Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon R9 380 2G
IntroThe GeForce GT 340 1GB features core speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the Radeon R9 380 2G, which uses a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 RAM runs at a speed of 1425 MHz on this specific model. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon R9 380 2G should in theory be a lot better than the GeForce GT 340 1GB in general. (explain)
Texel RateThe Radeon R9 380 2G should be much (approximately 517%) more effective at AF than the GeForce GT 340 1GB. (explain)
Pixel RateThe Radeon R9 380 2G should be a lot (about 605%) better at full screen anti-aliasing than the GeForce GT 340 1GB, and also capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 applied per second. This is calculated by multiplying the total amount of 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 amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
