Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 7790
IntroThe GeForce GT 240 GDDR5 comes with a core clock speed of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 Raster Operation Units.Compare those specs to the Radeon HD 7790, which uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this particular card. It features 896 SPUs along with 56 TAUs and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7790 is 76% quicker than the GeForce GT 240 GDDR5 overall, due to its higher data rate. (explain)
Texel RateThe Radeon HD 7790 will be quite a bit (approximately 218%) better at AF than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 7790 should be a lot (approximately 264%) faster with regards to FSAA than the GeForce GT 240 GDDR5, and will be able to handle higher resolutions better. (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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
