Ryzen 7 3700U vs Xeon E5-4640: Pros, Cons & Final Verdict

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

Ryzen 7 3700U

2019

Why buy it

✅Draws 15W instead of 95W, a 80W reduction.
✅100+% more PCIe lanes (12 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon RX Vega 10, while Xeon E5-4640 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (4 MB vs 20 MB).
❌Less compelling for workstation-style loads than Xeon E5-4640, which brings 8 cores / 16 threads.

Xeon E5-4640

2012

Why buy it

✅+400% larger total L3 cache (20 MB vs 4 MB).
✅Better for workstations and heavier parallel workloads: 8 cores / 16 threads.

Trade-offs

❌Lower PassMark (7,012 vs 7,049).
❌Launch MSRP is still $2,725 MSRP, while Ryzen 7 3700U mostly shows up through inconsistent older-market listings.
❌533.3% higher power demand at 95W vs 15W.
❌No integrated graphics, while Ryzen 7 3700U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Ryzen 7 3700U better than Xeon E5-4640?

Not really, because they are built for different jobs. Xeon E5-4640 makes more sense for workstation-style multi-core throughput, while Ryzen 7 3700U is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Ryzen 7 3700U is the better pick. According to our tests, it delivers 2.3% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Ryzen 7 3700U is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 8 threads.

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

Ryzen 7 3700U is still the faster CPU overall, but Xeon E5-4640 is easier to justify if budget matters more than peak performance. Ryzen 7 3700U comes in at an unclear MSRP at unclear MSRP versus $2,725 MSRP, and it still gives you a 2.3% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-4640 is also 100.0% better value on MSRP (2.6 vs 0.0 PassMark/$), 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 7 3700U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2012) and more multi-core headroom with 4 cores / 8 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
