Core i5-2390T vs Xeon L7455: Pros, Cons & Final Verdict

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

Core i5-2390T

2011

Why buy it

✅Draws 35W instead of 65W, a 30W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 2000, while Xeon L7455 needs a discrete GPU.
✅Includes a boxed cooler (Yes), unlike Xeon L7455.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon L7455 across 50 shared CPU benchmark tests.
❌Lower PassMark (2,491 vs 2,494).
❌Smaller total L3 cache (3 MB vs 12 MB).
❌Launch MSRP is still $182 MSRP, while Xeon L7455 mostly shows up through inconsistent older-market listings.

Xeon L7455

2008

Why buy it

✅Better for gaming: +10.8% higher average FPS across 50 shared CPU benchmark tests.
✅+300% larger total L3 cache (12 MB vs 3 MB).

Trade-offs

❌85.7% higher power demand at 65W vs 35W.
❌No integrated graphics, while Core i5-2390T can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Core i5-2390T.

Quick Answers

So, is Xeon L7455 better than Core i5-2390T?

Not really, because they are built for different jobs. Xeon L7455 makes more sense for workstation-style multi-core throughput, while Core i5-2390T is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon L7455 is the better pick. According to our tests, it delivers 10.8% 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, Xeon L7455 is the stronger fit. You are getting 0.1% better PassMark. It also has the larger cache pool with 300% larger total L3 cache (12 MB vs 3 MB).

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

Xeon L7455 is still the much better call for a fresh build. Xeon L7455 comes in at an unclear MSRP at unclear MSRP versus $182 MSRP, and it still gives you a 10.8% average FPS lead across 50 shared CPU game tests in our data. Core i5-2390T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 100.0% better value on paper (13.7 vs 0.0 PassMark/$), 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?

Core i5-2390T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2008). That makes it the safer long-term bet.
