Core i9-9900T

2019

Why buy it

✅+33.3% larger total L3 cache (16 MB vs 12 MB).
✅Draws 35W instead of 80W, a 45W reduction.

Trade-offs

❌Lower PassMark (13,208 vs 13,240).
❌Less compelling for workstation-style loads than Xeon E-2146G, which brings 6 cores / 12 threads and 16 PCIe lanes.
❌Launch MSRP is still $423 MSRP, while Xeon E-2146G mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while Xeon E-2146G can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Xeon E-2146G.

Xeon E-2146G

2018

Why buy it

✅Better for workstations and heavier parallel workloads: 6 cores / 12 threads, plus 16 PCIe lanes vs 0.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics P630, while Core i9-9900T needs a discrete GPU.
✅Includes a boxed cooler (Yes), unlike Core i9-9900T.

Trade-offs

❌Smaller total L3 cache (12 MB vs 16 MB).
❌128.6% higher power demand at 80W vs 35W.

Quick Answers

So, is Xeon E-2146G better than Core i9-9900T?

Not really, because they are built for different jobs. Xeon E-2146G makes more sense for workstation-style multi-core throughput, while Core i9-9900T 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 E-2146G is the better pick. According to our tests, it delivers 2.1% 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, Xeon E-2146G is the stronger fit. You are getting 0.2% better PassMark, backed by 6 cores and 12 threads.

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

Xeon E-2146G is still the faster CPU overall, but Core i9-9900T is easier to justify if budget matters more than peak performance. Xeon E-2146G comes in at an unclear MSRP at unclear MSRP versus $423 MSRP, and it still gives you a 2.1% average FPS lead across 50 shared CPU game tests in our data. Core i9-9900T is also 100.0% better value on MSRP (31.2 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i9-9900T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2018) and 33.3% larger total L3 cache (16 MB vs 12 MB). That makes it the safer long-term bet.
