Calxeda ECX-1000 Benchmarks vs. Intel Atom, TI OMAP4

Last week I began delivering benchmarks of the low-power yet massively scalable Calxeda EnergyCore ECX-1000 ARM Server and followed the initial tests with some ARM compiler benchmarks and other benchmarks from this 5-Watt Linux Server. In this article is what many Phoronix readers have been waiting for: comparing Calxeda's quad-core Cortex-A9 ARMv7 performance against a dual-core Texas Instruments OMAP4460 PandaBoard ES and then an Intel Atom processor.

Intel Core i5 3470

For the past month I have been testing out the Intel Core i5 3470 under Linux. Like Intel's other processors of recent years (well, ignoring the initial Sandy Bridge struggles), and just like the more expensive Ivy Bridge CPUs of this year, this mid-range quad-core processor is working very smoothly "out of the box" on modern Linux distributions.

The ARM Cortex-A9 Can Beat Out The Intel Atom

Here's some interesting test results recently uploaded to that compares the performance of ARM Cortex A8 and Cortex A9 cores running at 1.0GHz against an Intel Atom N450. All three systems running at 1.0GHz were also running Gentoo Linux. Clock-for-clock, can the latest-generation ARM Cortex-A9 take out the Intel Atom? For the most part, yes.

Intel Ivy Bridge On Linux Two-Month Redux

It has been 66 days since Intel formally introduced their Ivy Bridge processors as the 2012 successor to Sandy Bridge. My views on Intel Ivy Bridge (specifically the Core i7 3770K model) back on launch-day were very positive in terms of the Linux compatibility, CPU performance, and the HD 4000 graphics capabilities. Since then I've conducted dozens of additional tests looking at the Core i7 Ivy Bridge on Linux in different areas from comparative benchmarks to Microsoft Windows, trying to run BSD operating systems on the latest hardware, looking at the virtualization performance, compiler tuning, etc. Here is a recap of this additional Ivy Bridge testing that has happened over the past two months of near constant benchmarking.

12-Core ARM Cluster Benchmarked Against Atom, Ivy Bridge, Fusion

Last week I shared my plans to build a low-cost, 12-core, 30-watt ARMv7 cluster running Ubuntu Linux. The ARM cluster that is built around the PandaBoard ES development boards is now online and producing results... Quite surprising results actually for a low-power Cortex-A9 compute cluster. Results include performance-per-Watt comparisons to Intel Atom and Ivy Bridge processors along with AMD's Fusion APU.

Intel Core i7 3770K Ivy Bridge Linux Performance

Intel is finally announcing the first Ivy Bridge processors this morning. I have been extensively testing out the Intel Core i7 3770K, the current high-end Ivy Bridge processor, for the past few weeks under Ubuntu Linux. I have been extremely pleased with the Intel Core i7 Ivy Bridge processor under Linux with its phenomenal performance, power efficiency, and new features. This article is the first of many looking at the Linux performance of the new Intel Ivy Bridge processors.

AMD FX-8150 Bulldozer Overclocking On Ubuntu Linux

While in the weeks since the launch of the AMD FX "Bulldozer" processors we have looked at many areas of computing performance for the FX-8150 CPU, from the compiler tuning to multi-core scaling, one area that hasn't yet been covered under Linux is the AMD FX-8150 overclocking. But this article changes that.

Multi-Core Scaling Performance Of AMD's Bulldozer

There has been a lot of discussion in the past two weeks concerning AMD's new FX-Series processors and the Bulldozer architecture. In particular, with the Bulldozer architecture consisting of "modules" in which each has two x86 engines, but share much of the rest of the processing pipeline with their sibling engine; as such, the AMD FX-8150 eight-core CPU only has four modules. In this article is a look at how well the Bulldozer multi-core performance scales when toggling these different modules. The multi-core scaling performance is compared to AMD's Shanghai, Intel's Gulftown and Sandy Bridge processors.

AMD FX-8150 Bulldozer On Ubuntu Linux

Two weeks ago AMD introduced the Bulldozer FX-Series CPUs to much excitement, although many were letdown by the initial results, and it was months after showing the first Linux benchmarks of an AMD Dual-Interlagos pre-production system. In the days that followed I delivered some initial AMD FX-4100 Linux benchmarks when securing remote access to a low-end Bulldozer system running Ubuntu 11.04 (and there were also some Linux benchmarks from independent Phoronix readers), but then last week a Bulldozer kit arrived from AMD. The centerpiece of this kit is an eight-core AMD FX-8150 CPU, which is now being used to conduct a plethora of AMD Bulldozer benchmarks on Linux.

AMD FX-4100 Bulldozer

As mentioned over the weekend, a Phoronix reader that was excited about AMD's Bulldozer products had went out and immediately purchased an FX-4100 processor. This user graciously let me SSH into the system as soon as Ubuntu Linux was installed so that benchmarks from the AMD FX-4100 could be conducted. Here is a look at the AMD FX-4100 Bulldozer on Linux compared to Llano Fusion hardware and Intel Sandy Bridge processors.

First Look: AMD Trinity APU, Linux Already Runs Well

Remember those AMD Bulldozer benchmarks we showed back in March from an early engineering sample that was published to by one of AMD's partners months prior to the product launch? Well, since the consumer-grade Bulldozer chips are going to be out soon, AMD's partners are already supplying information on the AMD Trinity APUs that won't be launched until next year. The Linux performance appears quite competitive and there's also some new codenames and details to share.

Intel Core i5 2400S

Now that the Linux review of the Intel Core i3 2120 is published and there were initial benchmarks of the Core i5 2400S a few weeks back when looking at the state of Intel's "Sandy Bridge New Acceleration" architecture, the complete review of the Intel Core i5 2400S processor is here. The Core i5 2400S is meant to be an energy-efficient Sandy Bridge processor with a 65 Watt TDP compared to the i5-2400 non-S CPU that has a maximum TDP of 95 Watts like the other higher-end models, but this power reduction comes by scaling the CPU frequency back by 600MHz.

Intel Core i3 2120

Since the January launch of Intel's Sandy Bridge processors, there have been countless articles on Phoronix about Sandy Bridge under Linux. Initially detailing the troubled experience of getting the integrated graphics working but then to a point of nirvana with the open-source Intel Linux graphics driver working well and a continual stream of performance optimizations and other enhancements since that point. Sandy Bridge under Linux is now great and it is to be loved. It's also looking like Ivy Bridge on Linux will be a success, but we're still a couple months out until that hardware is released to the public. Until then, we are looking at a few more Sandy Bridge processors. In this review, for those not at XDC2011 Chicago this week, is a look at the Linux performance of the Intel Core i3 2120.

More Linux Benchmarks Of The AMD A8-3500M Fusion APU

Earlier this week we delivered launch-day Linux benchmarks of the AMD A8-3500M "Llano" Fusion APU. The results for this next-generation, quad-core Fusion chip were impressive with the graphics and compute power being several times faster than the common AMD E-350 Fusion APU. In that article we just had two other systems the A8-3500M performance was being compared to, but here are some more Linux benchmarks comparing Llano to other systems running Ubuntu 11.04.
