Surge S1: Xiaomi Mi5c with its own SoC, Redmi 4X for small money

Surge S1: Xiaomi Mi5c mit eigenem SoC, Redmi 4X für kleines Geld

Xiaomi has today presented its own system-on-a-chip, which in the run-up as “Pinecone” rumored in rumors. The new medium-class chip is plugged directly into a smartphone, the Mi5c. Add to this the favorable Redmi 4X with Qualcomm hardware.

With the new Surge S1 named SoC, Xiaomi will be similar to Apple, Samsung and Huawei, all of which develop their own chips, become independent of third-party suppliers. In addition, the optimization of hardware and software can be improved. According to Xiaomi it took 28 months until the SoC from the conception the way into a device finds. The Surge S1 is thereby a SoC of the middle class, which in some places still remains behind the competitors.

28 nm and eight cores

This is mainly the case with lithography: Xiaomis chip is still manufactured in 28-nm HPC. The competition models, above all the Qualcomm Snapdragon 625 from the Moto Z Play or the HiSilicon Kirin 655 from the Huawei P8 Lite 2017, are already manufactured in 14 and 16 nm, respectively. As CPUs the Surge S1 puts on eight cortex A53 cores in two quadruplets. Xiaomi uses ARM’s big.LITTLE architecture. The high-performance cluster clocks with a maximum of 2.2 GHz, the power-saving cluster with a maximum of 1.4 GHz. The GPU comes with an ARM Mali-T860, which according to the benchmarks of Xiaomi in the GFXBench on the Adreno 506 in the Snapdragon 625 precedes. Memory is connected with LPDDR3 and internal memory with eMMC 5.0.

Camera should benefit

Other features include a programmable modem that can be updated via software and a digital signal processor with voice over LTE support. Xiaomi also particularly emphasizes the options for the camera: The Surge S1 has two image processors (Dual-ISP). On the one hand, integrated algorithms should ensure a 150% increase in light sensitivity and reduced noise in poor light conditions. The compression of loss-free image data is also expected to require 50 percent less bandwidth and image processing 15 percent less power.

Mi5c is the first smartphone with Surge S1

The new SoC is integrated in the Xiaomi Mi5c, a new medium-class model, which is based on the last-year flagship Mi5. The SoC to the side are 3 GB RAM and 64 GB of internal memory according to eMMC 5.0. Unlike many other smartphones from Xiaomi, the Mi5c comes to the current state only in this one storage variant. In addition to the Surge S1, Xiaomi installed a 5.15-inch display with full-HD resolution. This should be up to 550 cd / m² bright and due to very precise brightness control 2.048 brightness levels. The color space coverage is indicated by 94.4 percent according to NTSC. Beneath the display is a fingerprint sensor as with the Mi5.

For power, a 2,860 mAh battery, which is charged according to Xiaomi with 9 V / 2 Ampere fast. This is done via USB 2.0 type C. The technology packs Xiaomi in a metal housing that is only 7.09 millimeters thin and weighs 132 grams. Xiaomi does not give the Android version, only the indication that Android 7.1 will be available in March in a developer ROM is known. What is certain is that the Mi5C is set to MIUI 8 as a surface.

Xiaomi highlights the camera

In line with the technology of the Surge S1, Xiaomi also advertises the camera of the new Mi5c. The camera should be able to absorb a lot of light and together with a pixel size of 1.25 μm provide good results in poor light conditions. For comparison, the pixel size of the Samsung Galaxy S7 (edge) is 1.4 μm, that of the Google Pixel (XL) at 1.55 μm. In terms of size, ComputerBase has tested in an extensive comparison test of current smartphone cameras. With the use of the Surge S1, the Mi5c should also benefit from the aforementioned algorithms for image processing. By 14-Bit color depth the photos are also to convince also in the color presentation. The focus is on phase comparison.

Cheap entry model Redmi 4X

In addition to the Mi5c, Xiaomi has also introduced the favorable Redmi 4X. This comes with a Snapdragon 435 with eight Cortex A53 cores and a maximum of 1.4 GHz clock rate as well as two memory variants: 2 GB RAM and 16 GB internal or 3/32 GB. Unlike the Mi5c, the memory can be expanded by up to 128 Gbyte using a microSD card.

The camera of the Redmi 4X solves with 13 megapixels, the aperture is f / 2.0 larger than the Mi5c with f / 2.2. The battery is also considerably bigger with 4,100 mAh. On the other hand, the screen is backed up: the 5-inch panel resolves with 720 × 1,280 pixels and, unlike the Mi5c, offers only 72 percent coverage on the NTSC scale.

Prices and availability

Both models appear in the colors rose gold, black and gold. The Xiaomi Mi5c costs around 206 euros (1,499 yuan). The Redmi 4X costs 96 (699 yuan) or 123 euros (899 yuan) depending on the storage option. Both models are expected to come on the market in March.
