Quick Answer
The Intel Core i5-1335U and i5-1334U are closely related 10-core, 12-thread mobile processors. The primary difference is that the i5-1335U features a slightly higher maximum Turbo Boost frequency for its performance cores (4.6 GHz vs. 4.5 GHz) and its integrated Iris Xe Graphics (80 Execution Units vs. 48 EUs), which typically results in better graphics performance.
Intel Core i5 1335U vs Intel Core i5 1334U: Full Comparison
Introduction
Choosing the right processor for a laptop involves understanding subtle differences between models. The Intel Core i5-1335U and Core i5-1334U are both part of Intel’s 13th Gen Raptor Lake-U series, designed for thin-and-light laptops that balance performance and efficiency. This comparison breaks down their specifications, performance characteristics, and typical use cases to help clarify which chip might be more suitable for specific needs, focusing purely on their technical attributes.
Core Architecture and Performance
Both processors share a very similar hybrid core architecture, but there are minor differences in clock speeds that can influence performance.
- Core Configuration: Both CPUs feature an identical hybrid design with 2 Performance-cores (P-cores) and 8 Efficient-cores (E-cores), for a total of 10 cores and 12 threads.
- Clock Speeds: The base clock speeds are the same (1.3 GHz for P-cores, 0.9 GHz for E-cores). The key difference lies in the maximum Turbo frequency. The i5-1335U can boost its P-cores up to 4.6 GHz, while the i5-1334U has a slightly lower maximum of 4.5 GHz. This can translate to a marginal advantage for the 1335U in short, bursty single-threaded tasks.
- Cache: Both processors have 12 MB of Intel Smart Cache.
- Real-World Impact: For everyday tasks like web browsing, office applications, and video conferencing, the performance difference is generally negligible. The higher turbo clock of the 1335U might be more noticeable in applications that are lightly threaded and sensitive to peak clock speeds.
Integrated Graphics
This is one of the most significant differentiating factors between these two processors.
- Intel Core i5-1335U: Equipped with Intel Iris Xe Graphics featuring 80 Execution Units (EUs).
- Intel Core i5-1334U: Equipped with Intel UHD Graphics (based on the Xe architecture) featuring 48 Execution Units (EUs).
- Performance Difference: The i5-1335U, with its higher EU count, offers notably better graphics performance. This makes it more capable for light photo and video editing, casual gaming at lower settings, and smoother performance in graphics-intensive applications. The i5-1334U’s UHD Graphics is sufficient for display output, video playback, and very basic graphical tasks.
Power and Platform Features
Both chips are designed for the same class of devices and share nearly identical platform capabilities.
- TDP (Thermal Design Power): Both processors have a base TDP of 15 watts, with configurable TDP-down and TDP-up ranges that allow laptop manufacturers to tune them for different device designs, from ultra-portables to more performance-oriented thin-and-lights.
- Memory Support: Both support dual-channel DDR5-5200 MT/s and LPDDR5/x-6400 MT/s memory, as well as older DDR4-3200 and LPDDR4x-4267.
- Connectivity: They integrate the same platform controller hub, supporting features like PCIe 4.0 lanes, Thunderbolt 4, Wi-Fi 6E (Gig+), and modern I/O standards.
