AMD Ryzen 5 3500U vs Intel Core i7-10610U vs Intel Pentium Gold 6405U

AMD Ryzen 5 3500U

The AMD Ryzen 5 3500U is a mobile SoC that was announced in January 2019. It combines four Zen+ cores (8 threads) clocked at 2.1 GHz to 3.7 GHz with a Radeon RX Vega 8 iGPU with 8 CUs (512 Shaders) clocked at up to 1200 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops. In Chromebooks, AMD calles the APU AMD Ryzen 5 3500C, but the specifications (and performance) are the same.

The Picasso SoC uses the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. Furthermore, the 12 nm process allows for higher clocks at similar power consumption.

The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

Performance

The average 3500U in our database matches the Intel Core i7-1065G7 in multi-thread performance to be an OK lower mid-range option, as of early 2021.

The Honor MagicBook 14 is among the fastest laptops powered by the 3500U that we know of. It can be up to 50% 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 15 W, a value that laptop makers are free to set to anything between 12 W and 35 W with clock speeds and performance changing accordingly as a result. Either way, this is a tad too high to allow for passively cooled designs.

The chip is manufactured on a 12 nm process for subpar, as of late 2022, energy efficiency.

Intel Core i7-10610U

The Intel Core i7-10610U is a power efficient quad-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in August 2019. Compared to the similar Whiskey Lake processors (e.g. Core i7-8665U), the only difference is support for higher memory speeds (DDR4-2666 vs 2400) and two additional cores in the top model (not in this i7-10610U). The processor cores are clocked between 1.8 and 4.9 GHz (unverified). Thanks to Hyper-Threading 8 threads can be used. More information on Comet Lake and all the models and articles on it can be found here.

Compared to the similar Core i7-10510U, the 10610U supports vPro.

The integrated graphics adapter however is still the same as in the previous generations. It should be still called Intel UHD Graphics 620 and clock from 300 - 1150 MHz in the i7. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel DDR4-2666 / LPDDR4x 2933 / LPDDR3-2133 memory controller.

Performance

The average 10610U in our database is in the same league as the Core i5-1035G1 and also the Core i5-8257U, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term power limit of 25 W, the HP ZBook Firefly 14 G7 is among the fastest laptops built around the 10610U that we know of. It can be about 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i7 has a default TDP of 15 W (also known as the long-term power limit). Laptop manufacturers are free to change that value to anything between 10 W and 25 W, with clock speeds and performance changing accordingly. Perhaps more importantly, short-term power consumption of 10th gen Comet Lake U processors can be as high as 80 W or even 90 W, making passively cooled designs rather unlikely to appear.

Core i7-10610U is manufactured on an old, as of late 2022, 14 nm Intel process for subpar energy efficiency.

Intel Pentium Gold 6405U

The Intel Pentium Gold 6405U is a power efficient entry-level dual-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in October 2019. Compared to the similar Whiskey Lake Pentium 5405U processors, the difference is the higher clock speed (+100 MHz) and support for faster memory. The processor cores are clocked at 2.4 GHz (no Turbo). Thanks to HyperThreading 4 threads can be used. More information on Comet Lake and all the models and articles on it can be found here.

Due to the 100 MHz higher clock speed, the Pentium Gold 6405U should be slightly faster than the old Pentium 5405U and therefore in the entry level of mobile processors. The missing Turbo and only two cores are definitely a downside and therefore the CPU is best used for simple tasks like browsing and office programs. Compared to the faster Core i3, i5 and i7 Comet Lake models, the Pentium does not support SSE (2).

The integrated graphics card is still the same as in the previous generations. It is called only Intel UHD Graphics but is still the same Intel UHD Graphics 610 like in the Pentium 5405U. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel LPDDR3-2133/DDR4-2400 memory controller (compared to DDR4-2666 in the faster Core i3).

The chip is still produced in the 14nm++ process as Whiskey Lake. The TDP (PL1) is specified at 15 Watts but can be lowered to 12.5 Watt although the CPU then only runs at 800 MHz.
