December 27, since 2006, chip giant Intel was gradually occupied the
processor market absolute dominance. However, the beginning of this
century, it has also been AMD's Athlon 64 processor beaten thoroughly
discredited. To avoid repeating the mistakes of the past, Intel has
begun to take a "step-by-step the camp" secure strategy. Now it is the
brilliant achievements, of course, can not be separated from its
continuously updated processor architecture, as well as the huge
investment in chip manufacturing plant, but really plays a decisive role
in it is its internal performance modeling team.
With the rise
of the ultra-thin mobile device market, the focus of the industry for
the processor performance gradually changed. To create a good user
experience, energy consumption began to become as important as absolute
performance. Intel also began to realize this point: the internal
performance modeling team to guide the product architecture design,
absolute performance processor is not the only goal of the user
experience, and power efficiency have become the priority factors.
Moreover,
in order to reach a better user experience, Intel is trying to
transform itself role. In close cooperation, Acer introduced the W510,
W700 two flat products and S7 ultra-extreme. Core and Atom processors
power control to the lower level for a longer product life, the next
generation Haswell processor platform, should be used on the motherboard
which non-Intel components, chip giant hardware vendors do detailed
provisions. Haswell processor to wait until after the second quarter of
2013 to the listing, the Ivy Bridge architecture strength can not be
underestimated. Earlier this year, Intel had announced early next year,
you want to Ivy Bridge power consumption to 10W or less. Reason to
believe, Ivy Bridge will be the main recent dominant market changes. The
moment we see less than Core processor equipped iPad to believe that
sooner or later this day.
Earlier, there were horizontal
evaluation: Samsung ATIV Smart PC tablet battery is only 30Wh, less than
Microsoft's Surface RT flat 31Wh former screen size of 11 inch (1366 ×
768 resolution) than the latter ( 10-inch, with a resolution of 1366 ×
768), but equipped with the Intel Atom Z2760 processor ATIV Smart PC
life better than the Surface RT. Life, ATIV Smart PC in continuous web
browser test length of 17% compared to rivals; video playback test, ATIV
Smart PC win 3%. Also done by Intel Atom and Tegra 3 processor
comparison, in their presentation, regardless of the device as a whole
or individual components, using 32nm Clover Trail architecture-power
Atom processor is better than the Tegra 3.
The reduction of the
power consumption of the end-user benefits are obvious: the running
speed of the Intel Atom processor itself must be better than the ARM
architecture Cortex A9 core Tegra 3 processor but with a four TSMC 40nm
process production Cortex A9 cores. Other hardware configuration of the
same case, the Atom processor is not only efficient and energy-saving.
In
fact, Intel does not have any special evaluation methods. They just
select the device to dismantle and to measure the energy consumption
from the level of the individual components, rather than the use of
certain software to evaluate the entire system. Typically, the device
motherboard contains a number of different components of the display,
network, storage, system-on-chip, engineers need different workload
conditions repeated attempts to identify the specific CPU or GPU power
supply filter circuit.
Under normal circumstances, the power
supply for the CPU or GPU filter circuit is a standard LC (inductance
capacitance) filter. To capture the LC filter, the series as long as in
the inductor before a very small resistance (2-20MΩ), measuring the
difference between the voltage across the resistor, and can use the
classic Ohm's law to obtain current, and further calculating power. In
support of external tools, the the specific kernel power changes for a
period of time system-on-chip can also be recorded.
