Jumper ECZBOOK X4
Intel Gemini Lake processor
At the end of 2017, Intel gave the go-ahead for processors in the Gemini Lake series. At the beginning of June one of the first notebooks with the new Intel Gemini Lake N4 appeared with the Jumper EZBOOK X4100. Like the "Apollo Lake" predecessor series, the system-on-chip (SoC) is manufactured using the 14 nm process.
In the base clock, the 4 cores of the processor achieve a clock rate of 1.1 GHz. A maximum clock rate of 2.4 GHz is reached in the burst. Compared to the Intel Apollo Lake N3450 of last year's EZBOOK 3L Pro, the new N4100 SoC promises a slight increase in performance thanks to a 200 MHz higher burst clock. Ultimately, however, the cooling performance of the EZBOOK X4 is decisive. It remains to be seen how much Jumper has the SoC under control.
The memory is 4GB DDR4L RAM, which can be expanded up to 8GB. A 128GB SSD is installed as data storage. The SSD is type M.2 and is therefore most likely replaceable. The SoC's processor graphics are called "Intel UHD Graphics 600". The GPU should definitely be able to cope with one or two games. Of course, the GPU decodes VP9 and H.265 video material at the hardware level.
Design and display
With dimensions of 33.30 x 22.00 x 1.30 cm and a weight of 1.36 kg, the notebook is kept comparatively compact. Jumper once again relies on aluminum for the housing material. A special design feature is the illuminated chiclet keyboard with 20 mm keycaps. As with the previous models, the notebook is only available with a US keyboard layout. A trackpad is typically located below the keyboard. The side connection options amount to two USB 3.0 sockets, a Micro-HDMI socket, a MicroSD memory card slot, a 3.5 mm jack audio socket and a DC power input.
The display has a diagonal of 14 inches in Full HD (1920 x 1080 pixels). The panel is of type "TN". The disadvantages of this panel type compared to the commonly used IPS / VA panels are lower viewing angle stability and less accurate color reproduction. Jumper probably decided to use a TN panel for cost reasons, as they are significantly cheaper to produce. The display bezel is a moderate 8 mm. There is a 2 megapixel front camera above the display. Two additional microphones make it possible to use the laptop for (video) telephony.
Battery and others
The battery has a capacity of 9600 mAh. Experience has shown that the running time should be at least 5 hours under normal conditions of use. Windows 10 is preinstalled as the operating system. The wireless transmission takes place with the help of Dual Band AC WiFi and Bluetooth 4.2.
