The Intel U300: An Entry-Level Mobile CPU for Thin and Light Laptops

Intel U300

The Intel Processor U300 is an entry-level mobile CPU for thin and light laptops of the Raptor Lake-U series. It was announced in early 2023 and offers a unique combination of performance and efficiency features.

Performance Cores

The U300 features one performance core (P-core) which uses the Golden Cove architecture, similar to the Alder Lake CPU. The P-core also supports Hyper-Threading, which allows for an additional 6 threads when combined with the E-cores. The clock rate for the P-core ranges from 1.2 to 4.4 GHz.

Efficient Cores

In addition to the P-core, the U300 also has 4 efficient cores (E-cores) that use the Gracemont architecture. These cores have a clock rate range of 0.9 to 3.3 GHz, and their performance should be similar to old Skylake cores. The CPU also includes 8MB L3 cache for all cores.


In terms of performance, the U300 should be similar to the old Alder Lake Pentium 8505, with the main difference being the higher supported LPDDR5 frequency. It is also similar to the Core i3-1305U, but with more L3 cache and a higher boost clock speed for the P-core.


The U300 has a variety of memory support options, including DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. It also includes a Thread Director, which allows the operating system to select the best thread to use on the performance or efficient cores for optimal performance. Additionally, the CPU includes GNA 3.0 and DL Boost (via AVX2) for AI tasks, and Quick Sync in version 8 for video decoding. The U300 also supports PCIe 4.0, with x8 for a GPU and two x4 for SSDs.

Integrated Graphics

The U300 features an integrated graphics adapter that is based on the Xe-architecture and has 48 of the 96 EUs (Execution Units) operating at up to 1.1 GHz.

Power Consumption

The U300 has a base power consumption of 15W and a maximum Intel-recommended Turbo power consumption of 55W. It is built using Intel's improved 10nm SuperFin process, also known as Intel 7.

Comparison to Other Intel CPUs

When compared to other Intel CPUs, the U300 falls in the middle to lower range of the Raptor Lake-U series, with a lower clock rate and fewer cores/threads than models like the Core i7-1365U, but more L3 cache than the Core i3-1305U.

Overall, the Intel Processor U300 offers a balance of performance and efficiency features for thin and light laptops, with the additional benefit of integrated Xe graphics, improved memory support and latest version of QuickSync.

The U300 processor is ideal for users who are looking for a compact, lightweight laptop for basic and everyday tasks. The P-core provides enough performance for most demanding workloads, like running some resource-intensive applications, video and photo editing, and basic gaming. The E-cores offer great power efficiency, and are ideal for everyday tasks like web browsing, office work, and video streaming.

The integrated Xe graphics also makes the U300 an attractive option for users who want to do some light gaming or video editing without the need for an additional GPU. The integrated graphics adapter offers 48 Execution Units operating at up to 1.1 GHz, and it supports DirectX 12, OpenGL 4.5, and OpenCL 2.1.

Moreover, The Thread Director technology, in hardware, can support the operating system to decide which thread to use on the performance or efficient cores for the best performance, help to balance between power efficiency and performance.

The U300 also includes GNA 3.0 and DL Boost (via AVX2) for AI tasks, which means that it can run machine learning and deep learning workloads more efficiently, making it an attractive option for users who want to use their laptops for data science, machine learning, and AI-related tasks.

Lastly, Quick Sync in version 8 supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. This means that the CPU can handle video decoding tasks more efficiently, leading to better battery life and improved performance while playing or editing videos.

In conclusion, the Intel Processor U300 is a great option for users who are looking for a compact, lightweight laptop for basic and everyday tasks. It offers a balance of performance and efficiency features, with the added benefit of integrated Xe graphics and AI-related technologies. The U300 is a part of Raptor Lake-U series which will be the next line of processors for ultra-portable laptops.
