Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon R9 M295X
IntroThe GeForce GTX 285 1GB makes use of a 55 nm design. nVidia has clocked the core frequency at 648 MHz. The GDDR3 memory works at a frequency of 1242 MHz on this particular model. It features 240 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the Radeon R9 M295X, which features core clock speeds of 750 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 M295X should in theory be a little bit superior to the GeForce GTX 285 1GB overall. (explain)
Texel RateThe Radeon R9 M295X will be much (more or less 85%) better at texture filtering than the GeForce GTX 285 1GB. (explain)
Pixel RateThe Radeon R9 M295X should be a small bit (more or less 16%) faster with regards to FSAA than the GeForce GTX 285 1GB, and capable of handling higher screen 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 (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
