Last week we published an in-depth article looking at the NVIDIA ION Linux Performance using a nettop device that contained this chipset with GeForce 9400M graphics rather than the usual Intel 945 graphics. From video playback to 2D to 3D, the graphics performance with the NVIDIA ION was wonderful. For that testing, the nettop we were using came courtesy of ZaReason and it was their new Ion Breeze 3770. In this review we are taking a closer look at the ZaReason Ion Breeze 3770 hardware.

To those running ATI Radeon graphics cards on Linux, this week has been very important with several key announcements having been made. The TTM memory manager is getting ready for inclusion into the Linux kernel, which finally will allow the open-source ATI driver (and soon the Nouveau driver too for NVIDIA hardware) to have kernel-based GPU memory management. With the memory management work set in the ATI driver via a mix of TTM and GEM, the ATI kernel mode-setting is also getting ready to be released as a staging driver within the Linux 2.6.31 kernel. The announcements this week have not been only about the GPU and Linux kernel, but the Radeon driver rewrite has also been merged to master. As we discussed in yesterday's news post, this Radeon Mesa re-write brings several key improvements immediately and there are still more features to come.

Fedora 11 was released earlier this week so we have set out to see how its desktop performance compares to that of Ubuntu 9.04, which was released back in April. Using the Phoronix Test Suite we compared these two leading Linux distributions in tasks like code compilation, Apache web server performance, audio/video encoding, multi-processing, ray-tracing, computational biology, various disk tasks, graphics manipulation, encryption, chess AI, image conversion, database, and other tests.

Earlier this year NVIDIA introduced the ION, which is their new system platform that pairs a GeForce 9400M GPU with an Intel Atom processor to make it an appealing platform for those desiring a netbook or nettop computer but are interested in a higher level of graphics performance than what is currently possible with Intel's integrated graphics. Products using the NVIDIA ION have been slow to emerge, but in recent weeks, we have begun seeing more devices around, including those from smaller manufacturers. One company that is now selling an ION-powered nettop is ZaReason, which is a Linux-focused hardware company. In this article we have a whole arsenal of Linux-based tests showing off the NVIDIA graphics performance with the Intel Atom processor under Linux.

Kernel mode-setting for Intel graphics hardware can already be found in the mainline Linux kernel and will be included by default in the release of Ubuntu 9.10 later this year. While Intel's kernel mode-setting support has been maturing in a steadfast manner, this support has not been moving along quite as fast for ATI and NVIDIA hardware. It is possible we will see ATI/AMD kernel mode-setting along with the necessary memory management support enter the Linux 2.6.31 kernel and potentially see this feature appear in Ubuntu 9.10 as an end-user option, but currently this support is still deemed under development. For those with ATI Radeon hardware looking to test out kernel mode-setting, there is now a Launchpad PPA and a LiveCD available for testing out these mode-setting capabilities atop Ubuntu.

As we reported last week, the release of OpenSolaris 2009.06 would come on Monday, and sure enough, it has been released by Sun Microsystems. The OpenSolaris 2009.06 release presents network virtualization support with Crossbow, SPARC support, Intel Xeon 5500 series hardware support, MySQL and PHP DTrace probes, improved usability with its package management system, and much more.

One month ago we provided benchmarks of the Btrfs file-system and found that while it contained many features to make it a next-generation Linux file-system, its disk performance was rather displeasing. We had found the EXT4 file-system ran faster in a number of the tests and even EXT3 and XFS had their own advantages. Besides offering features like snapshots and online defragmentation, Btrfs has a mode that is optimized for solid-state drives. Will the Btrfs SSD mode cause this new Oracle-sponsored file-system to be the best for non-rotating media? We have benchmarks in this article, but the results may not be what one would expect.

With the Linux 2.6.30 kernel being prepped for release in early June, we have set out to provide a few benchmarks of this latest Linux kernel to see how it compares to its two earlier predecessors. While this new kernel may offer support for new file-systems (NILFS2, in particular), support for LZMA/BZIP2 kernel image compression, a new CPU architecture (Microblaze) and many other changes, are there any major performance regressions or improvements like we have spotted with our previous Linux kernel benchmarks?

X.Org 7.5 with the X Server 1.7 update has been delayed, again. X.Org 7.5 was originally scheduled for release in early April but that ended up being an April Fool's Day joke. In late April the X.Org 7.5 / X Server 1.7 release schedule was then revised for a July release. The feature freeze for X Server 1.7 was supposed to occur last week, but Daniel Stone has announced this morning that X.Org 7.5 will be set back by another month.

Earlier this year AMD launched the Phenom II series to succeed the original quad-core Phenom processors, with these newer desktop CPUs being built upon a 45nm process, tripling the amount of Level 3 cache to 6MB, and offering support for both DDR2 and DDR3 system memory. Prior to the launch of the Phenom II we had tested the AMD Shanghai Opterons on Linux and benchmarked these CPUs on OpenSolaris too, which were the server/workstation version of this new AMD 45nm core. With the Phenom II series there is the X3 and X4 line-up for triple-core and quad-core processors, respectively. In this article we are looking at how well the AMD Phenom II X3 710 performs under Ubuntu Linux.

Besides offering an impressive selection of USB flash drives and DDR2/DDR3 memory products, OCZ Technology has been quick to expand their selection of solid state drives. OCZ manufacturers SSD products in their value, mainstream, performance, and enterprise series with some of these series containing multiple product families. Earlier this year we provided Linux SSD benchmarks using an OCZ Core Series V2 SSD, but introduced just recently has been the OCZ Vertex SSD series, which we happen to be reviewing today. The OCZ Vertex SSDs go up to 256GB in size and offers 64MB of onboard cache, RAID support, and is rated for 1.5 million hours MTBF.

While the Unigine game engine may not be as widely known or used as the Unreal or id Tech engines, its capabilities and features have been increasing at an incredible rate. Last year there were two tech demos released by Unigine Corp to demonstrate the capabilities of their proprietary engine -- both of which were very impressive -- but since then their software stack has picked up a slew of new features like improved physics and multiplayer support. This year they are slated to release a new in-house game / tech demo that will be even more impressive and will go head-to-head with the latest high-end commercial game engines. Through all of their game engine development work, they continue to support Linux gaming, so we recently carried out an interview with them to learn more about their current and future work.

Last year the Wayland Display Server project was started by Kristian Høgsberg, a Red Hat developer and a name known well within the X.Org community for his work on AIGLX, Direct Rendering Infrastructure 2, and various other projects. We were first to talk about the Wayland Display Server in detail, which aims to provide a mini display server that is designed around the latest X/kernel technologies like the Graphics Execution Manager and kernel mode-setting. Wayland also integrates its own compositing manager and is designed to produce a perfect frame (a.k.a. no tearing) each and every time. There has not been much to report on this project recently, but we now have a status update courtesy of Kristian.

We first got excited for Moblin 2.0 back in January when seeing how fast this Linux distribution had booted on Atom-powered netbooks. This Fedora-derived distribution booted even faster with a newer development release that came out this past March. While Moblin 2.0 final is not yet released, there is now more to get excited over than just amazing boot times. Moblin 2.0 will introduce a Clutter-based user interface and from our initial encounters with this release, it is very impressive! In this article we have more information on this new UI along with screenshots and videos.

Last week we published Ubuntu 9.04 vs. Mac OS X 10.5.6 benchmarks where we compared the performance of these two popular operating systems on a Mac Mini. With the OS X kernel currently being 32-bit but with support for 64-bit applications, we had used the 32-bit version of Ubuntu 9.04. In a majority of the Leopard operating system from Apple outperformed Canonical's Jaunty Jackalope, but today we are adding in the results from an Ubuntu 64-bit installation. As you can see from the results, the x86_64 version of Ubuntu Linux is more competitive against Mac OS X 10.5.6.

The first alpha release for Ubuntu 9.10 was made available yesterday and while it does net yet integrate Plymouth or any other new features, it has picked up a few new packages. Most prominently, Ubuntu 9.10 Alpha 1 features the Linux 2.6.30 kernel and GCC 4.4. There are also other updated packages from Debian like GNOME 2.27, but most notable are the kernel and compiler updates. We have tested out Ubuntu 9.10 Alpha 1 and compared its performance to Ubuntu 9.04. While this is very early within the Ubuntu 9.10 development cycle, the results already may come as a surprise.

Support for the Creative X-Fi sound cards on Linux has been a mess to say the least. These high-end audio processors were released by Creative Labs about four years ago and there still isn't pleasant support for the X-Fi series on Linux. Months after the sound cards launched there was word from Creative Labs that they would provide a Linux driver complete with support for ALSA and OpenAL with EAX.

For as long as I can recall, ATI/AMD video cards have typically had decent support in Linux. It's not hard to pick out points in time where drivers were slow to come (R300 sticks out in my mind), but that was not due to the lack of effort by the open-source community as it was the difficulty reverse engineering a chip with no documentation. Intel seems to be the one getting most of the press these days regarding their open-source graphics support, but AMD is putting forth its own notable effort as well. They have multiple full time employees working on open-source support and have released specifications and programming documentation for their entire range of chips. The past few months have seen a flurry of activity in graphics related development, and a fair amount of this is centered around AMD hardware.

Last year we provided benchmarks looking at Ubuntu versus Mac OS X when it came to using the latest releases for both software platforms at the time. Both operating systems had performed competitively -- in some tests, the Apple OS wound up on top while in other areas Canonical had the advantage. Since that article back in November, Apple has released a minor update to Leopard (v10.5.6) and Canonical last month released Ubuntu 9.04. We have already looked at the performance of Ubuntu's Jaunty Jackalope, and even found it to perform with old hardware, but how does it now compete with Mac OS X? We have more benchmarks this morning to continue this performance investigation.

AMD ended out last year by releasing basic R600/700 3D code that allowed the rendering of open-source triangles, but not much in the way of usable OpenGL acceleration for end-users. Just last month AMD had then pushed out new R600/700 code that plugged into the Mesa stack and is being used as the groundwork for the providing open-source OpenGL acceleration on the Linux desktop with newer ATI graphics processors. In between December and April, AMD had also released extensive documentation covering the 3D engines on the R600 and R700 graphics processors along with the R700 instruction set architecture. While the open-source 3D support is still emerging for the Radeon HD 2000, 3000, and 4000 series, AMD has released some more documentation. This time around they have a programming guide for those developers interested in understanding the latest ATI GPUs.
