Quick Answers

So, is EPYC 4484PX better than Core Ultra 7 255HX?

Not in a simple one-size-fits-all way. EPYC 4484PX makes more sense for workstation-style multi-core throughput, while Core Ultra 7 255HX 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 4484PX is the better pick here. According to our tests, it delivers 18.6% more average FPS across 50 shared CPU game tests. It also has a big cache advantage at 128 MB vs 30 MB.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, EPYC 4484PX is the better fit. You are getting 3.6% better Geekbench multi-core, backed by 12 cores and 24 threads. It also carries the larger cache pool with 326.7% larger total L3 cache (128 MB vs 30 MB).

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

EPYC 4484PX is the smarter buy today. EPYC 4484PX is at an unclear MSRP at $599 MSRP versus unclear MSRP, and it gives you a 18.6% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (84.4 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.

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

EPYC 4484PX is the more future-proof choice for 2026 and beyond. You are getting 3D V-Cache and a much larger 128 MB L3 cache instead of 30 MB, more multi-core headroom with 12 cores / 24 threads instead of 20/20, and AVX-512 support for heavier modern compute workloads. That extra cache should hold up really well in CPU-limited games and high-refresh builds.

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.
