The 3D rendering speed of the Radeon HD 4850 is excellent. Compared to its predecessor, the HD 3850, we measured up to 47.5% more overall performance. MSI does not offer an overclocked model. Rather, the card runs at default clock rates of 625 MHz for the GPU and 1,986 MHz for the memory. The graphics chip supports DirectX 10.1, and the memory subsystem includes 512 MB of GDDR3.
AMD has done a lot with the price of the Radeon HD 4850. At just $179, it puts the GeForce 8800 GTX, 8800 GTS 512, and 9800 GTX under serious pressure, and is responsible for the serious price reductions of the Radeon HD 3850, HD 3870 and GeForce 8800 GT.
Many gamers are waiting with bated breath for the 4850 sporting a two-slot fan, as the one-slot version is plenty quiet, but heats the interior of the PC considerably. If you do not have good case ventilation, you will want to change this or use the HD 4870 instead.
AMD has kept the fan speed very low, which reduces the volume while sitting on the Windows desktop to 36.3 dB(A), but the graphics chip (GPU) reaches temperatures of at least 78 degrees C. This affects the other components in the system, because the default fan only circulates the air within the case. In 3D mode, the GPU temperature increases to 83 or 85 degrees C, and anything requires the fan to kick into high gear.
The power consumption of the full system using the Radeon HD 4850 at idle is 122 watts. Under full 3D load, it can be as high as 237 watts.
