Pentium 4 moves house - New Socket and Platform surfaces from Intel - LGA775 vs. mPGA478 - Comparing the Processors

Last weekend Intel introduced a brand new range of products to the world for its Pentium 4 platform. With it comes a bunch of changes including the new LGA775 socket, DDR-II memory and PCI Express support along with two new chipsets and two new processors. We've got the lot covered in this article which investigates the changes from Socket 478 and what type of performance can we expect from the new designs right now.

LGA775 vs. mPGA478


Now we get down to the processors.



The new CPU naming scheme that has been floating around the web has now taken affect on the Prescott series of LGA775 processors. The test sample that Intel has sent us is the Pentium 4 560 which has a core speed of 3.6GHz using an 18x multiplier and 200MHz FSB.


In terms of technology updates, there aren't any, apart from the move from the mPGA478 socket. The internal architecture is the same as the mPGA478 Prescott. Though, this is the latest stepping CPU from Intel, designed to generate less heat than the original design. Intel is set to use the LGA775 platform to push the processor well beyond the speedy 4GHz barrier.


LGA775 isn't just limited to the Prescott CPU. Intel also sent the latest Intel Pentium 4 3.4GHz Extreme Edition CPU for testing. That's right; EE comes to the new socket as well. For the value segment, Intel Celeron D series will soon make its debut on the LGA775 series socket with a 533FSB, leaving the Socket 478 to slowly fade into the background, just like Socket 423 did.
