Compare any two graphics cards:
Radeon HD 4890 1GB vs Radeon R7 360
IntroThe Radeon HD 4890 1GB makes use of a 55 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory runs at a speed of 975 MHz on this specific model. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon R7 360, which has GPU clock speed of 1050 MHz, and 2048 MB of GDDR5 RAM set to run at 1625 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 48 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4890 1GB is 20% faster than the Radeon R7 360 overall, due to its greater data rate. (explain)
Texel RateThe Radeon R7 360 should be quite a bit (more or less 26%) better at AF than the Radeon HD 4890 1GB. (explain)
Pixel RateThe Radeon R7 360 will be a bit (more or less 5%) faster with regards to AA than the Radeon HD 4890 1GB, and will be able to handle 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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, 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 most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
