Quick Answers

So, is Core i7-12700T better than Xeon E-2378G?

Not really, because they are built for different jobs. Xeon E-2378G makes more sense for workstation-style multi-core throughput, while Core i7-12700T is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Core i7-12700T is the stronger fit. You are getting 0.2% better PassMark, backed by 12 cores and 20 threads. It also has the larger cache pool with 56.3% larger total L3 cache (25 MB vs 16 MB).

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

Core i7-12700T is the better buy right now. Core i7-12700T comes in at an unclear MSRP at $339 MSRP versus unclear MSRP, and it still gives you 0.2% better PassMark. The compromise is that Xeon E-2378G is still the better pure gaming CPU with a 12.9% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (62.5 vs 0.0 PassMark/$), 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 i7-12700T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2021), a healthier platform with LGA1700 and DDR5 instead of LGA1200, 56.3% larger total L3 cache (25 MB vs 16 MB), more multi-core headroom with 12 cores / 20 threads instead of 8/16, and AVX-512 support for heavier modern compute workloads. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
