Ryzen 5 8645HS

2023

Why buy it

✅Better for gaming: +13.4% higher average FPS across 48 shared CPU benchmark tests.
✅Draws 45W instead of 140W, a 95W reduction.
✅Newer platform on FP8 with DDR5 support instead of SP3r2 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon 760M, while Ryzen Threadripper 1920 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (16 MB vs 32 MB).
❌Less compelling for workstation-style loads than Ryzen Threadripper 1920, which brings 12 cores / 24 threads.

Ryzen Threadripper 1920

2017

Why buy it

✅+100% larger total L3 cache (32 MB vs 16 MB).
✅Better for workstations and heavier parallel workloads: 12 cores / 24 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Ryzen 5 8645HS across 48 shared CPU benchmark tests.
❌Lower PassMark (22,066 vs 22,257).
❌Launch MSRP is still $799 MSRP, while Ryzen 5 8645HS mostly shows up through inconsistent older-market listings.
❌211.1% higher power demand at 140W vs 45W.
❌Older platform position on SP3r2 with DDR4, while Ryzen 5 8645HS moves to FP8 and DDR5.

Quick Answers

So, is Ryzen 5 8645HS better than Ryzen Threadripper 1920?

Not in a simple one-size-fits-all way. Ryzen Threadripper 1920 makes more sense for workstation-style multi-core throughput, while Ryzen 5 8645HS 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, Ryzen 5 8645HS is the better pick here. According to our tests, it delivers 13.4% more average FPS across 48 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Ryzen 5 8645HS is the better fit. You are getting 0.9% better PassMark, backed by 6 cores and 12 threads.

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

Ryzen 5 8645HS is still the faster CPU overall, but Ryzen Threadripper 1920 makes more sense if price matters more than absolute performance. Ryzen 5 8645HS is at an unclear MSRP at unclear MSRP versus $799 MSRP, and it gives you a 13.4% average FPS lead across 48 shared CPU game tests in our data. Ryzen Threadripper 1920 is also 100.0% better value on MSRP (27.6 vs 0.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.

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

Ryzen 5 8645HS is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2017), a healthier platform with FP8 and DDR5 instead of SP3r2, more multi-core headroom with 6 cores / 12 threads instead of 12/24, 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.

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.
