Razer Blade 14 (2025) RTX 5070 / Lenovo Legion Pro 7 16IRX9H (83DE0005US)

The NPU runs Copilot+ AI features at low power, separately from the CPU and GPU.

The RTX 5070 Laptop is the strongest option in the Blade 14; RTX 5060 Laptop versions are also sold. Dynamic Boost shifts 15 W of the power budget to the GPU when CPU load is low. G-Sync is enabled in the NVIDIA Control Panel.

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.

Ready profiles for Rec. 709, DCI-P3, sRGB and Adobe RGB lock the screen to that colour space for colour-critical work. 120 Hz is lower than the previous 240 Hz IPS, but OLED response is very fast.

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.

The Best Buy Canada configuration on this page has 32 GB; memory must 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 no second SSD slot; upgrading replaces the existing drive. Double-sided M.2 drives may not fit the thin chassis.

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

The USB4 ports also work with Thunderbolt 4 docks and accessories. 100 W USB-C charging needs a 20 V capable adapter and does not replace the 200 W adapter for gaming.

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.

The phase-change thermal gel is used to keep heat transfer between the chip and heatsink stable over time without drying out.

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

Battery Health Optimizer lowers the charge limit for always-plugged-in use to reduce long-term battery wear. Razer quotes up to 11 hours of battery life.

Snap Tap prioritises the most recent of two selected keys, speeding up direction changes in games.

Drops and spills are not covered by the standard warranty; RazerCare plans are sold separately.

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.
