Thoughts? Are they going to stick with the GT650M 1GB, or update it? I use my 15" for a lot of gaming, and would consider trading it for a new one if the graphics card is going to receive a significant bump.

750 or 60M, a 5-25% faster rebrand and overclock of the 600 series.

It's another Kepler-architecture card, and probably the 750M. Wait for Maxwell if you want any kind of meaningful increase.

Does anyone know what is common for year over year graphics performance increases?
I think if they use the 750M they will up the Vram to 2GB. 1gb is pretty low for such a high resolution display.
Keeping fingers crossed for the 760M though.

2GB is most likely not going to happen. Maybe as a BTO option.

I'd like to see the low end model have just the iris pro and be priced at $1799....but I doubt we'll get that.

1GB of Vram has been available since the early 2011 mbp
2 years seems like it would be enough time to offer 2gb as an option but who knows.
Seeing as the 650 to 750 is not a big jump and the retina screen could use a bit more power I wouldn't be surprised if they added 2gb as an option... but then again I wouldn't be surprised if they just put a 750 and called it a day.

a 750 seems like it would offer little to no additional performance over the current 650 in the rmbp seeing as the 750 is just an overclocked 650 and the 650 in rmbp is already overclocked.

A 750m performs above the 660m. With GDDR5 memory it is comparable to a 670m.

1 GB is very low in 2013. Apple should bump it to 2 gb atleast.

The GT 650m in the retina mbp is already overclocked to 900mhz and already has GDDR5 vram. I believe it also outperforms the stock gtx 660m. unless there are other changes between the 650 and 750 I doubt they'll overclock the same chip even further and call it a day. An under clocked 760 may be more likely if graphics performance is a priority for apple.

Nope.

With boost

rmbp 650m 900 core 1250 memory

660m 950 core 1250 memory

750m 967 core 1250 memory + boost (core speed usually of 1050+)

Isn't the GT650M a lesser GPU than the previously used 6970m? I don't understand why they use the 650 across the entire range of mbp's that use GPU's. :confused:

spec comparison

You're talking about Apple here. The low end 15" early 2011 and the 2011 mini both shipped with 256 in 2011, the mini into Q3 2012. They aren't very generous on that one.

If graphics is a priority for you and the new rMBP only gets a GT 750M then you might as well save money get a refurbished ivy bridge rMBP and OC through bootcamp.

so far the way all the 700 series cards have been going they seem to be an upgrade from the previous 600 series. Like the 770 is in fact a higher clocked 680. the 760 will probably be a higher clocked with more cuda engines activated 670 and so on. So it will be faster =) hopefully.

that analyst kuo believes they might remove the dGPU entirely and go integrated graphics.


people will cry

and people will tell them they shouldnt have bought macs for gaming.



at least thats what happened with MBP13 when it went from dGPU to integrated.

That is different. Intel forced Apple to have 4 chips whereas previously 2 would work. Apple needed to save space so the dGPU got cut. That is why the previous gen 320M (I believe) was stronger than Intel's GMA.

The difference here is that an intel cpu with iris pro (intel 5200) would have a:
1. slower CPU than the previous rmbp 15
2. slower GPU than the previous rmbp 15
3. better power profile, but only when taxing the GPU

In your example, it got a faster CPU but slower GPU.

If apple uses the Iris Pro, it will be a slower computer all around compared to the PREVIOUS GEN rmbp...which is why I think it is highly unlikely. Instead, I think it'll go in a 13" rmbp.

Except that running solely on integrated graphics is an ideal situation for Apple. With the Iris Pro 5200 graphics managing to match the capability of the 650M (almost), it makes more sense for Apple to not use the 700M series of dGPUs. Overall, the rMBP would run much cooler if it only had integrated graphics.

Can you link to that benchmark? It was my understanding that Iris Pro was only 50%-60% of the performance of the 650M. It would be quite a downgrade, I heard, but if you found otherwise...
