Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 4850 512MB
IntroThe GeForce 8800 GT 1GB comes with a clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and uses a 65 nm design. It is made up of 112 SPUs, 56 TAUs, and 16 ROPs.Compare all that to the Radeon HD 4850 512MB, which comes with a clock frequency of 625 MHz and a GDDR3 memory frequency of 993 MHz. It also features a 256-bit memory bus, and makes use of a 55 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4850 512MB, in theory, should be a small bit faster than the GeForce 8800 GT 1GB in general. (explain)
Texel RateThe GeForce 8800 GT 1GB will be much (more or less 34%) more effective at AF than the Radeon HD 4850 512MB. (explain)
Pixel RateThe Radeon HD 4850 512MB is a little bit (approximately 4%) better at AA than the GeForce 8800 GT 1GB, and will be capable of handling higher screen resolutions without slowing down too much. (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 MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

One Response to “GeForce 8800 GT 1GB vs Radeon HD 4850 512MB”Thats imposible , i got 1 hd4850 512 mb 256 bit and i can play the famous game dishonored at 30-35 at very low / 1024/768 . Now i can play with this gt 8800 1gb 256 bits at very high at full rezolution with 35-40 . You are wrong guys
