Compare any two graphics cards:
GeForce GTX 650 Ti vs Radeon HD 4850 1GB
IntroThe GeForce GTX 650 Ti comes with core clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare that to the Radeon HD 4850 1GB, which comes with a clock speed of 625 MHz and a GDDR4 memory frequency of 993 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It is made up of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe GeForce GTX 650 Ti should theoretically perform a lot faster than the Radeon HD 4850 1GB in general. (explain)
Texel RateThe GeForce GTX 650 Ti will be a lot (about 138%) faster with regards to texture filtering than the Radeon HD 4850 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 650 Ti is the winner, by a large margin. (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 data (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
