❌Launch MSRP is still $378 MSRP, while Xeon E5-4607 mostly shows up through inconsistent older-market listings.

Xeon E5-4607

2012

Why buy it

✅+87.5% larger total L3 cache (15 MB vs 8 MB).
✅Better for workstations and heavier parallel workloads: 6 cores / 12 threads.

Trade-offs

❌Lower PassMark (6,986 vs 7,012).
❌111.1% higher power demand at 95W vs 45W.

Quick Answers

So, is Core i7-6820HK better than Xeon E5-4607?

Not really, because they are built for different jobs. Xeon E5-4607 makes more sense for workstation-style multi-core throughput, while Core i7-6820HK is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i7-6820HK is the better pick. According to our tests, it delivers 1.1% 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, Core i7-6820HK is the stronger fit. You are getting 0.4% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-6820HK is the better buy right now. Core i7-6820HK comes in at an unclear MSRP at $378 MSRP versus unclear MSRP, and it still gives you a 1.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (18.6 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i7-6820HK makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2012) and more multi-core headroom with 4 cores / 8 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
