M1 Pro 8-Core vs Xeon E-2378: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

M1 Pro 8-Core

2021

Why buy it

✅+0.9% higher PassMark.
✅Draws 28W instead of 65W, a 37W reduction.
✅Newer platform on none with DDR5 support instead of LGA1200 and DDR4.
✅Integrated graphics onboard with Apple M1 Pro GPU (14-core), while Xeon E-2378 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E-2378 across 50 shared CPU benchmark tests.
❌Less compelling for workstation-style loads than Xeon E-2378, which brings 8 cores / 16 threads and 20 PCIe lanes.
❌No AVX-512 support for niche heavy compute workloads where it can matter.

Xeon E-2378

2021

Why buy it

✅Better for gaming: +26.1% higher average FPS across 50 shared CPU benchmark tests.
✅Better for workstations and heavier parallel workloads: 8 cores / 16 threads, plus 20 PCIe lanes vs 0.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.

Trade-offs

❌Lower PassMark (17,069 vs 17,218).
❌Launch MSRP is still $362 MSRP, while M1 Pro 8-Core mostly shows up through inconsistent older-market listings.
❌132.1% higher power demand at 65W vs 28W.
❌Older platform position on LGA1200 with DDR4, while M1 Pro 8-Core moves to none and DDR5.
❌No integrated graphics, while M1 Pro 8-Core can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is M1 Pro 8-Core better than Xeon E-2378?

Not really, because they are built for different jobs. Xeon E-2378 makes more sense for workstation-style multi-core throughput, while M1 Pro 8-Core 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, M1 Pro 8-Core is the stronger fit. You are getting 0.9% better PassMark, backed by 8 cores and 8 threads.

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

M1 Pro 8-Core is still the faster CPU overall, but Xeon E-2378 is easier to justify if budget matters more than peak performance. M1 Pro 8-Core comes in at an unclear MSRP at unclear MSRP versus $362 MSRP, and it still gives you 0.9% better PassMark. The compromise is that Xeon E-2378 is still the better pure gaming CPU with a 26.1% average FPS lead across 50 shared CPU game tests in our data. Xeon E-2378 is also 100.0% better value on MSRP (47.2 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

M1 Pro 8-Core makes more sense long term for 2026 and beyond. You are getting a healthier platform with none and DDR5 instead of LGA1200 and more multi-core headroom with 8 cores / 8 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
