The announcement of another Intel processors, Pentium 4 670, is very unlikely to change anything in the current processor market. The performance of the newcomer is not very much different from the performance of Pentium 4 570. In fact, the major goal behind this processor launch is to offer an alternative to Pentium 4 570, because Intel is going to discontinue CPUs with 1M L2 cache memory in the near future. Moreover, you should also keep in mind that all currently available Pentium 4 5XX processor modifications do not support 64-bit EM64T extensions, which turns into a significant drawback today. However, in a few weeks we will see new 5X1 processor solutions, which will be just the same as regular Prescott based CPUs with added EM64T technology support. These processors are expected to start shipping on June 10.

Although the new Pentium 4 670 processors work at higher 3.8GHz core frequency, which is higher than the working frequency of the top Pentium 4 Extreme Edition CPU, we still cannot state that the newcomer appeared faster than the CPU for wealthy hardware enthusiasts. Pentium 4 Extreme Edition still wins this race due to faster bus in most applications. But at the same time, the difference between the Pentium 4 and Pentium 4 Extreme Edition processors got unacceptably small.

So, there is a pretty curious situation right now in the high-end Intel processor market: the manufacturer is offering a few processor models with about the same performance, but completely different prices. Only dual-core Pentium Extreme Edition 840 manages to stand out here, which it is faster than the top single-core solutions in a number of tasks and falls dramatically behind them in a few other applications at the same time.

All in all we get the following situation here. From the price-to-performance point of view AMD Athlon 64 processors are still the best choice for gamers. In audio and video encoding applications dual-core AMD CPUs and top Pentium 4 5XX and 6XX Intel CPUs take the lead that is why Pentium 4 5XX will look most attractive due to its lower price. In image editing tasks and during streaming video processing you will get the maximum performance if you are using only dual-core solutions from either of the manufacturers. Mathematical calculations have always been the prerogative of AMD Athlon 64. And for final rendering you might want to consider getting a dual-core AMD Athlon 64 X2. As for the regular work in popular office applications, any of the above discussed CPUs will do just fine.
