Celeron G6900T

2022

Why buy it

✅Draws 35W instead of 60W, a 25W reduction.
✅Newer platform on LGA1700 with DDR5 support instead of LGA1366 and older memory support.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics 710, while Xeon L5638 needs a discrete GPU.
✅Includes a boxed cooler (Intel Stock), unlike Xeon L5638.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon L5638 across 50 shared CPU benchmark tests.
❌Lower PassMark (3,668 vs 3,707).
❌Smaller total L3 cache (4 MB vs 12 MB).
❌Less compelling for workstation-style loads than Xeon L5638, which brings 6 cores / 12 threads.
❌Launch MSRP is still $42 MSRP, while Xeon L5638 mostly shows up through inconsistent older-market listings.

Xeon L5638

2010

Why buy it

✅Better for gaming: +9.8% higher average FPS across 50 shared CPU benchmark tests.
✅+200% larger total L3 cache (12 MB vs 4 MB).
✅Better for workstations and heavier parallel workloads: 6 cores / 12 threads.

Trade-offs

❌71.4% higher power demand at 60W vs 35W.
❌Older platform position on LGA1366, while Celeron G6900T moves to LGA1700 and DDR5.
❌No integrated graphics, while Celeron G6900T can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Celeron G6900T.

Quick Answers

So, is Xeon L5638 better than Celeron G6900T?

Not really, because they are built for different jobs. Xeon L5638 makes more sense for workstation-style multi-core throughput, while Celeron G6900T 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 L5638 is the better pick. According to our tests, it delivers 9.8% 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 L5638 is the stronger fit. You are getting 1.1% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 200% larger total L3 cache (12 MB vs 4 MB).

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

Xeon L5638 is still the faster CPU overall, but Celeron G6900T is easier to justify if budget matters more than peak performance. Xeon L5638 comes in at an unclear MSRP at unclear MSRP versus $42 MSRP, and it still gives you a 9.8% average FPS lead across 50 shared CPU game tests in our data. Celeron G6900T is also 100.0% better value on MSRP (87.3 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Celeron G6900T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2010) and a healthier platform with LGA1700 and DDR5 instead of LGA1366. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
