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."

Earlier today Lucid (LucidLogix), the company behind quite a few GPU virtualization technologies, announced yet another piece of GPU virtualization software. This time; however, instead of wrangling as much performance as possible from multi-GPU beasts, this technology- codenamed "XLR8"- is aimed at the mobile market of tablets, smartphones, and laptops with integrated graphics. Such products are powered by integrated GPUs in AMD's APUs and Intel's Sandy Bridge and Ivy Bridge processors, and by the GPUs in mobile SoCs (system on a chip) like Nvidia's Tegra and ARM's Mali graphics processors. XLR8 uses "unique CPU multithreading" to feed the mobile GPUs as efficiently as possible.
According to Lucid, many of the PC graphics issues are magnified when it comes to embedded GPUS including visual tearing, pipeline inefficiencies, power management, and artifacting. Offir Remez, president of Lucid further stated that most of the big, popular PC games have playability issues on mobile platforms and on computers with integrated graphics. "If it's got a GPU, we can improve the end user experience."
The company further expanded that the XLR8 technology works by disabling unnecessary and redundant processes in addition to "unique multithreading" to improve system (gaming) responsiveness up to 200 percent. The XLR8 software monitors battery drain and power draw while shutting down background processes to increase CPU frame generation and minimizing redundant GPU rendering processes.
If this sounds a lot like marketing speak, it certainly does. On the other hand, Lucid has been able to push some useful virtualization technology into desktops, so maybe mobile platforms are just the next step for the company. The company is currently demonstrating the XLR8 software in private at CES and is being tested by hardware partners. Mobile SoC are getting faster and more powerful, and on battery powered devices there is always room for efficiency improvements. Once reviewers manage to get their hands on some actual hardware, and XLR8 is past the concept/testing stage you can bet that people will have a better understanding of what exactly XLR8 is capable of.
