because wouldnt the inclusion of 750m reduce battery life, which is the whole point of haswell?
No--not necessarily. The graphics switching prowess has come a long way with OSx...with Mavericks, even more power saving protocols have been added. If you watch the keynote---it's kinda cool, the example they give. You slide your calendar over the top of the website you're working with (Or browser with dozens of sites open)---it will intelligently shut the power down to the websites while using the calendar and until you re-unite with your browser...and it 'looked' like this was essentially ubiquitous with all apps and software in 10.9. The graphic switching capability is pretty damn good---and my current rMBP is good for 7 hours without power. The 750 is essentially an updated 650 with maybe a 10-15% increase in performance. Essentially the same chip. So if you're using whatever Apple decides to use as the iGPU from Intel (which are MUCH improved over this past year's 4000 series)---say the 5000, or even perhaps the new Iris Pro...it'll be less than often you'll need to utilize the dGPU for normal tasks. Video editing, for some reason the entire Adobe suite
....Flash sites, et al will turn your 7xx card on---but again, with gfxcardstatus you'll be able to control that. Along with Mavericks---I'm anticipating a 10 hour 15" rMBP this time around (in a controlled, 50% brightness environment) which is incredible for a laptop as nice as the rMPB
yeah i get your point, but these days some websites use so many damn animations etc that the dgpu might just think your firing up a game or something and kick in, and tbh you dont normally know when its on unless the fans kick in
Use Click 4 Flash---or any of the dozens of anti-flash measures and plug ins for your browsers. YOU can control this. As well, with the aforementioned gfxcardstatus app, it's free and can easily control when you do/don't want your dGPU fired up (Although it's free---if you have paypal, throw the dude a few bucks, he's maintained a KILLER app for a long time and we shouldn't take it for granted IMO).
I think it probably costs more than you may think. It's not simply the cost of the GPU alone, but hundreds of additional traces on the motherboard. Additional power requirements, which means additional components on the motherboard which require even more traces. These have the tradeoff of also taking up valuable space. Then there's additional cooling requirements and additional complexity in BIOS configurations to ensure proper operation between the IGP and dGPU. With more components, you also have more things that can go wrong, which is another cost as far as Apple is concerned.
As long as the logic board is set up for the dGPU there isn't a whole lot of 'extra' monetary concern. It's EFI on Apple's boards, not BIOS---regardless, if there's an option for the dGPU in certain CTO configs, that work will already have been done in the 'base' config so on the assembly line the extra GPU can be added. I understand and don't disagree with your thought process---but I think Apple has this down now (they're manufacturing). It's my HOPE they maintain the dGPU in the 15" for at least another round or too. While the Iris Pro does well in computation---it lacks in gaming and certain video titling and graphic programs, mainly Adobe's fascination with OpenGL (or do I have that backwards?)---as it is now, Adobe's After Effects works incredibly well on my 15" rMBP. it'll eat all the RAM you give it---but with the GPU offload for some of the work, it STILL makes sense to keep it---at least in the CTO options. IMHO of course---ymmv
If I can buy a whole GK107 chip (desktop 650) from newegg for $90 (with pcb and traces, vram, and including manufacturer and reseller margins) then it doesn't cost apple any more than $70. HP charges $70 to add a 740m to their notebooks. It will take up more space and take additional cooling. Drivers and BIOS will require more work but the actual components will not be that expensive. Most other manufacturers don't really have a hard time with it. A company like apple certainty won't.
Cooling and power. If you run max load on a 15" rmbp it will throttle as it cannot supply enough power. 85w is not enough for OC 650m, quad i7 and retina screen.
Any chances you could share apps or software (other than benchmarking tools) that will throttle the rMBP? Generally curious---we've been using them solely for video editing and effects now over the past year with AK State Troopers, Deadliest Catch and a couple of History channel Docs before we send off to LA (Discovery and Nat Geo) and I have YET to see one of them 'throttle' or slow down---in fact, they easily keep up with my decked out 2009 MacPro with 32GB of RAM (with the exception of After Effects which will utilize every bit of RAM if you let it per frame). I'm not a gamer---other than XPlane, so maybe I'm missing something.
1. The 2012 iMacs had the NVIDIA 650M, so did the rMBPs. Your argument is invalid.
2. Again, same specs in the 2012.
3. Broken record... If the iMacs didn't change in price from 2012 to 2013, why would the rMBPs.
4. This i can agree on. I think they will only do a max of 1GB VRAM.
Note though: avoid using words like "won't" and "never" in your titles unless you are certain. Clearly, research was not done.
True---I agree with your responses. Unfortunately I HOPE they don't go this direction this year...the shared 640/650 of last year's iMac (low end) has now been replaced by the Iris Pro. Granted, I have ZERO experience with Intel's new bad boy iGPU---but the pricing of that Haswell chip with the Iris is almost in parity with last year's Ivy Bridge proc plus the 650m (I think both right around the $375 mark last check?). Hence adding the dGPU will increase the pricing if Apple uses the I/P iGPU in the rMBPs this year (and adds the dGPU as well).
Time will tell.
For those calling the OP stupid....has it ever occurred to you folks aren't as experienced with Apple's releases? Ages of posters on this board? I agree is wasn't worded perfectly with absolutes---BUT come on! Give the dude/dudette a break
---- I think OP---maybe next time instead of making absolute assertions, a post with a question mark would be better and not bring out the divas, and the know it alls. I saw a professional video guy/gal on here the other day arguing about the MacPro being a joke---not for pros, because he's a pro and his system NEEDS---never mind, I need not go on. When I looked at his profile, he joined this board almost three years after me....however, he has almost 5,000 posts in just over two years. I've NEVER met a professional video editor, colorist, finalist, sound dude----no one EVER in Alaska, Seattle, Portland or LA that has THAT kind of time to spend on Macrumors posting this gibberish
Take it for what it is, but I understand the OPs concerns....and to the OP---if it's gaming and a bad ass video card you're after, build your own Windows rig and stack it up! Use an Apple machine to get your 'work' done
Or---maybe, better yet, for the same price as a 'gaming rig' --- you could buy BOTH the new XBox (1?) and PS4 for less cash and have access to most of the AAA titles you'd have on your computer. With Microsoft's transition to incorporating 'Glass' and Sony's expectations to allow iOS devices as controllers could be pretty nifty and a good way to incorporate your Apple purchases with the next gaming consoles.
Not sure what the answer is---but if you're a gamer, you can look elsewhere---Alienware, Razer, ibuypower, cyberpower....the boutique computer industry is active and VERY expensive if you want the monsters. I'm an Apple fan but still subscribe (through Newsstand
) to Maximum PC---and inevitably the review section monthly involves one of the latest, GREATEST Falcon Northwest $12,600 systems with Tri-SLI/CrossFire and 32GB of RAM with SSDs and XTreme Procs with damn near 2,000 watt power supplies that will soon need their own dedicated circuit to power----JUST the tower! I think those days are limited....we'll see what these new consoles are all about.
