Compare any two graphics cards:
Radeon HD 4870 1GB vs Radeon R9 M375X
IntroThe Radeon HD 4870 1GB makes use of a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this specific card. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.Compare that to the Radeon R9 M375X, which comes with core speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 4870 1GB should theoretically be a lot superior to the Radeon R9 M375X in general. (explain)
Texel RateThe Radeon R9 M375X will be a lot (more or less 35%) more effective at AF than the Radeon HD 4870 1GB. (explain)
Pixel RateThe Radeon R9 M375X is quite a bit (more or less 35%) better at full screen anti-aliasing than the Radeon HD 4870 1GB, and able to handle higher resolutions without losing too much performance. (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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 amount of pixels the graphics card can possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
