AVX2
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 ...

AVX-512
AVX-512 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture (ISA) proposed by Intel in July 2013, and implemented in Intel's Xeon Phi x200 (Knights Landing) and Skylake-X CPUs; this includes the Core-X series (excluding the Core i5-7640X and Core i7-7740X), as well as the new Xeon Scalable Processor Family and Xeon D-2100 Embedded Series. AVX-512 consists of multiple extensions that may be implemented independently. This policy is a departure from the historical requirement of implementing the entire instruction block. Only the core extension AVX-512F (AVX-512 Foundation) is required by all AVX-512 implementations. Besides widening most 256-bit instructions, the extensions introduce various new operations, such as new data conversions, scatter operations, and permutations. The number of AVX registers is increased from 16 to 32, and eight new "mask registers" are added, which allow for variable selection and blendi ...

Haswell (microarchitecture)
Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is a die shrink/tick of the Sandy Bridge microarchitecture). Intel officially announced CPUs based on this microarchitecture on June 4, 2013, at Computex Taipei 2013, while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum. With Haswell, which uses a 22 nm process, Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "U" suffix. Haswell CPUs are used in conjunction with the Intel 8 Series chipsets, Intel 9 Series chipsets, and Intel C220 series chipsets. At least one Haswell-based processor is still being sold as of 2022, the Pentium G3420. Design The Haswell architecture is specifically designed to optimize the power savings and performance benefits from the move to FinFET (non-planar, "3D") transistors on the improved 22 nm pr ...

Skylake (microarchitecture)
Skylake is the codename used by Intel for a processor microarchitecture that was launched in August 2015 succeeding the Broadwell microarchitecture. Skylake is a microarchitecture redesign using the same 14 nm manufacturing process technology as its predecessor, serving as a tock in Intel's tick–tock manufacturing and design model. According to Intel, the redesign brings greater CPU and GPU performance and reduced power consumption. Skylake CPUs share their microarchitecture with Kaby Lake, Coffee Lake, Cannon Lake, Whiskey Lake, and Comet Lake CPUs. Skylake is the last Intel platform on which Windows earlier than Windows 10 will be officially supported by Microsoft, although enthusiast-created modifications exist that allow Windows 8.1 and earlier to continue to receive Windows Updates on later platforms. Some of the processors based on the Skylake microarchitecture are marketed as 6th-generation Core. Intel officially declared end of life and discontinued Sk ...

Kaby Lake
Kaby Lake is Intel's codename for its seventh generation Core microprocessor family announced on August 30, 2016. Like the preceding Skylake, Kaby Lake is produced using a 14 nanometer manufacturing process technology. Breaking with Intel's previous " tick–tock" manufacturing and design model, Kaby Lake represents the optimized step of the newer process–architecture–optimization model. Kaby Lake began shipping to manufacturers and OEMs in the second quarter of 2016, and mobile chips have started shipping while Kaby Lake (desktop) chips were officially launched in January 2017. In August 2017, Intel announced Kaby Lake Refresh ( Kaby Lake R) marketed as the 8th generation mobile CPUs, breaking the long cycle where architectures matched the corresponding generations of CPUs. Skylake was anticipated to be succeeded by the 10 nanometer Cannon Lake, but it was announced in July 2015 that Cannon Lake had been delayed until the second half of 2017. In the meantime, Intel re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulldozer (microarchitecture)
The AMD Bulldozer Family 15h is a microprocessor microarchitecture for the FX and Opteron line of processors, developed by AMD for the desktop and server markets. Bulldozer is the codename for this family of microarchitectures. It was released on October 12, 2011, as the successor to the K10 microarchitecture. Bulldozer is designed from scratch, not a development of earlier processors. The core is specifically aimed at computing products with TDPs of 10 to 125 watts.

SIMD
Single instruction, multiple data (SIMD) is a type of parallel processing in Flynn's taxonomy. SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA. SIMD describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. Such machines exploit data level parallelism, but not concurrency: there are simultaneous (parallel) computations, but each unit performs the exact same instruction at any given moment (just with different data). SIMD is particularly applicable to common tasks such as adjusting the contrast in a digital image or adjusting the volume of digital audio. Most modern CPU designs include SIMD instructions to improve the performance of multimedia use. SIMD has three different subcategories in Flynn's 1972 Taxonomy, one of which is SIMT. SIMT should not be confused with software thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Lake
Rocket Lake is Intel's codename for its 11th generation Core microprocessors. Released on March 30, 2021, it is based on the new Cypress Cove microarchitecture, a variant of Sunny Cove (used by Intel's Ice Lake mobile processors) backported to Intel's 14 nm process node. Rocket Lake cores contain significantly more transistors than Skylake-derived Comet Lake cores. Rocket Lake features the same LGA 1200 socket and 400-series chipset compatibility as Comet Lake, except H410 and B460 chipsets. It is accompanied by new 500-series chipsets as well. Rocket Lake has up to eight cores, down from 10 cores for Comet Lake. It features Intel Xe graphics, and PCIe 4.0 support. Only a single M.2 drive is supported in PCIe 4.0 mode, all the rest are wired via PCIe 3.0. Intel officially launched the Rocket Lake desktop family on March 16, 2021, with sales commencing on March 30.

Streaming SIMD Extensions
In computing, Streaming SIMD Extensions (SSE) is a single instruction, multiple data (SIMD) instruction set extension to the x86 architecture, designed by Intel and introduced in 1999 in their Pentium III series of Central processing units (CPUs) shortly after the appearance of Advanced Micro Devices (AMD's) 3DNow!. SSE contains 70 new instructions (65 unique mnemonics using 70 encodings), most of which work on single precision floating-point data. SIMD instructions can greatly increase performance when exactly the same operations are to be performed on multiple data objects. Typical applications are digital signal processing and graphics processing. Intel's first IA-32 SIMD effort was the MMX instruction set. MMX had two main problems: it re-used existing x87 floating-point registers making the CPUs unable to work on both floating-point and SIMD data at the same time, and it only worked on integers. SSE floating-point instructions operate on a new independent register set, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffee Lake
Coffee Lake is Intel's codename for its eighth generation Core microprocessor family, announced on September 25, 2017. It is manufactured using Intel's second 14 nm process node refinement. Desktop Coffee Lake processors introduced i5 and i7 CPUs featuring six cores (along with hyper-threading in the case of the latter) and Core i3 CPUs with four cores and no hyperthreading. On October 8, 2018, Intel announced what it branded its ninth generation of Core processors, the Coffee Lake Refresh family. To avoid running into thermal problems at high clock speeds, Intel soldered the integrated heat spreader (IHS) to the CPU die instead of using thermal paste as on the Coffee Lake processors. The generation was defined by another increase of core counts. Coffee Lake is used with the 300-series chipset, and officially does not work with the 100- and 200-series chipset motherboards. Although desktop Coffee Lake processors use the same physical LGA 1151 socket as Skylake and Kaby Lak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
