Intel Core Ultra 7 155U Benchmarks, Linux Performance

The Intel Core Ultra 7 155U is a 12-core, 14-thread "Meteor Lake" processor designed for highly portable laptops, featuring a hybrid architecture (2P, 8E, 2LPE) that prioritizes efficiency with a 15W base power, capable of boosting up to 4.8GHz. It offers excellent power-to-performance for everyday tasks, boasting a dedicated 11 TOPS NPU for AI tasks, alongside support for LPDDR5x-7467 memory. Key limitations, particularly highlighted on OpenBenchmarking.org and in comparative tests, include significantly lower multi-threaded performance (roughly 34% slower) than the H-series counterparts and limited graphics performance from its 4-core Arc GPU.

Intel Core Ultra 7 155U - CPU Benchmarks

The Intel Core Ultra 7 155U is a 12-core, 14-thread "Meteor Lake-U" processor designed for thin-and-light laptops, offering a ~3,315 single-thread PassMark score for daily productivity. Its core strengths include excellent 15W TDP power efficiency, an integrated AI Boost NPU, and support for high-speed LPDDR5x-7467 RAM. However, the chip's 4-core Arc Graphics and limited 12MB L3 cache result in roughly 34% lower multi-threaded performance compared to H-series counterparts, making it less suitable for heavy content creation or intense gaming.

Intel Core Ultra 7 155U Benchmarks - Geekbench Browser

The Intel Core Ultra 7 155U is a Meteor Lake-U processor designed for power-efficient, thin-and-light laptops, featuring 12 cores (2P, 8E, 2LPE) and a 4-core Intel Graphics iGPU geared toward productivity and light gaming. Its 15W base power and "Low Power Island" architecture prioritize battery life, supported by modern features like an NPU for AI acceleration and support for fast LPDDR5x RAM, making it suitable for office professionals. However, with significantly lower multi-threaded performance than "H" series variants and an NPU that falls short of top-tier AI requirements, it sacrifices raw power for efficiency.

Durabook S14I (2026) Review: A Semi-Rugged Marathon Runner Would you like a performance comparison between the 155U and its higher-powered sibling, th...

The Durabook S14I (2026) is a 14-inch semi-rugged laptop featuring an Intel Core Ultra 7 155U processor, designed with a durable, mostly metal chassis to withstand drops and an IP53 rating for water and dust resistance. It provides excellent performance for field work, featuring a 1,000-nit sunlight-readable display, though it is heavier than some competitors. A major highlight is its exceptional battery life, lasting over 29 hours in testing, accompanied by, however, a very long charging time. The laptop’s main strengths include high durability, superior connectivity (Wi-Fi 7), and strong modularity, including a hot-swappable battery and flexible configuration options. On the downside, it suffers from long recharge times, average audio quality, and a keyboard that may cause fatigue over long periods. Overall, the S14I represents a highly capable, rugged option for users requiring long-lasting performance in challenging environments. Copy

HP Envy x360 14 (2024) - Review 2024

The HP Envy x360 14 (2024) is a mid-range, 2-in-1 convertible praised for its sturdy aluminum design, excellent keyboard, and vibrant 2.8K 120Hz OLED display. It features a practical port selection including Thunderbolt 4, HDMI, and USB-A, making it a strong contender for users prioritizing build and screen quality. However, the laptop’s performance is hindered by a low-wattage Intel Core Ultra 7 155U processor, which lags behind competitors in demanding, creative tasks. While handling daily office tasks effectively, it falls short in raw power, and the audio experience is marred by poor, distorting down-firing speakers. Despite respectable 15.5-hour battery life, it does not offer a significant advantage over competitors, and the physical webcam shutter design is reportedly difficult to use. Copy

Lenovo ThinkBook 14 2-in-1 G4 IML, Ultra 7 155U Review

The Lenovo ThinkBook 14 2-in-1 G4 IML, reviewed by Notebookcheck, is a business-focused convertible featuring a revised 16:10 chassis that provides a professional metal alloy design. While the build is satisfactory, it is less rigid than premium, higher-end alternatives. Key strengths include a revised, spill-resistant keyboard with improved key layout and a large, firm-clicking clickpad, along with a full sRGB coverage display. Performance is driven by Intel Core Ultra U-series processors, but the integrated 4-core graphics represent a bottleneck, offering limited gaming capability suitable only for low-setting, casual use. The display, while color-accurate, is a standard 60 Hz IPS panel lacking the high contrast and HDR performance of more expensive OLED competitors. Copy

Summary of the review

Living With Lenovo's ThinkPad X1 2-in-1 Gen 9

The Lenovo ThinkPad X1 2-in-1 Gen 9 is a premium, durable business convertible featuring an excellent keyboard, robust port selection, and a lightweight, all-metal chassis. However, the review highlights significant drawbacks, including underwhelming performance, mediocre battery life, and a subpar, fuzzy 1080p webcam. While it excels in build quality and input experience, the high price point makes it a choice better suited for loyal ThinkPad users rather than those seeking the best performance-per-dollar, with an OLED display upgrade strongly recommended over the base IPS panel.

Summary of the review

Intel Core Ultra 7 155U - CPU Benchmarks (German version available)

The Intel Core Ultra 7 155U is a 15W Meteor Lake processor designed for thin-and-light laptops, featuring 12 cores (2 Performance, 8 Efficient, 2 Low Power E-cores) and a 4.8 GHz boost clock. It shines in efficiency, utilizing a dedicated Low Power Island for better battery life and an NPU for AI tasks, while supporting modern standards like LPDDR5x and Wi-Fi 7. However, with only two performance cores, it is roughly 13% slower in multi-threaded tasks than older 28W chips like the i7-1360P, and its 4-core integrated graphics are only suited for low-setting gaming.

Summary of the review

Intel Core Ultra 7 155U - LaptopMedia

The Intel Core Ultra 7 155U is a 12-core, 14-thread Meteor Lake-U processor designed for high energy efficiency and everyday productivity, utilizing a 15W base power and specialized "Low Power Island" efficient cores. It prioritizes power-to-efficiency over raw performance, featuring a dedicated AI Boost NPU and support for modern connectivity like Thunderbolt 4. While offering excellent battery life, the chip's 4-core Arc integrated graphics are limited to light gaming, and its raw multi-threaded performance is constrained compared to higher-tier H-series processors.

Third-party reviews

What we like about Intel Core Ultra 7 155U

Excellent power efficiency and idle power management, leading to long battery life (up to 14+ hours in some systems)
Strong single-core performance and snappy response for daily productivity, web browsing, and office work
Lower heat output and thermal stability, with some users reporting fewer crashes and no overheating compared to higher-wattage models
Integrated NPU provides hardware acceleration for AI-enabled tasks like Windows Defender and media background effects
Modern connectivity features including built-in support for Thunderbolt 4 and high-speed LPDDR5x RAM

What we don't like about Intel Core Ultra 7 155U

Significantly lower multi-threaded performance compared to the Core Ultra 7 155H due to fewer performance cores
Integrated 'Graphics 4-Core' iGPU is weaker than the 'Arc Graphics 8-Core' found in H-series chips, limiting it to low-setting 1080p gaming
Reduced L3 cache (12 MB vs 24 MB in H-series) can bottleneck data-heavy workloads
Sustained performance can be inconsistent, with some users noticing 'throttling' or speed drops during heavy data crunching
Generally outperformed by competing AMD Ryzen 7 (e.g., 7840U/8840U) models in both multi-threaded tasks and gaming graphics

Verdict

The Intel Core Ultra 7 155U is a power-efficient Meteor Lake-U laptop processor featuring 12 physical cores (2 Performance, 8 Efficient, and 2 Low Power Efficient cores) and 14 threads, with a max turbo frequency of 4.8 GHz and a 12 MB L3 cache. Built on the Intel 4 process (7nm), it highlights a modular tile architecture that includes a dedicated NPU for AI acceleration and 4-core Intel Graphics with a 1.95 GHz turbo speed. Its main pros include an exceptionally low 15W base TDP for extended battery life in thin-and-light devices, support for high-speed LPDDR5x-7467 memory, and advanced AI hardware for modern workloads. However, its primary cons are the significantly reduced L3 cache and lower core count compared to 'H' series variants, which limits its performance in heavy multi-threaded tasks and demanding AAA gaming.
