Quick Answers

So, is Core i7-10810U better than Xeon E3-1585L v5?

Not really, because they are built for different jobs. Xeon E3-1585L v5 makes more sense for workstation-style multi-core throughput, while Core i7-10810U 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 i7-10810U is the better pick. According to our tests, it delivers 25.7% 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 i7-10810U is the stronger fit. You are getting 0.4% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

Core i7-10810U still makes the most sense overall. Core i7-10810U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 25.7% average FPS lead across 50 shared CPU game tests in our data.

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

Core i7-10810U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2016), 50% larger total L3 cache (12 MB vs 8 MB), and more multi-core headroom with 6 cores / 12 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
