Intel Core i5-1145G7 vs AMD Ryzen 5 5600HS vs AMD Ryzen 7 5800HS

Intel Core i5-1145G7

The Intel Core i5-1145G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced early 2021. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1.1 GHz (12 Watt TDP) up to 2.6 GHz (28 Watt). The Boost is always specified at 4.4 GHz (one or two cores).

Another novelty is the integrated Xe graphics card with 80 EUs based on the completely new Gen 12 architecture. It offers a significantly higher performance compared to the older Iris Plus G7 (Ice Lake).

Furthermore, Tiger Lake SoCs add PCIe 4 support (4 lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wifi 6 in the chip. In addition to this, the i5 supports vPro for easy remote management.

The chip is produced on the improved 10nm SuperFin process at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).

AMD Ryzen 5 5600HS

The AMD Ryzen 5 5600HS is a processor for big (gaming) laptops based on the Cezanne generation. The R5 5600H integrates six of the eight cores based on the Zen 3 microarchitecture. They are clocked at 3 GHz (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured in the modern 7 nm process at TSMC. Compared to the 5600H (up to 52 W), the 5600HS is configured to a TDP of 35W.

The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.

With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 5 5600H should be clearly faster than the lower clocked Ryzen 7 4600H.

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6  integrated graphics card with 6 CUs and up to 1800 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache can be found on the chip.

The TDP of the APU is specified at 35 Watt and therefore also suited for thin gaming laptops.

AMD Ryzen 7 5800HS

The AMD Ryzen 7 5800HS is a processor for big (gaming) laptops based on the Cezanne generation. The R7 5800H integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 2.8 (guaranteed base clock) to 4.4 GHz (Turbo) and support SMT for a total of 16 threads. The chip is manufactured on the modern 7 nm TSMC process. Compared to the 5800H (up to 54 W), the 5800HS is configured to a TDP of 35W.

The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 integrated graphics adapter with 8 CUs (512 shaders) at up to 2,000 MHz. The dual channel memory controller supports dual-channel DDR4-3200 and quad-channel LPDDR4-4266 energy efficient RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

Performance

While we have not tested a single system built around the 5800HS as of August 2023, we have tested several laptops featuring the 5800H, a chip with very similar specs (Cezanne, 8 cores, 16 threads, up to 4.4 GHz). Based on that, we fully expect the 5800HS to be just slightly slower than the Core i5-12500H, Core i7-11800H, Core i7-12650H, Core i9-11950H and also the AMD Ryzen 9 4900H, as far as multi-thread benchmark scores are concerned. Which is pretty damn fast, as of late 2022.

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

Power consumption

The Ryzen has a default TDP, also known as the long-term power limit, of 35 W. A proper cooling solution is a must for a CPU like this.

This Zen 2-based APU is built with TSMC's 7 nm process for average, as of mid 2023, energy efficiency.
