The i5 in this machine is not the i5-7200U. It's actually the i5-7Y54, which is a rebranded m5 mobile CPU. Intel rebranded the m series, except for the m3, to move it under the umbrella of the "i" line. Just like the m5, this CPU is a 4.5TDP (thermal design power) which means, on average, it uses less power than the 7200U (15w TDP). It's truly a "mobile" processor. The GPU on this set is also lower than the 7200U, as an Intel 615 is on board. The CPU is capable of overclocking to 3.2GHz using Intel's "Turbo Boost" but it's not a sustained speed for regular use. It's a fine machine for regular household and for something lightweight and portable, but the CPU benchmarks have shown the i5 more efficient with power management, even though it's power draw is higher.
