No doubt the Haswell has an impact but so does more efficient LEDS in the display, better display tech, more efficient memory, firmware, etc.

The benchmark shows what it was trying to show, the contributuon of the processor on power draw. An attempt to isolate the processor makes complete sense. Battery life of the various phones would be meaningless as there are so many other parts of the phone that play into this. This is not a phone benchmark per se but a processor benchmark (plus likely power conversion and memory subsystem).

Ah, now you say, 'if time is equal'. That is the one, solitary case, where the statement is true. But why would time be equal? Especially on different architectures, with different instruction sets and different processes. Also compilers and a whole lot other issues. Under many circumstances the chip that dissipates the most power during the task could have the lesser energy consumption completing a task. It ain't for no reason that batteries are specified in energy capacity, not power.

How so Les. Task energy equals power * time. Hence if the performance is the same, then time is equal. If time is equal and power is one half then task energy is one half as well.

This benchmark does seem an effort paid by Intel to show it is in line with the ARM field. A REAL phone benchmark would show battery life, likely not correlating so cleanly with processor choice.

In general, the relationship between performance, power and energy, as stated above, is NOT true.

Performance aside, I am disappointed in the lack of professionalism in some of the comments. This is a professional site, please treat as such. On the comments wrt power and energy, if you have the same performance at half the power then the total task energy will be half as well.

Intel and Microsoft are teaming up on the energy issue, at least starting with Haswell. I presume Atom will follow the same recipe going forward, if not already. The real question is whether Windows 8 is compelling enough to take significant market share in tablet and phone.

New Lenovo X1 carbon no difference over older 2-3 hrs. Surprised for sure.

One can argue about benchmarks all day long, but with new Haswell in Macbook Air the battery life goes from 7 to 12 hrs. Thus it is reasonable to assume that with the new Bay Trail on 22nm tri-gate Intel will have a competitive advantage over ARM.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
