Core Ultra 5 135U

2023

Why buy it

✅Better for gaming: +12.8% higher average FPS across 50 shared CPU benchmark tests.
✅Newer platform on FCBGA2049 with DDR5 support instead of FCBGA2227 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel Arc Graphics, while Xeon D-1848TER needs a discrete GPU.

Trade-offs

❌Lower PassMark (16,900 vs 16,952).
❌Smaller total L3 cache (12 MB vs 15 MB).
❌Less compelling for workstation-style loads than Xeon D-1848TER, which brings 10 cores / 20 threads.

Xeon D-1848TER

2023

Why buy it

✅+0.3% higher PassMark.
✅+25% larger total L3 cache (15 MB vs 12 MB).
✅Better for workstations and heavier parallel workloads: 10 cores / 20 threads.

Trade-offs

❌Worse for gaming: lower average FPS than Core Ultra 5 135U across 50 shared CPU benchmark tests.
❌Older platform position on FCBGA2227 with DDR4, while Core Ultra 5 135U moves to FCBGA2049 and DDR5.
❌No integrated graphics, while Core Ultra 5 135U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon D-1848TER better than Core Ultra 5 135U?

Not really, because they are built for different jobs. Xeon D-1848TER makes more sense for workstation-style multi-core throughput, while Core Ultra 5 135U 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, Xeon D-1848TER is the stronger fit. You are getting 0.3% better PassMark, backed by 10 cores and 20 threads. It also has the larger cache pool with 25% larger total L3 cache (15 MB vs 12 MB).

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

Xeon D-1848TER still makes the most sense overall. Xeon D-1848TER comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.3% better PassMark.

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

Core Ultra 5 135U makes more sense long term for 2026 and beyond. You are getting a healthier platform with FCBGA2049 and DDR5 instead of FCBGA2227. That makes it the safer long-term bet.
