Ubuntu: 32-bit v. 64-bit Performance

While 64-bit support is now considered common for both Intel and AMD processors, many Linux (as well as Windows) users are uncertain whether to use a 32-bit or 64-bit operating system with there being advantages for both paths. With this being the last Phoronix article for 2006, we decided to take this opportunity to look at the common question of whether to use 32-bit or 64-bit software. In this article, we will be comparing the i386 and x86_64 performance with Ubuntu 6.10 Edgy Eft and Ubuntu 7.04 Feisty Fawn Herd 1 to see how the numbers truly stack up.

Intel Xeon 5300 Clovertown

On November 2, 2006 the embargo for Intel's Core 2 Extreme Quad QX6700 was lifted which resulted in a slurry of reviews covering this flagship desktop processor. However, this morning happens to be an important date for Supercomputing 2006 and it serves as yet another milestone for Intel Corporation. This morning Intel will be introducing the Xeon 5300 series, or perhaps better known by its codename of Clovertown. At Phoronix we have had these processors in-house for over a week now and today are able to share our thoughts on these quad-core server/workstation processors as we test them under GNU/Linux.

Intel Xeon 5150 Woodcrest

Last month Intel had announced the Woodcrest Xeon 5100 series processors for use on servers and workstations, while just days ago, Intel finally officially launched their Core 2 Duo selection. Today at Phoronix we have taken a performance look at Intel's Xeon 5150 Woodcrest processor in both single and dual configurations as well as comparing its performance against the Intel Xeon 5000 Dempsey.

Intel Core 2 Duo Family Preview

A higher level of computing performance with lower clock speeds, and lower power consumption; is that too good to be true from our blue friends at Intel? With Intel proudly brazing their Core 2 products (namely the Conroe) on this late-night adventure, we have up our technical primer on this Pentium replacement.

Intel Core Duo T2400 + Linux

Intel's Core Duo T2400 has a maximum operating frequency of 1.83GHz, 65nm process, 2MB of L2 cache, and 667MHz FSB; however, how does this dual-core component fare under Linux? We have taken a look at the Intel Core Duo T2400 in conjunction with the Lenovo ThinkPad T60, and have comparison results today against the previous Pentium M 750 1.83GHz.

Intel DDR2 FB-DIMM Performance

Intel was first to adopt DDR2 memory when they had launched their LGA-775 socket nearly two years ago with the Grantsdale and Alderwood Chipsets. Intel Corporation is first again to introduce the latest in memory technology: FB-DIMM. FB-DIMM is short for Fully Buffered Dual Inline Memory Module, and is primarily designed for mission-critical server environments that require maximum performance with minimal errors. FB-DIMMs are designed to bring the best traits from DDR2 memory while combining a new point-to-point serial memory interface. Some of the key benefits for Fully Buffered DIMMs include enhanced reliability, greater bandwidth, improved scalability, and higher capacity per memory channel. We at Phoronix have the first performance preview of the new DDR2 FB-DIMM memory modules on the Xeon Greencreek platform.

AMD Athlon 64 X2 4200+ & Sempron 3400+

After having presented our preview of the AMD Socket AM2 last week, today we finally have our first set of numbers ready to publish. Our first Linux AM2 performance report comes in way of the AMD Sempron 3400+ and AMD Athlon 64 X2 4200+.

AMD Socket AM2 Family Preview

Making headlines for months now has been countless rumors in regards to Advance Micro Device's M2/AM2 Socket. AMD's Socket AM2 is designed to bring forward several changes -- most notably, the adoption of DDR2 -- and here at Phoronix we have all the facts. With this being the morning of the long awaited pre-Computex launch, we also have up some details when it comes to AMD's finest on Linux. Continue on with our AMD AM2 Series Preview.

Intel EIST SpeedStep

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.

AMD Cool n Quiet

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.
