Intel Pentium 4 2.4GHz Processor Review - Intel Pentium 4 2.4GHz - Page 4

Intel's most recent addition to the Pentium 4 line is the now famous Northwood core. This new core added more cache and reduced the size of the P4 die to allow for greater clock speeds, less heat emissions and reduction in the power needed to run the CPU. Northwood debut at 2.0A GHz, replacing the Willamette core 2.0GHz, so far Intel have remained steady in its speed production with the 2.2GHz and now our latest sample from Intel, the 2.4GHz Northwood. The NDA for this processor has just expired, follow Cameron "Sov" Johnson as he tells us all about it!

Those Pretty Pictures

 

Here we will give you a look at the different pictures of the Pentium 4 CPU and show our test platform for the review.

 

Willamette and Northwood, similar in looks but can you spot the difference

 

Below is a picture of the Northwood and Willamette core CPU's. They are labeled for you to know which is which, but can you spot the difference?

 

 

Look closely at the bottom right corner of the Northwood core picture. You will see a white dotty square image. Notice on the Willamette core it is on the other side; this is how you identify Willamette and Northwood. The Northwood core CPU at 2.0Ghz is also called the 2.0A GHz CPU, the A being the Northwood class. This is another way to tell if you have Northwood.

 

The Test Board

 

 

 

While we have a plethora of motherboards to choose from, including SiS, VIA and ALi, we choose Intel's i850 motherboard produced by EPoX; the 4T2A3. We reviewed this motherboard earlier and decided to use it for one reason alone. While DDR-266 and even DDR-333 provide scores that equal the i850 in most benchmarks, there are still some it can't outperform the RDRAM in due to its 3.2GB/s bandwidth. This bandwidth is the optimal memory config for the P4's 3.2GB/s bus.

 

Heatsink still the same

 

 

Using the Northwood core allows Intel to use the same heatsinks on the P4 2.4GHz that were used to effectively cool 1.6GHz CPU's. The heatsink area itself if massive and even at this size the cooler gets quite warm, this is due to the Intel Stock fan that revs around 2200-RPM and produces very little noise and very little air flow, but more than enough to cool the P4 beast. If you want overclocking, try something else though.

 

Overclocking

 

The Pentium 4 2.4GHz based on the Northwood core is one of the best overclocking CPU's that Intel has ever produced. Displayed below are pictures taken from our 2.4GHz Northwood running 3.0GHz using a 125MHz FSB. Due to a limited chipset overhead (i850 and RDRAM are the worst overclocking combo ever), we were unable to push past 125MHz, and even this required the RDRAM to be pushed well out of specs and needing active cooling on the modules.

 

First, Windows XP and its Info display with WCPUID

 

 

Next SiSoft Sandra 2002 CPU Benchmark

 

 

Lastly, SiSoft Sandra 2002 Multimedia Benchmark
