Compare any two graphics cards:
Radeon HD 6450 (OEM) vs Radeon HD 7790
IntroThe Radeon HD 6450 (OEM) uses a 40 nm design. AMD has clocked the core speed at 625 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this specific model. It features 160 SPUs as well as 8 Texture Address Units and 4 ROPs.Compare all of that to the Radeon HD 7790, which has a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7790 should theoretically be a lot faster than the Radeon HD 6450 (OEM) overall. (explain)
Texel RateThe Radeon HD 7790 will be a lot (more or less 1020%) better at AF than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe Radeon HD 7790 will be quite a bit (more or less 540%) better at AA than the Radeon HD 6450 (OEM), and will be able to handle higher resolutions without losing too much performance. (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 largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
