However, no 64-bit Windows drivers are available for Intel Atom Cedarview processors, released Q3 2011. [24] However, Intel's Bay Trail-M processors, built on the Silvermont microarchitecture and released in the second half of 2013, regain 64-bit support, although driver support for Linux and Windows 7 is limited at launch.

Intel 5-level paging, referred to simply as 5-level paging in Intel documents, is a processor extension for the x86-64 line of processors. [ 1 ] : 11 It extends the size of virtual addresses from 48 bits to 57 bits by adding an additional level to x86-64's multilevel page tables , increasing the addressable virtual memory from 256 TB to 128 PB .
The five-volume set of the x86-64 Architecture Programmer's Manual, as published and distributed by AMD in 2002. x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [ note 1] is a 64-bit version of the x86 instruction set, first announced in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new ...
Physical Address Extension. In computing, Physical Address Extension ( PAE ), sometimes referred to as Page Address Extension, [ 1] is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. [ 2] It defines a page table hierarchy of three levels ...
In 2003, 64-bit CPUs were introduced to the mainstream PC market in the form of x86-64 processors and the PowerPC G5 . A 64-bit register can hold any of 2 64 (over 18 quintillion or 1.8×10 19) different values. The range of integer values that can be stored in 64 bits depends on the integer representation used.
Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013. [ 1] Instructions for SHA-512 will be introduced in Arrow Lake and Lunar Lake in 2024. The original SSE -based extensions added four instructions supporting SHA ...
x86 virtualization. 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.
Both firms talk with one another's competitors from time to time, most notably with Microsoft's close relationship with AMD and the development of Windows XP Professional x64 Edition utilizing AMD-designed 64-bit extensions to the x86 architecture, and Intel's decision to sell its processors to Apple Inc.
