About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, productivity performance, platform differences, power efficiency, pricing context, and upgrade path so you can see which CPU actually makes more sense.

Core Ultra 7 155U

2023

Why buy it

  • Better for gaming: +3.9% higher average FPS across 4 shared CPU benchmark tests.
  • Newer platform on FCBGA2049 with DDR5 support instead of LGA2011 and DDR4.

Trade-offs

  • Smaller total L3 cache (12 MB vs 30 MB).
  • Less compelling for workstation-style loads than Xeon E5-2690 v3, which brings 12 cores / 24 threads and 40 PCIe lanes.

Xeon E5-2690 v3

2014

Why buy it

  • +150% larger total L3 cache (30 MB vs 12 MB).
  • Better for workstations and heavier parallel workloads: 12 cores / 24 threads, plus 40 PCIe lanes vs 0.
  • 100+% more PCIe lanes (40 vs 0) for storage and expansion-heavy builds.

Trade-offs

  • Worse for gaming: lower average FPS than Core Ultra 7 155U across 4 shared CPU benchmark tests.
  • Lower PassMark (16,027 vs 16,185).
  • Launch MSRP is still $2,090 MSRP, while Core Ultra 7 155U mostly shows up through inconsistent older-market listings.
  • Older platform position on LGA2011 with DDR4, while Core Ultra 7 155U moves to FCBGA2049 and DDR5.

Quick Answers

So, is Core Ultra 7 155U better than Xeon E5-2690 v3?
Not in a simple one-size-fits-all way. Xeon E5-2690 v3 makes more sense for workstation-style multi-core throughput, while Core Ultra 7 155U is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.
Which one is better for gaming?
If gaming is the priority, Core Ultra 7 155U is the better pick here. According to our tests, it delivers 3.9% more average FPS across 4 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core Ultra 7 155U is the better fit. You are getting 1% better PassMark, backed by 12 cores and 14 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core Ultra 7 155U is still the faster CPU overall, but Xeon E5-2690 v3 makes more sense if price matters more than absolute performance. Core Ultra 7 155U is at an unclear MSRP at unclear MSRP versus $2,090 MSRP, and it gives you a 3.9% average FPS lead across 4 shared CPU game tests in our data. Xeon E5-2690 v3 is also 100.0% better value on MSRP (7.7 vs 0.0 PassMark/$), which is why it is easier to justify for price-conscious builds on paper.
Which one is more future-proof for 2026 and beyond?
Core Ultra 7 155U is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2014), a healthier platform with FCBGA2049 and DDR5 instead of LGA2011, and more multi-core headroom with 12 cores / 14 threads instead of 12/24. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
