Celeron B815 vs Pentium G3440T: Pros, Cons & Final Verdict

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

Celeron B815

2012

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics (Sandy Bridge), while Pentium G3440T needs a discrete GPU.

Trade-offs

❌Lower PassMark (2,093 vs 2,107).
❌Smaller total L3 cache (2 MB vs 3 MB).
❌Launch MSRP is still $86 MSRP, while Pentium G3440T mostly shows up through inconsistent older-market listings.

Pentium G3440T

2014

Why buy it

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

Trade-offs

❌No integrated graphics, while Celeron B815 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Pentium G3440T better than Celeron B815?

Yes. Pentium G3440T is the better all-around CPU here. It gives you a 1.9% average FPS lead across 50 shared CPU game tests in our data, 0.7% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium G3440T is the better pick. According to our tests, it delivers 1.9% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Pentium G3440T is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 2 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?

Pentium G3440T is still the much better call for a fresh build. Pentium G3440T comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you a 1.9% average FPS lead across 50 shared CPU game tests in our data. Celeron B815 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (24.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA988.

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

Pentium G3440T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012), 50% larger total L3 cache (3 MB vs 2 MB), and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
