That’s not much but remember: the processor is now clocked 15 percent slower than before. So generally we can expect a tiny lift in processor speed, in the order of 5 percent. Then it was from 108 to 115 cb points in R15’s single mode, and from 520 to 564 cb points in multi. Single-core mode rose from 1.28 to 1.34 points, and multi mode from 6.04 to 6.23 points in R11.5. Looking at Cinebench with its graphics rendering and CPU tests, both the familiar R11.5 and the latest R15 versions, we saw a similar fractional increase in CPU performance. Compare this with 3124 and 12,044 points for last year’s MacBook with 2.3 GHz Core i7, and we see a inconsequential 0.8 and 2.2 percent changes. In the Geekbench 3 test of processor and memory performance, it averaged 3148 points for a single thread and 12,306 points in multi-core mode. New 13-inch Retina MacBook Pro (early 2015) preview.ĭespite the slower clock of this entry-level version – 2.0 GHz against the 2.3 GHz of the first Retina Mac, and 2.4 GHz of its February revision – this MacBook Pro does run faster than before. Update: Apple unveiled new MacBook Pro models at itsĩ March 2015 press event. The real coming-out party for Intel graphics required a crucial update from Apple though – namely the unlocking of OpenCL to work on integrated graphics processors, now enabled in OS X 10.9 Mavericks. Once a recipe for slow-motion slide shows in place of fluid gaming video, Intel’s integrated graphics may finally have come of age, if our test of the recent 21.5-inch iMac are any indicator. It’s still not exactly cheap, but the £1699 entry-level MacBook Pro (15-inch, Retina, Late 2013) relies entirely on the Iris Pro graphics solution that’s embedded within a Core i7 quad-core processor. And more recently, we’ve seen low-power Intel graphics included too, with automatic switching that powers up the full-bore graphics only when relevant applications are running. The Verge has reached out to Apple for comment.Every 15-inch Apple laptop since the PowerBook G4 has included either an ATI (AMD) or nVidia graphics processor. If you’re thinking about updating, it may be wise to give it a few weeks while the bugs are worked out. Given the black screen problems some users have been having, perhaps the download issues were for the best. The server issues also made it impossible for some users to install the update, with the OS showing an installation error as people tried to launch the installer. High-demand for the update seems to have slowed Apple’s servers to a crawl, which has led to a widespread slowdown of newer Macs due to a little-known feature that verifies with Apple that apps don’t have malware before each time they run. There’s no clear indication of what could be causing the problem, and simple ways of fixing it - like resetting NVRAM or booting in safe mode - either can’t be accessed or don’t resolve the issue, users have said.īig Sur has had an unusual number of launch issues. The issues were spotted by MacRumors, which saw complaints of frozen laptops in its forums, on Reddit, and on Apple’s support site. Owners of other Macs have reported Big Sur installation issues, too - and some say they’ve been able to fix those issues - but those two models of MacBook Pro seem to be having the most severe problems for now. The issue seems to be most common on late-2013 and mid-2014 models of the 13-inch MacBook Pro. The macOS Big Sur update has been causing some older MacBook Pros to get stuck on black screens during installation, with no way that users can find to fix it.
