Want a hex-core? AMD offers its alternative to the i9!
The battle of the titans has begun, with the AMD side taking the form of a new processor - codenamed Thuban - which is based on the Phenom II, but with 6 cores. This response by AMD to Intel's Core i9 Gulftown should appear sometime in 2010.

Also on the list of good news is the fact that Thuban will be compatible with AM3 and AM2+ motherboards, provided your motherboards BIOS has been updated to support the new processor.

A small photo of the beast:



It's a safe bet that the CPU will not win the fight against the i9 Gulftown, at least not in terms of raw power, as it lacks hyperthreading technology. But cons aside, the PPD/(£ or $) ratio may be of interest to folders, as AM3 motherboards are relatively inexpensive compared to their Socket 1366 counterparts. However, it is likely that Intel will reduce the price of the i9 to counter AMD's latest move.

See you in 2010 for the battle of the Phenom II X6 vs Core i9!

Update on New Cores and Clients

By , the in Folding@Home Project - No comment
Stanford has been very busy with new cores and clients for FAH, and Vijay Pande has published some new details.

The new announcements concern:
  • The two cores for SMP2
  • The Protomol core and a new MD method, NML
  • GPU3: OpenMM and OpenCL


The full story can be found here.

GT300 "taped out"

GT300 "taped out"
Fudzilla has announced that the GT300 chip from nVidia is considered "taped out," which means that the current revision of the chip is considered ready for mass production. This announcement is therefore the start of mass production of the chip and means it could be on sale within 6 weeks (the normal timescale for semiconductor manufacturers).

To fold with this monster, contact your bank manager at the soonest opportunity ;)

Breaking news: HD5800 Performance and OpenCL's future

Breaking news: HD5800 Performance and OpenCL's future
mhouston, AKA Michael Houston - the developer of the ATI GPU2 core - has just spoken about the future folding performance of the Radeon 5800. He has already tested the card, and the expected benefits are as follows:

  • Up to 50% faster performance on large WUs (not distributed as of yet)
  • A small performance increase on current small WUs


Obviously, these figures are only realised with certain optimisations enabled, since the core is optimised for the Radeon HD4800 and 800 vector processors. However, it seems that Michael no longer wishes to change the current core.

The current core - based on CAL / Brook+ / Stream - has become impossible to maintain. The CAL (Compute Abstraction Layer), which is a layer of abstraction between the application and hardware, is not his work; when new hardware comes out, the core is further optimised for it. For Michael, the future of folding is on ATI's OpenCL, because the layer is much more mature. He wants to take over the development of a new core built on this new API, to avoid having the problems that have plagued the current core.

The direct consequence is that nVidia and Intel could also be supported in the future.

We aren't able to say whether work has yet begun, but we follow new developments with anticipation.

Intel unveils silicon wafer manufactured on a 22nm process
The IDF (Intel Developer Forum) is a stage for Intel to demonstrate its upcoming technology. In amongst the orgy of power of certain demonstrations, it is the new smaller process that attracts our attention. Along with leaks of Core i3 at 32nm, Intel showed a silicon wafer manufactured on a 22nm process.


This 30cm diameter cake has the following characteristics:
  • 22nm
  • 364Mbit storage
  • 2.9 billion transistors

Intel is not lagging, the future for CPUs looks good!

Ubuntu 10.04 to be called "Lucid Lynx"

Ubuntu 10.04 to be called "Lucid Lynx"
Mark Shuttleworth, the charismatic founder of Canonical, the company which maintains Ubuntu, has announced officially at UbuCon at the Atlanta Linux Fest 2009 what the next LTS (long term support) version of Ubuntu will be called.

Hopefully the Mac fanboys will not be too offended, as the Ubuntu team have "stolen" a cat for the name, as the spring version of the distribution will be called Lucid Lynx. It is a fast and ferocious animal if not one of the most impressive, which may well be the tone for the OS.

The main changes are that it should (finally!) achieve the 10 second boot time that the two previous versions strove for. However, the Ubuntu store is more likely to attract attention as for the first time it will be possible to make an online purchase of software through the interface.



Houston, we have a new Ubuntu!

Storage@home needs you!

Storage@home needs you!
Adam Beberg, the creator of the Storage@home project, needs you!

SAH is currently in a phase to see if the mathematical model devised by Adam is consistent with measurements made by the monitor program (currently v1.03). Currently, here are the contributions:

OS CPU Hosts Memory (in MB)
Win32 x86 51 123862
Win64 x64 26 160420
MacOS X x64 6 26624
Linux x86 10 16726
Linux x64 21 91134
Totals: 114 418766


To validate the model, Adam has estimated it would need 1000 contributors before the deadline of this phase of the project (September 30th), so please, join Storage@home!

All information on this project, including the installation procedure, can be found here: Storage@home.

A2 SMP projects fixed.

By , the in Folding@Home Project - No comment
The repairing and rebuilding process of the SMP A2 WUs affected by folding on 1 core bug is now completed.

Simulations of the affected trajectories should now be possible and the number of “CoreStatus FF (255)” errors (the sign of this bug since 2.10 core) that you might encounter would be drastically reduced.

About core 2.10 performances on dual core processors, you’ll have to get used to them. :( We hope that performance will be back to the previous level in future core updates. My advice, if you can, is to replace your dual core VMs with native Linux or quad core VMs, waiting for better days.

Athlon II X4 620, 4-cores CPU for less than $100

Athlon II X4 620, 4-cores CPU for less than $100
AMD has just released their Athlon II X4 620 and 630 processors clocked at 2.6 and 2.8 GHz and built with the Propus core, a Phenom II (Deneb) without L3 cache.

These processors aim at AM3 and AM2+ platforms. They are rated for a 95W TDP and feature 4*512 kB of L2 cache.

If you look at pure performances, the 620 model sold at $99 performs like an Intel Q6600. This processor is the cheapest in his area, and has no direct competitor.

AMD could have made better choices regarding the power consumption of this processor if they had decided to provide it with a VID lower than 1.4V (1.12V idle/1.396V under full load), which is definitely inordinate. 620 model is indeed able to operate at his stock clock with only 1.15V (0.864V idle/1.152V under full load), which leads to 30W cut in power consumption of the entire machine. We don't know if AMD decided to indirectly favor overclocking of these processors, but the test sample has been able to easily reach 3.2 GHz with his 1.4V voltage.

PCINpact published (in French) a series of 3 small articles about these processors that you might want to read if you wish to learn more :

More details about Intel Turbo Mode

More details about Intel Turbo Mode
Because Intel doesn't use the same Turbo Mode across the processors featuring this function, a little summary might be useful.


Click the image to enlarge.


To decipher this table, the numbers in behavior ("Comportement") columns shows the number of Bclock added by Turbo Mode (in other words, the number of increments to the basis CPU multiplier) in a 4-cores, 3-cores, 2 cores and 1 core configuration. For instance, with a CPU using a 20 multiplier with a 1/1/1/2 behavior, maximal multipliers will be 21 for 4-, 3- and 2- cores and 22 for 1 core.

I hope this situation is now clearer to choose your future CPU. Keep in mind that Folding@Home will fully utilize you CPU, so you have to look at the 4-cores column to know the maximum frequency you'll get in this situation.
