Core i3-9300 vs Core i7-7820HQ: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Core i3-9300

2019

Why buy it

  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 630, while Core i7-7820HQ needs a discrete GPU.
  • Includes a boxed cooler (Yes), unlike Core i7-7820HQ.

Trade-offs

  • Lower PassMark (7,105 vs 7,184).
  • Smaller total L3 cache (6 MB vs 8 MB).
  • Launch MSRP is still $143 MSRP, while Core i7-7820HQ mostly shows up through inconsistent older-market listings.
  • 37.8% higher power demand at 62W vs 45W.

Core i7-7820HQ

2017

Why buy it

  • +1.1% higher PassMark.
  • +33.3% larger total L3 cache (8 MB vs 6 MB).
  • Draws 45W instead of 62W, a 17W reduction.

Trade-offs

  • No integrated graphics, while Core i3-9300 can still boot and troubleshoot without a discrete GPU.
  • No boxed cooler included, unlike Core i3-9300.

Quick Answers

So, is Core i3-9300 better than Core i7-7820HQ?
It depends on what you want from the system. For gaming, Core i3-9300 is ahead with a 0.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-7820HQ pulls ahead with 1.1% better PassMark. Core i7-7820HQ also has the bigger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i7-7820HQ is the stronger fit. You are getting 1.1% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i3-9300 is the better buy right now. Core i3-9300 comes in at an unclear MSRP at $143 MSRP versus unclear MSRP, and it still gives you a 0.9% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i7-7820HQ is still stronger for heavier multi-core work with 1.1% better PassMark. It is also 100.0% better value on MSRP (49.7 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core i3-9300 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2017). That makes it the safer long-term bet.
