nVidia nForce3 Chipset
Anand Shimpi will be talking much more about chipsets at launch, but since this is our first real look at the nForce3 chipset, we should talk a bit about key features. One of the most exciting, and also controversial, features of the Opteron/Athlon64 is AMD’s decision to include the memory controller on the CPU. There are tremendous potential speed advantages to this solution, but the complexity of manufacturing also increases significantly. This can dramatically lower yields, which are becoming increasingly important in a competitive CPU environment.nVidia’s nForce3 PRO is the only one of the Opteron/nForce3 chipsets in a single-chip package. Both VIA K8T800 and SiS755 will use the more familiar Northbridge/Southbridge arrangement. Key features for nForce3 PRO are:
We also see nVidia including some more familiar options, like the much-talked-about AMD Hypertransport first used in their nForce chipset, 6 USB 2.0 ports, and AC’97 with an SPDIF interface. Undoubtedly, the consumer versions of nForce3 will have even more features, but as a base chipset, nForce 3 is certainly competitive with Intel’s latest 875/865 chipsets.
- Single-Chip Solution — Revolutionary single-chip solution designed for the AMD Opteron CPU enables higher-quality, full-featured motherboards and delivers maximum performance with the lowest latency. The single-chip design also means less power consumption and less heat dissipation.
- Dual-Channel DDR400 Memory — Our reference board includes full support for Dual-Channel DDR ECC memory, and the Athlon64 version will also support non-ECC memory
- Integrated SATA/IDE Raid — Provides support for RAID 0, RAID 1, and RAID 0+1, enabling the highest disk data transfer rates for highest system and application performance, and the highest performance fault tolerant solution for maximum data integrity. NVIDIA RAID supports both SATA and ATA-133 disk controller standards.
- Enterprise-Class Networking — Delivers the required manageability features required by IT professions while maintaining the highest level of reliability, quality, and performance. Also delivers the highest throughput for network transfers and lower CPU utilization, resulting in lower total cost of ownership.
- 64-Bit Architecture — NVIDIA nForce3 Pro provides advanced processing capabilities and system innovations for the new 64-bit AMD processor architecture.
More information on nForce3 PRO is available at www.nvidia.com/page/nforce3.html.

I'd like to see some benchmarks where the opteron's advanatges could really be used:
1) some database or rendering benchmarks on workstations with more than 4GB of ram and large worksets that use more that 4G.
x86/pentium cpus have to use a segmented memory architecture becuase of the 4G address space, so it's kind of like swapping, and is alot slower than direct access that a 64 bit chip has.
2) how about some 64bit benchmarks on linux?
Quake3 runs natively on linux, why have I seen none? Laziness, or lack of technical knowledge?

Intel will have a 100w toaster oven to compete with AMD, that and probably SSE3 just to make everyone recompile and distance AMD again. That and of course a 1mb cache.Isn't that Xenon have a 1MB but L3? That means it has 1.5MB, and still lags.

Impressive cpu but it would've been nice to see how much of an improvement the extra 200mhz made...unless I'm missing something here...does anyone have a link that has a 1.8ghz opteron and a 9800 pro?Anonymous User - Friday, September 5, 2003 - link
Minor correction on page 2. nForce was the first AMD based board to use HyperTransport IIRC, not the nForce2Anonymous User - Friday, September 5, 2003 - link
Hrm, as I am sure Intel has samples of the Opteron CPUs, its kinda surprising to see them not have anything significant ready to counter.. I highly doubt the Prescott will perform more than 10-20% better than the fastest Northwood P4.. If can't, then it'll definitely be slower than these new Opterons.. Let's see if Intel can counter, or else its gonna be a bloodshed for them..Evan Lieb - Friday, September 5, 2003 - link
#13,Because CPU supply right now is EXTREMELY tight. Wait until the end of the month for more info on dual Opteron/A64 performance numbers. :)
Take care,
Evan

This is all very exciting stuff for AMD fans...but as a dually enthusiast, I wonder why there are no benchmarking stats for a top-end Athlon MP workstation/gaming solution? Why include the Xeon dually and not an Athlon dually? Certainly in the Content Creation areas we'd see a landslide for the good old dual MP mobos...imagine a 150 MHz FSB PC3200 2.6 GHz overclocked Barton 2500+ dually w/ the Radeon 9800...best price/performance ever IMHO...Wesley Fink - Friday, September 5, 2003 - link
As Anand and many others have been saying for months, Athlon64 is supposed to be single-channel Socket 754 and able to use unbuffered memory. Since the rumored FX Enthusiast version is said to be Socket 940 it will fit Opteron boards like the Asus SK8N, so will be dual-channel. Thus far the only ones I have seen from these aleady RELEASED motherboards have required registered memory - ECC or non-ECC - but that could of course change with later releases.tazdevl - Thursday, September 4, 2003 - link
Also, I was under the impression that the socket 939/940 boards will support unbuffered memory.tazdevl - Thursday, September 4, 2003 - link
I'd like to see a temp comparison between all the CPUs.
