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.
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.
The Linux OpenCL support for Intel CPUs is not in as good shape as the Intel Windows OpenCL support at this time, but here are some benchmarks that explore the Intel Ivy Bridge OpenCL performance under Linux.
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.
With the upcoming availability of Ubuntu 12.04 "Precise Pangolin" being a Long-Term Support (LTS) release that will be quickly making its way into many enterprise environments, here's a look at the virtualization performance of this popular Linux distribution. In particular, being looked at is the Linux virtualization performance of KVM, Xen, and Oracle VirtualBox compared to bare metal when using Intel Sandy Bridge Extreme and AMD Bulldozer hardware.
Following the interest yesterday from the AMD A8-3870K graphics testing even though this new Llano APU has the same Radeon HD 6550D integrated graphics as the original A8-3850 APU, here's some more information and numbers from the week-old AMD A8-3870K when running the desktop AMD APU under Ubuntu Linux and attempting to overclock this week-old Llano APU.
Using the new Intel Core i7 3960X Extreme Edition Sandy Bridge processor, Scientific Linux 6.1, Debian GNU/Linux, Debian GNU/kFreeBSD, and Solaris 11 11/11 were benchmarked when having a different number of CPU cores enabled to see how well each operating system scales up to six cores plus Hyper Threading.
By now you have likely heard of the Core i7 3960X processor, which is one of the Sandy Bridge Extreme CPUs that was launched in November by Intel to much excitement and talked about quite a bit on Phoronix in the past few days. In this article is a comprehensive look at the Intel Core i7 3960X performance under 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.
For those wondering about the impact that AMD's Cool 'n' Quiet and Turbo Core technologies have under Linux for the latest-generation Bulldozer processors, here are some tests illustrating the changes in performance, power consumption, and operating temperature.
With the renewed interest in the Gallium3D LLVMpipe driver now that this software-based acceleration method is working with GNOME Shell, here are some benchmarks of this LLVM-based software driver when running some OpenGL tests on Intel Sandy Bridge and AMD Bulldozer hardware.
Now having looked at the AMD Bulldozer FX-8150 performance on Linux, as well as how it's scaling across multiple cores/modules, in this article are results when building a variety of benchmarks under the popular compilers. The tested compilers were GCC, LLVM/Clang, and AMD Open64, including different revisions of these open-source compilers.
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.
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.
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.
If you are in the market for a new notebook with an Intel Sandy Bridge processor, one of the higher-end offerings is the Core i7 2630QM, which is a quad-core processor with Hyper Threading that boasts a 2.0GHz base frequency but can ramp up to 2.9GHz thanks to Turbo Boost. In this article are some Linux benchmarks of the Intel Core i7 2630QM compared to other mobile Intel CPUs.
Remember those AMD Bulldozer benchmarks we showed back in March from an early engineering sample that was published to OpenBenchmarking.org 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.
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.
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.
Late last month there were the first Radeon HD 6550D graphics benchmarks under Linux that were published on Phoronix. There has also been a stream of A8-3850 benchmark result uploads -- among other AMD Fusion APUs -- to OpenBenchmarking.org. In this review we are providing a set of computational benchmarks from this "Llano" Fusion APU compared to a handful of other systems in our labs.
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.
This morning there will be an introduction by Advanced Micro Devices of Llano, their next-generation Fusion APU. In this article are some launch-day Linux benchmarks of this newest 32nm accelerated processing unit using Ubuntu 11.04 with the A8-3500M part. This article is in continuation of our Radeon HD 6620G Linux benchmarks that were published at midnight.
For those willing to spend $999 USD on a new processor, Intel has a new Core i7 part out that is stunningly fast. The Core i7 990X is the $999 successor to the previously reviewed Core i7 970 that ups the core frequency to 3.46GHz and provides a 3.73GHz Turbo Boost frequency. This six-core CPU with Hyper Threading works wonderful with Linux.
Up to this point when looking at the Intel Sandy Bridge performance and compatibility under Linux we have been using the Intel Core i5 2500K and Intel Core i7 2820QM. Last week though we received the Core i3 2100 (along with a Core i7 990X) from Intel and today are putting the low-end ~$125 USD Sandy Bridge processor through its paces under Linux.
Lately we have been talking a lot about Intel's latest Sandy Bridge processors under Linux due to their very competitive performance and interesting graphics abilities, but on the AMD side there has not been too much to talk about. On the low-end there is the intriguing Fusion APUs, but on the high-end they don't have an answer to Sandy Bridge until delivering their new "Bulldozer" products closer to the summer. Fortunately, we have the first Linux scoop and performance benchmarks from engineering samples of their 16-core Interlagos server chip.
By now you have likely seen the AMD Fusion E-350 APU showcased on a number of Windows web-sites, but how is this AMD Accelerated Processor working in the Linux world? At Phoronix today are the first in-depth Ubuntu Linux benchmarks being published from this promising, low-power solution designed to compete with Intel's Atom.
While we are still battling issues with the Intel Linux graphics driver in getting that running properly with Intel's new Sandy Bridge CPUs (at least Intel's Jesse Barnes is now able to reproduce the most serious problem we've been facing, but we'll save the new graphics information for another article), the CPU performance continues to be very compelling. Two weeks ago we published the Intel Core i5 2500K Linux benchmarks that showed just how well this quad-core CPU that costs a little more than $200 USD is able to truly outperform previous generations of Intel hardware. That was just with running the standard open-source benchmarks and other Linux software, which has not been optimized for Intel's latest micro-architecture. Version 4.6 of the GNU Compiler Collection (GCC) though is gearing up for release and it will bring support for the AVX extensions. In this article, we are benchmarking GCC 4.6 on a Sandy Bridge system to see what benefits there are to enabling the Core i7 AVX optimizations.
Earlier this month Intel released their first "Sandy Bridge" processors to much excitement. However, for Linux users seeking to utilize the next-generation Intel HD graphics found on these new CPUs, it meant problems. Up to this point we have largely been looking at the graphics side of Sandy Bridge, and while we have yet to publish any results there due to some isolated issues, on the CPU side its Linux experience and performance has been nothing short of incredible. Here are the first Linux benchmarks of the Intel Core i5 2500K processor.
Next week Intel is set to roll out their much-anticipated "Sandy Bridge" CPUs during the 2011 Consumer Electronics Show. With these 32nm, LGA-1155 next-generation Intel Core processors will also come the Intel P67 Chipset on a whole selection of new motherboards at launch like the ECS P67H2-A2 and ASRock P67 Pro3. How well though will Intel's newest hardware play with Linux?
Following last week's KVM vs. VirtualBox benchmarks and then looking at the multi-core scaling of KVM virtualization, we now have up some benchmarks of Amazon's EC2 (Elastic Compute Cloud) looking at the performance of this leading cloud computing service. This is just the start of some Amazon EC2 benchmarks with this article looking at the performance of their m1.large and m1.xlarge instances compared to some other hardware. There is also an OpenBenchmarking.org ID for those interested in replicating these tests.
