Graphics Slugfest: ATI Radeon HD 4850 CF, HD 4870, HD 4870 CF vs. NVIDIA GeForce GTX 260, GTX 280

Starting off with ATI’s Radeon HD 4850 512MB cards, we take a look at ASUS’s own rendition of the Radeon HD 4850.

This particular model of theirs comes factory overclocked to 680MHz core and 1050MHz memory, up from the official specifications of 625MHz core and 993MHz memory.

Like most of the other cards out in the market (cards with after-market cooling solutions or custom PCBs are slowly streaming into the market), the ASUS EAH4850 TOP is based on the ATI reference design. The difference between cards from various manufacturers well.. actually lies with the different stickers placed on the plastic shroud of the heatsink only.

The Radeon HD 4850 employs the services of a single-slot heatsink fan solution for cooling.

The power consumption of a Radeon HD 4850 requires the implementation of only one PCI Express power connector.

 A metal backplate is placed at the back of the card to prevent excessive warping due to contact pressure between the heatsink and the RV770 core.


ASUS added a nice touch by packing everything in a nice black box with ‘gold’ lettering.
