Intel Atom x7-Z8750 vs Intel Pentium N4200

The Atom x7-Z8750 is a quad-core SoC for entry-level laptops and passive-cooled tablets, which has been presented in early 2016. It is clocked at 1.1 - 2.56 GHz and part of the Cherry Trail platform. Thanks to its new 14 nanometer low-power process (P1273) with tri-gate transistors, energy efficiency has been significantly improved compared to its predecessor Bay Trail. In addition to the CPU cores, the SoC offers a DirectX 11.2-capable GPU as well as a DDR3L Memory Controller (2x 64 bit, 25.6 GB/s).
Compared to the similar Pentium N3710, the Atom x7-Z8750 is tuned for less power consumption and offers less PCI-Express lanes (2 instead of 4) and less USB 3.0 ports (3 instead of 5). Furthermore, the integrated GPU clocks only at 600 (instead of 700) MHz and the memory controller supports LPDDR3-1600.
The processor cores are based on the Airmont architecture, which is basically a slightly modified shrink of the previous Silvermont core. While performance per clock has not been improved, the more efficient 14 nm process leads to a better utilization of the CPU Burst (alias Turbo Boost) and a therefore somewhat higher overall performance.
Due to the passive cooling and lower TDP, the Atom x7-Z8750 is a bit slower than the similar clocked Pentium N3710. The boost frequency of the CPU cores wont be used as long as in an average Pentium based laptop. However, if TDP and cooling are similar, the performance should be comparable. Using Windows, the CPU is adequate for everyday tasks such as Internet browsing or office applications, but may struggle in more demanding software or multitasking.
The HD Graphics 405 (Braswell) is based on the Intel Gen8 architecture, which supports DirectX 11.2 and is also found in the Broadwell series (e.g. HD Graphics 5300). With 16 EUs (Execution Units) and a clock speed of up to 600 MHz, the GPU is about twice as fast as the HD Graphics (Bay Trail), but still not powerful enough to handle demanding 3D games of 2015. The GPU also supports 4K/H.265 video acceleration.
The entire SoC is not rated with a TDP, but only an SDP (Scenario Design Power) of 2 Watt (N3710 SDP 4 Watt, TDP 6 Watt). Thus, the chip can be cooled passively.

The Intel Pentium N4200 is a quad-core SoC primarily for inexpensive notebooks and was announced mid 2016. It runs at 1.1-2.5 GHz (Single Core Burst, Multi-Core Burst max 2.4 GHz) and is based on the Apollo Lake platform. Similar to the Braswell predecessor, the chip is manufactured in a 14 nm process (P1273) with FinFETs. Besides four CPU cores, the chip also includes a DirectX 12 capable GPU as well as a DDR3L/LPDDR3/LPDDR4 memory controller (dual-channel, up to 1866/2400 MHz).
For the first time in a couple of years, Intel completely reworked the CPU architecture of the Atom series. The manufacturer advertises performance gains of roughly 30 percent, but does not reveal any specifics about the individual changes. The new Goldmont architecture should therefore be roughly on par with AMD's Beema/Carrizo-L APUs in terms of per-MHz performance, but it still far behind the more expensive Core CPUs (like Skylake / Kaby Lake).
The CPU performance of the Pentium N4200 with 4 CPU cores and a clock between 1.1-2.5 GHz should depend a lot on the cooling solution. If the chip can maintain its Boost clock, the N4200 should be about 30 percent faster than the old N3700 (Braswell) and compete with an AMD A8-7410. This means the processor is perfectly suited for daily tasks (office, browsing) as well as moderate multi-tasking.
The HD Graphics 505 (Apollo Lake) is based on Intel's Gen9 architecture, which supports DirectX 12 and is also used for the Kaby Lake / Skylake graphics adapters (like HD Graphics 520). Equipped with 18 EUs and a clock of up to 750 MHz, the performance should be roughly on par with the older HD Graphics 5300. This means only older titles like Counter-Strike: GO or Diablo 3 will run smoothly.
The chip also includes an advanced video engine with hardware support for the playback of VP9 and H.265 material (8-bit color-depth).
Similar to the predecessor, Intel specifies the TDP with 6 Watts (SDP 4 Watts – Scenario Design Power). The chip can therefore be cooled passively in theory, but SKUs with fans are possible as well.
