The good news is that the new 2011 MacBook Pro notebooks are out and they are generally considered speedy and awesome.

The bad news is that Apple may have been aware for some time of the problem of new MacBook Pros crashing under heavy loads. According PC Pro magazine, Apple appears to have deliberately turned off Turbo Boost for the top-end 13″ model (with a dual-core 2.7 GHz Intel Core i7-2620M processor) when running Windows under Boot Camp.

PC Pro originally thought that Turbo Boost had been disabled under OS X as well, but then tests performed by AnandTech showed that the feature was only disabled under Windows. “We first noticed a problem when the benchmarks finished five full runs and the results popped up on screen: the times taken to complete several of the most intensive tests were rising with each run” says PC Pro. “This would suggest an overheating problem, so we ran a temperature monitor to find out how hot this Sandy Bridge CPU was getting.”

In fact, the CPU was reaching around 93°C — almost 200°F. “93°C is not necessarily too high for a modern CPU, but it is the root cause of the bigger performance problem.” The magazine went on to state that it was sure the processor isn’t turning off Turbo Boost dynamically, since it didn’t work at all during their week of testing no matter what the CPU temperature was. Also, the cheaper model with the i5 processor did use Turbo Boost, as did the i7 model under OS X.

After measuring the underside temperature of the top-end model at 60°C — 140°F — they conclude that it might actually be a better deal to buy the cheaper 13-inch MacBook Pro. If Turbo Boost is disabled on the higher model, the lower-end version will actually run Windows faster than the more expensive MacBook Pro.

Stay tuned for additional details as they become available.

iPad 2 set for international launch on March 25th

You can’t find it in the United States, so that’s no reason not to introduce it to the rest of the world.

Per TechRadar.com, despite continued sellouts of the iPad 2 in the U.S., an Apple spokesperson has confirmed that the international launch of the touchscreen tablet will proceed as planned on Friday, March 25.

“Everything that is on [Apple's U.K.] website still holds true; the website says 25 March and that’s when it’ll be,” an Apple spokesperson told TechRadar.com earlier this week.

Rumors that Apple would delay the international launch of the iPad 2 were fueled last week by immediate sellouts of new shipments of the device and long lines that continued in the week after launch. Last week, analyst Brian White of Ticonderoga Securities questioned whether Apple would be able to produce enough iPad 2 units to launch in more than two dozen countries this Friday after checks to several key Apple Stores.

Also stoking speculation of iPad 2 delays were reports of supply chain disruption caused by a massive earthquake in Japan that took place earlier this month. Piper Jaffray analyst Gene Munster told investors last week that the production status from Apple’s Japanese-based component suppliers remained unclear, with many partners unable to accurately quantify the extent of their damage.

Late last week, a report from iSuppli identified five components in the Pad 2 that are likely sourced from Japan: NAND flash from Toshiba Corp., DRAM made by Elphida Memory Inc., an electronic compass from AKM Semiconductor, a touchscreen overlay glass likely from Asahi Glass Co. and a system battery from Apple Japan. The report noted that while some of the suppliers’ facilities were undamaged, “delivery of components from all of these companies is likely to be impacted at least to some degree by logistical issues now plaguing most Japanese industries in the quake zone.”

Apple announced last week that it is delaying the launch of the iPad 2 in Japan “while the country and [Apple's] teams focus on recovering from the recent disaster.”

The iPad 2 is scheduled to go on sale March 25 in Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Mexico, Netherlands, New Zealand, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the U.K. According to Apple, launch dates and pricing for further international launches will be announced at a later date.
