Compare any two graphics cards:
Radeon HD 4830 1GB vs Radeon R9 M265X
IntroThe Radeon HD 4830 1GB uses a 55 nm design. AMD has clocked the core frequency at 575 MHz. The GDDR4 memory works at a speed of 900 MHz on this particular card. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon R9 M265X, which has a clock frequency of 575 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M265X is 25% quicker than the Radeon HD 4830 1GB in general, due to its higher data rate. (explain)
Texel RateThe Radeon R9 M265X will be much (about 25%) better at texture filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateBoth cards have the exact same pixel fill rate, so in theory they should be equally good at at full screen anti-aliasing, and be capable of handling the same screen resolutions. (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 information (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
