When was dual core processor invented

Enhanced Speedstep Technology Introduced with the Pentium M and enables the processor to alter its clock frequency based on the computation needs at the time. In addition, the Pentium M architecture includes separate power lines to different execution units allowing the autonomous disabling of idle execution units and data paths during the processing of an instruction. Advanced Thermal Manager Supports new digital temperature sensors and thermal monitors on each execution core to enhance thermal monitoring accuracy.

This allows for more power efficiency savings over the Pentium M by the independent scaling of power between the two cores. Dynamic Power Coordination This feature cuts down the chipset's power consumption while the processor is running at reduced clock speeds by switching processor states between the Halt, Stop Clock, and Deep Sleep dynamically, and in the 2-core mode — synchronously to the Deeper and Enhanced Deeper Sleep modes.

This distributed logic coordinates operation of the Enhanced Intel SpeedStep mode as well as switching between the C-states, which results in low supply voltage operation for Core Duo chips and minimum heat dissipation in the active state. Intel released their desktop equivalent Pentium Dual Core branded processors on June 3, with the Pentium E and E, and subsequently the E in September Wolfdale is basically a dual-core desktop Penryn core with a 6MB L2 cache shared between the two cores using 45nm process technology, which provides for a smaller core over previous processors in the Core 2 Duo series.

Just like all Pentium Dual Cores, only part of its L2 cache is enabled, but nonetheless, its 2MB L2 cache is larger than the other processors currently in the series. The energy consumption of the processors is shown in the letter in front of the model code:. A detailed list of all current models is here: Mobile Processor Overview. A list of all mobile processors according to performance is here: Benchmark list of mobile processors.

Intel Core iH. Deschutes arrived as a shrink to nm and clock speeds up to nm in , and was also offered as Pentium II Overdrive as an upgrade option for the Pentium Pro.

In the same year, Intel also offered the Deschutes core as a Pentium II Xeon with larger cache and dual-processor support. Intel's low-end consumer processor Celeron was launched in as a variant of the Pentium II processor. While Celerons are based on the company's current processor technology, they usually come with substantial downgrades, such as less cache memory, which positions them as processors that are just "good enough" for the most basic PC applications and allows Intel to compete at the very bottom of the PC market.

The first Celeron series was based on the nm Covington core for desktops and the nm Mendocino core 19 million transistors, including L2 on-die cache for notebooks. The processors were available from to MHz on the desktop and up to MHz on the mobile side, and were updated well into the days of the succeeding Pentium III.

Today's Celerons are based on Sandy Bridge architecture. The chip was initially released with the nm Katmai core and was quickly scaled down to nm with Coppermine, Coppermine T and to nm with the Tualatin core. The transistor count jumped from 9. Intel was criticized to have rushed out the first gigahertz versions to compete with AMD's Athlon, which forced the company to recall its gigahertz processors and re-release them at a later time.

Also noteworthy on the consumer side was the announcement of the Mobile Pentium III in , which introduced SpeedStep and a scaling ability of clock speed of the processor, depending on its operation mode. The chip was released with the Tanner core in The feature caused several privacy complaints, and Intel eventually removed the feature and did not carry it over to future CPUs. The Pentium 4 arguably took Intel on a path that led to the most dramatic transformation of Intel in the company's history.

Launched in with the nm Willamette core 42 million transistors , the chip's Netburst architecture was designed to scale with clock speed, and Intel envisioned that the foundation would allow the company to hit frequencies of more than 20 GHz by Netburst, however, was more limited than initially thought, and by , Intel knew that the current leakage and power consumption was increasing with higher clock speeds too fast.

Netburst launched with 1. Intel also launched the first Extreme Edition processors with the Gallatin core in Over time, the Pentium 4 series became increasingly confusing, with Mobile Pentium 4-M processors, Pentium 4E HT hyperthreading processors with support for a virtual second core, and Pentium 4F processors with the 65 nm Cedar Mill core Pentium 4 series in Intel planned to replace the Pentium 4 family with the Tejas processor, but canceled the project when it was clear that Netburst would not be able to reach clock speeds beyond 3.

Core, the following architecture, was a dramatic turnaround to much more efficient CPUs with a strict power ceiling that put Intel's gigahertz machine in reverse. The first Xeon that did not bring the Pentium brand along was based on Pentium 4's Netburst architecture and debuted with the nm Foster core.

It was available with 1. Similar to its desktop processors, the Netburst processors suffered from excessive power consumption, which forced Intel to revise its processor architecture and strategy. Today's Xeons are still based on the technology foundation that is also used for desktop and mobile processors, but Intel keeps them in a tight power envelope.

The dual-core Woodcrest chip, a variant of the desktop Conroe chip, was the first representative of this new idea. The CPUs have up to 10 cores and clock speeds up to 3. The Itanium has been Intel's most misunderstood processor that actually survived over a long period of time. While it follows the idea of the i and iAPX , it has found some powerful supporters and not been cut yet. The processor was launched as Intel's first bit processor and was believed to be Intel's general idea for a bit platform.

However, the Itanium suffered in the bit department and was heavily criticized for its lack of performance in this segment. Itanium was launched with the nm Merced core in as a mainframe processor with MHz and MHz clock speed and million transistors — more than six times the count of a desktop Pentium at the time. The Itanium 2 followed in nm McKinley core, as well as nm Madison, Deerfield, Hondo, Fanwood and Madison cores and wasn't updated until when Intel launched the Itanium with the 90 nm Montecito and Montvale cores, as well as the 65 nm Tukwila core with a massive 24 MB on-die cache, as well as more than 2 billion transistors.

Despite persistent rumors that Intel will kill the Itanium at any time, there is a solid service ecosystem surrounding the processor.

Hyperthreading works by duplicating certain sections of the processor, allowing the operating system to address a single physical processor with two logical processors per core. The operating system is then able to execute two threads simultaneously by allowing one thread to run while the other is stalled, usually due to a data dependency.

At the time, Intel claimed a performance improvement of up to 30 percent over a non-hyperthreaded Pentium 4. In our previous tests, we've shown that a hyperthreaded 3 GHz chip can surpass the speed of a non-hyperthreaded 3. The Pentium M series, launched with the nm Banias core in , was targeted at mobile computers but carried the philosophy of an Intel that did not focus its processors on clock speed anymore, but on power efficiency.

The processor was developed by Intel's design team in Israel, which was led by Mooly Eden and David Perlmutter, who both hold key executive roles at Intel today. Banias dropped its clock speed to MHz to 1. However, the processor was rated at just The 90 nm shrink was called Dothan and dropped its thermal design power to 21 watts.

Dothan had million transistors and clock speeds of up to 2. The direct successor of Dothan was Yonah, which was released in as Core Duo and Core Solo, but was not related to the Intel Core micro-architecture.

The Banias core and its impact on Intel is seen on the same level as the , and as the most significant milestones in the company's product history. The Pentium D was Intel's first dual-core processor. Still based on Netburst, the first version had the 90 nm Smithfield core two Northwood cores and was released as the Pentium D series. It was succeeded by the 65 nm Presler with two Cedar Mill cores dual-core. Intel also released Extreme Editions of both processors and capped the maximum clock speed at 3.

Smithfield had million transistors, Prescott million. Intel's Terascale Computing Research Program TSCR started sometime around as a means to address the various challenges faced in scaling chips beyond four cores and to experiment with improving communication within the processors themselves.

The K5 was the first processor developed completely in-house by AMD. It also featured an on-die L2 cache. AMD introduced the Athlon processor series on June 23, The Athlon would be produced for the next six years in speeds ranging from MHz up to 2.

The Duron was built on the same K7 architecture as the Athlon processor. Intel announced on August 28th that it would recall its 1. Users with these processors should contact their vendors for additional information about the recall. On January 3, , Intel released the 1. AMD announced a new branding scheme on October 9, Each higher model number represented a higher clock speed. Intel released the Celeron 1.
