On December 23, MediaTek Tianji 8400 officially released its first A725 architecture, and all eight CPU cores are A725. It will be launched by the REDMI Turbo 4 (Tianji 8400 Ultra), and it is also officially announced that there will be a new Tianji 8400.
Tianji 8400 is the second generation 4nm (N4P) process of TSMC;
[CPU] The second generation first launched the A725+full core architecture (the same generation as the X925 super core architecture of Tianji 9400);
One 3.25GHz A725 (1MB L2)+three 3.0GHz A725 (512KB L2)+four 2.1GHz A725 (256KB L2) (the cache configuration of the three core clusters is consistent with Tianji 9300);
L2 cache doubles to 1MB, 6MB L3 cache+5MB SLC cache (the previous generation was 4MB+4MB);
A725 claims that the single core performance has been improved by 10%, and the same function has been reduced by 35%. There is also SVE2;
Support 8533Mbps LPDDR5x memory+UFS 4.0 flash memory;
The peak performance of the previous generation can be reached with 56% power consumption of the previous generation). Declare that chat power consumption is reduced by 14%, game power consumption is reduced by 24%, and video recording and music power consumption is reduced by 12%;
The [GPU] is the Mali-G720 MC7 1.3GHz, with 40% bandwidth optimization and hardware optical tracking (not all Mali-G720s have optical tracking).
The peak performance is improved by 24%, and the power consumption of the same function is reduced by 42% (the peak performance of the previous generation can be reached with 58% power consumption), which is 44% better than that of the friend (Snapdragon 8s Gen 3?);
[NPU 880] performance increased by 54%, and the Zurich V6 scored 3877 points;
[ISP Imagiq 1080] supports up to 200 million pixel CMOS and 4K 60fps HDR video recording, and has a QPD focusing hardware engine (like a 2x2 OCL sensor);
Bluetooth 5.4+WiFi 6E, VP9 and AV1 hard solutions;
The GeekBench 6 multi-core of Tianji 8400 scored 6722 points (increased by 32%), and the Anthare scored 1.806 million points. The Snapdragon 8G2 is 160W, the Snapdragon 8G3 is 200W, and the Tianji 9300 is 220W.
REDMI Turbo 4 will launch Tianji 8400 Ultra (official announcement after New Year's Day) for the first time, and also provide the energy efficiency curve - within 4W (corresponding to daily load). The energy efficiency of Tianji 8400 is higher than that of Snapdragon 8 Gen 3, and the previous generation Tianji 8300 has been suspended in almost all power consumption segments.
PS： In the domestic application ecology, various APPs have high performance requirements. The A510/A520/A55 small cores are just a drag. The lower the proportion of such small cores, the better the actual energy efficiency will be (the more large cores, no core will run in the range of lower frequency and higher energy efficiency).
The Tianji 8400 will be launched by [REDMI Turbo 4], which will see you in January next year (officially announced on New Year's Day).
Specifications of [REDMI Turbo 4]: plastic middle frame+glass back cover+short focus fingerprint, 1.5K LTPS straight screen, 6500mAh battery+90W fast charge, 50 million pixel main camera, IP68 protection.
PS： The Redmi Turbo 3 released on April 10, 2004 is a Snapdragon 8s Gen 31999 yuan.
On the same day, the real me also announced that there would be a new Tianji 8400, which could be the real me Neo7 SE? (It will be the same mold as the real person Neo7, and also the 7000mAh battery? After all, the previous generation Neo6 and Neo6 SE shared the same mold).
Finally, Tianji 8400, and SoC information from Snapdragon 8 Supreme Edition, Tianji 9400 to Snapdragon 8s Gen 3/Snapdragon 7+Gen 3 ↓
