Part is likely to be the PowerVR Series6XT GX6650, running at 1.4GHz
An analysis of the claims of Apple and leaked benchmarks with regards to the graphics performance and technologies in the new A8 chip that powers the iPhone 6 and iPhone 6 Plus indicates that Apple has likely moved to a new PowerVR GPU. The most likely candidate is the six-core PowerVR Series6XT GX6650 made by Imagination. Apple is also likely using a revised version of the Cyclone architecture, first used in the A7, to manage graphics processing.
Scores compare to previous dual-six-core Mac Pro benchmarks
On Friday, Geekbench published new processor scores for what appears to be a legitimate new Mac Pro model that utilizes eight cores on a single processor. A previous score from the unreleased 12-core Mac Pro appeared back in June -- suggesting that Apple is planning on releasing more than one model when the redesigned workstation is finally premiered. Though the scores of the two models can't be directly compared due to technical differences, the eight-core Mac Pro solidly beats current eight-core Mac Pros.
Around 70 percent faster than Core2Duo models
The first benchmarking tests are in on the new 2011 iMacs, and early results show a fairly consistent 25 percent improvement across the board over the previous models, and a 70 percent average improvement over the last of the Core2Duo iMac models, Primate Labs reports. It should be noted that the company used its own Geekbench 2 to obtain their results, which does not measure video card or storage improvements, being limited to just processor and RAM performance.
Parallels particularly strong in graphics and 3D
Parallels Desktop v6 was found faster than VMWare's Fusion v3.1 in 84 percent of more than 4,000 general benchmark tests conducted by MacTech Magazine, the publication announced, owing mainly to much more robust and faster graphics and 3D, an area where -- tested separately -- Parallels was found to be faster 92 percent of the time over its rival.
27-inch iMac core i7 bypasses some Mac Pros
Primate Labs has updated its Mac Benchmark chart, adding recent Macs to the list. The chart is a compilation of Mac-based performance scores generated from user-submitted Geekbench results. The comparison uses results from standard Macs instead of modified or overclocked systems. Numerically it uses a 1000-point baseline set to a Power Mac G5/1.6GHz machine.
Benchmarks - Snow Leopards
Apple's latest release, Mac OS X 10.6 Snow Leopard, has been benchmarked with positive results by normally Linux-focused Phoronix.com. The test suites cover over 100 profiles (only 60 were used in this round due to Snow Leopard incompatibilities) that can be applied to both Linux and Mac OS X, ranging from games to video playback and encryption tests. The tests cover two Mac setups, an older 1.83GHz 32-bit EFI Mac Mini with an Intel graphics processor and a newer 2.0GHz 64-bit EFI Mac Mini that supports OpenCL through its GeFORCE 9400M graphics processor. Mac OS X 10.5.8 and Mac OS X 10.6.0 were compared in the test.
