Compare any two graphics cards:
GeForce GTS 150 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTS 150 features core speeds of 740 MHz on the GPU, and 500 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs as well as 64 TAUs and 16 ROPs.Compare all that to the Radeon HD 6450 (OEM) 1GB, which has a GPU core clock speed of 750 MHz, and 1024 MB of GDDR5 memory running at 900 MHz through a 64-bit bus. It also is made up of 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 150, in theory, should be a small bit faster than the Radeon HD 6450 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTS 150 is much (about 689%) better at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTS 150 is quite a bit (approximately 295%) better at AA than the Radeon HD 6450 (OEM) 1GB, and able to handle higher screen 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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
