Can Macbook air 13'' i5 handle 3D rendering? `I'm an University student studying Interior design and will be using apps like Live Interior HD, Maya, and windows via bootcamp.
The Airs in general are an absolutely terrible choice for what you are doing, and I'm going to provide a reasonable explanation.
3d rendering requires a certain amount of ram to render. Unless you want to dice it up into sections, you can hit a wall on ram with 4GB. Note that it requires real ram, meaning memory paging to an SSD will not solve your problems. The cpu takes much longer than some of the others. I mean exponentially longer. The i5 vs. i7 thing is handled terribly by Intel because their features aren't consistent across all lines. In the desktop cpus, only i7s have hyperthreading enabled. With cpus designed for laptops (this includes the mac mini) hyperthreading is also enabled on the i5 variants. Really there isn't such a big difference between the two there.
Next up is the gpu. I don't know what software you're working with, but the integrated graphics options have a lot of issues. They're both slower and buggier with 3d. It's just not fun to use if you're going to be working on models with any real amount of detailing. Last having a really high quality display will help you spot details more efficiently.
The Air already has weak graphics, and hooking it up to an external display would just make them lag even more. The display the Air uses is really sub par for this kind of work. It's not Apple's fault. They designed the Air to be slim and light. It comes with compromises that don't significantly affect the majority of its users, but its target market is not people who work in 3d modeling or rendering.
You need to understand in an Air you're paying for a compact machine with an expensive SSD (it has to use high density memory due to size constraints). It's just not designed for raw computing power, but we've gotten to a point where many users can accept compromises in those areas without feeling throttled in their workflow.
i'm not really agreeing with your explanation while completely in accord with the verdict!
In my past experience (pre mac that is) the crucial hardware for rendering (just rendering, i.e. vray, maxwell render ..) is cpu.
Gpu comes in only if your level is high enough both software and hardware wise.
Ram come to play when modeling in 3d but not rendering, in my opinion.
And no airs or better any low voltage cpu (even the i7 )can't be considered good for rendering, maybe they can be used for low fi rendering or casual rendering.
Aris can also reach very easily reach the 100 celsius degree mark. So it can overheats with flash ony let alone with rendering.
I was making some assumptions there due to a lack of full information. I don't know if the OP is rendering for print resolutions or not, but that can consume quite a lot of ram. I also don't know if he still works on the computer while the render is being processed. I was assuming he's doing some modeling, and that can be somewhat intense on the gpu. Maxwell only uses the gpu for previews if I recall correctly, and Vray RT has some limitations, so yeah the actual rendering portion is basically cpu bound, but if he's doing any modeling, panning over a large number of polygons won't be fun with integrated graphics, and they can have more bugs.
I didn't know the temperatures went up that high. I'd definitely want it to be at a somewhat conservative temperature for a long render. It would suck to have the thing shut down due to overheating on a long render.
Anyway Maxwell would be absolutely painful on a macbook air, but do many people really use that one? The look is really nice but it seems like it would compromise your workflow just by how long it takes, especially if you need different iterations.

Thank you for participating.
Yes, I'll be modeling as well.
I'll be graduating in September 2012 and after that I'll be working. So I guess long term Macbook Pro 15'' Late 2011 Base model will be the best option.
But will the modelling and rendering be smooth if I don't install a SSD? Very tight budget so..
An SSD is virtually meaningless there (enough ram > cpu > SSD in terms of performance gains). If you're picking up a lot of performance from an SSD during cpu intensive processes, it means you're light on ram. Basically disk paging is faster with an SSD, but ram is often a cheaper option. Just going to 8GB which you could do yourself for around $50 would benefit you greatly, even if it's not all in constant use. No one likes it when their computer becomes unresponsive due to page outs, and that will help.
If you can afford it, a quad core model isn't a bad idea, but Apple charges quite a lot for them. The macbook pros should probably be all quad cores, but they might run a little hot for the 13" or something. I'm slightly surprised you're using a mac for this stuff. Most of the modeling/rendering stuff tends to be written primarily for Windows, and to a lesser degree Linux. OSX ports have been a more recent thing, like AutoCad returned to the mac a while ago.
The short answer is you don't want an Intel HD3000 for 3d rendering, period. Frankly, you don't really want a GeForce or Radeon card, either--but since Apple refuses to put Quadro/FireGL chips in their Macbook "Pro" machines...it's the best you'll get.
If you can live with a PC running Win7 or *NIX, you'll be much happier with a pro-grade machine like an HP Elitebook/Dell Precision/Lenovo ThinkPad W-series. Gaming graphics cards are something less than ideal for pro 3D work.
(This isn't a Mac vs PC thing...really. Apple simply doesn't put the right hardware for the job in any of their laptops).
It's a LAPTOP not a Professional Super Computer!
The 2011 15" MacBook Pro is amazing for the size and weight that it is.
GiulioUngaretti was correct. The gpu has very little to do with rendering. Some software uses it for faster previews, and they all describe how they use it on their respective sites.
Respectfully, I disagree. If you have a high poly model that you are constructing, a more powerful GPU is going to allow you to navigate the model more smoothly. You could say that's only "previewing" the model and not actually "rendering" it, and that would be okay. But as a percentage, how much time is spend building/previewing the model vs how much time actually rendering it out? I know for the models I do (which aren't very complex), I spend about 40 hours building the model and about 1-2 hours rendering it out. That means that only 5% of my time is actually spent rendering, vs 95% previewing.
Also, unless you're on a really tight deadline, you could always set up renders to be done overnight. (Or grab a cheap QC windows box with a lot of RAM as your rendering machine).
FWIW: My work machine is a C2D, 4GB RAM & Quadro FX 4600 768MB.
Thanks
That's what I want - smooth navigation. If I'm designing a room, I want it to rotate/ navigate smoothly without any buffering or sticking or hanging.
I've heard that by increasing the ram to 8GB, the integrated graphics increases to 512MB, so do you think will it(13''MBP) be enough to navigate smoothly or should I go for 15'' base model ?
I'm studying Industrial Design in school, and the 13" MBA with i5 is handling all 3D Modeling/Rendering needs very well for me.
I'm not exactly sure what kind of softwares Interior Designers use for their modeling/rendering, but my MBA can handle softwares like Rhino, SolidWorks, and Keyshot without any issues.
the 15" Pro will no doubt be faster, but the 13" Air is also capable of doing these things based on my experience.

Thank you very much for your input! I wanted an answer from someone who owns MBA and does 3D Modelling. so Thanks
are you able to navigate through the model smoothly or is there some lag while dragging or rotating in solidworks? I use Sketchup as well. Do you think it'll run fine on it?
and is it your only computer or you have an iMac etc apart from it?
Look, as much as my love my Apple computers, in this case, since you've a limited budget, an Apple computer is not the right tool for the job.
You have pretty demanding requirements and I cannot see an MBA being able to satisfy them. The top end 15" MBP would be far more appropriate but you can get a Lenovo W series with a graphics card (quaddro) especially designed for the tasks that you're planning to do and with the same CPU for much less than a 15" MBP.
You seem bent on getting an Apple computer regardless, but I would caution you.
Edit: lApple has a 14 day return policy. Get the MBA and use it. That's the best advice any one here can give you since you'll then be able to assess whether it meets your needs or not.
