Cores
Cores	8 Performance-cores and 12 Efficient-cores, with Hyper-Threading; codename Raptor Lake	Four cores with Hyper-Threading; eight simultaneous threads. PCStats confirms a locked CPU multiplier; base-clock overclocking is possible, so locked does not mean all overclocking is disabled.
Clocks
Clocks	P-core base 3.4 GHz, max turbo 5.5 GHz; E-core base 2.5 GHz, max turbo 4.3 GHz; Turbo Boost Max 3.0 5.6 GHz	Intel's product brief gives up to 2.93 GHz single-core Turbo Boost. Intel's 17 November 2008 sale notice names the 920 and confirms immediate system and boxed retail availability.

Memory support
Memory support	Up to DDR5 5600 MT/s or up to DDR4 3200 MT/s; 2 channels, up to 192 GB; ECC supported	Three channels of DDR3-1066 in Intel's exact-model product brief. A later Intel comparison chart incorrectly lists two channels; the original product brief is used here.
PCIe
PCIe	PCIe 5.0 and 4.0; 20 lanes (Up to 1x16+4, 2x8+4); DMI 4.0 x8	Intel's product brief describes X58 chipset PCIe 2.0 graphics connectivity, including two ×16 links. These are chipset connections, not CPU-integrated PCIe lanes. CPU-to-chipset QuickPath Interconnect runs at 4.8 GT/s for the 920.
