Compare any two graphics cards:
Radeon R9 M265X vs Radeon R9 M375X
IntroThe Radeon R9 M265X makes use of a 28 nm design. AMD has set the core frequency at 575 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.Compare that to the Radeon R9 M375X, which uses a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 memory works at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe Radeon R9 M375X is quite a bit (more or less 77%) more effective at texture filtering than the Radeon R9 M265X. (explain)
Pixel RateThe Radeon R9 M375X will be much (about 77%) better at full screen anti-aliasing than the Radeon R9 M265X, and will be capable of handling 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
