First Intel 14nm Broadwell Core M Benchmarks Unveiled

MojoKid writes Intel Execs out at IDF this week in San Francisco have let slip some actual benchmark run results on Intel's just-released Broadwell Core M processor platform. Intel has gone into detail on Broadwell's architecture and features previously and has discussed power consumption and performance expectations. However, now we finally have some cold, hard numbers, rather than just percentage comparisons versus previous generation Intel platforms. Intel was demonstrating a 12.5-inch Broadwell-based, Core M 5Y70-powered Windows tablet live and the benchmark runs look promising, with 3DMark scores in the 50K range. The Cinebench results shown place the CPU on par with full-fledged Core i5 notebook variants in the 15 Watt power envelope, but powered by the new 4.5 Watt Broadwell Y Core M processor that will be employed mostly in 2-in-1 hybrid devices and high end tablets.

There is a point where you start to get very small marginal increases in battery life for large increases in power efficiency.

      These chips are an order of magnitude faster than the fastest tablet ARM chips. If you look at performance/watt the intel chips are much more efficient too.

      The advantage of the arm chips remains that can operate in a lower power envelope. Their drawback is they cant approach the speed of the intel chips. (Intel chips are more expensive though)

      Intel is the best chip maker in the world. Their fabrication tech is a full 2 generations ahead of their nearest competitors. When intel decides to pull their head out of their own ass and focus on something serious they do quite well.

      In my oppionon Intel's problems are entirely management driven. When they finally decided to ditch the netburst arch and develop the core/core2 they left AMD in the dust and have to this day. They've taken a long time to take mobile seriously. If they do, they will leave ARM in the dust as well.

      If you're an opensource advocate I would welcome intel with wide open arms. Your typical ARM SoC is a fucking nightmare labyrinth of never-updated closed source drivers, zero documentation and one-off hackish implementations with no standards.

      The story I got from my friends who work there (circa 1 year ago) is that they are scared to death that the tablet/phone markets escaped them. Desktop replacements have slowed, and they missed the boat on phones/tablets. They suck at being lean and mean, so they have almost always just outgrown their screw-ups. Chips like this make it clear that they really have made strides to close the gaps where they could.

      It still stands that they have to push out an entrenched ARM competitor, and they appear to be trying to do so by targetting the 2 in 1 side rather than tablets directly.

      Intel has been very good at making efficient CPUs, but not systems. If you want to make a <5W SoC there's a whole lot of other skills you need than a 15-150W processor and Intel has clearly been on a steep learning curve there. Also they've been geared a lot towards efficient computing, while the chips that go into phones and tablets are far more about being efficient at idle and light load. Intel has been learning many new tricks to only power up what they need in the lowest possible power state for a short a time as possible. The improvements for a processor running at 100% load 24x7 has been far more moderate.
