First Intel Core M "Broadwell" Benchmarks Surface

Here are some of the first benchmarks of Intel's ambitious Core M processor, a performance-segment dual-core processor with a thermal envelope of just 4.5W, making it ideal for tablets, ultra-portables, and mainstream desktops. At IDF 2014, Intel showed off a 12.5-inch tablet running a Core M 5Y70 chip. An MCM of the CPU and PCH dies, the CPU die features two "Broadwell" 64-bit x86 cores, a large new graphics processor with 24 execution units and 192 stream engines, 4 MB of shared L3 cache, a dual-channel LPDDR3 memory controller, and a PCI-Express 3.0 root complex. The PCH die wires out the platform's various connectivity options.

The 12.5-inch Core M tablet was put through three tests, Cinebench R11.5, SunSpider 1.0.2, and 3DMark Ice Storm Unlimited. With the multi-threaded CPU-intensive Cinebench R11.5, the Core M scores a respectable 17 FPS in the GL bench, with 2.48 pts CPU. That's about 60 percent the performance of a Core i7-870. Significantly higher than anything Atom, Pentium, or AMD E-Series. With SunSpider, the Core M put out a score of 142.8, under Internet Explorer 12 running under Windows 8.1. With 3DMark IceStorm Unlimited, the Core M sprung up a surprise - 50,985 points. That over double that of a Qualcomm Snapdragon 800, and faster than the IGPs AMD E-Series APUs ship with. Color us interested.

If this is true, although i highly doubt it it is along the lines of the i5 4300u+HD4400 while being lower TDP. It might be TDP unlocked a bit higher or something allowing it to boost for longer periods in these sample devices though. Most Haswell Y series suffered from extreme throttling due to SDP/TDP running at 800MHz /350MHz all the time. The surface 3 i3 is one of the devices that doesn't suffer as much as the other variants are U series with larger tdp only the i3 is a Y series one and it still has the active cooling of the more powerful siblings.
And the price will be stellar for a Core M device, i suppose, so the Atom/Pentium will still rule the mainstream as these will cost twice as much, they will kill off the AMD E series maybe.

Is these tests neutral or intel optimised ?

For once, consideration on Window's side for tablets.

What happened with the left side of the display? That orange streak is present in all images. Was the tablet dropped or is that caused by heat from the CPU?

Those are side effects of Intel optimized tests that disable overheating protection.
