Apple’s MacBook Pro with 16 GB RAM

MacBook Pro
It was recently rumoured that Apple’s MacBook Pro line-up is likely to receive an update and a leak suggesting that all 15 inch models will be standard with a 16 gigabytes of RAM.

 As per French website MacG citing confirmation from a reliable source, the new 13 inch MacBook Pro with the Retina display is presumed to be identified as `J44a’, model while the new 15 inch model is said to be as `J45a’.

Beside this no other information has been on the new high end MacBook Pro modes though in-store signage from China was rumoured, that the new 15 inch models will have slight increase in CPU speed which comes with 16 gigabytes of RAMs in all the models.

The advertisement also conveys that the models would be coming at the same price as the prevailing offerings. This update on a scale from mild to wild is on a mild side wherein the clock speed is improved by 100 MHz to 1.4 GHz giving it a negligible and a modest performance.

 The overall performance of graphics remains the same,though the Intel i5 processor which is used by Apple in the refreshed MacBook Air has similar graphics which operates at the same earlier speed.

Broadwell CPU to hit the Market

Other specification remain unchanged namely Thunderbolt, USB 3.0, 802.11ac Wi-Fi and Bluetooth 4.0. With regards to memory and storage it remains the same and the MacBook Air accommodates 4 GB RAM as well as 128 GB flash storage in its base configuration.

The battery life is at an estimated nine hours between charges for the 11 inch model, while the 13 inch model remains at12 hours. Apple states that the power efficiency for iTunes movie playback has done good improvement with the updated CPU. Intel has promised its first Broadwell CPU will hit the market before the end of the year but speculations are on whether they would be arriving in time or in enough capacity in order to power any new Macs.

Apple had launched a new $1,099 Mac in June and had reached a new price point with low end processor. Moreover the company had also dropped the price in April on its MacBook Air range with a new entry price of $899, with an increase on the speed of its processor by 100 megahertz.

Redesigned MacBook Air

With plans to debut the new 12 inch MacBook model this year together with Retina display it is suggested that this model could be a redesigned MacBook Air and also the first to feature a pixel packing screen while others are of the opinion that Apple could be waiting for Intel’s Broadwell CPUs to be launch the said updated model.

The codename `Broadwell’, is used to refer a 14 nanometer die shrink of Intel’s previous 22 nanometer Haswell architecture and according to Intel it is a new smaller design, bringing about a 30 percent cut in power consumption and simultaneously offering the same horsepower.

The Retina MacBook Air of 12 inch model is rumoured to sport a fan less design that may need cooler with efficient CPUs. It is also expected from Apple to achieve an exceptionally thinner version design along with new click less trackpad and few inputs and outputs.

iPad, MacBook Pro: minor revisions until something better?

Apple Store closures expected to succeed at a steady pace in the coming days. The ball will start today with the arrival of new MacBook Pro. In terms of innovations, this new range is presented as an incremental update, which should be distinguished by the adoption of SSD arrays, generalized processor Core i and the arrival of the famous port Thunderbolt. But to iLounge, the best is yet to come. The next generation expected for 2012 should be a major revision with significant changes in terms of design. One thing is certain, it is not shortage of ideas to Apple (read: The future of the MacBook keyboard but will not with sensors).

But the most interesting revelations concerning the iLounge iPad 2. Lately, there have been lots of rumors going in all directions; some left waiting for this model would be commercially available in June, while others argued that the initial production of tablets is less than expected.

For iLounge, there is some truth behind these rumors, and Apple has had to readjust his plans.

The site cannot say whether Apple would respond to the problems encountered, we have the right to a minor revision of the device until better in the fall. iLounge mentions the possibility of an iPad 1.5 which could still be called iPad 2 but did not have all the features originally planned for this model. The Cupertino Company would deal with production problems in the short term and give a little air. To our colleagues, the situation resembles that Apple had known at the launch of the iPod touch 3G, whose camera was withdrawn at the last minute due to production problems.

Mac Book Pro 13 "Core i7: The Turbo Boost function well

The 2.7 GHz Core i7-2620m team that the Mac Book Pro 13 "high-end mobile chip with the highest frequency available in the Intel catalog. It may even reach 3.4 GHz on a heart through the turbo boost, but Apple has apparently it off this feature to avoid overheating.

The Cupertino Company is yet to promote this function on the product page of Mac Book Pro, clearly indicating the frequency of 3.4 GHz that only the Core i7-2620m can be achieved in the current range. PC Pro has never yet managed to achieve this frequency in these tests, the processor remains hopelessly nailed to 2.7 GHz. Core i7-2720QM Mac Book Pro 17 "has no trouble reaching its maximum frequency of 3 GHz, so its four cores are at 95 degrees.

That's about the same temperature reached by the two cores of the Core i7-2620m Mac Book Pro 13 "at full speed to 2 GHz. This temperature is certainly high, but rather common, however, can only imagine the Turbo Boost, the processor could blithely exceed 100 °, temperatures this time potentially problematic. The English site therefore advances the hypothesis that Apple has disabled the Turbo Boost on the chip to avoid overheating. Notebook Journal (via) confirms this hypothesis: their copy is even temporarily increased to 798 MHz time to control its temperature.

Even without turbo boost, the Mac Book Pro 13 "Core i7 is a very fast machine. The question is whether Apple disables the default Turbo Boost, or if Mac OS X disables the fly: it will be difficult to know, rise in mean temperature rise mechanically. Having ourselves a Mac Book Pro 13 "Core i7 at our disposal, we will try to verify this behavior: we will update this article accordingly.

[UPDATE] Our own tests show that the Turbo Boost is indeed active on the Core i7-2620m Mac Book Pro 13 ". On two hearts, the incidence rises to 3.19 GHz (multi-core optimized implementation), so that it goes up to 3.33 GHz on a single heart (non-optimized implementation; Turbo Boost 2.0 is supposed to extend the "boost" Yet, we observe that the frequency goes down enough quickly, in very small increments (Intel explained that Core i7-2620m had 7 frequency ranges between 2.7 and 3.4 GHz).

The falling speed of the Turbo Boost seems to be correlated to temperature: the "boost" is much better during the first tests (when the processor runs at about 80 °) during the following (the processor then proceeds to over 90 °, with a peak at 97 °). It seems that Mac OS X and / or processor finely monitorent frequency to avoid overheating: it is again a function of Turbo Boost 2.0. Even in influencing the speed of the fans for the processor to overheat (remaining under the 110 ° measure), we observed no deactivation of cores or drastic fall frequency to avoid overheating.

In short, it seems that this processor is behaving as it should, with a much finer granularity of the "boost". PC Pro Notebook Journal as a tool used by Intel under Windows to test frequency: perhaps he is assigned a bug, or maybe the management of the Turbo Boost this particular model of processor is different ( or faulty) on this platform.
