Compare any two graphics cards:
Radeon HD 7870 vs Radeon R9 M375X
IntroThe Radeon HD 7870 has a GPU clock speed of 1000 MHz, and the 2048 MB of GDDR5 memory is set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 32 ROPs.Compare those specifications 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 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 7870 should perform much faster than the Radeon R9 M375X in general. (explain)
Texel RateThe Radeon HD 7870 is quite a bit (approximately 97%) more effective at texture filtering than the Radeon R9 M375X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 7870 is a better choice, 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 transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This number is calculated 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
