Common features of Ryzen 5000 desktop CPUs: Socket: AM4. All the CPUs support DDR4-3200 in dual-channel mode. All the CPUs support 24 PCIe 4.0 lanes. 4 of the lanes are reserved as link to the chipset. No integrated graphics. L1 cache: 64 KB per core (32 KB data + 32 KB instruction). L2 cache: 512 KB per core. Fabrication process: TSMC 7FF.
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]
As the first largely "ground up redesign" of the Zen CPU core since the architecture family's original release in early 2017 with Zen 1/Ryzen 1000, Zen 3 was a significant architectural improvement over its predecessors; having a very significant IPC increase of +19% over the prior Zen 2 architecture in addition to being capable of reaching higher clock speeds.
The original motivation for EFI came during early development of the first Intel–HP Itanium systems in the mid-1990s. BIOS limitations (such as 16-bit real mode, 1 MB addressable memory space, [7] assembly language programming, and PC AT hardware) had become too restrictive for the larger server platforms Itanium was targeting.
