Waiting for Broadwell MBP Mega Thread

[xxskorpion88xx]

So here we are:
unleash yours deep speculations

What we have to expect for February refresh?
- 4k2k igzo display

What about June refresh?
- new broadwell onboard (with iGpu 40% faster)
- a new 850m nvidia Maxwell (said 3 times more powerful for watt, so 300% faster see

So what would be yours likely game fps on a 4k resolution on this update spec

Maybe 25 fps Max out gw2 on 4k (850m)
Maybe 20 fps Max out sc2 on 4k (850m)

Considered higher resolution 4k2k then 2800x1800 (40% more) and considered broad well 40% faster we have to expect the same iGPU frame rate on 4k resolution

Will you upgrade your machine?

There won't be a Feb refresh.

This.

Also, every generation there are big expectations but it always isn't as huge as promised. For example, the new NVIDIA GPU's deliver 3 times more performance per watt. But especially Apple would see this as a way to deliver similar performance at 3x less power, not 3x more performance at the same power consumption.

It usually comes down to new generations being slightly faster, having slightly longer battery life. But who knows, we will see. I don't expect it earlier then June anyway, might be even longer due to Broadwell delays.

Get it, but Apple have to choose only of put the nvidia chip inside and if this happen only 850m (300% faster) is the answer to drive correctly a 4k screen

Yes you can put an hypothetical 820m with same performance than now and a three time less power..but what kind of dummy would you be cause in this situation iGpu (40% faster will overcome the dgpu).

Battery optimisation is done by igzo so you can expect 10-11 hours with better performance then now

Some points about next maxwell:

The previously GK108 (630m), GK107 (650m 750m) used in Kepler and GK106 (660m 760m) was:

[Cuda core:texture units:ROPs]

GK108 nm 40 ( old process from Fermi) 96:16:4 switched later in 700 series to:
GK208 nm 28 384:32:8 on 730m 128bit

GK107nm 28384:32:16 (both 650m 750m)128bit

GK106 nm 28 768:64:16 660m 192bit
Reference: http://en.m.wikipedia.org/wiki/GeForce_600_Series http://en.m.wikipedia.org/wiki/GeForce_700_Series

Now some chips Haswell has leaked:

GM106 nm 20 2304:144:24 192-bit

GM108 nm 20?(probably considered the number of core) 1024:64:16 128-bit

For comparison:
780m is 1536:128:32 256bit
770m is 960:80:24 192bit
765 is 768:64:16 128 bit

Source: http://www.hitechreview.com/it-products/pc/rumor-details-nvidia’s-maxwell-chips/44955/

We know that the new 850m should adopt the GM107 nm20 with parameters between the other 2 leaked

Considered that we should expect a 1536:80:16 (hoping 192 Bit ) that is very likely to hit 3 times performance for watt as the slide in upper post says and perform the fps I have hypothesised.
That means performance like 770m maybe slightly better or lower nvidia's architect know how boost it..I sure hope better then 770m for my june refreshed rMBP
