Whats the roadmap like after Broadwell? Got a 6-year-old MacBook Pro Id like to replace with a 15" rMBP, but Im not sure if I should skip one more generation.
It depends how important the new CPU architecture will be to you. See my comment at the end of this post.
it will be a revolutionary spec bump =)
all joking aside. I think it is basically speed boost, more battery life(energy efficiency), and significantly faster graphics.
even though it is just a spec bump I am still very excited for broadwell computers.
I am actually super shocked by this! I thought there was no way broadwell would be ready until 2015
I will actually be disappointed if Broadwell doesn't get released by early November. Regardless, Intel has stated that Broadwell's life-cycle will be shorter than most. Intel still expects to release Skylake in 2H 2015.
Broadwell is a die shrink to 14 nm which means improved battery life. There is no new cpu architecture so performance wise it will be comparable to Haswell.
Gpu wise however will see massive improvements, the Iris Pro 2 is said to be 40% more powerful than Iris Pro. That alone is worth Broadwell.
If you want a new cpu architecture then wait for Skylake next year.
I decided a year ago that I would purchase my next Apple laptop when Skylake is released. I might have been swayed by Broadwell because of the advances in power conservation and graphics performance, but Broadwell will be the last of its CPU architecture whereas Skylake is going to become the basis of the CPU architecture for the foreseeable future. Skylake will include Advanced Vector Extensions (AVX) 3.2 512-bit instructions (as opposed to AVX 2.0 currently), SHA (secure hash algorithm) extensions (SHA-1 and SHA-256), MPX (memory protection) extensions, ADX (multi-precision add-carry instruction) extensions, SATA express (10-16Gbps) which is ~2.5 current SATA speeds, PCI Express 4.0 (which may be necessary for NVidia's Maxwell), and DDR4 memory (lower power consumption, more bandwidth, and hopefully also faster unless latency is too high).
Also, Skylake may bring more than just a new CPU architecture. Also due around that time are USB 3.1 (new, smaller connector) and TB 3.0 (twice the bandwidth of TB 2).
Depends on whether by 'launch' he is talking about products with Broadwell CPU's rather than the availability to OEM's to get the CPU for their products. What ever the case maybe it'll be interesting to see what the options will be when it comes to dedicated GPU - will Apple go for AMD/ATI or Nvidia for their iMac and MacBook Pro 15" range.
Hopefully NVidia.
Broadwell is a Tick which means it will have a new GPU architecture (along with Die shrink). Iris Pro 2 is supposed to deliver 30-40% more performance than Iris Pro, which by itself already is an amazing IGP.
This will further eliminate the need for dedicated graphics, which means smaller (thinner) laptops and better battery life.
It is also rumored that Skylake will be the first, true, single-chip SOC from Intel with a fully flexible graphics pipeline (Larrabee).
