Compare any two graphics cards:
GeForce GT 420 vs Radeon R9 M375
IntroThe GeForce GT 420 makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this card. It features 48 SPUs along with 8 TAUs and 4 Rasterization Operator Units.Compare those specifications to the Radeon R9 M375, which has GPU clock speed of 1015 MHz, and 4096 MB of DDR3 memory running at 1100 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M375 will be 22% faster than the GeForce GT 420 overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon R9 M375 is quite a bit (approximately 625%) faster with regards to AF than the GeForce GT 420. (explain)
Pixel RateThe Radeon R9 M375 is a lot (approximately 480%) more effective at full screen anti-aliasing than the GeForce GT 420, and also should be capable of handling higher screen resolutions while still performing well. (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 moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
