Quick Answers

So, is M1 Pro 8-Core better than Core i7-7820X?

It depends on what you want from the system. For gaming, Core i7-7820X is ahead with a 21.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, M1 Pro 8-Core pulls ahead with 0.3% better PassMark. M1 Pro 8-Core also has the bigger cache pool with 45.5% larger total L3 cache (16 MB vs 11 MB).

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

For streaming, content creation, and heavier multitasking, M1 Pro 8-Core is the stronger fit. You are getting 0.3% better PassMark, backed by 8 cores and 8 threads. It also has the larger cache pool with 45.5% larger total L3 cache (16 MB vs 11 MB).

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

M1 Pro 8-Core is still the much better call for a fresh build. M1 Pro 8-Core comes in at an unclear MSRP at unclear MSRP versus $599 MSRP, and it still gives you 0.3% better PassMark. Core i7-7820X only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (28.7 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA2066.

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

M1 Pro 8-Core makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2017), a healthier platform with none and DDR5 instead of LGA2066, 45.5% larger total L3 cache (16 MB vs 11 MB), and more multi-core headroom with 8 cores / 8 threads instead of 8/16. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
