First of all, that is only partly true. To answer your question, the only difference between what you call the fused C2Ds and what you would call the real C2Q is that there is some latency between the set of the two cores because they have to communicate with each other, also, each set of two cores share 4MB of L2 Cache, there isn't 8MB of shared L2 Cache, that's why they call it 2x4MB and not 8MB shared. But with the newer Q9xxx series, it's a real quad-core and there is 12MB of shared L2 Cache, which means lower latency first of all, and more memory shared among all cores.

Not necessarily, especially in times like now when AMD is in such a cash crunch that they can't dedicate lots of funding into R&D. Why not ride on the success of the RV670? Also by letting Asus to create the 3850X2, that's one less thing AMD has to allocate funding for, yet the consumer will greatly benefit from the performance and increased AMD HD3000 series portfolio. IMO, these cards are definitely NOT a fail.

$300 is not worth it for this card considering that the G92 8800GTS beats two HD3850's in crossfire and pretty much ties the HD3870X2 for only $240.

These Dual cards are perfect for those who:
1: Have a lot of money and want the absolute best
2: Want Quad Crossfire/SLI
3: Only have 1 PCI-E slot or have the other brand chipset and can't do normal Crossfire/SLI.
4: There's always a market for someone

"shut up Steve, go sit in the corner"

"lets take a 3850 and slap another core on it and call it a new card!"


Seems right now, both Nvidia and ATI are throwing out some slightly tweaked G92 / RV(670 is it?), until the new stuff later in the year.

wasn't this the same tactic that 3dfx used? don't make one core faster just add more cores to it.

are you sure about that with the cache. cpuz shows it as 2x6144 Kbytes. not 12Mb.

3DFX did make a Quad GPU card, the Voodoo 6000, which subsequently lost out to cards like the single GPU Radeon 7500 and GeForce 2 cards. Which just goes to show, invest your resources in designing a powerful single GPU and it will likely be able to beat the competition's multi GPU setup.

Anyone remember the 2600XT X2?

I think there was a x1600 something X2 and a X1900 something X2 also.
