Sapphire Vapor-X Radeon HD 4850

Sapphire recently released a new flagship in the Radeon HD4800 series (the HD4890), but they have also been busy refreshing some of the existing model numbers. The HD4850 and HD4870 have been on the shelf for a while now, but Sapphire has integrated a few electrical, aesthetic, and cooling updates in to the designs and have released them as their “Vapor-X” series of cards.

While you may get better out of the box performance with some of the factory overclocked cards, the Sapphire Vapor-X Radeon HD4850 512MB graphics card allows plenty of opportunity for you to do it yourself. The stock speeds are exactly what you might expect for a Radeon HD4850, but that isn’t what this new series of cards is all about.

The biggest selling point may be that this card runs cool, quiet, and it is relatively energy efficient. Sapphire has made a few electrical tweaks, as well as developing a new cooler, that give you all the performance of a Radeon HD4850 without as much heat, noise, or electricity consumption. Couple these improvements with a more compact PCB and you have a card that would work well in a typical tower chassis, as well as many small form factor or HTPC setups.
