The Intel Celeron P1053 was a server/workstation processor with 1 core, launched in February 2010, at an MSRP of $160. It is part of the Celeron lineup, using the Jasper Forest architecture with Socket 1366. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 2 threads. Celeron P1053 has 2 MB of L3 cache and operates at 1333 MHz. Intel is building the Celeron P1053 on a 45 nm production process, the transistor count is unknown. The multiplier is locked on Celeron P1053, which limits its overclocking capabilities.
With a TDP of 30 W, the Celeron P1053 consumes only little energy. Intel's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 800 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Celeron P1053 uses a PCI-Express Gen 2 connection. This processor lacks integrated graphics, you might need a graphics card.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability. Hardware virtualization is available on the Celeron P1053, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware.
