I'd wish, it was a whopping 33 points and took around 20 minutes to complete. Idle SOC consumption is 2.9W according to ThrottleStop, IB isn't able to do much at all with just 2.5W extra for its cores. Seems like a lot of improvements went into that with Haswell and Broadwell.

That seems about right. Broadwell is 1.75X faster than Surface Pro 3, which is also about the speed of 2.6GHz Core M, so Broadwell turbos to 4.55GHz / 1.05 IPC = 4.33GHz.

If Intel were marketing their Core M processors like Qualcomm does, they could say it is a 4.3GHz CPU 😀.

Edit: I only read the first post, the IE thing makes more sense than some secret ultra high turbo.

The benchmark can't see this either. It measures the "process-time"
when the processor is active and running at maximum frequency.
The benchmark doesn't measure the time when the processor is idle
and cooling down. Therefor you get a benchmark result as if the
processor is running always at maximum burst frequency.

I pity the benchmark that uses core clock cycles as a method of time keeping.

You can measure unhalted and halted clocks with the performance counters and apply them accordingly.

IMO it would have been better if they were both compared at their defaults to emphasize the power savings of the newer processor.

For instance a car manufacturer making an economical car with 1BHP engine would possibly show how good mileage is, not take a Ferrari and set it to also run at 1BHP so it runs like a dog then possibly even say the economical car runs up to 50% faster than a "comparable" Ferrari.

Advertise it for what it is, an excellent low powered CPU with great battery life. Wonder how many people are going to miss the fine print and expect it to run 50% faster than the i5-4302Y it was compared to.

Definitely agree. Piroko's evidence shows at least one example of the ridiculousness of limiting TDP on a chip not designed for that limited TDP.
 
My humble g3258 does 124.5 in firefox and 63.1 in IE 11. Beat that 😛
But yeah I'm wondering if one of those tests was done in FF vs IE, cuz IE is twice as fast on this test. There is no conspiracy, IE is just much better built for JS, and not in benchmark only, My friend had a google book with 500 pages and like 100's of comments on each page, and it loaded like 100x faster on IE than on Chrome/FF

some perspective:
Note that these are the scores from a high-end 6W TDP Core M 5Y70. The 4.5W TDP Core M SoCs won’t perform this well and in a product with a less-than-perfect thermal design there could be heat issues that prevent Turbo Boost reaching these high levels.
GPU performance needs to be further tested and long-term gaming could impact Turbo Boost capability.
This is the best you’ll see from Core M at 2.8Ghz but it’s important to remember that this is best-of-Core M right now. I’m going to be pushing to get the new Lenovo Helix 2 in for testing so at that point we’ll get our first real-product results.

All Core M chips have 4.5W TDP. 25% above TDP (6W) is PL2 Turbo. Lots of denial in this thread. 🙂

The PL3 boost state allows the most amount of power that won't damage the system's battery, used for very short spikes as needed - the kind of time spans that are measured in milliseconds. PL2 is the standard burst limit, and PL1 represents the long-term system limit of sustainable power delivery. If necessary, duty cycle throttling can turn blocks of the processor on or off to minimize power usage and heat generation.

Its unreal every time Intel does something good the tin foil hats come out. Even if performance was closer to i3 than i5 it would be an amazing chip
 
that does not work ... sorry ...
(the Surface 3 Pro used Chrome, and I used IE for Core M)

The tiny "4.5W" Core M seemingly humiliates the previous record holders,
including the Core i7 4790 Devil's Canyon running at a burst speed of 4.4GHz.

I guess we will see many claim that Intel's new 14nm process is now 20
times more power efficient as Intel's 22nm process or similar wild claims.
(Even though Intel itself never made such outrageous claims of course)


Those who know how Intel's Burst Mode work will understand how you
can produce these kind of miraculous benchmark result. They will wonder
instead if the new F-stepping can now officially be boosted to 4+GHz
for very short periods of time.

Here's explained how it works:

The figure at the bottom right with the three blue spikes explains it all.
The blue spikes mean that the processor is running at maximum frequency
while during the intervals the processor is basically halted.

Say with a single active core Broadwell at 14nm, running a 4+GHz requires
~18 Watt (would be very good!).

A power dissipation of 4.5 Watt would mean that the processor is bursting
at maximum frequency during 25% of the time and idle during 75% of the
time to cool down.

You can't measure this at the outside of the package because the on-
package voltage regulators and capacitors take care of the large power
and current spikes. From the outside you only see a processor using
4.5 Watt.

The benchmark can't see this either. It measures the "process-time"
when the processor is active and running at maximum frequency.
The benchmark doesn't measure the time when the processor is idle
and cooling down. Therefor you get a benchmark result as if the
processor is running always at maximum burst frequency.

That is a lot of Potatoes into your brownies, the solution of this mystery is a lot simpler ... the number used in those chart use different Web Browser, Surface 3 pro ran with Chrome, while I used Internet Explorer ... IE is a lot faster at Sunspider than Chrome. IE is as well optimized as Safari for Sunspider, it makes it the right reference for this comparison.
A Surface pro 3 using IE gets around 110 to 130 depending of the models, The 4Ghz part is a nice piece of Science fiction, I wish I could get this in 6W (what the demo setting was), but I think this will be for an other day.

Then why do a deceitful benchmark where almost every other setup is running anything besides IE, and the Core M is using this web browser?

The same applies when people cheer on Apples performance. Different browser as well.
 
so net net the conclusion is CORE M is still ridiculously fast and a marvel of engineering. haters gonna hate

Everybody who bought haswell - E is gonna feel like they just bought a westmere i7 if intel's performance figures are right. Worse, really.


I say this with my haswell laptop to my right.
