The OPPO K series mobile phone + TV set released earlier this year also impressed us. Recently, OPPO launched the OPPO K9-OPPO K9x sequel which has further improved the configuration and could be called the US $ 157.33 Bucket Machine.

Udemix already got Silver and Purple Super Dream color matching. In the next article, the author will show you the performance of this phone in a comprehensive manner.

Appearance Design

The OPPO K9x adopts OPPO’s classic rounded body + square matrix design style in the top left corner and also incorporates a unique lens texture process with the color Super Dream Purple. The overall look and feel are very smart and youthful. The dimensions of the fuselage are 159.1 x 73.4 x 7.9 mm, and the weight is 191 grams. Due to its narrow width and lightweight, it feels very comfortable to hold. Although it is small in size and light in weight, it is still equipped with a massive 5000mAh battery, and the battery life should be quite impressive.

The front of the OPPO K9x sports a 6.5-inch FHD+ 90Hz resolution LCD Digging screen, with a screen ratio of 20:9. It supports a high sampling rate of 180Hz and is easy to operate. One of the bright spots on this LCD screen is its relatively high brightness.

The measured manual maximum brightness can reach 410nits, and the excitation peak brightness can reach 600nits. which can be seen in the sun. Compared to most OLED screens, LCD screens are more eye-friendly. But the chin will be thick and there will be no screen fingerprint, so the OPPO K9x adopts a side fingerprint design.

The design of the OPPO K9x incorporates some of OPPO’s accumulated craftsmanship. “Silver Purple Super Dream” is based on light blue and purple. The lens texture process beats the lower backplate at various angles with changing shades of light and shadow, as well as a touch of silver metallic texture. Hard-core technology is full of understanding. Moreover, the special textured matte back cover made on the surface of the back cover makes the back cover feel comfortable to touch and does not cling to fingerprints.

The top left corner of the back cover houses a 6400W pixel three-camera module. The red dot which is the final touch and the transparent cover on the right complement each other. The look and feel are very trendy and trendy.

The frame is made of plastic material. It’s a very honest thing. That its SIM card slot supports TF card expansion, and it is not a choice of two. Dual cards and TF cards can be used at the same time. Which can greatly reduce the cost of the machine and make it more cost-effective.

Balanced performance, ultra-low power consumption

OPPO K9x is equipped with Dimensity 810 processor. Dimension 810 is built with TSMC 6nm process, octa-core CPU architecture design. With 2 Arm Cortex-A76 cores, clocked at 2.4GHz, with Mali-G57 GPU, the power consumption is very low.

To achieve superior continuous-release performance, the OPPO K9X uses graphite tube, graphite sheet, and copper foil to form a hardcore heat dissipation module composed of three high thermal conductivity materials. The Dimension 810 processor doesn’t generate as much heat natively, so it’s a more stable release.

Apart from this, the Color OS of Oppo K9x also has memory expansion technology enabled by default. Which can call passive flash memory to provide up to 5G of additional storage. Which makes the situation of hitting the background very easy.

OPPO K9x 5g GeekBench Score

In Geekbench5, which represents the theoretical performance of the CPU. The Oppo K9X scored single-core 612 and multi-core 1820, which is basically the same as Snapdragon 845 and can meet daily smooth usage.

In 3DMark Wildlife Stress, which emphasizes GPU performance. The OPPO K9x got the highest score of 1247 and the lowest score of 1245 with a stability of 99.8%. Even over long periods, there is almost no frequency reduction in the display output. It can be seen that the Dimension 810’s heat is quite low.

The flash memory running score in Androbench is shown in the figure:

Showcasing a comprehensive display in the AnTuTu V9, the OPPO K9x scored 388,846 points, which performed quite well in the Dimensity 810 mobile phone.

From the above theoretical data, the performance of Oppo K9x is still good. Thanks to its excellent heat dissipation and low power consumption, even a high-intensity run, and the baking machine’s body temperature exceed 30 degrees. very quiet.

OPPO K9x 5g Heat Test

Next, let’s take a look at its performance in the actual game. First, the latest “League of Legends Mobile Games” national server. This game is not a very tasty configuration. We went straight to the highest quality 60 frames to play Polar Fight. It’s still stable throughout the 60 frames, with no frame drops during play, and no heat in the hands.

As can be seen from the above, the mainstream mobile game Dimension 810 can easily cope with this. Even if it is too lazy to send heat, the whole process is stable and full of frames. The only problem now is that the high frame rate mode is not fully optimized. Which ruins the performance. So can the tensest “Original God” be played easily? We moved to a minimum of 60 frames of special effects.

Although the picture quality is not good. But there is no problem with running smoothly. The average frame rate for the last 30 minutes is 48 frames. This frame rate is the highest among all the Dimensity 810 phones tested. The OPPO K9x has two brushes.

The average power consumption for 30 minutes is only 3200mW. At room temperature of 20 °C, the hottest part of the whole machine is only 38 °C. This can be called ice-cold and no matter how you play, the frequency will not decrease.

Ultra-low power consumption means longer battery life. Apart from this, the OPPO K9x is also equipped with a massive 5000mAh battery. 56 percent power is left even after three and a half hours of gaming + running points. Which is used daily. No problem all day long.

Although it is posted for one thousand Rupee machine. The Oppo K9x is still equipped with a decent 33W Super Flash Charging experience. After the actual measurement by the Udemix, it can be charged to 50% in about 30 minutes and 100% in about 70 minutes. Slow charging is used. Quick.
