❌Lower PassMark (2,682 vs 2,709).
❌Smaller total L3 cache (2 MB vs 3 MB).
❌Launch MSRP is still $50 MSRP, while Core i5-5300U mostly shows up through inconsistent older-market listings.

Core i5-5300U

2015

Why buy it

✅+1% higher PassMark.
✅+50% larger total L3 cache (3 MB vs 2 MB).

Trade-offs

❌782.8% higher power demand at 512W vs 58W.
❌No integrated graphics, while Celeron G5900 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron G5900 better than Core i5-5300U?

It depends on what you want from the system. For gaming, Celeron G5900 is ahead with a 0.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-5300U pulls ahead with 1% better PassMark. Core i5-5300U also has the bigger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-5300U is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 4 threads. It also has the larger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

Celeron G5900 is the better buy right now. Celeron G5900 comes in at an unclear MSRP at $50 MSRP versus unclear MSRP, and it still gives you a 0.3% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-5300U is still stronger for heavier multi-core work with 1% better PassMark. It is also 100.0% better value on MSRP (53.6 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Celeron G5900 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2015). That makes it the safer long-term bet.
