iris pro or nvidia geforce gt650m

[mekkiatwinyoo]

Apple just release the new retina macbook pro i7-4702MQ 2.20 GHz with intel iris pro(no dedicated graphic) and the old model i7-3630QM 2.40 GHz with nvidia geforce gt650m(1GB)

just wonder, which one is better?

 

thanks.

The GT650M remains 15-20% or so faster than the Iris Pro 5200 (5200 is the top model, don't know which version the rMBP will feature), but I doubt the difference will be noticeable. Most of the graphic upscaling in the rMBP remains a CPU task eitherway.

 

The switch allowed for a thinner chassis and better battery life, not GPU performance gains.

MBP hasn't been built with performance in mind for quite some time now. Nothing new.

 

Also, keep in mind how much more important on-board ram now becomes, as the GT650M was bringing along its own VRAM...IRIS Pro has just 128MB or RAM, utilizing part of the main system memory for complicated stuff...128MB are not enough even for the 1800p screen's default frame buffering.

 

The 4GB versions of rMBP will be pushed hard to keep up with busy viewports.

Having one retina MacbookPro inhouse, knowing how thin it is, hard to image how the revision could make that even thinner :- ) Anyway, the 15" still has GT750m (with 2gb vram) option now, not just Iris, and choice between 8 and 16gb ram so I don't think there is any problem.

i use Sketchup, Vray, Photoshop and maybe 3dsmax (non-gamimg)

CPU or GPU is more important for me.

Iris Pro 5200. sir

so, the old model with GT650M is better, right?

I assumed you were referring to the rMBP 13" or the basic 15" that has just the Iris pro.

 

As Juraj correctly said, the new rMBP 15" still has a model with GT750GT 2GB dedicated GPU - but starts @ $2,500 (pretty decked-out as far as MBPs go, but far from a powerhouse for that price). The basic rMBP 15" starting @ $2,000 has just the iris pro.

 

The CPU ad the number of CPU cores are more important than the GPU as far as rendering potential goes.

 

As far as modelling, and depending on the complexity of the models, the GPU is becoming more important, but neither available options for the rMBP differ enough in performance to make for a definitive answer: both are pretty basic by today's standards = Will do the job equally well for standard / moderate workloads, and equally bad under heavy workloads.

i mean basic 15"rMBP(only Iris pro5200) and the old basic model(with dedicated GT650M).

i'm last year architect student and looking for new laptop for my grad work. The current one is MBP13", just core2duo with nvidia geforce320M, works very well in modeling and also retouching ,except its CPU when rendering.

 

thanks

Any mobily GPU option that would fit in a thin laptop as the rMBP (or even bigger) with current tech, is not that appropriate for GPU accel. progressive renderings...all but the highest grade GTX versions / Radeon GCN mobile cards, despite being "capable" of gpu rendering, are not that fast to be a game changer and drive decisions.

 

If for example the sole reason to go from the "basic" 15" rMBP to the one with the GT750M would be trying out GPU rendering, I would advice against the extra expense. Sure, you don't pay all $500 just for the nvidia chip, but the value you will get out of GPGPU using it is limited to justify it.

 

Things might change as GPGPU becomes more mainstream & nVidia and/or AMD move to smaller lithographies to make cooler running GPUs etc, but for the moment - and given the fact that rMBPs are not aimed to be a "powerhouse" workstation, in my eyes - their user should be happy with good CPU performance, and leave aside GPGPU aspirations, or just look into a bulkier mobile solution that can fit more GPGPU performance.

I am not sure he mentioned GPU rendering at any place :- D It's nonetheless good advice.

 

Maybe it's worth looking into new 15" Dell XPS/Precision M3800 (difference being only GT750m vs Quadro K1100), the top 2 models in each line having 3200x1800px. Not as pretty as Retina with its case, but...damn close enough. 18mm thick.

Bad day @ work, don't ask...

Don't know why, read the above in bold and thought he meant the "new one" would be GPU rendering...then went on with my usual rant...
