Now what concerns the cooler. The cooling system is exactly as in RADEON HD 3850. The base of the cooler has changed (to fit the new layout of memory chips), and the heat sink is now entirely made of copper, so the card is a tad heavier.

The operation principle is the same: a turbine drives air through the heat sink. Con: hot air is not thrown out of a system unit, it stays inside. Pro #1: narrow single-slot cooler. Pro #2: quiet cooling system.

Unfortunately, RivaTuner does not support the new RV770 family yet, so we don't have monitoring results.


As the reference card comes as OEM, we cannot describe its bundle. And the basic bundle must include the following items: User's Manual, CD with drivers and utilities, a DVI-to-VGA adapter, a CrossFire bridge, a DVI-to-HMDI adapter, a component output adapter (TV-out), and external power splitters. And now let's see what other accessories are bundled with each card.


A basic bundle, except for the external power splitter. However, all modern PSUs offer 6-pin cables. The bundle has a bonus - a screwdriver with several tips and a flashlight.

Gigabyte GV-R485-512H-B 512MB

A basic bundle.

MSI R4850-72D512 512MB

In this case we see the basic bundle minus an external power splitter. Plus various MSI programs (overclocking utilities, BIOS updaters, etc).

PowerColor RADEON HD 4850 512MB

A basic bundle plus CyberLink software.
