Re: Intel lied at CES about TDP?
The article cited is here - »www.anandtech.com/show/6655/inte···ystified
It appears SDP is used as a tablet estimated power consumption measurement. It is unlikely a tablet will be stressed the same way a PC or laptop would be. Note also, the range in TDP is 10 watts to 13 watts, not 13 watts. 7 to 10 watts SDP to TDP is a big deal, but 7 to 13 watts is the outlier not an average.
I agree with the sentiment, Intel should have been more upfront about changing it's measurement. At the same time, Intel may have a legitimate basis for doing so. As tablets, and eventually cell phones are unlikely to be driven as hard as desktops.
From the above link -
If Intel is taking it's CPU with integrated GPU to places beyond it's normal market, using a similar measurement to chips in that market may make sense.
The best comparison I can make is to the data we saw in our last power comparison article. Samsung's Exynos 5 Dual (5250) generally saw power consumption below 4W, but during an unusually heavy workload we saw it jump up to nearly 8W. While Samsung (and the rest of the ARM partners) don't publicly specify a TDP, going by Intel's definition 4W would be the SoC's SDP while 8W would be its TDP if our benchmarks were the only ones used to determine those values.
