Futur OpenGL versions will fix this problem and the openCL and OpenGL can run in the same hartware at the same time.
But this article sounds to me a little too happy about Osx Blob locked-in software, so more than a simple benchmark, that, IMHO, it's REALLY bad.
Sentences where Michael state "we remain friendly and interested in other BSD and UNIX operating systems too, including Mac OS X", it's not good, to me.
Of course it's only my opinion.
A little example: you CAN'T do any benchmark with OSX if do not buy his Intel PC hardware, that is a perfectly a clone of a normal PC. It's NOT legal to use Osx on normal PC. It's a stupid RESTRICTION.
IMHO, also only this basic motivation it's enough to ban Osx from any real benchmark. You know: the company behind Osx say that is ILLEGAL to use Osx also if the Hardware it's Exaclty the same, without his ridiculos fanatic snob brandname on it.
This is an absurd restriction to the freedom, contrary to the FOSS that must be punished starting from Linux and FOSS aimed sites like this one.
Of course my 0,2 $
I say about HARDWARE branded that MUST be used to play OSx, otherwise it's ILLEGAL to do also any benchmark. BSD vs GPL flameswar it's not the problem here.
Anyway: IMHO, in the end, i stated here in this thread to Micheal because I think that Apple DO NOT need any free advertising here on Phoronix. They are already so good on hype and marketing, really the best in the world on this, FAR BETTER then their software and hardware manufacturer ability.
If macosX use openGL 3.0 or 3.1 or 3.2 features the Intel IGP will not render this fast becourse the intel driver "can not" render this features.
i think macos himself use openCL features and OpenGL 3.0+ features and the drivers do not support this fully.
Linux and the old macos do not use this features so there no drop down of the speed.
