Compare any two graphics cards:
Radeon HD 4870 1GB vs Radeon R7 360
IntroThe Radeon HD 4870 1GB makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this particular model. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon R7 360, which uses a 28 nm design. AMD has clocked the core speed at 1050 MHz. The GDDR5 memory runs at a frequency of 1625 MHz on this model. It features 768 SPUs along with 48 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4870 1GB will be 11% faster than the Radeon R7 360 in general, due to its greater data rate. (explain)
Texel RateThe Radeon R7 360 is quite a bit (approximately 68%) more effective at anisotropic filtering than the Radeon HD 4870 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R7 360 is a better choice, 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

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
