Sapphire 4850x2 2GB PCIe Graphics Card

In Detail

In Detail

Removing the main shroud was simple enough with only 8 tiny screws holding it to the main heatsinks and not the card itself. This should allow easy cleaning of the card should the heatsink get clogged with dust. Looking closer at the cooling, we see that there are numerous heatsinks separated according to the sections requiring cooling.

The main two heatsinks are attached via 2x4 screws from the back of the PCB which are also spring loaded ensuring an even mount. The remaining heatsinks for both the memory and the VRM's are attached with push pins and are easily removed.

The paste used on the GPU appeared to be very good with an MX2 type consistency rather some form of cement. Giving both even coverage as well as being very easy to remove is a major plus for both those wishing to continue with the stock cooling and the watercoolers out there.


Below we see the GDDR3 memory chips from Qimonda. While I would have liked to see DDR4 used, 2GB of that type would have no doubt increased the price of the card, so it appears Sapphire are satisfied with the bang per buck the Qimonda chips supply. Below right we see the Crossfire bridging chip which appeared to be glued onto the core itself as it would not budge regardless of heat applied.

Below are the numerous VRM's that are cooled by the aluminium heatinks both above and below the PCB. I do worry a little at the fact these heatsinks will not receive a fresh source of air and instead will rely on both the exhaust from the GPUs as well as ambient temps inside the case which may be counter productive.

Below we see the rear of the memory heatsink which has thermal pads in place of paste which should be adequate. The main GPU heatsinks have copper plates affixed to aluminium fins and as you can see from the picture below the correct amount of paste is used to good effect resulting in a near perfect mount.

Above right and below left we see the top and bottom VRM sinks are also adorned with thermal tape and below right we see the RV770 in all its naked glory.

So that's enough of the pretty pictures, time now to put this card to the test so head over the page to see our test setup and our overclocking results with the card.

Awesome card.

You should have also compared it to a Radeon HD 4870x2 to see the difference between the reds.

At 1600x1200, the GTX280 had double the frames of the 4850x2 in Crysis.

More driver problems?Quote

Very intresting, can't beleive I'm saying this but the high end ATI cards especialy the 4870x2 are getting more and more tempting and with this card I guess once the drivers are ironed out its likely to be good.

The GTX295 so far hasn't impressed me much, I'd like to have seen a single card solution as in a sucessor to the GTX280 however it's somewhat unfair to jump to conclusions just yet.

So I we will wait and see but judging by the previous 9800 GX2 wich I owned but wasn't overly impressed by, I don't like the layout idea of two cards linked with an internal SLI connector....I'm sure you will be able to give us the low down on that soon enough though any dates on a review webbo???

Good ReviewQuote

Due to it being the xmas period we won't have any GTX295's to report on just yet but as the impending release date is expected to be mid/late January I would expect to read a review around that time .Quote

will keep an eye outQuote

Meh... Noisy, bad driver support (worse than ATi itself... WOW) and about equal performance to the gtx280. Not to mention the fact that 2 cores on one card are harder to custom cool with air.

I was once hoping to go 4850x2, but now the only option I would remotely consider is another 4850 or a gtx260 216.

EDIT: good review though ^^Quote
