Quick Answers

So, is Xeon E3-1235L v5 better than Phenom II X6 1055T (95W)?

Not really, because they are built for different jobs. Xeon E3-1235L v5 makes more sense for workstation-style multi-core throughput, while Phenom II X6 1055T (95W) 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 E3-1235L v5 is the stronger fit. You are getting 1% better PassMark, backed by 4 cores and 4 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 E3-1235L v5 still makes the most sense overall. Xeon E3-1235L v5 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 1% better PassMark.

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

Xeon E3-1235L v5 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2010), 33.3% larger total L3 cache (8 MB vs 6 MB), and more multi-core headroom with 4 cores / 4 threads instead of 6/6. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
