Not in a simple one-size-fits-all way. Xeon E3-1245 v6 makes more sense for workstation-style multi-core throughput, while Ryzen 7 3700X is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

Which one is better for gaming?

If gaming is the priority, Ryzen 7 3700X is the better pick here. According to our tests, it delivers 132.0% more average FPS across 4 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Ryzen 7 3700X is the better fit. You are getting 157.5% better PassMark, backed by 8 cores and 16 threads. It also carries the larger cache pool with 300% larger total L3 cache (32 MB vs 8 MB).

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

Ryzen 7 3700X is the smarter buy today. Ryzen 7 3700X is at an unclear MSRP at $329 MSRP versus unclear MSRP, and it gives you a 132.0% average FPS lead across 4 shared CPU game tests in our data. It is also 100.0% better value on MSRP (68.2 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.

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

Ryzen 7 3700X is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2017), 300% larger total L3 cache (32 MB vs 8 MB), and more multi-core headroom with 8 cores / 16 threads instead of 4/8. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.
