In April this year, Intel announced a number of next generation products, including the 45-nanometer Nehalem micro-architecture and Tylersburg platform design. With the announcements came much talk about Intel’s upcoming X58 chipset, which at this time is still going through its initial sampling stages with motherboard manufacturers.

Today, we have the exclusive look at a full fledged X58 system. The new chipset will be the foundation Foxconn X58 MoboX58-Chipsatz, ICH10-R, 45 Nanometerfor Nehalem and Intel already indicated to us that the new platform will deliver a large boost in performance across all applications compared to currently available products.

With X58, end users will also start anew. Gone is the front-side bus, which is replaced by QuickPath on the X58. Those who are accustomed to overclocking their motherboards using the FSB, will have to start over and learn the new system. Similar to AMD’s HyperTransport, the QuickPath architecture will feature an integrated memory controller on the CPU and provide direct links between the CPU and system memory.Foxconn X58 MoboFoxconns Referenz-X58-Mainboard

Intel will launch the X58 chipset with the same ICH-10 family of southbridges currently used on its P45 platform. ICH-10 supplies up to four PCI Express x16 paths, of which two, are PCI Express 2.0 paths. Other possible combinations are: one x16 path, two x16 paths, four x8 paths, and one 16 path and two x8 paths.Because of QuickPath however, we’re able to realize far better performance with wide bandwidth and very low latency. According to Intel, Nehalem will initially come with a 20-bit wide 25.6 GB/sec. QuickPath link, which gives a theoretical 2x performance increase in bandwidth over the 1600MHz FSB currently available on the X48 platform.Foxconn X58 MoboBloomfield-LGA1366-Sockel

Memory support will come in the form of DD3 with support for 800MHz, 1066MHz and 1333MHz frequencies initially. Total bandwidth will be 32GB/sec. with support for up to 24GB of total system memory initially. X58 motherboards will provide up to 6 slots of memory but will require that the first slot (DIMM0) be populated.

Our sources indicated that Intel will release Bloomfield, the first of the Nehalem family at 3.2GHz, 2.93GHz and 2.66GHz and on an LGA1366-pin platform. Foxconn X58 MoboX58-ChipOur test system used the 2.93GHz, but we can confirm that significantly higher clock frequencies are available.

On hand today, we have Foxconn’s Renaissance X58 motherboard. Foxconn’s board will be the a reference board for many others, with minor differences here and there. On the board, we find the X58 MCH and the ICH10-R south bridge. Power connections include a standard ATX connector as well as an 8-pin CPU power connector.

Other features of the board are ultra-low resistance, crystal, ferrite salt-core inductors, and solid ultra-low SR capacitors. This board in particular uses a six-phase power circuit design but we can expect other manufacturers to introduce variances in the power department.

Foxconn X58 MoboBloomfield mit 2,9 GHzThe two blue PCIe slots on this board indicate that the slots are PCIe x16 2.0. There are also two black x16 1.0 slots. Other features include an Intelsil ISL6336 power management chip which supports the 6-phase switch power design, 2 FireWire IEEE 1394a ports provided by a TI TSB434B22A chip, and a Broadcom BCM5786KMLG chip for Gig-e support. Realtek’s ALC888S audio codec supports full 7.1 discrete analog output and optional Dolby Digital Live, DTS Connect, and Dolby Home Theater for real-time encoding of audio signals to an external processor or receiver.

The board also features vertical SATA connectors, although many manufacturers are now featuring angled slots for better cabling. Debugging LED lights and a clear CMOS button round out the rest of the board.

Foxconn X58 MoboCPU-Z zeigt massig Cache anSpeaking to other board manufacturers, X58 motherboards are about half-way through testing and validation and by the middle of this month, new revisions may be coming. Judging from what we were told, other board manufacturers already have board designs with features that are better than the Foxconn board we briefly looked at today. This isn’t really a problem since the board we looked at today is a typical reference design.

Unfortunately, NDAs prohibit us from publishing performance benchmarks, but those will definitely come later when Nehalem nears its launch.

Not sure why people are flipping out about "relearning" how to overclock.

Technically the FSB != bus speed. They do the same thing though when it comes to overclocking, bus speed times multiplier = final clock speed. I recently got an AMD based server, thought I was going to have a long time to relearn everything. Took me all of 5 minutes to realize they are the same :)

EDIT: I'd also suggest putting what you copied in quotes since you didn't say it ;)

Agreed! Guess Tom's never overclocked an AMD system before.

There are really only so many ways to slice the pie --- dividers, multipliers and clock. I've always wondered if they let the PR people name these "new things" just to confuse or buffalo us common folk.

Don't get me wrong, I'll get a Nehalem system as soon as I can afford it but it isn't because of all this PR. We've know for quite awhile that memory controllers on die are faster and increase available memory bandwidth. :screwy:
 
People are spoiled by how easy Core 2 is to overclock (myself included). It's gotten to the point where you can get a good overclock in 10 minutes nowadays.
 
Just forget fsb/bus speed as you know it. You will be focusing on CPU speed and dram speed. Quick Path is a system partly on die and partly off die. It's not clear how they will clock but from what I've seen, the IO part will be much like AMD, take advantage of the upper speed setting as it is fast. Matching the internal side may be the tricky part but I'm starting to think that internally, the interconnects run at CPU speed just as the Athlons did which is why with 3 banks of RAM you can get 32GB/Sec. I think these will be fun to OC and just watch those Dram throughputs rise as OCers start playing with them.

This.
The intel chips from the past 2 years have been incredibly easy to overclock.
 
The CPU Vcore has gotten even lower! I wonder how much difference there is in power consumption clock for clock.

They stated Nehalem uses roughly 10% more power for 50% more clock for clock performance.

The 50% increase in performance is only when you're doing benches / apps that can use all 4 cores / 8 threads. (Not very many)

Nehalem will also feature some better power saving features I believe or maybe just improved forms of what they have now. It's going to be an ownage architecture.
