What the Xeon W3570 is
The Intel Xeon W3570 is a single-socket workstation processor from the March 2009 Bloomfield Xeon refresh. It runs four Nehalem cores at 3.2 GHz with Hyper-Threading for 8 threads, and Turbo Boost raises active cores to 3.466 GHz. Cache is 256 KB of L2 per core under a shared inclusive 8 MB L3 on a 45 nm process. Power is rated at 130 W on LGA 1366.
The W3570 sits one step below the range-topping W3580. It exists because workstation buyers wanted Core i7-965-class speed with ECC memory and workstation-board validation rather than a dual-socket server platform.
Socket and motherboard compatibility
The W3570 drops into LGA 1366 workstation boards with X58-class chipsets and a BIOS that recognizes the early-2009 Xeon steppings. It pairs with workstation boards qualified for Xeon W3500-series parts, not dual-socket server boards. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is ECC DDR3-800/1066/1333 in three channels, with UDIMMs or RDIMMs per board qualification.
The processor has no integrated graphics, so a discrete workstation GPU is required. PCIe slots hang off the X58 chipset.
Cooling should be a workstation tower cooler rated for a sustained 130 W, since rendering and simulation loads hold all four cores at boost for hours.
Upgrade paths
On LGA 1366 the upgrade is the Intel Xeon W3580 at 3.333 GHz for the fastest Bloomfield workstation chip, or the Intel Xeon W3565 and Intel Xeon W3550 for cheaper spare bins on the same board. Beyond LGA 1366 a move to a newer Xeon workstation platform needs a new board, memory and cooler.
