✅Integrated graphics onboard with Intel UHD Graphics 600, while Pentium G4520 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Pentium G4520 across 50 shared CPU benchmark tests.

Pentium G4520

2015

Why buy it

✅Better for gaming: +5.4% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

❌Lower PassMark (2,670 vs 2,688).
❌Launch MSRP is still $86 MSRP, while Celeron J4115 mostly shows up through inconsistent older-market listings.
❌1175% higher power demand at 51W vs 4W.
❌No integrated graphics, while Celeron J4115 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron J4115 better than Pentium G4520?

It depends on what you want from the system. For gaming, Pentium G4520 is ahead with a 5.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron J4115 pulls ahead with 0.7% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron J4115 is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 4 threads.

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

Celeron J4115 is still the much better call for a fresh build. Celeron J4115 comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you 0.7% better PassMark. Pentium G4520 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (31.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Celeron J4115 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2015) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
