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.
The Intel Core i7-4980HQ is a high-end quad-core processor for laptops launched in Q3 2014. It is based on the Haswell architecture and manufactured in 22nm. Due to Hyperthreading, the four cores can handle up to eight threads in parallel, leading to better utilization of the CPU. Each core offers a base speed of 2.8 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.8 GHz (for 4 active cores), 3.9 GHz (for 2 active cores) and 4.0 GHz (for 1 active core). A noteworthy feature is the fast integrated graphics unit (GT3e) with eDRAM memory (128 MB, 77 mm², on-package, 102 GB/s).
Architecture
Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports, improving the performance per clock by almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.
Performance
Thanks to its higher clock rates, the Core i7-4980HQ is slightly faster than the former 4960HQ. However, the Turbo Boost could be limited by the TDP under long-lasting full load, leading to a slightly lower performance compared to Extreme Editions like the i7-4940MX.
Graphics
The integrated Iris Pro Graphics 5200 GPU offers 40 Execution Units (EUs) clocked at 200 - 1300 MHz (with Turbo Boost), making it significantly faster than the HD 4000 or HD 4600. The additional eDRAM memory further improves performance. As a result, the HD 5200 competes with dedicated mid-range graphics cards (e.g. GeForce GT 740M).
Power Consumption
The i7-4980HQ is rated at a TDP of 47 W including the integrated graphics card, memory controller and VRMs. Therefore, the CPU is best suited for laptops 15-inches or greater.
