2017

Why buy it

✅+1.1% higher PassMark.
✅+166.7% larger total L3 cache (64 MB vs 24 MB).
✅Better for workstations and heavier parallel workloads: 24 cores / 48 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-13800H across 50 shared CPU benchmark tests.
❌300% higher power demand at 180W vs 45W.
❌Older platform position on TR4 with DDR4, while Core i7-13800H moves to FCBGA1744 and DDR5.

Quick Answers

So, is Core i7-13800H better than EPYC 7451?

Not really, because they are built for different jobs. EPYC 7451 makes more sense for workstation-style multi-core throughput, while Core i7-13800H 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, EPYC 7451 is the stronger fit. You are getting 1.1% better PassMark, backed by 24 cores and 48 threads. It also has the larger cache pool with 166.7% larger total L3 cache (64 MB vs 24 MB).

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

Core i7-13800H still makes the most sense overall. Core i7-13800H comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 8.6% average FPS lead across 50 shared CPU game tests in our data.

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

Core i7-13800H makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2017) and a healthier platform with FCBGA1744 and DDR5 instead of TR4. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
