Intel Broadwell-E, Apollo Lake, and Kaby Lake Details Emerge In Leaked Roadmap

bigwophh writes: In Q4 2016, Intel will release a follow up to its Skylake processors named Kaby Lake, which will mark yet another 14nm release that's a bit odd, for a couple of reasons. The big one is the fact that this chip may not have appeared had Intel's schedule kept on track. Originally, Cannonlake was set to succeed Skylake, but Cannonlake will instead launch in 2017. That makes Kaby Lake neither a tick nor tock in Intel's release cadence. When released, Kaby Lake will add native USB 3.1 and HDCP 2.2 support. It's uncertain whether these chips will fit into current Z170-based motherboards, but considering the fact that there's also a brand-new chipset on the way, we're not too confident of it. However, the so-called Intel 200 series chipsets will be backwards-compatible with Skylake. It also appears that Intel will be releasing Apollo Lake as early as the late spring, which will replace Braswell, the lowest-powered chips Intel's lineup destined for smartphones.

We're almost at the end with current tech

14nm for these chips puts us close to the end of currently deployed technologies for transistor densities.

"The path beyond 14nm is treacherous, and by no means a sure thing, but with roadmaps from Intel and Applied Materials both hinting that 5nm is being research, we remain hopeful. Perhaps the better question to ask, though, is whether itâ(TM)s worth scaling to such tiny geometries. With each step down, the process becomes ever more complex, and thus more expensive and more likely to be plagued by low yields. There may be better gains to be had from moving sideways, to materials and architectures that can operate at faster frequencies and with more parallelism, rather than brute-forcing the continuation of Mooreâ(TM)s law."

We've been moving sideways for 10 years. In the 20 years before that, clock speeds were doubling every year or two. For the last 10, we've moved from a norm of single cores to a norm of 4 (or 2 + "Hyperthreads"), rotating hard drives to SSD, and specialized architectures to support HD video, but clock speed has been basically stagnant while the processors are getting fatter, more parallel, and not just in core count.

10 years ago, Intel was hinting at a massively parallel future (80 core processor rumored in development at the time), they've been slow to deliver on that in terms of core count, but are making progress on other fronts - especially helping single cores perform faster without a faster clock.

Re:3+GHz speeds, extra cores, more lanes.

That is unlikely to happen. Parallelizing most things is orders of magnitude more complex than writing them single-task, and for quite a few things it is either impossible or gives poor results.
