Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 4850 512MB
IntroThe GeForce 8800 GT 1GB makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this specific card. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon HD 4850 512MB, which has GPU clock speed of 625 MHz, and 512 MB of GDDR3 RAM set to run at 993 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4850 512MB, in theory, should be a little bit faster than the GeForce 8800 GT 1GB in general. (explain)
Texel RateThe GeForce 8800 GT 1GB should be quite a bit (about 34%) better at AF than the Radeon HD 4850 512MB. (explain)
Pixel RateThe Radeon HD 4850 512MB is a bit (more or less 4%) more effective at anti-aliasing than the GeForce 8800 GT 1GB, and will be able to handle higher screen resolutions more effectively. (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 largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few 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.

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
