Platform Longevity: AM5 vs LGA 1700
AMD AM5: Build Now, Upgrade Later:
AMD’s AM5 platform lets you future-proof your rig with confirmed support through 2025 and rumored Zen 6 compatibility. A $150 B650E motherboard pairs perfectly with the Ryzen 7 7800X3D, unlocking PCIe 5.0 for next-gen GPUs (e.g., RTX 5090) and SSDs—no costly swaps needed.
Intel LGA 1700: Short-Term Power:
Intel’s 14th Gen CPUs deliver brute force today but dead-end in 2025. Upgrading to 15th Gen Arrow Lake means buying a new LGA 1851 motherboard, DDR5 RAM, and cooler—a $300+ investment.
Key Takeaways:
- AM5:
- Backward-compatible cooling (AM4 coolers work).
- Full PCIe 5.0 lanes for GPUs and storage (no bandwidth splitting).
- Budget builders can reuse existing parts, as detailed in our Ryzen 5600 vs 5600X In 2025 guide.
- LGA 1700:
- DDR4 support locks users into outdated memory for future builds.
- Limited to PCIe 5.0 for GPUs only; adding a Gen5 SSD halves GPU lanes.
