Introduction
You walk into a laptop store in 2025, staring at rows of shiny new machines. A sales rep points at one sticker: Intel Core Ultra 7 155U. It sounds powerful, but is it really the right chip for you?
This processor, part of Intel’s first-generation Core Ultra Meteor Lake series, has been making its way into premium laptops worldwide. From Lenovo ThinkPads to HP EliteBooks, it promises efficiency, AI-ready performance, and a balance between speed and battery life.
But is the It worth your money? In this guide, we’ll break down specs, benchmarks, comparisons with AMD Ryzen, real-world performance, and the best laptops you can buy with it today.
What is the Intel Ultra 7 155U?
The Intel Core Ultra 7 155U was launched in December 2023, introducing Intel’s new Meteor Lake architecture. Instead of a single monolithic design, Intel split the chip into multiple “tiles” (CPU, GPU, IO, and SoC). This modular approach allows better power efficiency and performance tuning.
Core & Thread Layout
- 12 cores, 14 threads
- 2 Performance cores (P-cores)
- 8 Efficiency cores (E-cores)
- 2 Low-Power Efficiency cores (LPE-cores)
This hybrid setup ensures that demanding apps (like Photoshop or code compiling) use P-cores, while lighter tasks (like background updates) run on E-cores or LPE-cores, saving battery.
Manufacturing
- CPU Tile: Intel 4 (7nm EUV)
- GPU & SoC Tiles: TSMC N5 / N6 nodes
- Base Tile: Intel 22FFL
This is Intel’s first consumer chip mixing its own fabrication with TSMC technology a shift that helps balance cost, heat, and performance.
Key Takeaways:
- Meteor Lake = Intel’s most modular laptop CPU yet.
- Ultra 7 155U = efficiency-focused U-series (ultra-portables).
- Best for thin, business-class laptops, not gaming rigs.
Intel Ultra 7 155U Specifications at a Glance
Here’s a quick look at the official spec sheet:
| Feature | Details |
|---|---|
| Launch Date | Q4 2023 (Meteor Lake 1st Gen Core Ultra) |
| Cores / Threads | 12 (2P + 8E + 2 LP-E) / 14 threads |
| Base Clock | ~1.7 – 2.0 GHz (varies by laptop) |
| Boost Clock (P-cores) | Up to 4.8 GHz |
| L3 Cache | 12 MB |
| TDP Range | 12W – 57W (depending on workload & OEM tuning) |
| Integrated GPU | Intel Arc GPU (64 Execution Units, 4 Xe cores) |
| Memory Support | DDR5-5600, LPDDR5x-7467 |
| PCIe Support | PCIe 4.0 |
This chip balances high clock speeds on P-cores with low power draw on E-cores, making it perfect for ultrabooks.
Performance & Benchmarks
So how does the Ultra 7 155U perform in real life?
Synthetic Benchmarks
- PassMark Score: ~21,000 (good for a U-series chip).
- Geekbench 6 Multi-core: ~11,000.
- NotebookCheck ranking: “Upper mid-range efficiency processor.”
While not a powerhouse like Intel’s H-series chips or AMD Ryzen 9, it performs more than well enough for productivity, web browsing, coding, and light creative work.
Real-World Use
- Office & Browsing: Smooth, even with 20+ Chrome tabs.
- Video Calls & Multitasking: Excellent, thanks to E-cores handling background tasks.
- Photo Editing (Lightroom/Photoshop): Fast previews, snappy exports.
- Casual Gaming: Intel Arc GPU can handle games like Valorant or Fortnite at medium settings but don’t expect AAA titles at ultra.
On Reddit, many ThinkPad users mention battery life improvements over AMD chips, though AMD still leads in integrated graphics.
Key Takeaways:
- Great for everyday tasks and office workloads.
- Solid battery life a big win for business laptops.
- Casual gaming possible, but not a gamer’s CPU.
