Core i3-1305U

2023

Why buy it

✅Better for gaming: +4.9% higher average FPS across 50 shared CPU benchmark tests.
✅+25% larger total L3 cache (10 MB vs 8 MB).
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics, while Processor U300 needs a discrete GPU.

Trade-offs

❌Lower PassMark (8,634 vs 8,897).

Processor U300

2023

Why buy it

✅+3% higher PassMark.

Trade-offs

❌Worse for gaming: lower average FPS than Core i3-1305U across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (8 MB vs 10 MB).
❌Launch MSRP is still $193 MSRP, while Core i3-1305U mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while Core i3-1305U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Processor U300 better than Core i3-1305U?

It depends on what you want from the system. For gaming, Core i3-1305U is ahead with a 4.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Processor U300 pulls ahead with 3% better PassMark. Core i3-1305U also has the bigger cache pool with 25% larger total L3 cache (10 MB vs 8 MB).

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

For streaming, content creation, and heavier multitasking, Processor U300 is the stronger fit. You are getting 3% better PassMark, backed by 5 cores and 6 threads.

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

Processor U300 is the better buy right now. Processor U300 comes in at an unclear MSRP at $193 MSRP versus unclear MSRP, and it still gives you 3% better PassMark. The compromise is that Core i3-1305U is still the better pure gaming CPU with a 4.9% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (46.1 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Processor U300 makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 5 cores / 6 threads instead of 5/6. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
