Pentium Processor Extreme Edition 840
Marketing at its best: The new PEE logo looks nice, but that still won't make the chip much faster than the Pentium D.
Intel's Pentium Extreme Edition 840 will support Hyper Threading and open multipliers above x14, giving users the opportunity to overclock their Extreme Edition at will. All you need is an overclocking-friendly motherboard in order to change speed settings in the BIOS. Here is where Hyper Threading may be disabled, too, which we found to be the wiser choice in many cases (see benchmarks).
We need to point out that the new Extreme Edition won't be the top performer at non-thread-level optimized applications. Here, the Pentium 4 Extreme Edition at 3.73 GHz and FSB1066 will remain Intel's fastest chip due to its higher clock and bus speeds.
2 Cores + HT = 4 Logical CPUs
Two cores with Hyper Threading enabled results in four logical processors.
