Intel Processor U300 vs Intel Core i5-11300H

Intel Processor 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 one performance core (Raptor Cove architecture P-core, similar to Alder Lake) and 4 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading for 6 processing threads when combined with the E-cores. The clock rate ranges from 1.2 to 4.4 GHz on the performance cluster and 0.9 to 3.3 GHz on the efficient cluster. The per-clock performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores have access to 8 MB of L3 cache.

Performance

While we have not tested a single system powered by the U300 as of February 2024, its performance should be very similar to the outgoing Alder Lake Pentium 8505, since there is little difference between the two. The average U300 is set to be 10% to 20% behind the Ryzen 3 5300U and the Core i7-1185G7, as far as multi-thread benchmark scores are concerned, making the former an entry-level chip as of early 2024.

Your mileage may vary depending on how high the CPU power limits are.

Features

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. Several PCIe 4 lanes (x8 for a GPU and two x4 for SSDs) as well as several PCIe 3 lanes are on offer.

The integrated graphics adapter is based on the Xe architecture and offers 48 of the 96 EUs (Execution Units) operating at up to 1.1 GHz.

Power consumption

The U300 has a base power consumption of 15 W, with 55 W being its maximum Intel-recommended Turbo power consumption. The CPU is built with a 10 nm process marketed as Intel 7.

Intel Core i5-11300H

The Intel Core i5-11300H is a mid range SoC for thin and light gaming laptops and mobile workstations. It is based on the Tiger Lake H35 generation and was announced early 2021. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). The base clock speed depends on the TDP setting and can vary from 2.6 (28 W TDP) to 3.1 GHz (35 W). The boost of a single and two cores under load can reach up to 4.4 GHz. All four cores can reach up to 4 GHz. The L3 cache is reduced to 8 MB compared to the 12 MB of the higher end i7 models.

The SoC also has the improved Xe graphics adapter with 80 CUs running at up to 1,300 MHz.

Furthermore, Tiger Lake SoCs add PCIe 4 support (four lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6 in the chip.

Performance

The average 11300H in our database proves to be an OK lower mid-range CPU, as of early 2022, its multi-thread benchmark scores nearly matching those of the AMD Ryzen 3 5300U. The Core i5 will handle most day-to-day activities with ease, only sweating at the sight of latest triple-A games and similar tasks.

Thanks to its decent cooling solution and a long-term CPU power limit of 40 W, the Nitro 5 AN517-53 is among the fastest laptops built around the 11300H that we know of. It can be around 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i5 series chip has a default TDP of 28 W to 35 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, these values are way too high to allow for passively cooled designs.

The i5-11300H is built with Intel's third-generation 10 nm process marketed as SuperFin for lower-than-average, as of mid 2023, energy efficiency.
