Phoronix is taking the latest Ubuntu release and testing the performance on AMD's FX 8150 against Intel's Core-i7 3960X to see their relative performance in a virtual environment.   Both machines had issues, Xen had critical issues which prevented it from running on the Bulldozer and ASUS motherboard system, while the Sandy Bridge chip had issues with Virtualbox.  The testing was not so much a comparison of the performance difference between the two chips as it is a test of efficiency of these processors running tasks when virtualized.  As both chips averaged 90%+ of base performance when virtualized you can see that both architectures have come a long way in this particular usage.

Also, keep your eyes out for a CPU review from Josh which should be arriving soon.

"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."

See what happens when you harness three GPUs to a Bulldozer and try to get them to pull it along

In a good mood?  If so, do not read this [H]ard|OCP article on Bulldozer's gaming performance when coupled with two and three GTX580s.  By using an SLI setup you can see just how powerful a CPU is as it tries to keep up with the GPUs and as you might expect the Bulldozer is not up to the task.  In most tests [H] saw a 70% performance difference between the FX 8150 and the Core-i5 2500K, with both processors clocked at 4.8GHz.  In a very few tests the results were a little closer but this is bad news for AMD, especially when you consider it is the more expensive of the two chips.

"We are taking the new AMD FX-8150 and giving it the power of Dual and Triple-SLI GeForce GTX 580 video cards. We are going to take the new CPU up to large NV Surround resolutions and see how performance stacks up when it comes to high-end gaming scenarios."

Bulldozer, get out of the way! This review is supposed to be about the ASUS Crosshair V Formula

As sometimes happens when one sets out to write a review, at some point it turns out you aren't reviewing what you had originally intended to.  Such happened at Legit Reviews when they tested the ASUS Crosshair V Formula AM3+ board with an FX-8150 as well as an X6 1100T.  The motherboard is very interesting; just hard to make out through the wreckage of a big yellow machine lying in front of it.  If you can manage to make out the motherboard through the Phenom-enal holes punched in the 'dozer you can see three PCIe 2.0 x16 (dual x16 or x16, x8, x8), a PCIe 2.0 x16 in x4, a PCIe 2.0 x1 slot and even a legacy PCI slot.  There are also four USB 3.0 ports and an equal number of USB 2.0 ports (one can be made into an ROG port)  and a slew of others including a clear CMOS button for your cat or child to play with.

"This particular article, we went a little bit of a different route. We compared the ASUS Crosshair V Formula with the latest AMD FX-8150 'Bulldozer' processor, to itself with an AMD Phenom II X6 1100T. We wanted to see if there was much of a difference in performance between the two core architectures on the AMD 990FX chipset. The article inadvertently felt more like a shoot out between the two processors, when the focus was meant to be on the ASUS Crosshair V Formula. The performance between the two systems was entirely too similar for my tastes. The AMD FX-8150 didn't run the circles around the Phenom II X6 1100T that I had hoped it would..."

Bulldozing through Linux benchmarks

With the lacklustre performance we saw from AMD's new Bulldozer CPUs on Windows except in seriously multi-threaded applications; it is with a hopeful heart that Phoronix tests the performance of the FX-8150 under Ubuntu 11.04.  There are a lot of benchmarks to go through, from general performance to specific AMD-centric tests to those focusing specifically on multi-threaded performance and even a look at the bundled watercooler.  Read through the benchmarks they've run themselves as well as user submitted test and then realize that this is only the first of a series of articles they are working on ... so for now they hold judgment on AMD's newest product.

"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 Bulldozer FX Processor Benchmarks Leaked

Subject: Processors | October 2, 2011 - 09:29 PM |
Tagged: sandy bridge, Intel, i7 2600k, FX 8150, FX, cpu, bulldozer, amd

Intel has held the performance lead for several processor generations now, and while AMD is still technically in the game for home theater PC and budget builds, many enthusiasts have moved to Intel for gaming and high performance computers. Many of those people have also held hope that the chip manufacturer would eventually come back strong and maintain some level of competition in the industry. As we move closer to AMD's Bulldozer launch (which seems to have been confirmed for October 12th), enthusiasts and reviewers alike are clamoring to answer a long awaited question: "will Bulldozer give Intel a run for its money?"

According to website Donanim Haber, enthusiasts’ high hopes may finally be realized. The site has posted several benchmarks results that indicate Bulldozer is not only cheaper than Sandy Bridge, but performs on par with Intel’s top end Sandy Bridge chips. In many tests, the AMD FX 8150 CPU’s eight core performance matches the multi-threaded (8 threads, 4 cores) performance of Intel’s high end Core i7 2600k processor.

In the benchmarks that the site performed, the AMD FX 8150 was tested against the Intel Core i7 980X for 1080p gaming and the Core i7 2500k and 2600k for multi-threaded performance. In the graph shown above, the AMD Bulldozer CPU was roughly on par with the i7 980X, trading wins in some games and providing a similar level of performance in others. The AMD processor won in the Metro 2033 and Lost Planet benchmarks, but was slightly slower in Civilization V and F1 2010. In AVP and Batman (among others), the two competing processors saw equal results.

They also ran several benchmarks using highly multi-threaded programs to take advantage of the many-core designs of the AMD and Intel processors, including WinRar 4, Handbrake, 7zip, and wPrime 32M. The eight core AMD FX 8150 Bulldozer processor was tested against both an Intel Core i5 2500k and a Core i7 2600k. The AMD CPU came out ahead in 7zip, wPrime 32M, and Bibble 5.0. It was slower than the Core i7 2600k in the WinRar 4 tests and slower than both the 2500k and 2600k in the ABBYY OCR10 benchmarks. In the other tests, the AMD processor kept pace with or was only slightly behind the top end Intel 2600k CPU.

From the leaked benchmarks (which you can read here), AMD’s new Bulldozer CPUs have made an admirable showing. Should these benchmarks hold true, Intel will have some serious competition on its hands, something that the company has not had to deal with in a long time. Whether Bulldozer will result in price cuts or ramped up production on the Intel side remains to be seen; however, the results are not going to be easy for Intel to ignore.

Stay tuned to PC Perspective for more Bulldozer news in the coming weeks.
