Gulftown
Gulftown or Westmere-E is the codename of an up to six-core hyperthreaded Intel processor able to run up to 12 threads in parallel. It is based on Westmere microarchitecture, the 32 nm shrink of Nehalem. Originally rumored to be called the Intel Core i9, it is sold as an Intel Core i7. The first release was the Core i7 980X in the first quarter of 2010, along with its server counterpart, the Xeon 3600 and the dual-socket Xeon 5600 (Westmere-EP) series using identical chips. Processor First figures indicate that at equivalent clock rates, depending on the software, it has up to 50% higher performance than the identically clocked quad-core Bloomfield Core i7-975. Despite having 50% more transistors, the CPU strongly benefits from the 32-nm process, drawing the same or even less power (depending on the operating system) than its Bloomfield predecessors with merely four cores. The thermal design power (TDP) of all planned models is stated to be 130 watts. Westmere-EP is the firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunnington (microprocessor)
Xeon (; ) is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for error correction code (ECC) memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture (MCA). They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Ultra Path Interconnect (UPI) bus, which replaced the o ...

Intel Core I7
Intel Core is a line of multi-core (with the exception of Core Solo and Core 2 Solo) central processing units (CPUs) for midrange, embedded, workstation, high-end and enthusiast computer markets marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets. Core was launched in January 2006 as a mobile-only series, consisting of single- and dual-core models. It was then succeeded later in July by the Core 2 series, which included both desktop and mobile processors with up to four cores, and introduced 64-bit support. Since 2008, Intel began introducing the Core i3, Core i5, Core i7 and Core i9 lineup of processors, succeeding Core 2. A new naming scheme debuted in 2023, consisting of Core 3, Core 5, and Core 7 for mainstream processors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

32 Nanometer
The "32 nm" node is the step following the "45 nm" process in CMOS (MOSFET) semiconductor device fabrication. "32-nanometre" refers to the average half-pitch (i.e., half the distance between identical features) of a memory cell at this technology level. Toshiba produced commercial 32 GiB NAND flash memory chips with the "32nm" process in 2009. Intel and AMD produced commercial microchips using the "32 nm" process in the early 2010s. IBM and the Common Platform also developed a "32 nm" high-κ metal gate process. Intel began selling its first "32 nm" processors using the Westmere architecture on 7 January 2010. Since at least 1997, "process nodes" have been named purely on a marketing basis, and have no relation to the dimensions on the integrated circuit; neither gate length, nor metal pitch, nor gate pitch on a "32nm" device is thirty-two nanometers. The "28 nm" node is an intermediate half-node die shrink based on the "32 nm" process. The "32 nm" process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AES Instruction Set
An Advanced Encryption Standard instruction set (AES instruction set) is a set of instructions that are specifically designed to perform AES encryption and decryption operations efficiently. These instructions are typically found in modern processors and can greatly accelerate AES operations compared to software implementations. An AES instruction set includes instructions for key expansion, encryption, and decryption using various key sizes (128-bit, 192-bit, and 256-bit). The instruction set is often implemented as a set of instructions that can perform a single round of AES along with a special version for the last round which has a slightly different method. When AES is implemented as an instruction set instead of as software, it can have improved security, as its side channel attack surface is reduced. x86 architecture processors AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation. AES-NI is an extension to the x8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bloomfield (microprocessor)
Bloomfield is the code name for Intel high-end desktop processors sold as Core i7-9xx and single-processor servers sold as Xeon 35xx., in almost identical configurations, replacing the earlier Yorkfield processors. The Bloomfield core is closely related to the dual-processor Gainestown, which has the same CPUID value of 0106Ax (family 6, model 26) and which uses the same socket. Bloomfield uses a different socket than the later Lynnfield and Clarksfield processors based on the same 45 nm Nehalem microarchitecture, even though some of these share the same Intel Core i7 brand. Features Bloomfield has many new features that represent significant changes from Yorkfield: * The new LGA 1366 socket is incompatible with earlier processors. * On- die memory controller: the memory is directly connected to the processor. It is called the uncore part and runs at a different clock (uncore clock) than the execution cores. ** Three channel memory: each channel can support up to ...

SSE2
SSE2 (Streaming SIMD Extensions 2) is one of the Intel SIMD (Single Instruction, Multiple Data) processor supplementary instruction sets introduced by Intel with the initial version of the Pentium 4 in 2000. SSE2 instructions allow the use of XMM (SIMD) registers on x86 instruction set architecture processors. These registers can load up to 128 bits of data and perform instructions, such as vector addition and multiplication, simultaneously. SSE2 introduced double-precision floating point instructions in addition to the single-precision floating point and integer instructions found in SSE. SSE2 extends earlier SSE instruction set by adding 144 new instructions to the previous 70 instructions. SSE2 intends to fully replace MMX, a SIMD instruction set found on IA-32 architecture processors. Competing chip-maker AMD added support for SSE2 with the introduction of their Opteron and Athlon 64 ranges of AMD64 64-bit CPUs in 2003. SSE2 was extended to create SSE3 in 2004, and e ...
