The GDDR4 memory works at a frequency of 993 MHz on this particular card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon HD 7750, which has a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7750 is 13% quicker than the Radeon HD 4850 1GB overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 7750 should be a small bit (more or less 2%) faster with regards to anisotropic filtering than the Radeon HD 4850 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 7750 is superior to the Radeon HD 4850 1GB, by far. (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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 can possibly write to its local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
