Zen 5
Zen 5 (''"Nirvana"'') is the name for a CPU microarchitecture by AMD, shown on their roadmap in May 2022, launched for mobile in July 2024 and for desktop in August 2024. It is the successor to Zen 4 and is currently fabricated on TSMC's 5 nm process, N4P process. Zen 5 is also planned to be fabricated on the 3 nm process, N3E process in the future. The Zen 5 microarchitecture powers Ryzen 9000 series desktop processors (codenamed "Granite Ridge"), Epyc 9005 server processors (codenamed "Turin"), and Ryzen AI 300 thin and light mobile processors (codenamed "Strix Point"). Background Zen 5 was first officially mentioned during AMD's ''Ryzen Processors: One Year Later'' presentation on April 9, 2018. A roadmap shown during AMD's Financial Analyst Day on June 9, 2022 confirmed that Zen 5 and Zen 5c would be launching in 3nm and 4nm variants in 2024. The earliest details on the Zen 5 architecture promised a "re-pipelined front end and wide issue" with "integrated AI and Ma ...

FMA Instruction Set
The FMA instruction set is an extension to the 128- and 256-bit Streaming SIMD Extensions instructions in the x86 microprocessor instruction set to perform fused multiply–add (FMA) operations. There are two variants: * FMA4 is supported in AMD processors starting with the Bulldozer architecture. FMA4 was performed in hardware before FMA3 was. Support for FMA4 has been removed since Zen 1. * FMA3 is supported in AMD processors starting with the Piledriver architecture and Intel starting with Haswell processors and Broadwell processors since 2014. Instructions FMA3 and FMA4 instructions have almost identical functionality, but are not compatible. Both contain fused multiply–add (FMA) instructions for floating-point scalar and SIMD operations, but FMA3 instructions have three operands, while FMA4 ones have four. The FMA operation has the form ''d'' = round(''a'' · ''b'' + ''c''), where the round function performs a rounding to allow the result to fit within the dest ...

Microarchitecture
In electronics, computer science and computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as μarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor. A given ISA may be implemented with different microarchitectures; implementations may vary due to different goals of a given design or due to shifts in technology. Computer architecture is the combination of microarchitecture and instruction set architecture. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the instructions, execution model, processor registers, address and data formats among other things. The microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usu ...

Zen 6
Zen 6 (''"Morpheus"'') is the name for an upcoming CPU microarchitecture from AMD, shown on their roadmap in July 2024. It is the successor to Zen 5 (''"Nirvana"'') and is believed to use TSMC's 3 nm and 2 nm processes. Desktop processors will be codenamed ''"Medusa"'' under the Ryzen 10000 name, while Epyc server processors will be codenamed ''"Venice"''. Zen 6 is expected to release in late 2026 to early 2027.

Threadripper
Threadripper, or Ryzen Threadripper, is a brand of HEDT (high-end desktop) and workstation multi-core x86-64 microprocessors designed and marketed by Advanced Micro Devices (AMD), and based on the Zen microarchitecture. It consists of central processing units (CPUs) marketed for mainstream and workstation segments, and as such comes in two line-ups, Threadripper and Threadripper PRO respectively. Background Threadripper, which is geared for high-end desktops (HEDT) and workstations, was not developed as part of a business plan or a specific roadmap. Instead, a small team inside AMD saw an opportunity to give AMD the lead in desktop CPU performance. After some progress was made in their spare time, the project was greenlit and put in an official roadmap by 2016. Characteristics Threadripper chips have higher core counts, increased power requirements, support faster memory, and more expansion opportunities. The Zen 4 core's pipelines use a high-density leading-edge 5 nm process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epyc
Epyc (stylized as 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 Inte ...

AMD-V
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 limite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
