Which one is the smarter buy today, not just the cheaper CPU?
EPYC 9135 is still the faster CPU overall, but Core i7-12700K makes more sense if price matters more than absolute performance. EPYC 9135 is 196.8% more expensive on MSRP at $1,214 MSRP versus $409 MSRP, and it gives you 68.3% better PassMark. The trade-off is that Core i7-12700K is still the better pure gaming CPU with a 13.2% average FPS lead across 50 shared CPU game tests in our data. Core i7-12700K is also 76.4% better value on MSRP (84.0 vs 47.6 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.
Which one is more future-proof for 2026 and beyond?
EPYC 9135 is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2021), 156% larger total L3 cache (64 MB vs 25 MB), more multi-core headroom with 16 cores / 32 threads instead of 12/20, and AVX-512 support for heavier modern compute workloads. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.
