Waiting for Haswell MBP Mega Thread

I'm kinda surprised given that I use these sotfware at the same time! you have at least 8G of ram don't you ? But that helps thanks
In my case, 13" is not enough and I can't afford a laptop + desktop so 15" retina seems the best. Am I wrong ?
But do you think all that will run smoothly on a RMBP without dGPU ?
thanks
I'm saying that the eDRAM is useful for completely non-GPU related tasks.
Your example was compiling. During compiling the iGPU probably only needs a few mb of memory for frame buffers. The rest of the 128mb cache can be used by the CPU to store data needed by the compiler.
Tasks that are purely CPU driven will benefit from the extra cache because it isn't just for the iGPU.

With that special ordered haswell chip, with stronger iGPU, we can now conclude that the dGPU is gone.

why? they might just use that one in both and put the dgpu in the 15" just like now.
Hey guys, I need some answer on this I can't find it online. Is the 650m on the 15" alot better than the upcoming iris retina? Because if it is better, I'm going to buy a used 2013 maxed one on CL for 1750. So does anyone know if the dgpu 650m is still good?
About same performance if not a little worse. Your trading a little less power for more battery and a small increase in power. If you play games, then you'll see less of a performance, you didn't really state what your going to use the machine for. Video editing/Photography work will be fine, rendering 3D models might be slower, but we won't know until it's officially announced.
Be careful of scammers too, that price seems unreal :0. (What SSD?)
Apple wouldn't special order a more expensive, more power-consuming version of Iris Pro if they were planning on including a dGPU.
Exactly. If this story is true it's the best evidence so far that there will be no dGPU on the next rMBP.
I know it is a good price. I think I'm going to go through with it, we're meeting at the apple store. It is maxed out, 2.7/16gb/512

Why meeting at the apple store? Does the seller work for apple?
Let Apple inspect Macbook before purchase? Always a good idea, and they don't charge anything.
It is good to know it is free. He might need to request an appointment with the genius bar though. What do they do generally? Check who is the owner and do a hardware test?
Just made the appointment for tomorrow at the genius bar. Yeah I'll just make sure that the computer is legit, all the specs are legit, cause I've seen some people tamper with About This Mac.
but you can't deny higher resolutions demand a larger vram .... the edram can only do so much before it bogged down.
the "slower" dGPU vRAM still has lots of advantage in 2880 res.
Each pixel is a byte. So 4 million pixels is 4 megabytes. So you can have 32 cyclic framebuffers for the display.
Just for curiosity, what are those advantages?
video games rendering is one of them ...
photoshop rendering of high res images also consumes lots of VRAM although not into 2GB range ...
take an example, two photos with same resolution ... but different in size ?
these textures not always directly correlate 1 pixel to a byte ... sometimes it could be more or less ...
Actually, one pixel (in color) is 3 bytes.
And there's much, much more to it than just to buffer pixels. See dedicated graphics cards, they have 2GB+. Why would they use 2GB when they only need 12MB for the pixel buffer (according to your statement)?
If I don't wait for the new Haswell macbooks because I don't own a laptop and I'm heading off to college on the first of September, which of the Pros would be the best option? There are the 13" $1500 versions, one a retina, the other slightly upgraded. Is one better than the other? Is the retina display worth it? What about a refurbished 15"? Not portable? I went through all other laptop brands (Asus, HP, Lenovo, Dell, Acer, ...) but couldn't find a similarly portable 13" laptop with good quality parts/hardware. I want to wait for the Macbook refresh in a few months, but I don't think I can go through school the first months without a computer.
Also, consider the cost of the new MBP with Haswell. You would be paying $300-500 more for the new Macbook Pros with Haswell when they are released in fall. Right now, you can buy a MBP from BestBuy for $1175. So yes, if you wait, you would be purchasing a new improved machine, but it would also come at a higher price than the current line of MBPs on sale.

I'm staring at the final checkout page. A dangerous place to be, heheh. This 13" rMBP with the upgraded "2.9GHz Dual-core Intel Core i7, Turbo Boost up to 3.6GHz" will serve me well right? With education pricing, it's $79 more than the base price 13" rMBP on the main store.
I wouldn't pay $200 extra for those 400MHz. You won't even notice unless you're doing number crunching or video transcoding.
Upgrade the SSD instead.
Indeed 3 bytes are needed for each RGB pixel. You would just need to alternate between 2 framebuffers (24M) for refreshing the screen.
My understanding is that the dGPU has a more complex instructions set optimized for 3D rendering. The extra vram would be used for intermediary buffers needed when performing graphics calculations.
For tasks not related to 3D rendering, I don't think the 2GB are needed to handle the retina display...
If there's no dGPU and no IGZO after all the waiting, some people here will be seriously pissed
No one will be pissed
Because we all know there will be no dGPU in Haswell rMBP - Status
