IT之家 10 月 1 日消息,IT之家家友 @白饭炒白米饭 昨日(9 月 30 日)发布动态,分享了苹果 A20 标准版芯片的焊点图,该芯片将会装备在 iPhone 18 标准版机型上。

iPhone 18 标准版首秀:苹果 A20 芯片焊点图曝光,推测 5 核 GPU

IT之家附上帖子内容如下:

有了 Apple A20 标准版芯片的焊点图,现在可以进一步推测 A20 的芯片规模了。

1、制造工艺,因为与 A20 Pro 同代,因而用的是台积电 N2 工艺制造。

2、芯片面积,已知 A20 Pro 裸 Die 面积 98.80mm²,A20 的话大概是在 70~80mm²,比 A19 要小。

3、内存封装,从焊点图来看,A20 仍旧使用传统的 PoP 封装,不是 A20 Pro 的 WMCM 封装,散热压力仍旧存在。

4、GPU 执行单元,对应背部电容 1 位置,勉强可以放下 6 个核心,考虑 GPU 前端和 GPU 缓存也要位置,因而 GPU 数量大概率还是 5 核,结合历代标准版都有频率限制,A20 的 GPU 频率估计也会有所限制。

5、CPU 执行单元:对应背部电容 2、3 位置,分别是两个大核和四个小核,预计大核共享 8MB L2、小核共享 4MB L2,考虑到端侧 AI 的需要,SLC 可能从 A19 的 12MB 增加到 16MB。

6、神经网路引擎,对应背部电容 4、5 位置,双 16 核的神经网络引擎,专用 4MB 缓存。

7、内存控制器,对应背部电容 6、7 位置,结合焊点图布局,Die 是偏左放置,右边留出更多空间应该是考虑了布线,因而 6 号位置对应一组 LPDDR 控制器,7 号位置对应两组,每组 32bit,合计 96bit。

将以上这些推测对应到焊点图上后,如配图所示,A20 标准版芯片预计明年搭载在 iPhone 18 上,总体属于是常规升级,表现释放不会像 A20 Pro 那样激进,进一步拉开 A 芯片标准版与 Pro 版之间的表现差距。

基于上述推测信息,IT之家简要制作比较表格如下:

On October 1, IT House reported that home user @BaiFanChaoBaiMiFan shared a solder point diagram of the Apple A20 standard chip. This chip will be equipped in the iPhone 18 standard model.

Apple A20 chip for iPhone 18 standard edition revealed: solder point diagram suggests 5-core GPU

IT House attaches the post content as follows:

With the solder point diagram of the Apple A20 standard chip, we can further speculate on the scale of the A20.

1. Manufacturing process: Since it is in the same generation as the A20 Pro, it uses the TSMC N2 process for fabrication.

2. Chip area: The A20 Pro has a bare die area of 98.80 mm², while the A20 is estimated to be between 70-80 mm², smaller than the A19.

3. Memory packaging: From the solder point diagram, the A20 still uses the traditional PoP packaging, not the A20 Pro's WMCM packaging. The cooling pressure still exists.

4. GPU execution units: Corresponding to the back capacitor position 1, it can barely fit 6 cores. Considering the space needed for the GPU frontend and cache, the GPU count is likely still 5 cores. Combined with historical frequency limitations on the standard version, the A20 GPU frequency is also expected to be restricted.

5. CPU execution units: Corresponding to the back capacitor positions 2 and 3, there are two large cores and four small cores. The large cores are expected to share 8 MB L2, and the small cores 4 MB L2. To meet the requirements of edge AI, the SLC might increase from the A19's 12 MB to 16 MB.

6. Neural network engine: Corresponding to the back capacitor positions 4 and 5, there is a dual-16 core neural network engine with a dedicated 4 MB cache.

7. Memory controller: Corresponding to the back capacitor positions 6 and 7. Looking at the solder point layout, the die is shifted left, leaving more space on the right, likely for routing. Position 6 corresponds to a single LPDDR controller, and position 7 to two groups (32 bits each), totaling 96 bits.

Based on these speculations, the A20 standard chip, expected to be in the iPhone 18 next year, represents a conventional upgrade. Its performance release will not be as aggressive as the A20 Pro, further widening the gap between the standard and Pro versions of the A chips.

Based on the above information, IT House presents a comparison table:
