Intel announced a number of next generation products earlier this year, including the 45-nanometer Nehalem micro-architecture and Tylersburg platform design. Here is the exclusive look at a full fledged X58 system. The new chipset will be the foundation X58-Chipset, ICH10-R, 45 Nanometer 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.
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.
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.
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.
The 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.
