Advanced Vector Extensions
Advanced Vector Extensions (AVX) are extensions to the x86 instruction set architecture for microprocessors from Intel and Advanced Micro Devices (AMD). They were proposed by Intel in March 2008 and first supported by Intel with the Sandy Bridge processor shipping in Q1 2011 and later by AMD with the Bulldozer processor shipping in Q3 2011. AVX provides new features, new instructions and a new coding scheme. AVX2 (also known as Haswell New Instructions) expands most integer commands to 256 bits and introduces new instructions. They were first supported by Intel with the Haswell processor, which shipped in 2013. AVX-512 expands AVX to 512-bit support using a new EVEX prefix encoding proposed by Intel in July 2013 and first supported by Intel with the Knights Landing co-processor, which shipped in 2016. In conventional processors, AVX-512 was introduced with Skylake server and HEDT processors in 2017. Advanced Vector Extensions AVX uses sixteen YMM registers to perform a sin ...

Tick–tock Model
Tick–tock was a production model adopted in 2007 by chip manufacturer Intel. Under this model, every microarchitecture change (tock) was followed by a die shrink of the process technology (tick). It was replaced by the process–architecture–optimization model, which was announced in 2016 and is like a tick–tock cycle followed by an optimization phase. As a general engineering model, tick–tock is a model that refreshes one side of a binary system each release cycle. History Every "tick" represented a shrinking of the process technology of the previous microarchitecture (sometimes introducing new instructions, as with Broadwell, released in late 2014) and every "tock" designated a new microarchitecture. These occurred roughly every year to 18 months. In 2014, Intel created a " tock refresh" of a tock in the form of a smaller update to the microarchitecture not considered a new generation in and of itself. In March 2016, Intel announced in a Form 10-K report that it deprec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Process–architecture–optimization Model
Process–architecture–optimization is a development model for central processing units (CPUs) that Intel adopted in 2016. Under this three-phase (three-year) model, every microprocessor die shrink is followed by a microarchitecture change and then by one or more optimizations. It replaced the two-phase (two-year) tick–tock model that Intel adopted in 2006. The tick–tock model was no longer economically sustainable, according to Intel, because production of ever smaller dies becomes ever more costly.Tick Tock On The Rocks: Intel Delays 10nm, Adds 3rd Gen 14nm Core Product "Kaby Lake" AnandTech. 16 July 2015.

Zen 4
Zen 4 is the codename for a CPU microarchitecture by AMD, released on September 27, 2022. It is the successor to Zen 3 and uses TSMC's N5 process for CCDs. Zen 4 powers Ryzen 7000 mainstream desktop processors (codenamed "Raphael") and will be used in high-end mobile processors (codenamed "Dragon Range"), thin & light mobile processors (codenamed "Phoenix"), as well as Epyc 9004 server processors (codenamed "Genoa" and "Bergamo"). Features Like its predecessor, Zen 4 in its Desktop Ryzen variants features one or two Core Complex Dies (CCDs) built on TSMC's 5 nm process and one I/O die built on 6 nm. Previously, the I/O die on Zen 3 was built on GlobalFoundries' 14 nm process. Zen 4's I/O die includes integrated RDNA 2 graphics for the first time on any Zen architecture. Zen 4 marks the first utilization of the 5 nm process for x86-based desktop processors. On desktop and server platforms, Zen 4 has moved from DDR4 to DDR5 memory; DDR4 is not supported. Addit ...

Epyc
Epyc is a brand of multi-core x86-64 microprocessors designed and sold by AMD, based on the company's Zen microarchitecture. Introduced in June 2017, they are specifically targeted for the server and embedded system markets. Epyc processors share the same microarchitecture as their regular desktop-grade counterparts, but have enterprise-grade features such as higher core counts, more PCI Express lanes, support for larger amounts of RAM, and larger cache memory. They also support multi-chip and dual-socket system configurations by using the Infinity Fabric interconnect. History In March 2017, AMD announced plans to re-enter the server market with a platform based on the Zen microarchitecture, codenamed Naples, and officially revealed it under the brand name Epyc in May. That June, AMD officially launched Epyc 7001 series processors, offering up to 32 cores per socket, and enabling performance that allowed Epyc to be competitive with the competing Intel Xeon product line.

List Of Intel Codenames
Intel has historically named integrated circuit (IC) development projects after geographical names of towns, rivers or mountains near the location of the Intel facility responsible for the IC. Many of these are in the American West, particularly in Oregon (where most of Intel's CPU projects are designed; see Project code name#Famous code names, famous codenames). As Intel's development activities have expanded, this nomenclature has expanded to Israel and India, and some older codenames refer to celestial bodies. The following table lists known Intel codenames along with a brief explanation of their meaning and their likely namesake, and the year of their earliest known public appearance. Most processors after a certain date were named after cities that could be found on a map of the United States. This was done for trademark considerations. Banias was the last of the non-US city names. Gesher was renamed to Sandy Bridge to comply with the new rule. Dothan is a city both in Israel ...

VT-d
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance. In 2005 and 2006, both Intel (VT-x) and AMD (AMD-V) introduced limited hardware virtualization support that allowed simpler virtualization software but offered very few speed benefits. Greater hardware support, which allowed substantial speed improvements, came with later processor models. Software-based virtualization The following discussion focuses only on virtualization of the x86 architecture protected mode. In protected mode the operating system kernel runs at a higher privilege such as ring 0, and applications at a lower privilege such as ring 3. In software-based virtualization, a host OS has direct access to hardware while the guest OSs have limited acce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
