Compare any two graphics cards:
GeForce 9400 GT 256MB vs Radeon R7 240
IntroThe GeForce 9400 GT 256MB has a GPU core clock speed of 550 MHz, and the 256 MB of GDDR2 RAM runs at 400 MHz through a 128-bit bus. It also is comprised of 16 Stream Processors, 8 TAUs, and 4 ROPs.Compare those specifications to the Radeon R7 240, which has a core clock frequency of 730 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R7 240 should perform quite a bit faster than the GeForce 9400 GT 256MB overall. (explain)
Texel RateThe Radeon R7 240 is quite a bit (approximately 232%) more effective at AF than the GeForce 9400 GT 256MB. (explain)
Pixel RateThe Radeon R7 240 should be much (about 165%) faster with regards to AA than the GeForce 9400 GT 256MB, and also should be able to handle 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: Bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
