Compare any two graphics cards:
GeForce GT 320 vs Radeon R9 380 2G
IntroThe GeForce GT 320 has a core clock speed of 540 MHz and a GDDR3 memory frequency of 790 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 72 SPUs, 24 TAUs, and 8 ROPs.Compare that to the Radeon R9 380 2G, which uses a 28 nm design. AMD has set the core frequency at 970 MHz. The GDDR5 RAM works at a speed of 1425 MHz on this model. It features 1792 SPUs as well as 112 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 380 2G should theoretically perform a lot faster than the GeForce GT 320 in general. (explain)
Texel RateThe Radeon R9 380 2G should be a lot (approximately 738%) more effective at texture filtering than the GeForce GT 320. (explain)
Pixel RateThe Radeon R9 380 2G is much (more or less 619%) more effective at anti-aliasing than the GeForce GT 320, and will be able to handle 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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
