Compare any two graphics cards:
Radeon HD 4870 2GB vs Radeon R9 M295X
IntroThe Radeon HD 4870 2GB makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this card. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.Compare that to the Radeon R9 M295X, which makes use of a 28 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 RAM works at a frequency of 1375 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 M295X should in theory be much superior to the Radeon HD 4870 2GB in general. (explain)
Texel RateThe Radeon R9 M295X should be a lot (about 220%) faster with regards to anisotropic filtering than the Radeon HD 4870 2GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 M295X is the winner, by a large margin. (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 MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
