AMD Ryzen 7 5800HS vs Intel Core i5-10300H vs AMD Ryzen 9 5900HS

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.

Intel Core i5-10300H

The Intel Core i5-10300H is a fast processor for laptops with four cores based on the Comet Lake-H series (4th generation of Skylake architecture). The processor clocks at between 2.5 and 4.5 GHz (up to 4.2 with 4 cores) and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in 14nm (14nm++) process. Compared to the predecessor, the Core i5-9300H from 2019, the 10300H is clocked slightly higher (+100 MHz Base, +400 MHz Boost) and supports faster DDR4-2933 RAM.

The Comet Lake architecture is similar to Coffee Lake and offers the same features and is produced in the same 14nm process. Other than the improved clock rates, the memory controller now also supports faster DDR4-2933 RAM. More information on Comet Lake and all the models and articles on it can be found here.

The Core i5-10300H supports no vPro, TXT or SIPP. These business features are available in the faster Core i5-10400H (2.6 - 4.6 GHz) that was released at a later date.

Performance

The average 10300H in our database matches the AMD Ryzen 5 3550H in multi-thread performance. While not a poor result per se, it is indicative of an entry-level H-class CPU that is unlikely to meet the needs of hardcore gamers, professional videographers and similar clientele.

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

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a similar performance as the UHD630 in the Core i5-9300H. As a low-end solution it will probably only run current games smoothly at reduced details - if at all.

Power consumption

The Core i5 has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are free 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 i5-10300H is manufactured on one of the old 14 nm Intel processes for lower-than-average, as of late 2022, energy efficiency.

AMD Ryzen 9 5900HS

The AMD Ryzen 9 5900HS is a processor for big (gaming) laptops based on the Cezanne generation. The R9 5900HS integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 3 GHz (guaranteed base clock) to 4.6 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 7 nm TSMC process. Compared to the 5900HX (up to 54 W), the 5900HS is configured with a TDP of 35 W.

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 iGPU with 8 CUs at up to 2100 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB of Level 3 cache can be found on the chip.

Performance

The average 5900HS in our database matches the Core i7-12650H, the Core i9-11900H and the Core i9-11980HK in multi-thread performance. Surprisingly enough, it manages to come unbelievably close to the more power-hungry Ryzen 9 5900HX. This is a great CPU in all respects, and laptop makers as well as mini-PC manufacturers are taking notice.

Thanks to its decent cooling solution and a long-term CPU power limit of 80 W, the Zephyrus G14 GA401QEC is among the fastest laptops powered by the 5900HS that we know of. It can be at least 10% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Ryzen 9 series chip has a default TDP (also known as the long-term power limit) of 35 W that laptop makers aren't really required to stick to. Either way, an active cooling solution is a must for a CPU like this.

The Ryzen 9 5900HS is built with TSMC's 7 nm process for average, as of mid 2023, energy efficiency.
