Snapdragon X Leak: 12-Core CPU, CPU & Cache Take 1/3

Recent leaks have revealed the internal structure of Qualcomm's Snapdragon X processor, showcasing its 12 CPU cores and substantial cache size. The overall chip measures 169.6 mm², slightly larger than Apple's 10-core M4 chip, which is 165.9 mm².

According to the leaked images, the Snapdragon X processor features 8 high-performance Phoenix cores, each running at a frequency of up to 3.80 GHz, with individual core areas around 2.55 mm², smaller than Apple's M4 cores, which are 3 mm². The processor also includes two 12-way, 12MB L2 caches, each covering 6.1 mm². Additionally, it has four smaller Phoenix cores, also supported by 12-way, 12MB L2 caches. The 12 cores share a 6MB system-level cache, measuring about 5.09 mm².

In total, the 12-core CPU occupies around 48.2 mm², while the combined cache adds up to 54MB, taking up approximately 15 mm², which accounts for about one-third of the core's total area.

In comparison, the Snapdragon X's GPU, the Adreno X1, is significantly smaller at 24.3 mm² but still delivers impressive performance. Qualcomm has previously stated that the Adreno X1 offers raw performance of 4.6 FP32 TFLOPS, slightly lower than Nvidia's GeForce RTX 3050, which reaches 4.8 FP32 TFLOPS. The GPU also integrates more than 12MB of cache, spread across various levels.

Furthermore, the Snapdragon X includes a 128-bit LPDDR5X-8448 memory interface, display controller, ISP, NPU, and other specialized components not detailed in the image.
