I think it is going to depend on Broadwell. Apple may wind up delaying the refresh a little to sync up with Broadwell RTM. Either that or if they stay on Haswell you might see a 13 with Iris Pro and the dGPU 15 stepped up to the 850M.

Can you get a dual core with Iris Pro?
 
I'm guessing there that they might do a quad core 13.

Intel doesn't have a quad core SKU that fits in the 13 inch's TDP very well. The clock speed would need to be so low that it would be slower for single core tasks (which are very common) then the dual core that it has now.
 
Looks like people don't realize what Iris Pro is.

Iris and Iris Pro is basically the same GPU. Iris Pro only have eDRAM. Both GPU's have the same amount of cores, same clocks. The difference is high bandwith(arguably...) memory on the GPU die.

What's for Broadwell.

eDRAM will be available in most GPU's, if not in whole lineup. Broadwell GPU's will get 8 cores more - 48 core amount.

Few tinkers around GPU's and we end up with 40% faster GPU than Iris Pro, that is available for whole Intel Processor lineup.

But there is one surprise. Some say(;)), that there will be a 28W version of Quad Core processor with this GPU. 2.0 - 2.2 GHz CPU speeds. I highly doubt there will be that type of Processor in Intel lineup with Broadwell, but Skylake - everything points that it will be true.

So in the end. If HD5800 will be available for whole Intel lineup, and will be significantly slower than Maxwell cards, which it will be in every way. Not putting at least GT860M, looking at the competition - it will be just laughing at customers faces.

But for that, its still few months from now.
 
Do you have a source for the statement about eDRAM? So far all I have heard is it is reserved for the Quad Cores and is implemented as L4 cache.

Technically Haswell iGPUs some in three flavors - HD5000, Iris and Iris Pro. All are 40 cores but the two Iris configurations run at a higher frequency. And between the two Iris boys the Pro means it has the 128MB of L4 eDRAM (a.k.a. Crystalwell). As to who gets it per Intel the criteria seems to be a combination of die size and TDP.

With Broadwell doing a shrink, the Iris class stuff could find its way into lower end packages as the portion of the die occupied by the CPU drops, leaving more space for the eDRAM.
 
I think you will see them bump to the 850m on April 1st (Tuesday.) There are a bunch of sellers in the channel that just put their 15" Retina's on sale for almost 200.00 off of retail. That usually signals a new unit coming, and it would coincide with the six month release window as the last units were released in October.

Pure speculation, but it's wishful thinking on my part. Im in the market for a retina machine and I want Maxwell.
