See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Ryzen 5 PRO 8640U

2024

Why buy it

✅Better for gaming: +19.8% higher average FPS across 50 shared CPU benchmark tests.
✅Draws 28W instead of 105W, a 77W reduction.
✅Newer platform on FP7 with DDR5 support instead of LGA2011 and DDR4.

Trade-offs

❌Lower PassMark (22,373 vs 22,559).
❌Smaller total L3 cache (16 MB vs 30 MB).
❌Less compelling for workstation-style loads than Xeon E5-4640 v4, which brings 12 cores / 24 threads and 40 PCIe lanes.

Xeon E5-4640 v4

2016

Why buy it

✅+0.8% higher PassMark.
✅+87.5% larger total L3 cache (30 MB vs 16 MB).
✅Better for workstations and heavier parallel workloads: 12 cores / 24 threads, plus 40 PCIe lanes vs 0.
✅100+% more PCIe lanes (40 vs 0) for storage and expansion-heavy builds.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 5 PRO 8640U across 50 shared CPU benchmark tests.
❌Launch MSRP is still $2,837 MSRP, while Ryzen 5 PRO 8640U mostly shows up through inconsistent older-market listings.
❌275% higher power demand at 105W vs 28W.
❌Older platform position on LGA2011 with DDR4, while Ryzen 5 PRO 8640U moves to FP7 and DDR5.

Quick Answers

So, is Ryzen 5 PRO 8640U better than Xeon E5-4640 v4?

Not really, because they are built for different jobs. Xeon E5-4640 v4 makes more sense for workstation-style multi-core throughput, while Ryzen 5 PRO 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 E5-4640 v4 is the stronger fit. You are getting 0.8% better PassMark, backed by 12 cores and 24 threads. It also has the larger cache pool with 87.5% larger total L3 cache (30 MB vs 16 MB).

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

Ryzen 5 PRO 8640U is still the faster CPU overall, but Xeon E5-4640 v4 is easier to justify if budget matters more than peak performance. Ryzen 5 PRO 8640U comes in at an unclear MSRP at unclear MSRP versus $2,837 MSRP, and it still gives you a 19.8% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon E5-4640 v4 is still stronger for heavier multi-core work with 0.8% better PassMark. Xeon E5-4640 v4 is also 100.0% better value on MSRP (8.0 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Ryzen 5 PRO 8640U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2016) and a healthier platform with FP7 and DDR5 instead of LGA2011. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
