Quick Answers

So, is Xeon E3-1545M v5 better than Core i7-5775R?

Not really, because they are built for different jobs. Xeon E3-1545M v5 makes more sense for workstation-style multi-core throughput, while Core i7-5775R is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Xeon E3-1545M v5 is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Xeon E3-1545M v5 is the better buy right now. Xeon E3-1545M v5 comes in at an unclear MSRP at $581 MSRP versus unclear MSRP, and it still gives you 0.6% better PassMark. The compromise is that Core i7-5775R is still the better pure gaming CPU with a 4.0% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (13.1 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Xeon E3-1545M v5 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2015), 33.3% larger total L3 cache (8 MB vs 6 MB), and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
