Intel Core i7-9750H vs Intel Core i7-1355U vs Intel Core i7-8750H

Intel Core i7-9750H

► remove from comparison Intel i7-9750H

The Intel Core i7-9750H is a high-end processor for laptops with six cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.6 and 4.5 GHz (4 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the predecessor, the Core i7-8750H, the 9750H offers improved clock rates and a larger L3 cache.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now max. eight cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Multi-thread performance is most comparable to the Intel Core i9-8950HK, an expensive hexa-core processor of the previous generation. While performance gains over the outgoing 8th Gen H-class chips are unimpressive to say the least, the average Core i7-9750H in our database is much faster than the Ryzen 7 3750H and other H-class Ryzen chips AMD sells as of mid 2019.

Thanks to its decent cooling solution and a long-term power limit of around 70 W, the Walmart EVOO Gaming 17 is among the fastest laptops powered by the 9750H that we know of. It can be 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

The integrated Intel UHD Graphics 630 is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz compared to the UHD 630 of the 8750H CPU. The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power consumption

This Core i7 series chip has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are allowed to reduce slightly, 35 W being the lowest Intel-recommended value. Doing so would result in lower clock speeds and lower performance. Either way, a proper cooling solution is a must for a CPU like this.

The hexa-core Intel CPU is made with one of the old 14 nm Intel processes for below average, as of late 2022, energy efficiency.

Intel Core i7-1355U

► remove from comparison Intel i7-1355U

The Intel Core i7-1355U is a high-end 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 1.7 to 5 GHz on the performance cluster and 1.2 to 3.7 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 "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 high clock speed, the Core i7-1355U should perform slightly better than the older core i7-1265U (up to 4.8 GHz). 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 all 96 EUs (Execution Units) operating at up to 1.3 GHz.

Power consumption

This Core i7 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 i7-8750H

► remove from comparison Intel i7-8750H

The Intel Core i7-8750H is a high-end processor for laptops with six cores based on the Coffee Lake architecture and will be announced early 2018. The processor clocks at between 2.2 and 4.1 GHz (4 GHz with 4 cores, 3.9 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Due to the two additional cores, performance has increased by almost 50% compared to a similar clocked Kaby Lake processor like the Core i7-7820HQ (2.9 - 3.9 GHz). Single-core performance has not improved since its Kaby Lake predecessor. As a high-end model, the i7-8850H is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz (rumored). The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i7 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
