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

Core i5-4288U

2013

Why buy it

✅+1.1% higher PassMark.
✅100+% more PCIe lanes (12 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel Iris Graphics 5100, while FX-4100 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (3 MB vs 8 MB).
❌Lower PassMark per dollar, at 7.8 vs 22.9 PassMark/$ ($342 MSRP vs $115 MSRP).
❌438.9% higher power demand at 512W vs 95W.

FX-4100

2011

Why buy it

✅+166.7% larger total L3 cache (8 MB vs 3 MB).
✅Costs $227 less on MSRP ($115 MSRP vs $342 MSRP).
✅Delivers 194.1% more PassMark for each dollar spent, at 22.9 vs 7.8 PassMark/$ ($115 MSRP vs $342 MSRP).
✅Draws 95W instead of 512W, a 417W reduction.

Trade-offs

❌Lower PassMark (2,630 vs 2,659).

Quick Answers

So, is FX-4100 better than Core i5-4288U?

It depends on what you want from the system. For gaming, FX-4100 is ahead with a 0.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-4288U pulls ahead with 1.1% better PassMark. FX-4100 also has the bigger cache pool with 166.7% larger total L3 cache (8 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-4288U is the stronger fit. You are getting 1.1% better PassMark, backed by 2 cores and 4 threads.

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

FX-4100 is the better buy right now. FX-4100 comes in $227 cheaper on MSRP at $115 MSRP versus $342 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-4288U is still stronger for heavier multi-core work with 1.1% better PassMark. It is also 194.1% better value on MSRP (22.9 vs 7.8 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i5-4288U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2011) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
