What the Pentium D 920 is
The Intel Pentium D 920 is a 2.8 GHz dual-core desktop processor from January 2006. It runs two NetBurst cores at 2.8 GHz with no Hyper-Threading, so 2 cores give 2 threads. Cache is 4 MB of L2 as two 2 MB dies on a 65 nm process. Power is rated at 95 W on LGA 775.
The 920 opened the Presler 9xx line on an 800 MT/s bus with a 14x multiplier at about 241 dollars launch price. It exists because buyers wanted the first 65 nm dual cores with virtualization support at 2.8 GHz.
Socket and motherboard compatibility
The 920 drops into LGA 775 boards with DDR2 memory and a BIOS that lists early Presler dual cores, such as 945 boards. It pairs with mainstream chipsets contemporary with Presler. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 through the board chipset in two channels.
An 800 MT/s front side bus ties the CPU to the chipset. PCIe slots hang off the chipset.
Cooling is any 95 W rated LGA 775 heatsink on the 72 mm mount.
Upgrade paths
On LGA 775 the upgrade is the Pentium D 930 at 3 GHz with the same 4 MB cache, or the Intel Pentium D 915 at 2.8 GHz for a lower cost without virtualization. Beyond LGA 775 a move to a newer platform needs a new board and memory.
