1. Navi 10 – The RDNA Revolution (RX 5700 Series)

Key Features:

• Architecture: RDNA 1 (7nm) – AMD’s radical departure from GCN
• Die Size: 251 mm² | Transistors: 10.3 billion
• Compute Units: 40 CUs (2,560 Stream Processors)
• Clock Speeds:
  • Base: 1,605 MHz (5700) / 1,655 MHz (5700 XT)
  • Boost: 1,725 MHz (5700) / 1,905 MHz (5700 XT)
• Memory: 8GB GDDR6 (256-bit bus, 448 GB/s)
• TDP: 180W (5700) / 225W (5700 XT)

Technical Innovations:
✅ New CU Design: 1.25x IPC uplift over GCN
✅ PCIe 4.0 Support: First consumer GPU with 16GB/s bandwidth
✅ Dual Compute Units: Improved instruction parallelism

Performance Target:

• 1440p Ultra Gaming (Competed with RTX 2060 Super/2070)
• Content Creation: 8GB VRAM for light workstation tasks

Notable Models:

• RX 5700 XT (Full Navi 10, 40 CUs)
• RX 5700 (36 CUs, cut-down variant)

Legacy Issues:
⚠️ Blower Cooler: Reference models ran hot/noisy
⚠️ No Hardware Ray Tracing: RDNA 2 would add this later

2. Navi 14 – The Efficiency Play (RX 5500 XT)

Key Features:

• Architecture: RDNA 1 (7nm) – Scaled-down design
• Die Size: 158 mm² | Transistors: 6.4 billion
• Compute Units: 22 CUs (1,408 Stream Processors)
• Clock Speeds:
  • Base: 1,607 MHz | Boost: 1,845 MHz
• Memory: 4GB/8GB GDDR6 (128-bit bus, 224 GB/s)
• TDP: 130W (No external power needed for some models)

Design Focus:
✅ Small Form Factor: Ideal for ITX builds
✅ PCIe 4.0 x8: Sufficient for 1080p (but bottlenecked on PCIe 3.0)
✅ Power Efficiency: 30% better perf/watt vs. Polaris

Performance Target:

• 1080p High Settings (Competed with GTX 1650 Super)
• eSports: 100+ FPS in titles like Fortnite, CS2

Notable Models:

• RX 5500 XT 8GB (Premium variant)
• RX 5500 XT 4GB (Budget OEM option)

Limitations:
⚠️ PCIe 3.0 Penalty: x8 link = 50% bandwidth loss on older systems
⚠️ 4GB VRAM: Struggled with modern textures

Why These Dies Mattered

1. Navi 10 Proved RDNA’s Viability
   • Demonstrated AMD could compete at $400 price point
   • Set stage for RDNA 2’s Infinity Cache
2. Navi 14 Filled Critical Gaps
   • Replaced aging Polaris in budget segment
   • Showcased 7nm efficiency for laptops (RX 5300M)

Legacy: While lacking ray tracing, RDNA 1 delivered:

• 57% better perf/watt vs. GCN (Vega)
• PCIe 4.0 foundation for future GPUs
• Driver longevity (Still supported in 2024)
