Benchmarks: Intel's 64-bit Pentium 4 660
Published: 03 Mar 2005
Improved power management
The new 6xx-series Pentium 4 processors benefit from improved power management in the shape of Enhanced Intel Speedstep Technology (EIST). The addition of this feature, along with improvements in the fabrication process, results in lower power consumption.
EIST provides similar functionality to AMD's Cool 'n Quiet technology in its Athlon 64 processors. If the system is in Idle mode, the voltage and clock frequency are reduced. As the CPU load increases, the voltage and clock frequency are gradually stepped up. The power consumption figures below demonstrate the effect of this technology. The Pentium 4 560 system without EIST (Intel D925XCV motherboard, 2 x 512MB Micron DDR2 RAM, MSI GeForce 6600GT, Maxtor Maxline III 250GB) uses 153 Watts in Idle mode, and this is reduced by 40 Watts when the EIST-equipped Pentium 4 660 is used instead. That's all the more impressive when you consider that Intel's new chip contains more transistors thanks to its 2MB of Level 2 cache. Compared to AMD's Athlon 64 4000+ (Asus A8N-SLI Deluxe), the Pentium 4 600 has closed the power consumption gap significantly, and is now only ten per cent behind.

* Maximum power consumption is measured using the CPU Stability Test 6.0 utility. If there is additional load on the graphics card, the system's maximum power consumption will be higher still. Note: the power consumption figures refer to complete systems with otherwise identical specifications.
