Compare any two graphics cards:
GeForce 8400 GS 512MB vs Radeon R5 M230
IntroThe GeForce 8400 GS 512MB makes use of a 80 nm design. nVidia has set the core frequency at 650 MHz. The DDR2 RAM is set to run at a speed of 400 MHz on this particular card. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.Compare that to the Radeon R5 M230, which comes with a core clock frequency of 780 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 64-bit bus, and makes use of a 28 nm design. It features 320 SPUs, 20 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon R5 M230 should in theory be a lot superior to the GeForce 8400 GS 512MB overall. (explain)
Texel RateThe Radeon R5 M230 should be much (approximately 200%) more effective at anisotropic filtering than the GeForce 8400 GS 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R5 M230 is a better choice, but only just. (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 data (in units of megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling 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 video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
