Quick Answers

So, is Ryzen 7 3700X better than Xeon E3-1240?
Not in a simple one-size-fits-all way. Xeon E3-1240 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 242.6% more average FPS across 5 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 318.4% 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 20.5% more expensive on MSRP at $329 MSRP versus $273 MSRP, and it gives you a 242.6% average FPS lead across 5 shared CPU game tests in our data. It is also 247.2% better value on MSRP (68.2 vs 19.6 PassMark/$), 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 2011), 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.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
