Quick Answers

So, is Xeon E5-1660 better than Core i3-N300?

Not really, because they are built for different jobs. Xeon E5-1660 makes more sense for workstation-style multi-core throughput, while Core i3-N300 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon E5-1660 is the better pick. According to our tests, it delivers 4.2% 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 E5-1660 is the stronger fit. You are getting 0.5% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 150% larger total L3 cache (15 MB vs 6 MB).

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

Xeon E5-1660 is the easy recommendation for a fresh desktop build. Xeon E5-1660 comes in 249.5% more expensive on MSRP at $1,080 MSRP versus $309 MSRP, and it still gives you a 4.2% average FPS lead across 50 shared CPU game tests in our data. Core i3-N300 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 4.2% in the shared gaming data.

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

Core i3-N300 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2012) and a healthier platform with FCBGA1264 and DDR5 instead of LGA2011. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
