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 i7-9700K

2018

Why buy it

  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 630, while Ryzen 5 PRO 8645HS needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Ryzen 5 PRO 8645HS across 24 shared CPU benchmark tests.
  • Lower PassMark (14,397 vs 23,227).
  • Smaller total L3 cache (12 MB vs 16 MB).
  • Launch MSRP is still $385 MSRP, while Ryzen 5 PRO 8645HS mostly shows up through inconsistent older-market listings.
  • 111.1% higher power demand at 95W vs 45W.

Ryzen 5 PRO 8645HS

2024

Why buy it

  • Better for gaming: +12.5% higher average FPS across 24 shared CPU benchmark tests.
  • +33.3% larger total L3 cache (16 MB vs 12 MB).
  • Draws 45W instead of 95W, a 50W reduction.
  • Newer platform on FP7 with DDR5 support instead of LGA1151 and DDR4.

Trade-offs

  • No integrated graphics, while Core i7-9700K can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Ryzen 5 PRO 8645HS better than Core i7-9700K?
Yes. Ryzen 5 PRO 8645HS is the better overall CPU here. You are getting a 12.5% average FPS lead across 24 shared CPU game tests in our data, 61.3% better PassMark, and the stronger long-term platform, which makes it the stronger all-around choice.
Which one is better for gaming?
If gaming is the priority, Ryzen 5 PRO 8645HS is the better pick here. According to our tests, it delivers 12.5% more average FPS across 24 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Ryzen 5 PRO 8645HS is the better fit. You are getting 61.3% better PassMark, backed by 6 cores and 12 threads. It also carries the larger cache pool with 33.3% larger total L3 cache (16 MB vs 12 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 5 PRO 8645HS is the smarter buy by a wide margin for a fresh build. Ryzen 5 PRO 8645HS is at an unclear MSRP at unclear MSRP versus $385 MSRP, and it gives you a 12.5% average FPS lead across 24 shared CPU game tests in our data. Core i7-9700K only looks stronger on raw value math because it is extremely cheap, but that is mostly used-market pricing on an obsolete 2018 platform. Even with 100.0% better value on paper (37.4 vs 0.0 PassMark/$), it really only makes sense as a very cheap stopgap or a niche existing-platform option for someone already on LGA1151.
Which one is more future-proof for 2026 and beyond?
Ryzen 5 PRO 8645HS is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2018), a healthier platform with FP7 and DDR5 instead of LGA1151, 33.3% larger total L3 cache (16 MB vs 12 MB), and more multi-core headroom with 6 cores / 12 threads instead of 8/8. 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.
