Intel Core 5 120U vs AMD Ryzen 7 7730U

Intel Core 5 120U

The Intel Core 5 120U is a mid-range notebook CPU based on the Raptor Lake-U Refresh (RPL-U) series (Alder Lake architecture), which was introduced in January 2024. The CPU offers 2 performance cores (P-cores, Golden Cove architecture) and 8 efficiency cores (E-cores, Gracemont architecture). The P-cores support hyperthreading (therefore 12 threads together) and clock from 1.4 to 5 GHz. The E-cores clock from 0.9 - 3.8 GHz and should offer comparable performance to old Skylake cores (e.g. i7-6300HQ). The C5 120U also supports vPro Essentials management features.

Performance

Due to the high clock rates, the performance is comparable to the old Core i7-1355U. As usual with Alder Lake, the performance is heavily dependent on the cooling and the TDP settings.

Graphics unit

Like its predecessor, Intel integrates an Intel Xe-based graphics unit in Alder Lake. 80 of the 96 EUs are activated on the 120U.

Features

Like Tiger Lake, Alder-Lake-P also has WiFi 6E and Thunderbolt 4 (4x) partially integrated. The integrated memory controller supports LPDDR5-6400 and the integrated Gaussian and Neural Accelerator (GNA) is installed in version 3.0. The Quick Sync 8 media engine is the same as in Rocket Lake and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC and AV1 decode. The chip still only supports PCIe 4.0 (x8 for GPU and two x4 for SSDs).

Power consumption

The Intel Core 5 120U is specified with 15 watts (PL1) TDP and 55 watts (PL2) max. turbo power. The processor is manufactured using the further improved Intel 7 process (10 nm SuperFin).

AMD Ryzen 7 7730U

The AMD Ryzen 7 7730U is a processor for thin and light laptops based on the Cezanne generation. It is part of the second "Barcelo" refresh in early 2023 and offers the same specifications as the old Ryzen 7 5825U. The CPU integrates all eight cores based on the Zen 3 microarchitecture clocked at 2 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in 7nm at TSMC.

The Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2 but stays behind the current Zen 4 based CPUs (e.g. 7040HS series).

Performance

The average 7730U in our database is in the same league as the Ryzen 7 5825U, Ryzen 7 6800U, Ryzen 7 PRO 6850U and also the Core i7-1360P, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 30 W, the ThinkPad E14 G5-21JSS05C00 is among the fastest laptops built around the 7730U that we know of. It can be almost 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 GPU with 8 CUs at up to 2000 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.

The TDP of the APU is specified at 15 Watt (the 5825U was specified at 10 - 25W).
