If you’re hesitant about updating to the recently-released OS X 10.9.3, there may be good news if you’re a recent Apple notebook owner.

Per French news site Mac4Ever and MacRumors, updating to 10.9.3 increases available VRAM from 1024MB to 1536MB, boosting the size of the shared memory, possibly to further improve 4K performance on the most recent Retina Display MacBook Pro and MacBook Air notebooks..

The change can be seen in the Graphics/Displays section of the System Report accessible via “About This Mac”. Apple has not yet updated its support page to reflect the new VRAM limits, continuing to list 1GB of system memory as the maximum. The update was also not mentioned in the 10.9.3 release notes.

The 10.9.3 update also included enhanced support for 4K displays and restored the ability to sync contacts and calendars between Macs and iOS devices over USB.

Finally, it’s been reported that some machines with HD 4000 graphics have seen a VRAM boost as well, namely the 2012 Mac Mini, which now has a maximum VRAM of 1024MB, up from 768MB.

If you’ve seen this improvement or any significant changes on your end since installing OS X 10.9.3, please let us know in the comments.

Christmas-GiftHere’s part 2 of my Gift Guide, which may turn into that “what I get when I return my Christmas gifts for credit” list, seeing as how it’s only 6 days until Christmas. The second half includes a number of gift ideas that I’ve stolen borrowed from some other gift guides because they are really good suggestions for things I’d like to get for myself. I’ll throw in a couple more of my own at the end.

Review: Budget Lightning cables from iSmooth (Updated)

LIGHTNING2MCABLEMAIN_mediumBefore I upgraded from my iPhone 4S to the new 5S, I wanted to be prepared. Unlike previous iPhone upgrades, I had to deal with the switch from the 30-pin to the Lightning connector which was introduced with the iPhone 5. Over the years I had collected a stash of chargers and cables as well as accessories, such as the Mophie Juicepack, which I had grown dependent on, and now had to replace. Not an inexpensive endeavor, especially with Apple’s premium price for replacement Lightning cables ($19-$29). Not expecting to find anything, at least not of great quality, I hit Amazon.com to see if there were some cheaper alternatives. After some exhaustive reading of reviews, I settled on cables made by iSmooth.

Chipworks continues examination of A7 processor, finds new architecture, quad-core GPU

There’s some cool stuff going on with the iPhone 5s’ new A7 processor.

Per an analysis published by Chipworks, the A7 contains assorted changes from the previous A6 processor, including the addition of a mysterious SRAM cell never seen in A-series silicon.

Continuing its comprehensive investigation of the new A7 SoC, which on Tuesday confirmed a 28nm manufacturing process, silicon experts at Chipworks are digging deeper into the processor’s major structures and overall design.

The firm notes in the report that the latest findings are currently just “best guesses,” as circuit extraction testing has not yet been performed to yield conclusive data.

Taking the caveat into consideration, one of the more interesting findings would be the “secure enclave” used for Touch ID fingerprint data storage that Apple discussed during the iPhone 5s reveal earlier this month.

Chipworks was unable to identify a given area it had noted, but guesses that a new SRAM cell located above the GPUs is a prime suspect as the rather large storage space is a new addition to the A-series lineup. Extrapolating the size of the memory block and comparing it with metrics of known technology, the firm estimates the SRAM module to have a density of about 3MB.

Moving to the CPU, the A7’s dual-core unit and accompanying memory, estimated at 1MB for L2 cache and 256KB for L1, takes up about 17 percent of the die area. Located across from the CPU setup is a quad-core GPU with shared logic, which accounts for 22 percent of on-die space.

A side-by-side comparison of the A7 and last year’s A6 show the chips’ CPUs do not share the same layout. The new A7 appears to be closer to a conventional automated design, which would be a departure from Apple’s most recent custom-architected A-series SoCs.

Aside from the above discoveries, the rest of the A7’s design appears to be carried over from the A6. Of note, the USB, LCD and camera interfaces are identical to those found in Apple’s A5, A6 and A6X chips.

Stay tuned for additional details as they become available.
