Xiaomi's self-developed Xuanjie O1 was released on the evening of May 22. Let's just look at the performance test of Xuanjie O1.

Comparison of CPU, GPU and flash memory reading and writing speed with Snapdragon 8 Premium, Tianji 9400, Apple A18 Pro and other chips (see the length of the color bar to know the strength ratio) ↓

Focus on the results of the modified GeekBench 5 and RAR tests (the latter mainly tests the L2 cache performance of the CPU). These two tests are not in the white list of running scores, and they can represent the performance output that can be used daily.

Xuanjie O1's current scheduling has exceeded some conservative Snapdragon 8 Ultimate models in daily output ↑

Streamless version:
- CPU single core performance : Apple A18 Pro>Snapdragon 8 Ultimate>Xuanjie O1>Tianji 9400
- CPU multi-core performance : Snapdragon 8 Ultimate>Xuanjie O1>Tianji 9400>Apple A18 Pro
-  GPU performance : Tianji 9400>Snapdragon 8 Ultimate>Xuanjie O1>Apple A18 Pro

Chip architecture analysis of Geek Bay ↑

Xiaomi Xuanjie O1, TSMC's second generation 3nm (N3E) process, 19 billion transistors, 109mm ² chip area (smaller than A18 Pro without integrated baseband, more significantly smaller than Tianji 9400 and Xiaolong 8E with baseband), 10 core 4 cluster design:

• Dual 3.9GHz X925 super core (2MB L2 cache)

• +Four 3.4GHz A725 (1MB L2 cache)

• +Two 1.9GHz A725 (1MB L2 cache)

• +Two 1.8GHz A520 (sharing 512KB L2 cache)

A total of 10.5MBL2 cache+16MB L3 cache is designed without SLC system cache (possibly to reduce power consumption under low load).

GPU is Immortalis -G925 MC16 1.392GHz It has its own 4MB L2 cache, which is the same generation as Tianji 9400 (Fage Tianji 9400 is MC12 @ 1.612GHz). It has four more cores, but its performance cannot match Fage+and its peak power consumption is 1/3 higher, which may be related to the lack of SLC cache.

4 nm process of external platform SMDC MediaTek T800 5G baseband 6 core self-developed NPU has 10MB cache and 44TOPS computing power; Xiaomi's fourth generation self-developed ISP image processor (dual hardware computing units, which can be directly called by third-party applications. The self-developed ISP will appear on Ultra and MIX in 2021).

Multi core energy efficiency: The 10W Inner Xuan Ring O1 is stronger, slightly stronger than the Snapdragon 8 Ultimate Edition and A18 Pro, and obviously stronger than the Tianji 9400. The energy efficiency and performance of the single core X925 is stronger than that of Fage, The energy efficiency of the CNNC A725, even the X4>of Gan Fanfa, killed the CNNC of the Snapdragon 8E and the A720 of the Double Killing Tianji 9400 in almost the whole process.

The low-frequency A720 even exceeded the energy efficiency of the A18 Pro's energy efficiency core, breaking the record, so in the actual game, it was basically running on six A725.

Xiaomi 15S Pro (Xuanjie O1) is really the same as Xiaomi 15 Pro (Snapdragon 8 Ultimate Edition). For the first flagship SoC (Xiaomi's second) of new players, "it is almost the same as the Snapdragon 8 Ultimate Edition" is the highest praise.

It may be because of the external baseband, the endurance of the Xiaomi 15S Pro is slightly weaker than that of the Xiaomi 15 Pro. This may also be one of the reasons why Xiaomi desperately optimizes low load power consumption.

In addition 3.7GHz Xuanjie O1 : It can be seen in the millet tablet 7 Ultra, double 3.7GHz X925+4 3.04GHz A725+2 1.89GHz A725+2 1.8GHz A520.

In addition Xuan Ring T1 The watch chip of, with a self-developed 4G baseband, can be found in the REDMI Watch 5 eSIM Edition and the Xiaomi Watch 4 eSIM 15th Anniversary Special Edition.
