AMD's new AM2 platform launched

Internet News

Fifteen processors were launched on the new AM2 platform by AMD today, ranging from the new flagship FX-62 at $1031 all the way down to a $77 Sempron 3000+. The official announcement is in AMD's web press room, but news, reports and reviews of the AM2 processors and platform are all over the web; a few of the sites are linked below. AMD's PR department made sure that all the popular hardware review sites obtained samples of FX-62 or X2 5000+ processors along with a new Asus M2N32-SLI Deluxe motherboard with the new nForce 590 chipset, and Corsair 1066MHz DDR2 RAM.

AMD News: T64X2, Efficient Processor Roadmap, K8L Preview

Internet News

AMD just released information about Energy Efficient Desktop Processors in the upcoming new AM2 socket, the long awaited 64-bit Turion 64 X2 dual-core mobile processors, and a sneak preview of their next-gen K8L processor technology. Click on read more for more info.

Thermal Load Calculator by Innovatek

Internet News

PC-Water-Cooling.com sent us word of a Thermal Load Calculator by Innovatek which works out how much heat is produced by a standard or an overclocked PC. The page is in German but the calculator is intuitive. It looks much more accurate than 99% of all such power calculators on the web, and should be fine for "sizing" PSUs if all the pertinent data is correctly entered. Only the Northbridge vs Northbridge und Mosfets choice under Motherboard give pause; surely you cannot separate the motherboard VRM from the NB in any calculation of motherboard power draw? This is the only feature that seems suspect.

Run Windows XP on iMac with Boot Camp

Internet News

PC World reported, "It works. Impressively well. With games, even. That's our first impression of Windows XP running under Apple's [beta version of] Boot Camp on our 20-inch iMac. And that's more than you could say a couple of days ago about the promising-but-hacked-together WinXPonMac effort."

Desktop Core Duo Products Coming Soon

Internet News

Apple's new iMac may have been the first to use Intel's new power-efficient Pentium-M derived Core Duo on a desktop PC, but they certainly won't be the last. Joining AOpen with new Core Duo/Solo (and Pentium M) products are Asus, Shuttle, ECS, MSI and Gigabyte. It seems clear that Intel is successfully marketing the new low-power processors to the mainstream desktop/small server market. Thus far, however, Intel's major system integrator partners (Dell, HP, etc) are only featuring Core Duo processors in notebook PCs.

AOpen: i975Xa-YDG and i945GTm-VHL Core Duo motherboards; mini-PC MP945
Asus: N4L-VM DH Core Duo Viiv motherboard
Shuttle:
XPC X100 Complete SFF Core Duo PC
ECS
: PF23 Crossfire-compatible and 945G-M3 Viiv motherboards
MSI: P1-104A2M P-M server and 945GT Speedster-A4R P-M motherboard
Gigabyte: A963 Core Duo/Solo MiniPC

Then there are all the mini-ITX boards for Core Solo / Duo:

Commell LV-677 (m-ITX)
AOpen i945GTt-VFA
DFI G5C100-N
Freetech P8F189
IBASE MB877
Kontron 986LCD-M/mITX
MSI MS7265 (not confirmed)

From IDF: Acoustic Optimization for Desktop Platforms

Internet News

Attendance at the Spring Intel Developers Forum last week resulted in many new contacts for SPCR. Among the most interesting were Intel engineers in a thermal / acoustic division who provided information about new R&D efforts in this area. One result is a White Paper, which was provided to SPCR for direct distribution to our readers: Acoustic Optimization for Desktop Platforms (2mb PDF).

This is probably not the first document from Intel to deal with PC acoustics, but it is the first we've seen in a long time. Much of it focuses on BTX platform advantages, but it touches on many aspects of acoustics measurement and analysis that is of relevance to anyone interested in low noise computing. Most fascinating to us is the research done on Acceptable Acoustic Levels, which involved both group psychoacoustic polling as well as ambient noise measurements in four countries. We are planning an in-depth look at this paper in the near future.

PSU Load Balance Critical in Dual-Vidcard Systems

Internet News

Dedicated SPCR readers know from our PSU Fundamentals and Power Distribution within Six PCs articles that modern PCs draw the vast majority of power from the 12V line of the power supply. What's less well known is that internal interactions in most power supplies impairs the capacity to deliver high power into 12V when the 5V and 3.3V lines are too lightly loaded. ExtremeTech has an interesting article illuminating this issue in both technical and practical aspects.

Mobile SATA HDD Roundup

Internet News

The Tech Report also ran a 2.5" Serial ATA hard drive round-up comparing a quartet of mobile drives -- that we've already reviewed individually over the last few months. Their acoustics analysis falls short of our standards, but the performance tests make for interesting reading. (There's not even a hint that you might consider one of these for desktop PC use.)

Another Turion 64 vs Pentium M comparison

Internet News

Yesterday, the Tech Report posted an article comparing the performance and power efficiency of the AMD Turion 64 ML44 (2.4GHz / 1mb cache - rated at 35W) and the Intel Pentium M 760 (2.13GHz / 2mb cache - rated at 27W) -- this time, in a desktop system. This comparison is of interest to any one who's interested in the coolest, lowest power dissipation desktop system. It's too bad that the closer matched Turion MT40 (2.0GHz / 1mb cache - rated at 25W) was not used instead. The price / performance analysis could also have been more fairly and comprehensively tackled.

New Arctic Cooling VGA coolers at InsaneTek

Internet News

A new site called InsaneTek has just posted a review of the entire line of new VGA coolers from Arctic Cooling. As regular visitors are probably aware, Arctic Cooling's VGA Silencer is strongly recommended by SPCR. Its prime innovations are a big waterwheel style fan combined with a large cooling fins and a design that pushes the hot air from the VGA card out of the case instead of spewing it all around the case. It is not too noisy at standard speed and has a switch to slow the fan to a whisper quiet mode. The downside is that the original fits only certain models of the ATI 9000 series and nVidia GF3s.

The new AC VGA cooler line maintains the same key features in a somewhat more streamlined design, adds clever cooling for the VGA RAM, uses copper in many models, and is divided into two series: NV silencer 1 through 5, and ATI Silencer, 1 through 4. The nine models cover just about every current mainstream VGA card. One change is that most models now feature temperature control for the fan with different top speeds for various models. InsaneTek's review is quite good in most ways and surprisingly complete despite its brevity, but does little more than just touch upon the acoustics. Still definitely worth a read.
