⚙️ Blackwell Architecture: Silicon-Level Analysis

1. Process Node & Transistor Density

• TSMC 4N+ (Enhanced 4N):
• Density: 136MTr/mm² (vs. 100MTr/mm² in Ada Lovelace)
• SRAM Cache: 128MB L2 (RTX 5090) vs. 96MB (RTX 4090)
• Clock Scaling: 3.5GHz achievable at 1.1V (vs. 1.05V on AD102)

2. SM (Streaming Multiprocessor) Changes

• New FP32 Units: Dual-issue FP32+INT32 pipelines (vs. concurrent in Ada)
• Ray Tracing Cores: 4th Gen (75% faster BVH traversal)
• Tensor Cores: 5th Gen (2.3x TOPS/mm² vs. Hopper)

3. Memory Subsystem

GPU	Bus Width	Bandwidth	Latency (ns)	ECC Support
RTX 5060	128-bit	288 GB/s	180	No
RTX 5070	192-bit	648 GB/s	160	Partial
RTX 5080	256-bit	1.15 TB/s	140	Full
RTX 5090	384-bit	1.73 TB/s	120	Full

📌 Note: GDDR7 uses PAM3 signaling (36Gbps effective) with on-die ECC for error correction.
