Quick Answers

So, is Xeon E5-2640 better than Xeon D-1622?

Yes. Xeon E5-2640 is the better all-around CPU here. It gives you a 11.5% average FPS lead across 50 shared CPU game tests in our data and 1.6% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Xeon E5-2640 is the better pick. According to our tests, it delivers 11.5% 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 E5-2640 is the stronger fit. You are getting 1.6% 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 E5-2640 is the easy recommendation for a fresh desktop build. Xeon E5-2640 comes in 353.8% more expensive on MSRP at $885 MSRP versus $195 MSRP, and it still gives you a 11.5% average FPS lead across 50 shared CPU game tests in our data. Xeon D-1622 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 11.5% in the shared gaming data.

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

Xeon D-1622 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2012). That makes it the safer long-term bet.
