Quick Answers

So, is Xeon E5-2663 V3 better than Xeon 6315P?

Yes. Xeon E5-2663 V3 is the better all-around CPU here. It gives you a 18.1% average FPS lead across 50 shared CPU game tests in our data and 0.5% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Xeon E5-2663 V3 is the better pick. According to our tests, it delivers 18.1% 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, Xeon E5-2663 V3 is the stronger fit. You are getting 0.5% better PassMark, backed by 10 cores and 20 threads. It also has the larger cache pool with 108.3% larger total L3 cache (25 MB vs 12 MB).

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

Xeon E5-2663 V3 is still the faster CPU overall, but Xeon 6315P is easier to justify if budget matters more than peak performance. Xeon E5-2663 V3 comes in at an unclear MSRP at unclear MSRP versus $1,166 MSRP, and it still gives you a 18.1% average FPS lead across 50 shared CPU game tests in our data. Xeon 6315P is also 100.0% better value on MSRP (10.1 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Xeon 6315P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2014) and a healthier platform with LGA1700 and DDR5 instead of LGA2011-3. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
