February 16, 2006 -- Intel's SpeedStep Technology has origins tracing back to the days of the Mobile Pentium 3 and Pentium 2 processors with Geyserville Technology. However, at that time, the 1GHz Pentium 3 model was the fastest and required 1.7V for operation, and its maximum power consumption was 34W! Since that time, many of the processor technologies have been phased out and have brought new features in the Pentium 4, Celeron M, Pentium M, and most recently the Core Duo series. However, over six years later SpeedStep Technology remains in their mobile platform as well as some Pentium 4 and Pentium D processors. At hand today are the results from our most recent (EIST) Enhanced Intel SpeedStep Technology investigation.
February 07, 2006 -- Introduced way back with the launch of Advanced Micro Devices Athlon 64 processors was Cool 'n' Quiet Technology, as the successor to PowerNow! Today at Phoronix we are looking at the performance of AMD's Cool 'n' Quiet under Linux when it comes to the CPU temperature, power consumption, and overall desktop performance and usage.
December 19, 2005 -- In our previous piece yesterday, we had covered the performance benefits of using a 16MB cache on 2.5-inch mobile devices compared to the traditional 8MB capacity and overall we were pleasantly surprised by our penguin findings. Today we are going to be looking again at mobile memory performance under Linux but rather than the form of permanent storage, we are examining various memory configurations and its effect on the Pentium M performance. In this article we will be testing the system in 512MB, 1GB, and 2GB DDR2 PC2-4200 configurations.
September 18, 2005 -- DFI's 855GME-MGF motherboard has been receiving a fair amount of attention in recent months due to its Socket 479 Pentium M support. When an Intel Pentium M is utilized in conjunction with one of these Socket 479 desktop motherboards, the high performance level can be quite shocking. Although we're running the Pentium M 750 notebook at stock speeds in this article, we've posted some results to demonstrate Intel's mobile capabilities under Linux. Hitting the bench today is an IBM/Lenovo ThinkPad R52 with 1.86GHz Pentium M processor, i915 Express Chipset, 512MB DDR2, and an ATI X300 utilizing GCC 4.0 and the Linux 2.6.12 kernel.
July 05, 2005 -- As most of you are aware, AMD's Athlon 64 flagship single core is currently the San Diego, in fact the Athlon 64 FX-57 is based upon the San Diego. The key difference between the San Diego and its Venice counterpart is the amount of L2 Cache. But just how well do these two cores compare clock-for-clock? In this review will be running two of these CPUs at 2.0, 2.2, and 2.6GHz to see the performance difference between the two AMD cores.
November 13, 2004 -- Deleron, CellyD, Celery D, or whatever you would like to call the new Intel Celeron D processors, they undoubtedly have some enthusiasts talking over its Prescott core. In this article today, we got our hands on the new Intel Celeron D 320 that runs at 2.4GHz and utilizes the Prescott core with 90 nm process.
