UPDATE:

HWC forum user Cowboy provides SKYmtl @ HWC some "hot top-secret 5850/5870" pics taken from a Canadian subway station where he met an unnamed Ati insider!!!! The 5870x2 has the early protoype cooler, and there is a 5850x2 also. There is space for 2x 8-pin on the pcb. Another shot shows the first 5870 cooler without the red stripe! It also confirms Eyefinity works via 2x dvi-d & 1 x mini-dp, and there is a full slot exhaust. He should have bought the 5870x2 as it would be an extremely rare one NICE ONE CANUCKS!
















Remember these early prototypes?





well....

[PSU]Seasonic X-Series Go for Gold!

Seasonic PSU is 90% efficient, silent below 20% load










COMPUTEX — Power supply efficiency is the latest craze, and the sheer number of 80 Plus-certified PSUs at Computex is a clear testament to that. Seasonic may have the most unique one, though.

The firm's new X-Series power supply series include 650W and 750W models, both of which have 80 Plus Gold certification. That means the unit reaches a 90% efficiency level when it's loaded to 50%. (Efficiency at 20% and 100% loads is a lesser but still impressive 87%.)

Even more interesting is the X-Series internal design, which looks surprisingly bare compared to traditional units crammed with heatsinks and capacitors. Seasonic wouldn't let us take pictures, but it uses a second circuit board stuck right up against the modular connectors at the back to reduce the number of wires inside the casing. Also, presumably, the high efficiency should mean the internal components generate less heat, which in turn requires less cooling.

Thanks to that design, Seasonic says the cooling fan inside an X-Series PSU just won't switch on until the unit reaches a 20% load. Now, the company also told us temperature will determine the fan speed, so the fan may not turn off in a particularly cramped or poorly ventilated system. Still, Seasonic designed the X-Series to be entirely passively cooled in a regular PC at sub-20% loads. And that's without massive heatsinks poking out the back.

Seasonic expects X-Series power supplies to be available at online retailers in late July or early August.

Ubuntu 9.10 boot optimizations: 5 second startup with an SSD


Ubuntu 9.10 boot optimizations: 5 second startup with an SSD

Canonical has announced the availability of Ubuntu 9.10 alpha 6, the final alpha release before the transition to beta testing. Ubuntu 9.10, codenamed Karmic Koala, introduces a number of important architectural improvements and also improves boot performance, especially on computers with solid state hard drives.

Earlier this year, Canonical revealed plans to significantly optimize boot performance. It aims to deliver 10-second startups for the Ubuntu 10.04 release, which is due in 2010. In the latest Karmic alpha, the team has already taken some important steps toward achieving this goal. Their roadmap indicates that 25 seconds is the target for Karmic, and the reference device used to benchmark progress is the Dell Mini 9 netbook. We did some testing of our own to see how the OS is coming along.

I installed Ubuntu 9.10 alpha 6 on a Dell Inspiron 1420n, the Ubuntu laptop that I reviewed in 2007. I conducted extensive startup performance testing and used the bootchart utility to measure the results. My average boot time was 22 seconds, with Xorg starting roughly 13 seconds into the boot process.

Users with solid state drives will see a far more dramatic improvement in boot performance. Canonical external developer relations coordinator Jorge Castro (a former Ars Linux contributor) supplied us with a boot chart from his computer, which has an SSD and boots Karmic alpha 6 in only five seconds. If you examine his chart, you will see that Xorg comes up in only two seconds.

One of the most significant technical factors contributing to awesome SSD boot performance is the inclusion ofsreadahead, a system service that uses prefetching to load data that is used by the boot process before it is needed. It will also cache the prefetched data and store it so that it can be used during subsequent boots, but it's less effective on conventional hard disks where seek latency introduces some challenges. Ubuntu developer Scott James Remnant explained some of the technical nuances in a mailing list post a few months ago.

In Ubuntu 6.10, which was released several years ago, Canonical introduced a new event-based boot daemon called Upstart to replace the traditional System-V init. One of the primary advantages of Upstart is that it is highly conducive to parallelizing the boot process. In previous versions of Ubuntu, Upstart has largely been used with traditional init scripts. Karmic is the first version where it's really being used to its full potential. On an interesting side note, Upstart has been gaining a whole lot of traction in the mobile space and is used in both the Palm Pre and Nokia's upcoming N900.

Not just boot time

In addition to the improvements to boot performance, a number of other significant enhancements are also featured in Ubuntu 9.10. This is the first Ubuntu version to use GRUB2 and Ext4 by default. Another major change is the adoption of DeviceKit, which will displace HAL, the previous hardware abstraction layer. Pidgin has been replaced in favor of Empathy, a new instant messaging client built on the Telepathy framework that has been adopted by the GNOME community. Client software for Canonical's Ubuntu One cloud storage service is also included by default for the first time.

Ubuntu 9.10 alpha 6 is available for download from the Ubuntu web site. According to the release schedule, the first beta is due on October 1, and the final release is coming on October 29.

ATI Hemlock (Radeon HD 5870 X2) Pictures



ATI Radeon HD 5870 SIX/Eyefinity edition on the right, the beefier HD 5870 X2 on the left. Note that both cards require 6+8 pin PCIe connectors, as opposed to 6+6 pin for the regular HD 5870.





The full length of Hemlock from behind - all 12 inches of it. Since this is the longest consumer card ever - you might want to check for space inside your case if you are planning. The single crossfire connector is visible - allowing quad-CrossfireX. This picture also pretty much crushes rumours of an MCM single package Hemlock chip. However, it is interesting to notice how close the two Cypress dies are to each other. This could suggest a possible relocation of the PLX chip - or perhaps a new interconnect.


Hemlock is scheduled to be launched in one month's time at a rumoured $499. For more information, do read our earlier report on AMD's demonstration.

Asus Voltage Tweaks Radeon HD 5870 Fast up 38%



Obviously, both GPUs support Windows 7 and DirectX 11, and both are built on 40nm process technology and GDDR5 memory. Each single card can run up to three displays (that's Eyefinity for ya!), and better still, each one comes bundled with DiRT 2, a highly anticipated DirectX 11 title. If you're curious about how that "voltage tweaking" really works, here's the deal: It enables users to raise GPU voltages from 1.15V to 1.35V and from 1.088V to 1.4V respectively, boosting GPU and memory clock performance from 850 / 725 MHz to 1035 / 1050 MHz and from 4800 / 4000 MHz to 5200 / 5200 MHz respectively. Evidently Asus doesn't expect the factory overclocking tool to harm any system parts, and there's no need to mess with BIOS settings in order to make it all work. Sadly, Asus isn't coming forward with pricing just yet, but we'd expect these in stores very, very soon.
