[Fudzilla]ATI preparing a revision to the HD3870X2

ATI is working on a new revision of its Radeon HD 3870 X2 card; and if all goes well, you should be able to get one by the middle of Q2, if not even earlier.

The new card will have an updated PLX Bridge chip that will support PCIe 2.0 and at the same time, ATI is trying to shorten the PCB and add GDDR4 to the card. The current Radeon 3870 X2 has a PLX chip that supports PCIe 1.1 communication and, obviously, a new card should have some better results with the faster inter-chip communication.

The RV670 chips will upgrade to revision 12 and this probably means higher frequencies and more performance. The current Radeon 3870 X2 dual chip cards come with RV670 chips' Revision 11.
Looks like the HD3870X2 is going to get even better now. Though it kinda sucks for those who already bought one.

This is why you should never run out and buy BRAND NEW technology. It is going to be constantly evoling. The same goes for the new 45nm Intel CPU's.

But how would they evolve if people weren't there to buy the first one??? And if you waited till you felt they had evolved as far as they can, you would never buy hardware, cause it's always evolving.


But anyway, that's sweet, would love to see GDDR4 on here and higher clock speeds.

I don't understand how it is obvious that PCIe 2.0 would do better for results?

i didn't think that 16x PCIe was even CLOSE to bandwitch issues, this shouldn't make much difference

Well if you think about it, that x16 slot has to be split up for the two cards. so x8 each. A very very slight bottleneck, but it's still there.

I guess we'll have to wait and see when they bench the 2.0's

This is cool, but can't they keep it for the 4000 series?

That's awesome. It will have lower power consumption with the GDDR4 as well.......I wonder how much performance gains will be had with the revised core logic......

BTW there is definitely a difference between 8x and 16x..........just because the card's the theoretical bandwidth output doesn't match the bus's doesn't mean that there wont' be any performance gains.

The PCIe chip is used for inter-chip (aka intra-video card) communication. PCIe is duplexed so the cards should be using the same link to each other.
