techreport.com: Intel's Nehalem-based Xeons are finally here, and they've left us gasping for air. This may well be the largest performance jump from one CPU generation to the next that we've ever seen. Idle power draw is way, way down, as well. The downside? We're still looking for one.

Intel Xeon 5150 vs. E5320

techwarelabs.com: Intel and AMD have each had their own CPU's targeted towards the server market for a long time now. With the relatively recent arrival of multiple core CPU's to the mainstream market one is left wondering what the difference between the current mainstream Intel Core 2 Duo (code named Conroe) processor and a Xeon really is.

Intel Xeon X3210 2.13GHz

techgage.com: One of the most popular CPUs on the market right now is the Q6600, thanks to the fact that it offers four cores at 2.4GHz. But what about the Xeon's? Their prices are also more affordable now, with their X3210 2.13GHz retailing for $260. Read on as we pit this Quad-Core against the rest of our fleet.

Intel Xeon X5570 and E5520

legitreviews.com: Our quick look at the Intel Xeon 5500 series was a very impressive one. The Intel Xeon X5570 that we looked at today operates at 2.93GHz during normal operation, but when Turbo Boost Technology is enabled the operating frequencies increased up to 3.33GHz.

Intel Xeon X3320 45nm Quad

madshrimps.be: The Xeon X3320 is the server version of the desktop Q9300 Quad Core processor, the new 45nm process makes this a cool running CPU. In this quick overclocking test we see if the X3320 which comes with stock 2.5Ghz clocks is any good at overclocking.

Intel P4 820 D vs. 670

lostcircuits.com: Awhile ago, Intel released two processors, geared towards the high-end and the low-end of the market, respectively, namely the dual core P4 820D and the high frequency P4 670. Whereas it is possible to migrate from any other 600 or 500 series P4 on a 925 / 915 chipset based mother board to the 670, the 820D, as well as any of the other new dual core CPUs will require a new mainboard sporting either the 955X or else the lower end 945 chipset and, therefore, the "upgrade" will put a larger dent into the wallet than what the isolated CPU price would suggest.

Intel Pentium 4 560

viperlair.com: To sum it up, the P4 560, and the compatible chipsets can be viewed as a first step for Intel. Although it was generally the fastest chip in our application benchmarks, it wasn't what I would call revolutionary. The platform as a whole still needs to go through some growing pains, and I think it will take some time before the other complimentary technologies catch up a bit to make the LGA775 platform standout.
