Intel Atom x7-Z8700 vs Intel Pentium N4200

Intel Atom x7-Z8700

► remove Intel Z8700

The Intel Atom x7-Z8700 is a power efficient quad-core SoC for Windows and Android devices (tablets and convertibles), which has been presented in March 2015. It is clocked at 1.6 - 2.4 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-T (e.g. Atom Z3795). In addition to the CPU cores, the SoC offers a DirectX 11.2-capable GPU as well as a LPDDR3 Memory Controller (2x 64 bit, 25.6 GB/s).

Architecture

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.

Performance

Compared to the Atom Z3795, the Atom x7-Z8700 offers about 5 percent more performance and is similar fast as an AMD A6-6210 APU or high-end ARM SoCs, e.g. the Snapdragon 810 or Exynos 7420.

Using Windows, the performance is adequate for everyday tasks such as Internet or Office, but not for very complex software or modern games.

Graphics

The HD Graphics (Cherry Trail) 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) and will handle older and less demandig Windows games (e.g. Counter-Strike: GO) in low settings at decent frame rates. The GPU also supports 4K/H.265 video acceleration.

Compared to ARM SoCs, the HD Graphics offers a performance somewhere between the Qualcomm Adreno 330 / PowerVR G6430 and the Adreno 420 / PowerVR GX6450.

Power Consumption

The entire SoC is rated at an SDP of 2 watts, which indicates a TDP of less than 4 watts. Thus, the chip can be used in passively cooled tablets.

Intel Pentium N4200

► remove

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).

Architecture

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).

Performance

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.

GPU Performance

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).

Power Consumption

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.
