Pentium G4600

2017

Why buy it

✅+0.2% higher PassMark.
✅Draws 51W instead of 80W, a 29W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E5620 across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (3 MB vs 12 MB).
❌Less compelling for workstation-style loads than Xeon E5620, which brings 4 cores / 8 threads.
❌Launch MSRP is still $82 MSRP, while Xeon E5620 mostly shows up through inconsistent older-market listings.

Xeon E5620

2010

Why buy it

✅Better for gaming: +9.6% higher average FPS across 50 shared CPU benchmark tests.
✅+300% larger total L3 cache (12 MB vs 3 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 8 threads.

Trade-offs

❌Lower PassMark (3,621 vs 3,629).
❌56.9% higher power demand at 80W vs 51W.

Quick Answers

So, is Pentium G4600 better than Xeon E5620?

Not really, because they are built for different jobs. Xeon E5620 makes more sense for workstation-style multi-core throughput, while Pentium G4600 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, Pentium G4600 is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 4 threads.

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

Pentium G4600 is the better buy right now. Pentium G4600 comes in at an unclear MSRP at $82 MSRP versus unclear MSRP, and it still gives you 0.2% better PassMark. The compromise is that Xeon E5620 is still the better pure gaming CPU with a 9.6% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (44.3 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium G4600 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2010) and more multi-core headroom with 2 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
