Ryzen 7 5800X

2020

Why buy it

✅Costs $3,541 less on MSRP ($449 MSRP vs $3,990 MSRP).
✅Delivers 208.3% more PassMark for each dollar spent, at 61.7 vs 20.0 PassMark/$ ($449 MSRP vs $3,990 MSRP).
✅Draws 105W instead of 280W, a 175W reduction.

Trade-offs

❌No 3D V-Cache or similar L3 advantage, which matters in CPU-limited gaming (32 MB vs 256 MB).
❌Lower PassMark (27,712 vs 79,889).
❌Less compelling for workstation-style loads than Ryzen Threadripper 3990X, which brings 64 cores / 128 threads and 88 PCIe lanes.

Ryzen Threadripper 3990X

2019

Why buy it

✅Massive L3 cache advantage with 256 MB vs 32 MB, which is a real win in CPU-limited gaming.
