- GPU: RV790 @ 850MHZ / 55nm

Update:
Expreview has done some tests with the Radeon HD 4890 and FurMark:

The core temperature of Radeon HD 4890 achieves 83? with FurMark, and that of VRM climbs up to 110?, which is still within acceptable range. The fan running at nearly 2700RPM brings quite obvious noises. When running normal games, the fan speed ranges between 1800-2200RPM.
