Intel Discloses Core M Broadwell Speeds, Feeds and Performance Expectations 60
MojoKid writes: Intel's next-generation Broadwell Y (now known as the Core M processor) is set to ship on schedule for the end of the year. The company, occasionally flagged with criticism of its delays on the chip and with its IDF show rampingup next week, is sharing more detail on the upcoming speeds, feeds, features and performance characteristics of its new 14nm mobile platform. Intel's Broadwell-Y lineup initially consists of three chips with apparently very little difference, except for clock speed. Base idle frequencies tip-toe along at 800MHz to 1.1GHz, with max turbo frequencies up to 2.6GHz for the dual-core chips that Intel is announcing today. All parts are able to hit a very low 4.5 Watt TDP (Thermal Design Power) power envelope. Intel is also claiming clock-for-clock gains at the CPU level but also a 40 percent gain in graphics performance, versus the previous generation low power Haswell architecture. Larger, premium tablets and 2-in-1 devices are expect to start shipping at a trickle in Q4, with a larger volume ramp in Q1.

You don't get comfortable quick... Over the last 10 years the only time I've decided to upgrade a mobo videocard was during a drunken weekend when for some reason I felt ashamed of having an item with a 4.5 score on the Windows Experience Index utility - I went out and bought a pair of high-end Radeon (with the SLI thing). About $600 to get a 9.1 score.

Well I also believe that SLI is a Nvidia technology, I just checked and on ATI cards the equivalent was crossfire. I can't tell for sure which one it was, but this is more evidence to the fact that I've been using onboard vga adapters for quite a long time :-)

It looks like Intel is making the GPU larger and more powerful with each iteration.
Well, these chips are primarily for tablets. Fanless tablets. Pretty much the exact opposite of where you'd like to do any serious computing. The CPU is these things mostly exists to support it as a presentation device. I think many people haven't realized how much Intel has moved into the GPU space though, simply because they still think of it as a CPU with integrated graphics. True, they're not competing in the high end discrete graphics cards but they're eating away at the dGPU chips that used to be in all laptops, now you just find them at the very high end. If they took their EUs, put them on a separate chip and multiplied it up to a 250W power budget I wonder how far up the totem pole they'd reach.

I don't think you realize the performance level of a latest Intel dual core CPU that scales between 1.0 and 2.6GHz. It's fucking good enough. Better than Pentium 4, Atom and slightly old ARM, which is what people often are actually using. If you're doing video encoding or RAW photo importing and don't give a fuck whether it takes 5 or 15 minutes, one or two hours.. Good enough, can use AVX/AVX2 for that and you can still use the computer while background processing is occuring anyway.

The gimmick with these chips is that they will enable "fanless" (maximum temperature of 41C, not much more than body temperature) and thin form factors with plenty of performance (hoping for a Surface revival or that people will cool on tablets and get 2-in-1s for "productivity"). TDP nearing that of Atom, but with much better performance. Much of that might be from this huge gulf between the base and turbo frequencies. I can't recall seeing such a large difference between them before. That also means that

Well, if you look at their power distribution graphics it's now primarily screen, then CPU and then SoC. Even though Intel is improving the last two it seems that to take anything to the "next level" we need more power efficient screens.

Why just tablets? This sounds like a full powered, full featured processor for smart phones and a serious attack against AMD's mobile market share.
Their marketing promises are largely useless (productivity up to 19% better? 3-D graphics up to 47% better? What does that even mean?) but with graphics, wireless, and fast processing in a low power chip they're already there.

That sounds low, here's a test [notebookcheck.net] of the iPhone 5 and at maximum power draw they killed a 6000 mWh [leancrew.com] battery in two hours meaning a power draw of ~3W. Of course that includes the screen and the whole SoC, but if you can put a 5W processor in a tablet I'm thinking 1W in a smartphone seems reasonable. P.S. My Google-fu says that <10 mW is only if the CPU is in suspend/standby mode, basically it's off and waiting for the network or user input to wake it up again. Idle but active draw seems to be more like 30-50

Most recent operating systems will take care of saving power when the machine is idle, it won't make a noticeable difference what cpu you pick. Look instead at storage: SSD use between 1/3 or 1/4 of the power used by spinners.
Also if you look at energy efficiency buy one of those smart powerbars that will turn off power in groups (e.g. switching off the speakers when the tv is powered off). Something like a LCG5. This will have a much higher impact on your power bill than cherry-picking computer components.

Those CPU power states the operating system uses are provided by the CPU, and the supporting chipset and power circuitry on the motherboard do determine the power use at idle too. E.g. Haswell CPU have significantly lower idle power use than Ivy Bridge/Sandy Bridge, and introduce another idle power state on top of that.
Good hardware reviews sites do tell you about that. Likewise if you use a dedicated graphics card : e.g. Radeon 4870 wastes a shit ton of power even when you use it as a dummy 2D buffer (idli
