Quick Answers

So, is PRO A10-8750B better than Xeon X5550?

Not really, because they are built for different jobs. Xeon X5550 makes more sense for workstation-style multi-core throughput, while PRO A10-8750B is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, PRO A10-8750B is the better pick. According to our tests, it delivers 1.4% 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, PRO A10-8750B is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 4 threads.

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

PRO A10-8750B still makes the most sense overall. PRO A10-8750B comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 1.4% average FPS lead across 50 shared CPU game tests in our data.

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

PRO A10-8750B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2009) and more multi-core headroom with 4 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
