About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, productivity performance, platform differences, power efficiency, pricing context, and upgrade path so you can see which CPU actually makes more sense.

Core i7-12700K

2021

Why buy it

  • Costs $2,589 less on MSRP ($409 MSRP vs $2,998 MSRP).
  • Delivers 158.9% more PassMark for each dollar spent, at 84.0 vs 32.4 PassMark/$ ($409 MSRP vs $2,998 MSRP).
  • Draws 125W instead of 280W, a 155W reduction.
  • Integrated graphics onboard with Intel UHD Graphics 770, while EPYC 9355P needs a discrete GPU.

Trade-offs

  • No 3D V-Cache or similar L3 advantage, which matters in CPU-limited gaming (25 MB vs 256 MB).
  • Lower PassMark (34,347 vs 97,249).
  • Less compelling for workstation-style loads than EPYC 9355P, which brings 32 cores / 64 threads and 128 PCIe lanes.

Quick Answers

So, is EPYC 9355P better than Core i7-12700K?
Not in a simple one-size-fits-all way. EPYC 9355P makes more sense for workstation-style multi-core throughput, while Core i7-12700K is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.
Which one is better for gaming?
If gaming is the priority, EPYC 9355P is the better pick here. According to our tests, it delivers 1.6% more average FPS across 4 shared CPU game tests. It also has a big cache advantage at 256 MB vs 25 MB.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, EPYC 9355P is the better fit. You are getting 183.1% better PassMark, backed by 32 cores and 64 threads. It also carries the larger cache pool with 924% larger total L3 cache (256 MB vs 25 MB).
Which one is the smarter buy today, not just the cheaper CPU?
EPYC 9355P is still the faster CPU overall, but Core i7-12700K makes more sense if price matters more than absolute performance. EPYC 9355P is 633.0% more expensive on MSRP at $2,998 MSRP versus $409 MSRP, and it gives you a 1.6% average FPS lead across 4 shared CPU game tests in our data. Core i7-12700K is also 158.9% better value on MSRP (84.0 vs 32.4 PassMark/$), 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 9355P is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2021), 3D V-Cache and a much larger 256 MB L3 cache instead of 25 MB, and more multi-core headroom with 32 cores / 64 threads instead of 12/20. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
