Intel Core i5-12450H vs AMD Ryzen 5 3550H vs AMD Ryzen 5 3580U
Intel Core i5-12450H
► remove from comparison
The Intel Core i5-12450H is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 4 of the 6 performance cores (P-cores, Golden Cove architecture) and 4 of the 8 efficient cores (E-cores, Gracemont architecture) leading to 8 cores in total (octa core CPU). The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The clock rate ranges from 2 to 4.4 GHz on the performance cluster and 1.5 to 3.3 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 12 MB L3 cache. Compared to the 12500H, the 12450H offers less E-cores, lower clock rates, a slower iGPU and no vPro support.
Performance
The average 12450H in our extensive database is a bit of a disappointment, its multi-thread benchmark scores only just matching those of the Ryzen 7 5700U and the Core i7-10750H, both fairly old chips as of Q2 2023.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Features
The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).
The integrated graphics adapter is based on the Xe-architecture and offers 48 of the 96 EUs (Execution Units) operating at up to 1.2 GHz.
The CPU is rated at 45 W base power (95 W PL2) but most laptops will use a PL1 of around 60 Watt. The SoC is manufactured in a 10nm process at Intel, which is known as Intel 7.
AMD Ryzen 5 3550H
► remove from comparison
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.
AMD Ryzen 5 3580U
► remove from comparisonThe AMD Ryzen 5 3580U, a Microsoft Surface Edition chip, is a mobile SoC that was announced in October 2019 as part of the Surface Book 15. It combines four Zen+ cores (8 threads) clocked at 2.2 - 3.8 GHz with a Radeon RX Vega 9 graphics adapter with 9 CUs (576 Shaders) clocked at up to 1300 MHz. Compared to the similar Ryzen 5 3500U, the 3580 integrates a faster GPU with 9 instead of 8 CUs.
The Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements. Furthermore, the 12nm process allows higher clock rates at similar power consumptions.
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 3580U in our extensive database is in the same league as the Core i5-1035G7 and also the Core i7-10510U, as far as multi-thread benchmark scores are concerned. This is a fairly decent result, as of mid 2021.
Power consumption
This Ryzen 5 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers - or should we say, Microsoft - are allowed to change to anything between 12 W and 35 W with clock speeds and performance changing correspondingly. Those values are not low enough to allow for fan-free designs, for better or worse.
The CPU is built with a fairly old, as of late 2022, 12 nm process for lower-than-average energy efficiency.
