Compare any two graphics cards:
Radeon HD 4550 512MB vs Radeon R9 M395X
IntroThe Radeon HD 4550 512MB makes use of a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR3 memory runs at a frequency of 800 MHz on this particular card. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 ROPs.Compare those specs to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has clocked the core speed at 723 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 M395X should be 1150% quicker than the Radeon HD 4550 512MB overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 M395X is quite a bit (more or less 1828%) better at AF than the Radeon HD 4550 512MB. (explain)
Pixel RateThe Radeon R9 M395X should be much (about 864%) more effective at FSAA than the Radeon HD 4550 512MB, and will be capable of handling higher screen resolutions without slowing down too much. (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 information (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
