Haswell, Iris, Thunderbolt 2.0, PCIe flash storage, 1080p camera, 9hrs of battery life, 802.11ac, thinner, lighter, Mavericks, and price reduced by $200? This is a great day for anyone interested in the 13in rMBP.
At least they brought the prices down....
So who's getting the 13" and 15" and why? I'm seriously debating whether or not to wait for igzo and broadwell...
Guys, anyone know how much VRAM the 15" MBP's Intel's Iris Pro 5200 has?
I've checked Apple's website but it doesn't mention anything at all.
Thanks

I'm definitely getting one of the 13" rMBPI'm just not sure if 256 GB SSD is enough for me and the price difference of $300 for 512 GB seems quite a lot. Or is it just me? And no possibility to upgrade in the future - so it's a tough choice...
on keynote, he said 13" has haswell 4th gen processor. for 15" he said crystal well chip. Is there a difference? what is the difference? I can't find anything on google about this. Thanks.
There are four versions of the integrated GPU: GT1, GT2, GT3 and GT3e, where GT3 version has 40 execution units (EUs). Haswell's predecessor, Ivy Bridge, has a maximum of 16 EUs. GT3e version with 40 EUs and on-package 128 MB of embedded DRAM (eDRAM), called Crystal Well, is available only in mobile H-SKUs and desktop (BGA-only) R-SKUs. Effectively, this eDRAM is a Level 4 cache shared dynamically between the on-die GPU and CPU, and serving as a victim cache to the CPU's L3 cache
As weve been talking about for a while now, the highest end Haswell graphics configuration includes 128MB of eDRAM on-package. The eDRAM itself is a custom design by Intel and its built on a variant of Intels P1271 22nm SoC process (not P1270, the CPU process). Intel needed a set of low leakage 22nm transistors rather than the ability to drive very high frequencies which is why its using the mobile SoC 22nm process variant here.
Despite its name, the eDRAM silicon is actually separate from the main microprocessor die - its simply housed on the same package. Intels reasoning here is obvious. By making Crystalwell (the codename for the eDRAM silicon) a discrete die, its easier to respond to changes in demand. If Crystalwell demand is lower than expected, Intel still has a lot of quad-core GT3 Haswell die that it can sell and vice versa.
Unlike previous eDRAM implementations in game consoles, Crystalwell is true 4th level cache in the memory hierarchy. It acts as a victim buffer to the L3 cache, meaning anything evicted from L3 cache immediately goes into the L4 cache. Both CPU and GPU requests are cached. The cache can dynamically allocate its partitioning between CPU and GPU use. If you dont use the GPU at all (e.g. discrete GPU installed), Crystalwell will still work on caching CPU requests. Thats right, Haswell CPUs equipped with Crystalwell effectively have a 128MB L4 cache.
I need to take a desition... but can't...
Opc 1:
Refurbished 15.4-inch MacBook Pro 2.7GHz Quad-core Intel i7 16GB RAM - 256SSD with Retina Display u$s 2169
Opc 2:
New! 15.4-inch 15-inch: 2.0GHz 16GB RAM - 256GB PCIe-based flash with Retina display U$s 2199
What do you think?? HELP!
I personally went for 1TB. The think the extra money spent should be easy to recoup in the future upon resale (should I choose to upgrade again latter).
Get the retina display. Your eyes will thanks you later.
-- misread that. they are both retina. I personally would go with the new one. I doubt you'll notice the 0.7ghz.
I am planning to get one of the new macs, but the problem is do I get the 15" cheaper version or the 15" with 2GB Graphics???
I am not a gamer, however, I do alot of photoshop and movie editing. The more expensive 15" is a bit over the top for me with the pricing, so I thought that if I do get the cheaper one, I would update it to 16GB of RAM. What are your recomendations?? Which option is better for me???![]()
