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] Many or most Xeons subsequent to this support VT-d.
It has 1331 pin slots and is the first from AMD to support DDR4 memory as well as achieve unified compatibility between high-end CPUs (previously using Socket AM3+) and AMD's lower-end APUs (on various other sockets). [3] [4] In 2017, AMD made a commitment to using the AM4 platform with socket 1331 until 2020.
Both low-power APU versions feature two Bobcat x86 cores and fully support DirectX11, DirectCompute (Microsoft programming interface for GPU computing) and OpenCL (cross-platform programming interface standard for multi-core x86 and accelerated GPU computing). Both also include UVD dedicated hardware acceleration for HD video including 1080p ...
Socket 939 (also known as Socket AM1) is a CPU socket released by AMD in June 2004 to supersede the previous Socket 754 for Athlon 64 processors. Socket 939 was succeeded by Socket AM2 in May 2006. It was the second socket designed for AMD's AMD64 range of processors.
All models support DDR5-5600 or LPDDR5X-7500 in 128-bit "dual-channel" mode. CPU uses Zen4 cores (Phoenix) or a combination of Zen4 and Zen4c cores (Phoenix2). GPU uses the RDNA 3 (Navi 3) architecture. Some models include first generation Ryzen AI NPU (XDNA). All models support AVX-512 using a half-width 256-bit FPU. PCIe 4.0 support.
AM3+ CPUs are not mechanically compatible with AM3 sockets as AM3+ CPUs have an additional pin that the AM3 socket can not accommodate. Another issue is the use of the sideband temperature sensor interface for reading the temperature from the CPU. Therefore, some CPU PWM fan headers may only run at full speed.
Socket 462 of an 800 MHz Athlon CPU. Initially launched with 100 MHz FSB support in the earliest chipsets it evolved stepwise to faster 200 MHz FSB while maintaining pin compatibility throughout its lifetime. However, clock, timing, BIOS and voltage differences restrict compatibility between older chipsets and later processors. [2]
