Quick Answers

So, is Xeon E-2246G better than Xeon D-1587?

Yes. Xeon E-2246G is the better all-around CPU here. It gives you a 10.6% average FPS lead across 50 shared CPU game tests in our data, 1.5% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Xeon E-2246G is the better pick. According to our tests, it delivers 10.6% 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 E-2246G is the stronger fit. You are getting 1.5% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 700% larger total L3 cache (12 MB vs 1.5 MB).

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

Xeon E-2246G is the better buy right now. Xeon E-2246G comes in $1,341 cheaper on MSRP at $311 MSRP versus $1,652 MSRP, and it still gives you a 10.6% average FPS lead across 50 shared CPU game tests in our data. It is also 439.1% better value on MSRP (44.5 vs 8.3 PassMark/$), 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 E-2246G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2016), 700% larger total L3 cache (12 MB vs 1.5 MB), and more multi-core headroom with 6 cores / 12 threads instead of 16/32. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
