Quad-core Intel Kentsfield processors

Quad-core Intel Kentsfield processors
Author: Aleksandr Mitrofanov
Date: 02.11.2006

We used the following components:


Processor CPU Intel Core 2 Extreme QX6700 Socket LGA775 2.66 GHz (Kentsfield core, stepping B3)
CPU Intel Core 2 Duo E6700 Socket LGA775 2.66 GHz (Conroe core, stepping B1)
CPU AMD Athlon64 3500+ Socket939 2.2 GHz (NewCastle core, stepping CG)
CPU AMD Athlon X2 4800+ Socket939 2.4 GHz (Toledo core, stepping E6)
CPU Intel Pentium4 660 Socket LGA775 3.6 GHz (Prescott-2M core, stepping N0)
CPU Intel Pentium D 820 Socket LGA775 2.8 GHz (Smithfield core, stepping A0)
CPU Intel Pentium EE 955 Socket LGA775 3.46 GHz (Presler core)
Motherboard Asus A8N-SLI Deluxe (nForce4 SLI)
Asus P5WD2 Premium (Intel 955X)
ASUS P5W-DH Deluxe (Intel 975X)
Cooler Gigabyte G-Power
Video Card ASUS EN6600 GT (GeForce 6600GT ; PCI Express x16)
Driver version: 81.89
Sound card -
HDD IBM DTLA 307030 30 GB
Memory 2x256 MB PC3200 400512ELDCPER2-K Platinum rev2.0 by OCZ
2x512 MB Corsair DDR2 TWIN2X1024-8000UL1
Housing Inwin506 with the PSU PowerMan 300 Â/PowerMan 550 W
OS Windows XP SP1

We used a customary set of application benchmarks. Let's first take a look at the results of synthetic benchmarks.


These are exclusively synthetic benchmarks which demonstrate the theoretical performance.

Now on to the gaming benchmarks.












Kb/s, the more - the better










We included the results of overclocked processors into the list in order to estimate the scaling of performance as the clock speed goes up. Besides, our readers should be well aware of what they are after when buying a certain processor.

Final Words

The conclusions are very simple. First, 4-core Kentsfield processors are aimed solely at professionals who use optimized software. In any case, regular users of such software can purchase this processor, unless they are scared away by the price (about 1000$). Foe this money, the user gets a system which is almost 1.5 times faster than that based on the CPU Conroe, and 3-4 times faster than single-core processors.

For all the other users, Kentsfield is not yet a necessity. Even on occasional use of optimized software, dual-core Conroe fully meets all the needs and requirements.

As regards the overclocking, at that the technology limit of Kentsfield is absolutely the same as in Conroe. But the heat emission of the new processor is much higher and reaches 130 W. In fact, due to Prescott this value is not scaring for users, and retail shops offer respective cooling systems and power supply units.

P.S. Join the conference with all your questions, remarks and suggestions.
