A new report suggests that Apple is playing A9 chip makers Samsung and TSMC against one another in the lead up to the launch of new iPhones, attempting to extract last-minute price reductions for its next-generation processors. According to the report from Digitimes, which has a mixed track record regarding upcoming Apple products, Apple is requesting lower prices from both companies. Though TSMC is “inclined to refuse,” Samsung has agreed to discount the chips, offering Apple “almost-free backend services” in an effort to “grab the majority of A9 chip orders.”

The report suggests that Apple is leveraging the novelty of the FinFET chip manufacturing process to extract concessions from TSMC, which has relatively few FinFET chip orders from other customers. A claimed reduction in Apple’s demand from 30,000 wafers per month to under 20,000 wafers would leave TSMC to make up a significant difference between Apple’s original order and the Taiwanese company’s FinFET production capacity. The impact on Apple’s upcoming A9X, which was believed to be handled by TSMC, is unclear…

Buying a Mac is designed to be easy. Apple has a handful of different models, each generally available in good, better, and best configurations. You’re supposed to start with the specific Mac model that fits your needs, pick a configuration that has the price and features you want, and walk away happy with your purchase. (Better yet, do your research online and save money after ordering from Amazon, or use the product guides off to the bottom right of this page.)

One thing Apple tends to downplay are tech specs — important numbers and acronyms that nonetheless confuse many people. Look carefully on Apple’s web site and you’ll find that there’s a Tech Specs page for every Mac Apple sells; they’re the keys to making an informed Mac purchase that will be right for your current and future needs. My latest How-To is here to walk you through each of Apple’s specs with clear explanations, so you can understand what you’re about to buy. This Part 1 discusses the “big 5” Mac specs you need to know about, and Part 2 tackles the rest

Following the launch of Apple’s new Mac Pro earlier this month and some early deliveries arriving for customers, Other World Computing today posted a quick teardown of the machine (via MacRumors). We’ll have to wait for a full, in-depth teardown to find out specifics, but several images posted by OWC do reveal what appears to be socketed CPUs. In theory that means owners should be able to perform a DIY upgrade of the Intel Xeon E5 processors shipping with the new base configurations.  expand full story

There was much disappointment back in June when the new Mac Pro‘s CPU – the 12-core Xeon E5-2697 – delivered a surprisingly low Geekbench score of 23,901. It had been widely expected to break 30,000.

Some cautioned then that the score, based on a 32-bit build of Geekbench running on an early pre-release version of the CPU with a beta version of Mavericks, might not tell the whole story, and new tests by Tom’s Hardware on V2 of the chip appear to confirm this …  expand full story

According to a report today from SemiAccurate, a semi-accurate site that has been hit and miss on Apple rumors in the past, Apple has just bought into a chip fab plant, backing up recent rumors that the company could be moving to build its own CPUs.

Apple has just done something that SemiAccurate has been expecting for months and entered the fab industry. No we are not joking, Apple just bought into a fab, and not in a trivial way either.

The full report remains behind a paywall, so it’s unclear if the site mentions a specific company that Apple has bought into. The tags for the report, however, do list “UMC”, a hint that the company in question could be Taiwan-based chipmaker United Microelectronics Corporation…

A detailed performance test of a prototype Core i7 Haswell chip by tom’s Hardware suggests that it will offer a 7 percent to 13 percent performance gain over equivalent Ivy Bridge CPUs—a similar gain to that experienced with the move from Sandy Bridge to Ivy Bridge.


The integrated HD 4600 GPU experiences an impressive speed boost of almost 30 percent, but the website noted that this still won’t allow for comfortable gaming on HD monitors, so gamers will need discrete graphics chips.

While performance gains reached up to 75 percent in the case of some specific tasks, the gains for typical desktop applications are relatively modest.
