The Ryzen 7 5800H: A Review of its Performance, Graphics, and Power Consumption

Ryzen 7

AMD introduced the high-performance Cezanne product family Ryzen 7 5800H octa-core processor. It is a marvel of a processor with very high scores on all benchmarks and is intended for use in larger laptops, primarily gaming laptops and DTRs.


In line with the Ryzen 7 4800H that it replaces, the Ryzen 7 5800H is produced using the most recent 7 nm TSMC process. Though independent reviews suggest a lower but still sizable 12 percent increase, the Zen 3 microarchitecture over Zen 2 offers a significant improvement with a promised increase of up to 19 percent in IPC.

DDR4-3200 dual-channel and LPDDR4-4266 quad-channel RAM are both supported by the Ryzen 5 5800H. The Ryzen 5 5800H, unlike the desktop-grade Ryzen 5000-series processors, does not support PCI-Express 4.0, so NVMe SSDs will only be able to read/write data at a rate of 3.9 GB/s. It is not possible to replace the CPU because it is soldered directly to the motherboard.


The average 5800H competes favorably in multi-thread performance with the Intel Core i5-12500H, Core i7-11800H, Core i7-12650H, Core i9-11950H, and AMD Ryzen 9 4900H. For years to come, this CPU will have no trouble handling just about any workload imaginable, with performance varying based on a laptop's Power Limits and cooling system.


The Radeon RX Vega 8 graphics adapter, which has 8 Compute Units (8 x 64 = 512 unified shaders), is another feature of the APU. On paper, the iGPU is inferior to the 96 EU Intel Iris Xe Graphics G7, but AMD's drivers outperform Intel's and enable playable performance at reasonable presets and resolutions. The graphics adapter does not support AV1, but it does support 2160p UHD monitors at 60 Hz with hardware-decoded AVC, HEVC, MPEG-2, and VP9 videos.

Utilization of energy

The Ryzen 7 5800H is an APU with a relatively low TDP of 45 W, which an OEM can change to a value between 35 and 54 W. No matter the precise value chosen, a high-performance cooling solution is necessary.

Temperature and Power Consumption

The default TDP (Thermal Design Power) for the Ryzen 7 5800H is 45W, but an OEM may change it to anything between 35W and 54W if they so choose. Due to the 7nm manufacturing process, this APU is regarded as energy-efficient; however, for optimum performance, a high-performance cooling solution is still required. The Ryzen 7 5800H can withstand temperatures up to 105°C.


Numerous features, including XFR (eXtended Frequency Range), FMA3, SSE 4.2, AVX2, and SMT (Simultaneous Multi-Threading), are supported by the Ryzen 7 5800H. Additionally, it supports 64-bit architecture, making it compatible with the majority of contemporary systems.


For larger laptops like gaming laptops and DTRs, the AMD Ryzen 7 5800H is an octa-core processor with high performance and power. Its impressive performance is a result of its cutting-edge 7nm manufacturing process, 3 and 2 GHz base and 4 and 4 GHz boost frequencies, and 16 MB L3 cache. The Ryzen 7 5800H is an excellent choice for people looking for a high-performance laptop because it has an integrated Vega 8 iGPU that offers respectable graphics capabilities as well.
