ASUS ROG Zephyrus G14 (2024) GA403UI / Lenovo Legion Pro 7 16IRX9H (83DE0005US)

24 MB is 8 MB of L2 plus 16 MB of L3 cache. The processor’s integrated Radeon 780M graphics handles light work when Advanced Optimus is active.

1655 MHz is the 1605 MHz boost clock plus a 50 MHz ASUS overclock. The 90 W ceiling is lower than RTX 4070 configurations in large 16–18-inch laptops and was chosen for the thin chassis. The GPU cannot be upgraded.

175 W is the highest total graphics power Lenovo allows in this model; going above NVIDIA’s 60–150 W base range for the RTX 4080 Laptop GPU relies on Dynamic Boost 2.0. The desktop RTX 4080 is a different product.

The MUX switch connects the internal display directly to the NVIDIA GPU; Advanced Optimus does this switch without a restart.

Each OLED pixel makes its own light, so blacks are fully dark; leaving static images on screen for long periods raises the risk of image retention.

DisplayHDR 400 is VESA’s entry-level HDR tier; it does not require local dimming, so HDR looks less striking than on OLED or Mini LED. 240 Hz and G-SYNC give smooth, tear-free motion in fast games. Lenovo notes that “IPS” may also cover similar panel types such as PLS, ADS and AHVA.

Memory cannot be increased later, so the amount should be chosen at purchase.

This configuration ships with a single module, so memory runs single-channel until a matching module is added to the second slot. Lenovo’s 32 GB limit is based on the modules it has tested.

There is a single M.2 slot, so more capacity means replacing the existing SSD with a larger one.

PCIe 4.0 x4 allows up to 8 GB/s in theory; real speed depends on the SSD. There is no card reader.

There is no wired Ethernet port; independent testing listed this and the lack of Wi-Fi 7 as drawbacks.

140 W charging over USB-C needs Lenovo’s own adapter; other adapters may deliver less. Up to four independent displays including the internal one are supported; Lenovo lists up to 4K/60 Hz for external outputs. Ethernet is 1 Gbit/s, not 2.5G, and supports Wake-on-LAN.

Independent testing found the Enter and arrow keys small.

On battery the GPU runs at a lower limit; full performance needs the 180 W adapter.

Lenovo says Super Rapid Charge reaches 30% in 10 minutes, 70% in 30 minutes and 100% in 80 minutes. 99.9 Wh sits just under the usual airline battery limit. Lenovo quotes 10.4 hours of 1080p video playback at 150 nits.

Liquid metal transfers heat between the chip and cooler more efficiently than standard paste, which makes servicing more delicate.
