On March 6, Xiaomi's official website updated the price of maintenance parts for Xiaomi 15 Ultra, which is very interesting.
In fact, the cost of the two generations of models cannot be compared accurately. Let's compare them for entertainment:
• The motherboard costs 210 yuan (The cost of Snapdragon 8 Premium does not seem to be expected to be medium to high) (memory and flash memory also have changes)
• 70 yuan cheaper for the main camera after removing the variable aperture
• 30 yuan and 40 yuan for triple telephoto and ultra wide-angle. Both generations did not include ultra long focus, may it be included in the price of "ultra wide angle"? (But the cost of telephoto is not as low as that.)
• After the battery is upgraded, it is still 179 yuan, Fiberglass back cover is 20 yuan cheaper than Konapi back cover
• The screen price remains unchanged at 1350 yuan.
The 6000mAh carbon negative battery that can charge 90W fast is only 179 yuan, while the 4685mAh battery of the iPhone 16 Pro Max has a replacement price of 969 yuan (5.4 times the price), which has been able to replace a 1-inch LYT-900 camera for the Xiaomi 15 Ultra.
Only Apple can dooooo！
The apple pit returns to the pit, but the M-series chip is really fierce.
On March 5, Apple released the new M4 version of MacBook Air and the new M3 Ultra MacStudio.
[M4 MacBook Air] is a core replacement upgrade, mainly in multi day blue. The beggar version is an 8-core GPU M4, and the rest are 10 core full blood versions:
The 13 inch version starts at 7999 yuan (16+256), and the 15 inch version starts at 9999 yuan (16+256).
On March 6, they all went to the state for compensation. The 13 inch version of the M4 MacBook Air is 6367 yuan after the national compensation, and the 15 inch version is 7959 yuan.
Because of the existence of M4 and 16GB gold memory, the 13 inch MacBook Air with less than 6400 yuan suddenly looks very fragrant.
【Mac Studio】
M4 Max, from 36G+512G, from 16499 yuan
M3Ultra, starting from 96G+1T, starting from 32999 yuan
No mistake, The strongest Apple chip in 2025 is M3 Ultra, not M4 Max (Apple's official reply suggests that there may be no M4 Ultra). Because of its huge core size, the M3 Ultra is much better than the M4 Max in performance.
The top configuration of M3 Ultra is a 32 core CPU+80 core GPU, with 184 billion transistors, and supports up to 512GB of unified memory (It can be used as video memory, and AI users can't keep their legs together. However, it will cost 30000 yuan to buy).
Even the M3 Ultra in the blood wreckage version is 28 core CPU+60 core GPU with 819GB/s memory bandwidth.
[Digital transistor] What is the concept of the 184 billion transistors of M3 Ultra full blood version? Its number of transistors is double that of all its contemporaries, including 5090:
2 times of RTX5090, 2 times of M3Max and 5 times of M3 Pro
11.5 times of M1, 9.7 times of A17Pro and 11.5 times of A16
