Intel Core i5-8300H vs Intel Core i7-12650H vs Intel Core i5-9300HF

Intel Core i5-8300H

The Intel Core i5-8300H is a fast processor for laptops with four cores based on the Coffee Lake architecture and was announced early 2018. The processor clocks at between 2.3 and 4 GHz (3.9 with 4 cores) and can execute up to eight 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

The Intel Core i5-8300H should perform similar as the older Core i7-7820HQ (2.9 - 4 GHz). The faster Coffee Lake CPUs, like the Core i7-8750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-8300H should be sufficient for even 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 i5 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.

Intel Core i7-12650H

The Intel Core i7-12650H is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 6 performance cores (P-cores, Golden Cove architecture) and 4 of the 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 16 supported threads when combined with the E-cores. The clock rate ranges from 2.3 to 4.7 GHz on the performance cluster and 1.7 to 3.5 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 24 MB L3 cache. Compared to the 12700H, the 12650H offers only 4 instead of 8 E-cores, a slower iGPU and no vPro features (for remote management).

Performance

The average 12650H in our database is in the same league as the Core i9-11950H, Ryzen 5 7640HS, Ryzen 9 5900HS, as far as multi-thread benchmark scores are concerned. This is a very good result, as of early 2023.

Thanks to its decent cooling solution and a long-term CPU power limit of 80 W, the TUF Dash F15 FX517ZR is among the fastest laptops built around the 12650H that we know of. It can be more than 25% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

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. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics card is based on the Xe-architecture and offers 64 of the 96 EUs (Execution Units) operating at up to 1.4 GHz.

Power consumption

This Core i7 has a "minimum assured" power consumption of 35 W, with 45 W being its Base power consumption. The processor's maximum Intel-recommended Turbo power consumption sits at 115 W. It would take at least two fans to cool such a beast.

Last but not the least, Intel Core i7-12650H is built with Intel's fourth-generation 10 nm process marketed as Intel 7 for OK, as of early 2023, energy efficiency.

Intel Core i5-9300HF

The Intel Core i5-9300H is a fast processor for laptops with four cores based on the Coffee Lake architecture (2019 Refresh, CFL-HR). The processor clocks at between 2.4 and 4.1 GHz (4 with 4 cores) and can execute up to eight 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 i5-8300H from 2018, the 9300H is clocked slightly higher (+100 MHz CPU).

Compared to the Core i5-9300H, the integrated graphics card in the 9300HF is deactivated.

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

The Intel Core i5-9300HF should perform similar as the older Core i7-7920HQ (3.1 - 4.1 GHz). The faster Coffee Lake CPUs, like the Core i7-8750H/9750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-9300HF should be sufficient for even demanding applications and games. Compared to the Core i5-9300H (see for benchmarks), the performance should be identical.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i5 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.
