AMD Ryzen 5 5600U vs Intel Celeron 3867U vs Intel Core i7-7500U

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.

Intel Celeron 3867U

The Intel Celeron 3865U is an ULV (ultra low voltage) dual-core SoC based on the Kaby-Lake architecture and has been launched in the first quarter of 2017. The CPU can be found in ultrabooks as well as normal notebooks. In addition to two CPU cores clocked at 1.8 GHz (no Turbo Boost, no HyperThreading), the chip also integrates an HD Graphics 610 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The SoC is manufactured using a 14 nm process with FinFET transistors.

Compared to the similar Celeron 3865, the 3867 offers a different cTDP-down option (12.5 versus 10 Watt).

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

Due to the missing Turbo Boost and the low clock speeds, especially the single thread performance is very limited which results in a lower performance even for lower demanding tasks. The performance should be noticeably slower than the Celeron 3965 which offers 400 MHz higher clocked CPU cores. Therefore, the CPU is only suited for entry level tasks like office, web surfing and multimedia.

Graphics

The integrated graphics unit called HD Graphics 610 (similar to the HD Graphics 510) represents the "GT1" version of the Kaby Lake GPU (Intel Gen. 9). Its 12 Execution Units, also called EUs, are clocked at 300 - 900 MHz and offer a performance somewhat below the older HD Graphics 4400. Only a few games of 2015 can be played smoothly in lowest settings.

Power Consumption

Specified at a TDP of 15 W (including CPU, GPU and memory controller), the CPU is best suited for small notebooks and ultrabooks (11-inches and above). Optionally, the TDP can be lowered to 10 watts (cTDP down), reducing both heat dissipation and performance and allowing even more compact designs.

Intel Core i7-7500U

The Intel Core i7-7500U is a dual-core processor of the Kaby Lake architecture. It offers two CPU cores clocked at 2.7 - 3.5 GHz and integrates HyperThreading to work with up to 4 threads at once. The architectural differences are rather small compared to the Skylake generation, therefore the performance per MHz is very similar. The SoC includes a dual channel DDR4 memory controller and Intel HD Graphics 620 graphics card (clocked at 300 - 1050 MHz). It is manufactured in an improved 14nm FinFET process (14nm+) at Intel. Compared to the old Skylake Core i7-6500U (2.5 - 3.1 GHz), the i7-7500U clock speed is up to 400 MHz higher.
