NVIDIA Preparing nForce 980a SLI, Identical to Predecessor
NVIDIA is planning a new high-end desktop chipset for the AMD processor platform: the nForce 980a SLI. The news validates some of the earliest roadmap slides of ASUS leaked to the media, showing a certain M4N82 Deluxe to feature the said chipset according to the specifications sheet. The chipset is built to feature on newer motherboards supporting the AM3 socket and DDR3 memory, though the one from ASUS supports DDR2 memory only, with no mention of a DDR3-supportive motherboard from the company.
VR-Zone juiced some more information about this new chipset, which suggests that the nForce 980a could be merely a re-branded nForce 780a SLI. Earlier reports also suggested the possibility of the 780a SLI successor to support the Advanced Clock Calibration (ACC) feature that enhances overclocking the CPU using AMD's Overdrive software. With the 980a, NVIDIA will replace the markings on the package from "NF780A-SLI-N-A2" to "NF980A-SLI-A2". The company has also reportedly issued a notice to its partners:

The NVIDIA nForce 980a SLI SPP is an enthusiast-class high performance interface to AMD AM3 CPUs. It is RoHS-compliant. It includes 2×16 PCI Express 2.0 lanes (also configurable as 1 x16, 2 x8) and 3×1 PCI Express 1.0 lanes, 12 USB ports, six SATA ports, and single GigE. To ensure timely availability and flexibility, we encourage customers to qualify and release products using the NVIDIA nForce 980a SLI SPP.The chipset will be available to motherboard manufacturers starting from March.

Has nVidia completely given up on releasing new products that are actually new.
Why would you buy a 980a when you already have a 780a other than the change in name? It's rather ridiculous.
With 780a SLI, what NV did was it made an SPP + MCP chip that gives out only 16 lanes in all to graphics, to which the BR-03 is connected, this BR-03 gives out 32 lanes in all: either x16, x16, NC or x16, x8, x8. The "southbridge" you see on 780a SLI motherboards is actually the BR-03 chip, not an MCP. Now just remove the BR-03 chip from the equation, and you have yourself the nForce 750a SLI, where the SPP itself splits lanes into x8, x8 for two cards.
For the level of performance Phenom X4 processors ended up with, NV felt the 780a was enough. If you're buying three GTX 285 or even three GTX 260, you probably have enough dough for an Intel platform, thinks NVIDIA.
When you look at the 790i/780i vs. the 780a in terms of bandwidth available to the cards:
790i/780 = PCI-E 2.0 x16/x8/x16 = PCI-E 1.0 x32/x16/x32
780a = PCI-E 2.0 x16/x8/x8 = PCI-E 1.1 x32/x16/x16
I don't think there is any graphics card that is Tri-SLI capable, that also benefits from anything higher than PCI-E 2.0 x8.
i have had 780a and 780i and IMO 780a is a million times more refined than 780i
I'm waiting for NVIDIA to announce a name change to VIDIAN just because NVIDIA was around too long.
In all honesty, I think it is actually a smart move to just keep the top and mid-range products of the previous generation around to fill the mid-range and low-end of the current generation. Why spend money developing and releasing products that replace existing products with the same performance? But they don't have to rename them.
Good God people! Doesn't anyone check the specification?
I realize that the article was written a month before the release of the 980a chipset, but do reporters ever check the fact before posting roomers as fact? People go check the facts before you bellyache on the forum. The 980a is NOT a rebranding of 780a.
980a provide support for DDR3, DDR2, DDR1, AM3, AM2+, AM2, PCIE 35-lanes.
780a provides support for DDR2, AM2+ PCIE 35-lanes
AM3 processors supports DDR3 - AM2 and AM2+ do not!
Granted - Nvidia did not up the PCIE lanes to 3-x16 (or more) which some hard core gamers might want to complain about, but most of us can do just fine with dual geforce 295 (@2-x16) or less.
Why ASUS made a 980a mother board (M4N82 Deluxe) using DDR2 is such a waste. There is no reason to put a AM3 processor in it. And if you have an AM2 or AM2+ processor, you might as well use it on a 780a motherboard.
Running DDR2 at 1066 is only supported with 1 memory stick per channel (I.E 64-bit vs 128-bit).
I'll bet the motherboard will perform better running memory at 800 in dual channel mode vs 1066 in single channel mode.
