To tackle upcoming generations of Ultrabooks and NUC that lack space for discrete graphics, yet having to keep up with the demands of higher display resolutions (i.e. proliferation of 3840 x 2160), Intel is designing special variants of its Core "Haswell" processors that feature large integrated graphics cores bolstered by fourth-level eDRAM caches on-package. Pictured below, is one such contraption.

Do you guys think the rMPB 13" will have any chance of having Haswell GT3e?

I mean, it would be awesome to have GT3e as an option for the 13" rMPB, but I honestly dont see how would such a small laptop be able to keep it cool with a 55 TDP.

well the top processor in the existing 13" is the 3ghz/35w dual core i7 (3540QM?), but when Apple did their minor revision shortly after launch they changed the internal layout and it was speculated they did so to prepare for Haswell. If you look at the teardown by ifixit, there is actually some wasted space internally where the SSD is mounted under the trackpad, something Apple - or any laptop designer really, would not normally do. So odds are they have some revision of the board, chassis, and battery layout that would allow for a chip with higher cooling demands.

The additional EDRAM might require extra compiler/driver support, but it could significantly increase the performance of the GPU. Good move from Intel.

At what point will Intel really be competing with mid range discreet graphics? They're already eating into AMD and NV space as it is.

I'd be curious what kind of mobile APU AMD could come up with with a 55w TDP.

Well, thats interesting. However, is important to keep in mind that assuming they do put GT3e in it, how hot will the macbook get compared to current models? How much louder will it have to be too keep it in appropriate temps?

I currently have an ASUS G1S with a 35 watt TDP CPU & a Geforce 8600M GT and trust me, next laptop I get HAS to be cooler than this BBQ machine.

i know that generation of laptop too well ^^
got myself a c2d with tdp of 35 and an X1900M GPU which cooks your hand and eats battery..
i could have changed it for an 8600GT or 8400GS but i went with my HD4650 (mxm modules)

Just use a copper block, an not some "tin"-can fins with a radial whiner!


mmc module anyone? ah good old days with p1 with mmx, 166Mhz on mmc-1 module looks the same :p

There is a reason why Apple uses aluminum chassis. It helps when the case can dissipate heat. I don't expect it to be any louder, but that depends on how much the heat the thing puts out. If it doesn't consume more power it's not going to make more heat and Intel is doing a pretty good job at the efficiency thing on their mainstream platforms for both desktops and mobile devices. The i5 in my air which has a HD 4000 in it can get toasty if I'm compiling something in Macports, but most of the time the CPU doesn't get stressed enough to heat it up all that much. More often than not my air is quiet and pretty cool running.
