Celeron G540T

2011

Why buy it

✅Costs $22 less on MSRP ($42 MSRP vs $64 MSRP).
✅Delivers 52.1% more PassMark for each dollar spent, at 27.1 vs 17.8 PassMark/$ ($42 MSRP vs $64 MSRP).
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Sandy Bridge), while Pentium G640T needs a discrete GPU.

Trade-offs

❌Lower PassMark (1,137 vs 1,139).
❌Smaller total L3 cache (2 MB vs 3 MB).

Pentium G640T

2012

Why buy it

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

Trade-offs

❌Lower PassMark per dollar, at 17.8 vs 27.1 PassMark/$ ($64 MSRP vs $42 MSRP).
❌No integrated graphics, while Celeron G540T can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Pentium G640T better than Celeron G540T?

Yes. Pentium G640T is the better all-around CPU here. It gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data, 0.2% 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 G640T is the better pick. According to our tests, it delivers 0.1% 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 G640T is the stronger fit. You are getting 0.2% 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 G640T is still the much better call for a fresh build. Pentium G640T comes in 52.4% more expensive on MSRP at $64 MSRP versus $42 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. Celeron G540T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 52.1% better value on paper (27.1 vs 17.8 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.

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

Pentium G640T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2011), 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.
