Compare any two graphics cards:
GeForce GT 320 vs Radeon R9 380 4G
IntroThe GeForce GT 320 uses a 40 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 RAM works at a speed of 790 MHz on this particular card. It features 72 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon R9 380 4G, which has a GPU core clock speed of 970 MHz, and 4096 MB of GDDR5 RAM running at 1425 MHz through a 256-bit bus. It also is comprised of 1792 SPUs, 112 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 380 4G should perform a lot faster than the GeForce GT 320 overall. (explain)
Texel RateThe Radeon R9 380 4G is a lot (about 738%) more effective at texture filtering than the GeForce GT 320. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 380 4G is a better choice, and very much so. (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 (counted in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 maximum fill rate.
