After last year's announcement that the 4.0GHz processor was "scrubbed" from the future processor launch, some were unsure as to what Intel would do to continue along Moore's Law (stating that processor computing power doubles approximately every 18 months).

Today, Intel has launched their dual core processors at 2.80, 3.0, and 3.20 GHz. These processors, while only taking one physical socket, contain two independent processor cores. Unlike Intel's Hyper-Threading technology, which can give a slight boost in performance by using idle processing time of one processor, dual core technology allows for two independent CPUs to run at the same time.

At this time, it will mean a greater punch in performance for number crunching, but the boost in performance of most general applications won't be as significant until programs are able to take advantage of multiple processor cores.

Also available in dual core format is Intel's Extreme Edition processor. This processor is running at 3.2 GHz, but unlike the standard dual core processors, Hyper-Threading technology is incorporated into each core. Instead of just having two physical processors, two additional virtual processors will be available. This Extreme Edition processor also marks Intel's first "unlocked" CPU - meaning no limitation on the "over clocking" that can be done to it out of the box.

We tested the dual core Extreme Edition processor a number of weeks ago, and were able to over clock it to 4.0GHz without any change in cooling technology. This was done on Intel's own D955XBK motherboard - another first. Intel has removed the "4%" limit on "over clocking" available on this newest board. Previous motherboards from Intel have allowed overlooking as a means of burn-in, but a hard limit of 4% was coded in. The Intel motherboard using the 945 chipset will still contain the 4% cap.

Users must be aware that over clocking will void the warranty if anything were to happen as it can be detected. In regards to the motherboard, over clocking beyond 4GHz may overheat and/or burn out critical components if not properly cooled. The voltage regulators and FETs will need to be cooled with a custom solution in order to keep them under critical levels as they offer no built-in protection. Although the Intel processors have technology enabling them to shutdown or throttle back if they are approaching dangerous operating conditions, components on the motherboard do not offer that level of protection. The motherboard may begin to delaminate and components may burn out, damaging nearby items such as the CPU.

Each Pentium D processor (no longer Pentium 4) will be capable of 64-bit extensions, Enhanced Intel Speed Step Technology, and Execute-Bit Disable. They will also feature 1MB L2 cache per core, an 800MHz front side bus speed, and be in the LGA775 (Socket T) format. Only the Extreme Edition processor will feature Hyper-Threading technology.

The following processors are being launched today:
Pentium D 820 - Item BX80551PG2800FN, 2.80E GHz processor.
Pentium D 830 - Item BX80551PG3000FN, 3.00E GHz processor.
Pentium D 840 - Item BX80551PG3200FN, 3.20E GHz processor.

The Intel Pentium Processor Extreme Edition 840 has been available for a while, but will hit general availability shortly. The Item code is BX80551PGH3200F, and it features Hyper-Threading technology, giving newer operating systems the appearance of working with 4 CPUs (2 physical, 2 virtual).
