AMD Ryzen 7 5700U vs AMD Ryzen 5 5600U vs AMD Ryzen 7 5800U

AMD Ryzen 7 5700U

The AMD Ryzen 7 5700U is an APU of the Lucienne product family designed for leaner laptops. The Ryzen features eight Zen 2 cores clocked at 1.8 GHz (base clock speed) to 4.3 GHz (Boost) as well as a Vega 8 iGPU. Thread-doubling SMT tech is enabled in this CPU for up to 16 concurrent processing threads.

Architecture

In spite of what its name may suggest, Ryzen 7 5700U is not a Zen 3 part, meaning this is a Ryzen 4000 series mobile processor in disguise. Nevertheless, the CPU is manufactured on the modern 7 nm TSMC process and its performance as well as energy efficiency figures are very strong compared to what Intel currently has to offer in this segment.

The Ryzen 7 features 8 MB of Level 3 cache. Its built-in memory controller is designed to work with dual-channel DDR4-3200 or quad-channel LPDDR4-4266 RAM. Unlike the desktop Ryzen 5000 processors, Ryzen 7 5700U does not support PCI-Express 4.0, meaning those speedy NVMe SSDs will be limited to read/write rates of 3.9 GB/s.

The Ryzen gets soldered directly to the motherboard (FP6 socket) and is thus not user-replaceable.

Performance

The average 5700U in our database is in the same league as the Ryzen 7 4800U, Ryzen 7 PRO 5850U, Core i7-1365U, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 35 W, the Schenker VIA 15 Pro is among the fastest laptops built around the 5700U that we know of. It can be roughly 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

In addition to its eight CPU cores, Ryzen 7 5700U features a Radeon RX Vega series graphics adapter with 8 CUs (= 512 shaders) running at up to 1,900 MHz. This iGPU trails behind the 96 EU Intel Iris Xe Graphics G7 in synthetic benchmarks, yet its real-world performance is good enough for many games released in 2020 and 2021 at reasonable resolutions (up to Full HD 1080p) and low to medium quality. As the Vega has no VRAM of its own, it is paramount that fast system RAM is used.

The graphics adapter definitely supports UHD 2160p monitors at 60 Hz, and will gladly HW-decode AVC, HEVC and VP9-encoded videos. There is no AV1 support here though.

Power consumption

This Ryzen 7 has a default TDP, also known as the long-term power limit, of 15 W; laptop makers are free to change that to anything between 10 W and 25 W, with clock speeds and performance changing accordingly as a result. Most companies will go for a higher value to extract more performance out of the APU. By choosing the lowest value, it will be possible to build a passively cooled system around the chip, too.

The 7 nm TSMC process the R7 5700U is built with makes for decent, as of late 2022, energy efficiency.

AMD Ryzen 5 5600U

The AMD Ryzen 5 5600U, not to be confused with Intel's Core i7-5600U, is a fairly fast Cezanne family processor designed for use in thinner, lighter laptops. The R5 5600U integrates six of the eight cores based on the Zen 3 microarchitecture and is the third fastest U-series processor at launch. The cores are clocked at 2.3 (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 card with 7 CUs at up to 1800 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

Performance

This Ryzen 5 series chip is a solid mid-range CPU, as of early 2022. Its multi-thread benchmark scores nearly match those of the Intel Core i5-11400H (a much more power-hungry hexa-core chip designed for use in gaming laptops). While not nearly as fast as 12th generation Alder Lake-P processors, the 5600U should be good enough for the vast majority of users.

Thanks to its decent cooling solution and a long-term CPU power limit of 30 W, the IdeaPad 5 Pro 14ACN6 is among the fastest laptops powered by the 5600U that we know of. It can be more than 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 has a default TDP of 15 W, a value that laptop makers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing accordingly as a result. By going for the lowest value possible, it is possible to build a passively cooled system around this chip. Most laptop makers, however, will do the opposite to maximize performance.

The AMD Ryzen 5 5600U is built with TSMC's 7 nm manufacturing process for average, as of mid 2023, energy efficiency.

AMD Ryzen 7 5800U

The AMD Ryzen 7 5800U is a processor for thin and light laptops based on the Cezanne generation. The R7 5800U integrates all eight cores based on the Zen 3 microarchitecture and is the fastest U-series processor at launch. They are clocked at 1.9 (guaranteed base clock) to 4.4 GHz (Turbo) and support SMT / Hyperthreading (16 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 eight CPU cores, the APU also integrates a Radeon RX Vega 8 GPU with 8 CUs at up to 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

Performance

The average 5800U in our database matches the Core i5-11260H and, perhaps a little disappointingly, the Ryzen 7 4800U in multi-core performance.

Thanks to its decent cooling solution and a long-term CPU power limit of 22 W, the ProBook x360 435 G8 is among the fastest laptops powered by the 5800U that we know of. It can be more than 10% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
