Each tile's memory controller provides two channels of DDR5 ECC supporting 4 DIMMs (2 per channel) and 1 TB of memory with a maximum of 8 channels, 16 DIMMs, and 4 TB memory across 4 tiles [30] A tile provides up to 32 PCIe 5.0 lanes, but one of the eight PCIe controllers of a CPU is usually reserved for DMI , resulting in a maximum of 112 non ...
In computing, an input–output memory management unit ( IOMMU) is a memory management unit (MMU) connecting a direct-memory-access –capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses, the IOMMU maps device-visible virtual addresses (also called ...
The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2]
System Controller Hub. System Controller Hub ( SCH) is a family of Intel microchips employed in chipsets for low-power Atom -based platforms. Its architecture is consistent with the Intel Hub Architecture but combines the traditional northbridge and southbridge functions into a single microchip .
v3.0 at 8 GT/s (×4 4 GB/s) v4.0 at 16 GT/s (×8 16 GB/s) Style. Serial. In computing, Direct Media Interface ( DMI) is Intel 's proprietary link between the northbridge (or CPU) and southbridge (e.g. Platform Controller Hub family) chipset on a computer motherboard. [1] It was first used between the 9xx chipsets and the ICH6, released in 2004.
I/O Acceleration Technology. I/O Acceleration Technology ( I/OAT) is a DMA engine (an embedded DMA controller) by Intel bundled with high-end server motherboards, that offloads memory copies from the main processor by performing direct memory accesses (DMA). It is typically used for accelerating network traffic, but supports any kind of copy.
Intel Graphics Technology. Intel Graphics Technology [4] ( GT) [a] is the collective name for a series of integrated graphics processors (IGPs) produced by Intel that are manufactured on the same package or die as the central processing unit (CPU). It was first introduced in 2010 as Intel HD Graphics and renamed in 2017 as Intel UHD Graphics .
Max. CPU clock rate. Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is a die shrink / tick of the Sandy Bridge microarchitecture ). [1]
