Introduction

The HIS Radeon HD 7770 iCooler goes through the Rage3D test suite today, and is largely a reference design card featuring AT 1Ghz Edition clocks and slightly non-reference cooler design. Price is around $129USD and is currently offered with a $15USD MIR, plus a free coupon for the CryEngine 3 based FPS game Nexuiz, based on the classic Quake title of the same name.

Our testing today will attempt to determine how the HIS Radeon HD 7770 iCooler differs from the reference AMD Radeon HD 7770 design, and we'll also look at how 7770's perform in CrossFire. The HIS box doesn't offer any stand out advantages over the reference design AMD Radeon HD 7770, so we'll have to look closely to see if there are any.
