Intel Core i5-1335U vs Intel Core i7-11390H

Intel Core i5-1335U

The Intel Core i5-1335U is a mid-range mobile CPU for thin and light laptops based on the Alder Lake architecture (Raptor Lake-U / RPL-U series). It was announced in early 2023 and offers 2  performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The clock rate ranges from 1.3 to 4.6 GHz on the performance cluster and 0.9 to 3.4 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 12 MB L3 cache. The CPU supports only "Essentials" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance.

Performance

Thanks to the similar clock speed, the Core i5-1335U is very similar to the older Core i7-1250U (+100 MHz P-Cores base clock rate). The faster i7 like the i7-1365U models offer only higher clock rates (and a faster iGPU).

Architecture

The integrated memory controller supports various memory types up to LPDDR5-6400. 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. The CPU still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.

The integrated graphics card is based on the Xe-architecture and offers 80 of the 96 EUs (Execution Units) operating at up to 1.25 GHz.

Power consumption

This Core i5 CPU is rated at a TDP of 15W (base power, PL1) and a maximum turbo power of 55W (PL2). The RPL-U processors are built in a further improved Intel 7 process (10nm SuperFin) that allows higher clock rates.

Intel Core i7-11390H

The Intel Core i7-11390H is a high-end quad-core SoC for thin and light gaming laptops and mobile workstations. It is based on the Tiger Lake H35 generation and was announced in mid-2021 as a refresh. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and can vary from 2.9 (28 W TDP) to 3.4 GHz (35 W). Compared to the i7-11375H, the 11390H can now also boost with two cores up to 5 GHz and all four cores can reach a 300 MHz higher clock speed of 4.6 GHz. Both i7 use the whole 12 MB level 3 cache.

The SoC also includes the improved Xe iGPU with all 96 EUs enabled clocked at up to 1400 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 11390H in our database matches the AMD Ryzen 5 4600U and the Intel Core i7-10710U in multi-thread performance to be a decent mid-range chip, as of late 2021 - provided one isn't too picky when it comes to load times.

Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.

Power consumption

This Core i7 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, a proper coolu\ing solution is a must.

The CPU is built with Intel's third-gen 10 nm manufacturing process marketed as SuperFin for lower-than-average, as of mid 2023, energy efficiency.
