The HD5850 has always provided an excellent compromise between price and performance. Compared to its bigger brother, the HD5870, which shares the same core, all the main features are present with the main difference being 8 less texture units, 160 shader cores disabled and a slightly lower clock speed on the former. The question has always been if the £100/$100 price difference is worth the performance difference so the review today will focus on this.

ASUS are renowned for the extras that they bundle with their graphics card offering, namely their voltage tweak utility, which we previously saw in their HD5870 review. The tool is of added benefit to the HD5850 by not only giving ASUS an advantage over other manufacturers but also unlocking its full potential to compete with HD5870. Coupled with a custom DirectCU cooler and a mild overclock, ASUS aim to deliver superior performance without the inconvenience of heat and noise.
