$589 / $309Intel 800-Series Platform, Supported By The New LGA 1851 Socket
With the chips and their performance out of the way, the next topic that we have to discuss is the platform. For its Arrow Lake lineup, Intel is introducing a brand new socket which ends the reign of the LGA 1700 series after a little over three years. The new socket from now onward will be LGA 1851 and this will be first featured on the new 800-series motherboards.
The 800-series chipsets will include several SKUs but the one we are getting today is the top-tier Z890. This platform offers a total of 48 PCIe lanes of which 20 are PCIe Gen 5.0 and these come from both the CPU and the PCH. The Z890 PCH features up to 24 PCIe 4.0 lanes, up to 4 eSPI, up to 10 USB 3.2 ports including 5 20G, 10 10G, and 10 5G options, up to 14 USB 2.0 links & up to 8 SATA III links.
The new platform is further enriched with the latest features which include:
Integrated I/O:
- Up To 2 Thunderbolt 4 ports
- Intel Killer Wi-Fi 6E (Gig+)
- Bluetooth 5.3 (LE)
- 1 GbE
Discrete I/O:
- Up To 4 Thunderbolt 5 ports
- Intel Killer Wi-Fi 7 (5 Gig)
- Bluetooth 5.4 (LE)
- 2.5 GbE
In terms of memory support, the new Z890 motherboards will offer up to DDR5-6400 (native) capabilities and expanded speeds over 8000 MT/s with XMP. The platform will support up to 48 GB DIMMs in the dual-channel mode for up to 192 GB capacities in UDIMM, CUDIMM, SODIMM, and CSODIMM flavors.
Lots of Goodies For Overclockers!
Finally, we have the new overclocking goodness which comes in the form of new functionalities for tuners with fine grain control.
These features include:
- Granular core clock - Top turbo frequency in 16.6 MHz steps for P-Cores and E-Cores
- Dual base clock - Run an independent BCLK for SOC and compute tiles
- Tile-to-Tile & fabric OC - Can apply a static/BIOS ratio and supports dynamic ratio changes for fabric
- DLVR bypass - Bypass the internal voltage management using an external supply for extreme OC
- Intel eXtreme tuning utility - New features including automated OC enhancements
- Memory overclocking - New memory controller supports new XMP and CUDIMM DDR5
- P & E-core overclocking - P-core per-core V/f control, and E-Core per cluster V/f control
- Low-temperature overvolting - Increasingly bypass voltage limits as the chip gets colder
The cooler operation of the chips also provides higher headroom for overclockers. As for the TJmax, Arrow Lake-S "Core Ultra 200S" will have a peak operating temperature of 105C.
