Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs Radeon R7 M265
IntroThe GeForce 9500 GT 512MB GDDR3 comes with a GPU core speed of 550 MHz, and the 512 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare that to the Radeon R7 M265, which has a clock frequency of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R7 M265 should be quite a bit faster than the GeForce 9500 GT 512MB GDDR3 overall. (explain)
Texel RateThe Radeon R7 M265 will be much (more or less 98%) more effective at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R7 M265 is the winner, and very much so. (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 MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 processed in one second. This number is calculated by multiplying the total amount of texture units by the core 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 processed in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
