Quick Answers

So, is Core i5-1145G7 better than Xeon E5-2620 v4?

Not really, because they are built for different jobs. Xeon E5-2620 v4 makes more sense for workstation-style multi-core throughput, while Core i5-1145G7 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, Core i5-1145G7 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads.

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

Core i5-1145G7 is still the faster CPU overall, but Xeon E5-2620 v4 is easier to justify if budget matters more than peak performance. Core i5-1145G7 comes in at an unclear MSRP at unclear MSRP versus $417 MSRP, and it still gives you 0.1% better PassMark. The compromise is that Xeon E5-2620 v4 is still the better pure gaming CPU with a 6.5% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-2620 v4 is also 100.0% better value on MSRP (22.2 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i5-1145G7 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2016), more multi-core headroom with 4 cores / 8 threads instead of 8/16, and AVX-512 support for heavier modern compute workloads. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
