2019

Why buy it

✅Draws 15W instead of 105W, a 90W reduction.
✅Integrated graphics onboard with Radeon Vega 8, while Ryzen 7 5800X needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 7 5800X across 4 shared CPU benchmark tests.
❌Lower PassMark (6,836 vs 27,712).
❌Smaller total L3 cache (4 MB vs 32 MB).

Ryzen 7 5800X

2020

Why buy it

✅Better for gaming: +225.1% higher average FPS across 4 shared CPU benchmark tests.
✅+700% larger total L3 cache (32 MB vs 4 MB).
✅100% more PCIe lanes (24 vs 12) for storage and expansion-heavy builds.

Trade-offs

❌Launch MSRP is still $449 MSRP, while Ryzen 5 3500U mostly shows up through inconsistent older-market listings.
❌600% higher power demand at 105W vs 15W.
❌No integrated graphics, while Ryzen 5 3500U can still boot and troubleshoot without a discrete GPU.
