Compare any two graphics cards:
GeForce 9800 GTX vs Radeon R9 M265X
IntroThe GeForce 9800 GTX makes use of a 65 nm design. nVidia has set the core speed at 675 MHz. The GDDR3 memory runs at a frequency of 1100 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon R9 M265X, which features core clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R9 M265X should in theory be a little bit better than the GeForce 9800 GTX in general. (explain)
Texel RateThe GeForce 9800 GTX is much (about 88%) faster with regards to AF than the Radeon R9 M265X. (explain)
Pixel RateThe GeForce 9800 GTX should be just a bit (more or less 17%) better at anti-aliasing than the Radeon R9 M265X, and will be able to handle 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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
