continue to evaluate when and where OpenCL will intercept various products"Īnd is there secret Sandy Bridge IGP OpenCL support? Bit-tech got a quote from Intel that Sandy Bridge IGP OpenCL support was inbound sometime this year and if anyone would be motivated to get it done it'd be Apple.Īnd finally, does Apple now support hardware H.264 decoding on ATI or Intel GPUs? Previously, only a few nVidia GPUs were supported in Snow Leopard, such that the Arrandale MacBook Pro actually had to power up the 330M GT to decode H.264 wasting power compared to the perfectly fine Arrandale IGP if Apple just wrote the drivers.

"' will be releasing OpenCL graphics drivers to developers during the course of 2011. Given nVidia's GPGPU push can the HD 6490 still keep up with the 330M GT in OpenCL? How does the HD6750 do? Are the Sandy Bridge MacBook Pro's disproportionately faster than the Arrandale MacBook Pro to indicate that OS X has CPU OpenCL drivers that can take advantage of AVX? Probably not, and this will hopefully come with Lion. First, given Apple was the instigator of OpenCL, it'd be great if you could run some OpenCL benchmarks. I do have some additional questions though.

ltcommanderdata - Thursday, Malink A great review.

The right answer of course is always the last answer you try, so this was only after trying several other ways of calculating the CPU speed and a couple different OS-agnostic benchmarks to try to rule out OS differences.

If you don't go through this process you'll never be able to read the core speeds accurately, which is why there's virtually no Mac software capable of this.įortunately MSR Tools exists, and it has a 32bit extension to allow it to peek at the MSRs.

Under Mac OS X this requires installing an Extension (at least as far as I know) which gets messy.

Linux already does this (/proc/cpu/0/msr), and on Windows it's fairly trivial to load a driver alongside an Admin-level application to do this(CPU-Z, etc). The issue with that is that it requires peeking at the Model-Specific Registers (MSRs), which require Ring 0 access or in other words you need a broker at the driver level to do it. To actually read the instantaneous speed of any given core, you need to peek at the CPU itself and count the cycles - Intel actually has a handy document detailing an algorithm to do this(1). So on the 15" low-end QC model you will always see 2.3GHz. Mac OS X's Sysctl reports the base speed of the processor, regardless whether Turbo Mode is active or not.

Ryan Smith - Friday, Malink Just to add some technical background to this, it's actually quite complex to get a CPU speed reading on modern CPUs.

Hopefully higher resolution notebook displays are somewhere on the horizon. While everyone was speculating about what display the iPad 2 would get, there was very little discussion about how the Mac side of things needs higher resolution to even get close to being able to display 1:1. It's a bit disappointing that Apple didn't take the opportunity to dramatically improve displays on the MBPs this time around. It's a TN and likewise still has the same mediocre vertical viewing angles as virtually every TN. Apple also seems to ship an ICC profile for each specific panel type with LUT curves already, which actually put the display close to where it should be.

It's the same as the previous one, and unsurprisingly the data backs that conclusion up very well. There's shockingly little to say about it that we haven't said before.

We calibrated using the i1D2 and ColorEyes Display Pro same as we did before, then check with the GMB color checker card colors and get Delta E. 15-inch MBP with optional anti-glare screen (front) It's not surprising in the least that Apple is using the same panel there wasn't anything wrong with the old one.ġ3-inch Glossy MBP (back) vs. Before even starting to analyze display quality, I pulled the panel model out of EDID and wasn't surprised to see the same LTN154MT07 Samsung panel in the new 15" MBP as we did in the previous generation. We analyzed the 15" antiglare display on the new MacBook Pro since in all likelihood if you care about display quality you'll opt for the high res or high res antiglare option.
