Ryzen 5 8640U

2023

Why buy it

✅Better for gaming: +14.4% higher average FPS across 4 shared CPU benchmark tests.
✅Draws 28W instead of 135W, a 107W reduction.
✅Newer platform on FP8 with DDR5 support instead of LGA2011 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon 760M, while Xeon E5-4667 v4 needs a discrete GPU.

Trade-offs

❌Lower PassMark (20,274 vs 20,319).
❌Smaller total L3 cache (16 MB vs 45 MB).
❌Less compelling for workstation-style loads than Xeon E5-4667 v4, which brings 18 cores / 36 threads.

Xeon E5-4667 v4

2016

Why buy it

✅+0.2% higher PassMark.
✅+181.3% larger total L3 cache (45 MB vs 16 MB).
✅Better for workstations and heavier parallel workloads: 18 cores / 36 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 5 8640U across 4 shared CPU benchmark tests.
❌382.1% higher power demand at 135W vs 28W.
❌Older platform position on LGA2011 with DDR4, while Ryzen 5 8640U moves to FP8 and DDR5.
❌No integrated graphics, while Ryzen 5 8640U can still boot and troubleshoot without a discrete GPU.
