AMD FX Zambezi Processors Compatible with ASUS AM3 Motherboards Using BIOS Update
AMD's upcoming FX series "Zambezi" desktop processors based on the "Bulldozer architecture are also expected to bring with them compatible motherboards, as AMD, on a number of occassions, stated that the chips will require a new socket (referred to as AM3+) and compatible chipset, and that the chips will be incompatible with existing AM3 socket and existing chipset. Information available with SweClockers points to the contrary.
According to the source, motherboard major ASUS is planning to provide support to AM3+ processors to some of its existing AM3 motherboards using mere BIOS updates. That's right, Zambezi will indeed be backwards compatible with AM3 and existing chipset, only what remains to be seen is if the processors will perform to their full potential and overclock well on existing platform. Amongst ASUS' Schindler's list are top of the line AM3 models, such as ROG Crosshair IV Formula and Extreme, M4A89TD PRO/USB3, and even AMD 890GX-based motherboards such as M4A89GTD PRO. The list also shows certain AM3+ motherboards that use dated chipsets such as 760G, probably the entry-level of ASUS' M5A series of motherboards.

Let's say a possiblity of an FX1000 and an FX1000+. Who knows.....
@Brandon
Same reasoning one would purchase an H55 over P55.....
You already know my take on the whole ordeal.
why buy something thats OLD tech with a new bios/CPU socket when you can get a 890G for maybe alittle more that has more features for around the same price?
for example, i ran my x6 thuban on my 780G/785G (i upgraded) board(s) for a while, and had zero performance loss (at stock!) doing so compared to my later bought 890FX board.
the new socket could be a cheap, excellent upgrade path for non OCers and people who just use mid range hardware/low end AM3+ CPU's
IF they would have not added extra pins and just did a bios update like with thuban then it would be super sweet.
Perfect analogy; dropping a corvette engine into a camaro frame with the same rear end tranny.
760G would be like shoving a corvette engine in a chevette
And in my scenario; the so called FX1000+ wouldn't be able to fit in the current AM3 boards due to the extra pin.
So "from a marketing perspective", you'r saying that an AMD FX1000+ CPU, would have the same pincount as an AMD FX1000 CPU?
Be cause the + model would (according to Asus), fit in the AM3+ ready motherboard (with the AM3 socket) - you see? It makes absolutely no sense.
But I guess that now Asus has made up their mind, calling AM3 motherboards with AM3 sockets AM3+ ready (AM3+ would be referring to a socket until now), they have changed the whole naming-scheme from AMD - since they refer to 939, AM2, AM3 etc. as a socket - has nothing to do with "marketing perspective".
As for mid-range and lower processors, I highly doubt the AM3+ platform will see anything other than AMD FX series processors. I suspect that like lga1366, AM3+ will be exclusively high-end, and that all mid-range will be powered by the Llano A-series APUs, and the low-end/ULV powered by the Brazos C/E-series APUs. Could that change? Sure. But if it does, any slower AM3+ chips will certainly not get the FX moniker. Here's a list of the upcoming mid-range products.
Unsure what it would change or be. Again all speculation on my part and I think i might be putting too much thought into this.
The 990FX chipset should include HTT3.1, PCI-Express 3.0 (I think), and TurboCore 2.0 support. I suspect the latter to be the most relevant in AMDs decision to exclude AM3 boards, as I don't believe per-core voltage modification is supported (and if it is, likely not how the Zambezi chips require it). In the past, AMD chips never had much of a performance difference from HTT 1.0 -> 2.0 and so on, but maybe it will be more important for Zambezi?
Unfortunately, I don't see native USB3 support coming (I think the Llano chipset will be the only one to see that), but I do foresee many new motherboards being released supporting the UEFI standard over the BIOS.
The question I have for some of you all is that if the reason is money, why would Asus be making Zambezi compatible BIOSes for current motherboards? A stronger argument is why would they announce them now, potentially hurting future motherboard sales, instead of just silently releasing updates once they've become satisfied by AM3+ motherboard profits?
/rhetorical thoughts Exactly what i am questioning as well.
