Intel Atom x5-Z8300

Intel Z8300

The Intel Atom x5-Z8300 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 1.44 - 1.84 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 over 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).


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.


Compared to the Atom x5-Z8500, the Atom x5-Z8300 is clocked slightly lower and therefore about 10 percent slower. However, the x5 still beats many ARM-based SoCs and offers a performance similar to a Qualcomm Snapdragon 801

Using Windows, the chip is adequate for simple everyday tasks such as light browsing or Office, but not for complex software or modern games.


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 12 EUs (Execution Units) and a clock speed of up to 500 MHz, the GPU is significantly faster as the HD Graphics (Bay Trail) and can handle at least some older and less demandig Windows games in very low settings. The GPU also supports 4K/H.265 video acceleration.

Compared to ARM SoCs, the HD Graphics offers a performance sligthly below a Qualcomm Adreno 330 or PowerVR G6430.

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.
