HD3870X2: Debunked and detailed (56k massacre)

I've read around a few of the threads here, and it seems that there is some general confusion and misinformation. I'm posting this thread to try and clear that up a bit.

First I will start off with power consumption. The 3870X2 consumes roughly 200W of power at peak load



I took this quote from Hardware Canucks (review written by SKYMTL)

Heat output (again taken from Hardware Canucks):

Second I want to clarify that This is indeed a PCIe 1.1a card and NOT PCIe 2.0. The two GPUs communicate over a bridge chip which uses only ~5w of power.

Detailed specs:
Note the GDDR3 use vs. GDDR4 on HD3870. AMD has allowed board partners to use GDDR4 on the PCB so we may see GDDR4 cards in the future.

The GPU's themselves have a frame buffer of 512Mb each. Whether this equates to 1Gb of total usable memory or not, I have yet to find out. Since in SLI and Crossfire you generally do NOT add the memory up I suspect that the 3870X2 actually has 512Mb of VRAM, instead of 1Gb.

Overclocking:
The cards themselves have two onboard BIOS's (but it still suffers from the 862 Mhz Core-lock), this means that if you were to flash your card to a new BIOS you would need to do it twice. I'm fairly certain AMD will release a new BIOS to fix the 862-locked Bug, which doesnt allow core overclocking past 862 Mhz. It has also been speculated that AMD tightened the timings on the GDDR3 (for performance gains) conversely this means less overclocking potential. SKYMTL once again found:

Please note that SKYMTL was reviewing an engineering sample, therefore certain details are subject to change, such as heat production. This should be used as an example.

The HD3870x2 interface is PCIe2 x16. The bridge chip which connects the 2 GPUs is PCIe1.1 .....

I imagine the day will come when the bridge may evolve to PCIe2 (or 3) but at 4 GB/s I don't think PCIe 1.1 x16 is quite bandwidth strarved ...

I look at it this way.

It's a fast card that is the most current with dx10.1 capability.
I could care less what it is, or how many cores and what the power consumption is. It performs at a point where it competes in the high end for a price that destroys the competition.

What more can one ask for?

My take on it (and the 9800GX2) would be not to make a rash purchase of either, maybe a wait and see approach would be better. Both cards may have their issues:
3870 x2: drivers
9800GX2: heat and power requirements

Well if the 9800GX2 is %30 faster than the ultra than it will be %20 faster than the 3870X2 with drivers I think the 3870X2 could make it
%5 - %10 but that just depends on the 9800GX2's real performance or if it's another phenom scenario

You could answer, each VPU has access to 512MB, so while the card has 1GB it really just acts like a very large 512MB card (for most things, you can actually use the memory cumulatively but you need apps that can do that, and most games are not coded to do so).
