    People holding out hope that Windows on ARM will exist after Windows Blue

    are just stroking themselves. LOL. There is NO WAY Windows on ARM will be around. Backward X86 compatibility is the killer.

    • Then Microsoft will fail in the mobile market. Surface Pro is too heavy, too hot, and too consuming.

      I am making the logical assumption that Microsoft doesn't want to fail in the mobile market, and will still maintain ARM support.

        One-chip Haswell ULT aims for 8- to 10-hour battery life

        Tablets and Ultrabook friendly SoC

        We managed to get a few more details about Intel’s one-chip Haswell platform that people internally also call Haswell ULT. ULT means that the part operates on ultra-low voltage and is quite self-explanatory. The main difference between one-chip and two-chip Haswell mobile CPUs is that the one chip part has the Lynx point LP PCH chipset inside of the CPU package. One can view this chip as a SoC (System on chip) and it will come in BGA package.

        Intel also referred to this chip as part of its Y-processor line of products, with a 11.5W maximum TDP and scenario design power of 7.5W. This is quite exceptional considering that this is the TDP of the complete SoC. In contrast, the Ivy Bridge Y-processor line had a 13W TDP (7W SDP), and that was only the CPU.

        Determining the TDP of Exynos 5 Dual

        Now this is a fairy contrived scenario, but it's necessary to understand the behavior of the Exynos 5250. The SoC is allowed to reach 8W, making that its max TDP by conventional definitions, but seems to strive for around 4W as its typical power under load. Why are these two numbers important? With Haswell, Intel has demonstrated interest (and ability) to deliver a part with an 8W TDP. In practice, Intel would need to deliver about half that to really fit into a device like the Nexus 10 but all of the sudden it seems a lot more feasible. Samsung hits 4W by throttling its CPU cores when both the CPU and GPU subsystems are being taxed, I wonder what an 8W Haswell would look like in a similar situation...
