Sapphire Toxic Radeon HD 4850 Review



The biggest problem of Radeon HD 4850 is that this card reaches high temperatures (70 degrees celcius) even in idle (i.e. not loaded). So manufacturers decided to discard the stock cooler in favour of a better and more efficient cooler. In these reviews, the Sapphire’s solution, the Radeon HD 4850 Toxic edition, is analyzed. This Radeon features a Zalman heatpipe fan, providing more efficient cooling, quieter operation and more headroom for performance tuning.


Due to the better cooling solution, frequencies have been overclocked:

Toxic Radeon HD 4850 has the following features:
– GPU: RV770
– stream processors: 800
– ROPs: 16
– transistors: 956M
– memory 512Mb / 256-bit
– core clock: 675MHz
– memory clock: 1100Mhz
– DirectX 10 / OpenGL 2.1


However, the Sapphire cooling solution is one of the noisiest cards under idle: around 40db. But this cooler does its job by keeping GPU temperature at least 20 degrees lower than a standard Radeon HD 4850.
