✅Draws 4W instead of 35W, a 31W reduction.
✅100+% more PCIe lanes (8 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon HD 8180, while Pentium G645T needs a discrete GPU.

Trade-offs

❌Fewer obvious downsides in this matchup outside of normal market pricing swings.

Pentium G645T

2012

Why buy it

Trade-offs

❌Lower PassMark (1,238 vs 1,248).
❌Launch MSRP is still $64 MSRP, while A4-1200 mostly shows up through inconsistent older-market listings.
❌775% higher power demand at 35W vs 4W.
❌No integrated graphics, while A4-1200 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is A4-1200 better than Pentium G645T?

It depends on what you want from the system. For gaming, Pentium G645T is ahead with a 1.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, A4-1200 pulls ahead with 0.8% better PassMark.

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

For streaming, content creation, and heavier multitasking, A4-1200 is the stronger fit. You are getting 0.8% better PassMark, backed by 2 cores and 2 threads.

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

A4-1200 is still the much better call for a fresh build. A4-1200 comes in at an unclear MSRP at unclear MSRP versus $64 MSRP, and it still gives you 0.8% better PassMark. Pentium G645T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (19.3 vs 0.0 PassMark/$), 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?

A4-1200 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2012) 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.
