The Intel Atom x5-Z8350 is a power efficient quad-core SoC for Windows and Android devices (tablets and convertibles), which has been presented in February 2016. It is clocked at 1.44 - 1.92 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).
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 x5-Z8500, the Atom x5-Z8350 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. Compared to the older x5-Z8300, the Z8350 offers 80 MHz higher boost clock and therefore a similar performance. See our X5-Z8300 site for detailed benchmarks.
Using Windows, the chip is adequate for simple everyday tasks such as light browsing or Office, but not for 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 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.
Intel Celeron J3455
► remove from comparison![Intel Celeron J3455](fileadmin/_processed_/5/d/csm_intel_celeron_logo_7f13ce5572.jpg)
The Intel Celeron J3355 is a quad-core SoC primarily for inexpensive notebooks and Mini-PCs and was announced in late 2016. It runs at 1.5 - 2.3 GHz (Single Core Burst) 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 two 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 Celeron J3455 is between the mobile Celeron N3450 and Pentium N4200 in the lower range of mobile processors. Therefore, the CPU is best suited for light tasks with not much multitasking (office, browsing).
GPU Performance
The HD Graphics 500 (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 12 EUs and a clock of up to 750 MHz, the performance should be roughly on par with the older HD Graphics (Braswell). This means only older and simpler titles 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
The Celeron J3455 is specified at 10 Watt TDP and therefore 4 Watts higher than the slightly faster Pentium N4200.
