MSI Readies R4890 Cyclone, GPU Reaches 1.00 GHz

There are overclocked Radeon HD 4890 cards, and then there are overclocked Radeon HD 4890 cards. The difference between the two seems to be that the latter comprises of the "real" RV790OC-class SKU that runs at speeds in excess of 900 MHz, and offers a considerable overclocking headroom. The former, is mainly partners utilizing whatever headroom standard batches of RV790 offer, to come up with factory-overclocked settings that spice up specs-sheets. MSI joined the league of AIBs making a high-end Radeon HD 4890 accelerator, keeping the 1.00 GHz core frequency as a milestone.

Following Sapphire with its Atomic HD 4890 Vapor-X, MSI seems to be readying the R4890 Cyclone. This card uses a cooler similar to what some of its Radeon HD 4870 cousins sport, while using an elaborate, yet standard power circuitry. The cooler consists of a radial heatsink from which 2~4 8 mm heatpipes convey heat to two aluminum fin blocks that are arranged on either sides of the heatsink. A fan nucleates the heatsink, although it didn't make it to the picture. Over to the PCB, MSI does away with the lavish digital PWM circuitry on the reference PCB, and in its place, put a 5+2 phase standard DPAK power circuitry. What's fascinating about this PCB is that it carries the AMD brandmark, leading us to believe that AMD may have come up with a cost-saving PCB design that is available to its AIBs. The R4890 Cyclone is set for launch in the upcoming Computex 2009 event.

woah those are really thick heatpipes.... Judging from the amount of fin space that there is that fan is going to have to move quite a lot of air, though that looks like enough space for something like a 92mm fan.

The standard affair of voltage filtering is a better choice I believe over the digital phases since the digital phases tend to put out a lot of heat, as well as consuming much more power. Voltage control is obviously not as precise though.

92mmx25mm, my guess.

lol half naked PCB's always look fugly.

This looks like it will pwn any other manufacturer's 4890, the size of those heatpipes!!!!

i dont care what a card looks like aslong as it performs well, id take this over Asus Offerings and then even the Stock Cooler with the sticker (no need for that label when it comes off under heat anyway)

They took a stock Intel heatsink and made an overhaul with it. Looks nice!

Great card!I love the VRMs design.They look like they can handle a LOOOOT of current!
And the cooler looks great too.The best 4890 so far IMO!

Looks like a fantastic card, but with the 5+2 design does that do away with the Voltarra?

I wonder if the cooling system for the 5870 will look like this. I read somewhere they are going to try something different because of the 40nm die.

Will there be a aftermarket cooler that copies this design?

Partners associated with cooler companies like Zalman and Danger Den to sell graphics cards that have been OC'd.

still fits in the space of what your current card is and also supports a overall larger standard fan, not a blower type found on the stock units (they produce more noise than the standard fan anyway because they are designed for high speed, not best CFM to noise ratio around)
