Compare any two graphics cards:
GeForce GTX 650 Ti vs Radeon HD 3850 256MB
IntroThe GeForce GTX 650 Ti makes use of a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this card. It features 768 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 3850 256MB, which uses a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 memory is set to run at a frequency of 828 MHz on this particular card. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 650 Ti should in theory be much superior to the Radeon HD 3850 256MB overall. (explain)
Texel RateThe GeForce GTX 650 Ti is quite a bit (approximately 456%) more effective at AF than the Radeon HD 3850 256MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 650 Ti is a better choice, 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: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
