Before the Coffee Lake architecture, most Xeon and all desktop and mobile Core i3 and i7 supported hyper-threading while only dual-core mobile i5's supported it. Post Coffee Lake, increased core counts meant hyper-threading is not needed for Core i3, as it then replaced the i5 with four physical cores on the desktop platform. Core i7, on the ...
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]
Zen 3 is the last microarchitecture before AMD switched to DDR5 memory and new sockets, which are AM5 for the desktop "Ryzen" chips alongside SP5 and SP6 for the EPYC server platform and sTRX8. [3] According to AMD, Zen 3 has a 19% higher instructions per cycle (IPC) on average than Zen 2.
Ryzen uses the "Zen" CPU microarchitecture, a redesign that returned AMD to the high-end CPU market after a decade of near-total absence since 2006. [6] AMD's primary competitor, Intel, had largely dominated this market segment starting from the 2006 release of their Core microarchitecture and the Core 2 Duo. [7]
AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation. AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008. [2] A wider version of AES-NI, AVX-512 Vector AES instructions (VAES), is found in AVX-512. [3]
An Intel Bloomfield processor. Bloomfield and Gainestown introduced a number of notable features for the first time in any Mac processors: Integrated memory controllers (with on-die DMI or QPI). Simultaneous multithreading (branded as Hyper-threading). Full support for the SSE4 instruction set (SSE4.2). Support for Intel Turbo Boost.
