AMD Ryzen 7 4800H vs AMD Ryzen 5 5600H vs AMD Ryzen 7 5800H

AMD Ryzen 7 4800H

The AMD Ryzen 7 4800H is a Renoir APU designed for larger, more powerful laptops with room for better termals. The Ryzen features eight Zen 2 cores running at 2.9 GHz (base clock speed) to 4.2 GHz (Boost). The CPU also has 8 MB of L3 cache and a Vega series integrated GPU. Thread-doubling SMT tech is enabled in this processor, allowing for up to 16 concurrent processing threads.

Architecture

Ryzen 7 4800H is manufactured on the modern 7 nm TSMC process and in part thanks to this fact AMD promises an up to 2x higher performance-per-watt figure compared to Ryzen 3000 series mobile APUs. This isn't the only noteworthy change however as Zen 2 architecture is leagues ahead of the outgoing Zen+ when it comes to single-core performance. Renoir family processors feature up to 8 CPU cores compared to 4 cores of the previous generation mobile AMD CPUs.

A 4800H will work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. The important difference between desktop Ryzen 4000 and mobile Ryzen 4000 processors is that the latter do not have PCI-Express 4.0 support, meaning those blazing-fast NVMe SSDs will be limited to a throughput of 3.9 GB/s.

The Ryzen 7 gets soldered straight to the motherboard (FP6 socket) and is thus not user-replaceable. Please go to our Renoir processor family hub for more information on these CPUs.

Performance

The average 4800H in our database is in the same league as the Core i7-11850H, the Core i7-1360P and also the Ryzen 7 PRO 6850U, as far as multi-thread benchmark scores are concerned. This highlights just how great of a job Renoir designers did, back in the day.

Thanks to its decent cooling solution and a long-term power limit of 45 W, the MSI Alpha 17 A4DEK is among the fastest laptops built around the 4800H that we know of. It can be more than 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

Ryzen 7 4800H features the Radeon RX Vega 7, a 7 CU integrated graphics adapter running at up to 1,600 MHz. The iGPU's underlying architecture is fairly old as of 2021, yet its 448 shaders will let you play many games of 2020 and 2021 as long as you stick to reasonable resolutions and presets. F1 2021 runs well at medium quality, 1080p resolution, to give you an example. A Vega 7 can be as fast as a GeForce GTX 1050 Max-Q, or as slow as an 80 EU Iris Xe; this depends on the benchmark as well as on cooling system performance and TDP settings of a laptop as mentioned above. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.

The Vega definitely supports UHD 2160p monitors at 60 Hz. This iGPU is capable of hardware decoding AVC, HEVC and VP9-encoded videos. There is no AV1 support to be found here though. Such a video will have to be SW-decoded leading to much lower energy efficiency.

Power consumption

This Ryzen 7 series chip has a default TDP (also known as the long-term power limit) of 45 W. Laptop makers are allowed to change that to anything between 35 W and 54 W, with clock speeds and performance changing accordingly as a result. The Ryzen 7 4800HS is a 35 W edition of the Ryzen 7 4800H that trades away a bit of performance for lower power consumption. In both cases, an active cooling solution is a must.

Both the 4800H and the 4800HS are built with TSMC's 7 nm process for decent, as of late 2022, energy efficiency.

AMD Ryzen 5 5600H

The AMD Ryzen 5 5600H is a processor for big (gaming) laptops based on the Cezanne generation. The R5 5600H has six of the eight cores based on the Zen 3 microarchitecture. They are clocked at 3.3 GHz (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT for a total of 12 threads. The chip is manufactured on the modern 7 nm TSMC process.

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 six CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics processor with 7 CUs running at up to 1800 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB of L3 cache can be found on the chip.

Performance

The average 5600H in our database is in the same league as the Ryzen 5 6600HS and the Core i7-1260P, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 45 W, the Lenovo Legion 5 17 is among the fastest laptops powered by the 5600H that we know of. It can be roughly 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Ryzen 5 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 change to anything between 35 W and 54 W with clock speed and performance changing accordingly as a result. A high-performance cooling solution is a must for a CPU like this.

The hexa-core APU is built with the 7 nm TSMC process for decent, as of late 2022, energy efficiency.

AMD Ryzen 7 5800H

The AMD Ryzen 7 5800H is a high-performance octa-core processor of the Cezanne product family. It was released in Q1 2021; it is designed for use in larger laptops, primarily gaming laptops and DTRs. The Ryzen features eight SMT-enabled Zen 3 cores running at 3.2 GHz (base clock speed) to 4.4 GHz (highest Boost frequency possible) along with the Vega 8 iGPU. The chip has 16 MB of L3 cache.

Architecture

The Ryzen 7 5800H is manufactured on the modern 7 nm TSMC process, just like the outgoing Ryzen 7 4800H was; both CPUs have 8 cores and 16 threads, too. The underlying microarchitecture is what makes the two vastly different as the newer Zen 3 microarchitecture brings a massive IPC improvement over Zen 2. To be specific, AMD promises an increase of up to 19%, with independent reviews pointing to a lower (but sizeable nonetheless) 12% increase.

Ryzen 5 5800H supports dual-channel DDR4-3200 and quad-channel LPDDR4-4266 RAM. Unlike the desktop-grade Ryzen 5000-series processors, Ryzen 5 5800H does not support PCI-Express 4.0, meaning NVMe SSDs will be limited to read/write rates of 3.9 GB/s.

The CPU gets soldered straight on to the motherboard (FP6 socket interface) and is thus not user-replaceable.

Performance

The Ryzen is a marvel of a processor. As far as multi-thread benchmark scores are concerned, the average 5800H in our database trades blows with the Intel Core i5-12500H, Core i7-11800H, Core i7-12650H, Core i9-11950H and also the AMD Ryzen 9 4900H. Needless to say, a system built around this CPU will have little difficulty chewing through pretty much any workload imaginable for years to come.

With the long-term CPU power limit of 75 W, the Lenovo Legion 5 15ACH is among the fastest 5800H-toting laptops that we have tested; it can be at least 20% faster in CPU-bound workloads than the slowest laptops built around the 5800H in our database such as the HP Victus 16 or the Asus ZenBook 14X OLED.

Graphics

In addition to its eight CPU cores, the APU has the Radeon RX Vega 8 graphics adapter. Just like the name suggests, Vega 8 features 8 Compute Units (8 x 64 = 512 unified shaders); in the case of Ryzen 7 5800H, the Vega runs at up to 2,000 MHz.

On paper, this iGPU is inferior to the 96 EU Intel Iris Xe Graphics G7. However, as is usually the case, synthetic benchmarks do not tell the entire story, as AMD's drivers are superior to those of Intel. As a result, the Vega will let you play a lot of games released in 2020 and 2021 at reasonable resolutions (up to Full HD 1080p) and Low to Medium presets. Mass Effect Legendary Edition is playable at 1080p (High), to give you an example. As the iGPU has no VRAM of its own, it is paramount that fast system RAM is used.

The graphics adapter definitely supports 2160p UHD monitors at 60 Hz. AVC, HEVC, MPEG-2, VP9-encoded videos can be hardware-decoded with the Vega but there is no AV1 support here; such a video will be software-decoded for much lower energy efficiency.

Power consumption

This AMD APU has a default TDP (also known as the long-term Power Limit) of 45 W that can be changed to anything between 35 W and 54 W by laptop makers, with clock speeds and performance changing accordingly as a result. No matter the exact value, an active cooling solution is a must.

The Ryzen 7 5800H is built with TSMC's 7 nm process for very decent, as of early 2022, energy efficiency.
