我想知塊 PCB 要去到幾多層呢？

肯定好足層數先。

5xx mm^2 (23.xx * 23.xx) 嘅 die size 都唔會細食得去邊啦啩？

nVidia GT300's Fermi architecture unveiled: 512 cores, up to 6GB GDDR5

GPU specifications
This is the meat part you always want to read fist. So, here it how it goes:

* 3.0 billion transistors
* 40nm TSMC
* 384-bit memory interface
* 512 shader cores [renamed into CUDA Cores]
* 32 CUDA cores per Shader Cluster
* 1MB L1 cache memory [divided into 16KB Cache - Shared Memory]
* 768KB L2 unified cache memory
* Up to 6GB GDDR5 memory
* Half Speed IEEE 754 Double Precision

如果是真的話，單卡的效能最少是5870的一倍多
