The Intel Core i7-4500U is an ULV (ultra low voltage) dual-core processor for ultrabooks launched in Q2 2013. It is based on the Haswell architecture and is manufactured in 22nm. Due to Hyper-Threading, the two cores can handle up to four threads in parallel, leading to better utilization of the CPU. Each core offers a base speed of 1.8 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.0 GHz for 1 active core or 2.7 GHz for 2 active cores.
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.
The performance of the Core i7-4500U is similar to the old and slightly higher clocked Core i7-3537U. However, when using new instruction sets such as AVX2 the performance can be significantly better. Thus, the CPU has sufficient power for office and multimedia purposes as well as more demanding applications.
The integrated HD Graphics 4400 offers 20 Execution Units (EUs) clocked at 200 - 1100 MHz with Turbo Boost, making it somewhat faster than the former HD Graphics 4000. However, the HD 4400 is significantly slower than the HD 5000 found on a number of other ULV models.
The i7-4500U is rated at a TDP of 15 W including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for small ultrabooks 11-inches or greater.
The AMD Ryzen 5 3550H 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 graphics adapter with 8 CUs (512 Shaders) clocked at up to 1,200 MHz. Compared to the similar Ryzen 5 3500U, the 3550H offers a 20 Watt higher TDP and therefore a better performance under long periods of load. 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.
The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. Furthermore, the 12 nm process allows higher clock rates at similar power consumptions.
Performance
The average 3550H in our database proves to be a solid mid-range CPU, its multi-thread benchmark scores hovering close to those of the Intel Core i7-10710U and the Core i5-8257U. Which is a little slow for an H-class processor, as of late 2021, but still more than enough for the vast majority of apps and games, provided one is fine with having to wait a little longer than usual for that 4K video encoding job to get completed.
Thanks to its decent cooling solution and sufficiently high CPU power limits, the Pavilion Gaming 15-ec0002ng is among the fastest laptops powered by the 3550H 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.
Power consumption
This Ryzen 5 series chip has a default TDP (also known as the long-term power limit) of 35 W. Laptop makers are free to reduce that value significantly with 12 W being the minimum AMD-recommended value. Clock speeds and performance would take a hit as a result; either way, that's a little too high to allow for passively cooled designs.
Last but not the least, the AMD Ryzen 5 3550H is built with a 12 nm process for lower-than-average, as of mid 2023, energy efficiency.
