Ryzen 5 8640U

2023

Why buy it

✅Better for gaming: +12.7% higher average FPS across 50 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 50 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.

Quick Answers

So, is Ryzen 5 8640U better than Xeon E5-4667 v4?

Not really, because they are built for different jobs. Xeon E5-4667 v4 makes more sense for workstation-style multi-core throughput, while Ryzen 5 8640U is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon E5-4667 v4 is the stronger fit. You are getting 0.2% better PassMark, backed by 18 cores and 36 threads. It also has the larger cache pool with 181.3% larger total L3 cache (45 MB vs 16 MB).

Which one is the smarter buy today, not just the cheaper CPU?

Ryzen 5 8640U still makes the most sense overall. Ryzen 5 8640U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 12.7% average FPS lead across 50 shared CPU game tests in our data.

Which one is more future-proof for 2026 and beyond?

Ryzen 5 8640U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2016), a healthier platform with FP8 and DDR5 instead of LGA2011, and AVX-512 support for heavier modern compute workloads. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
