SpecificationRazer Blade 14 (2025) RTX 5070ASUS ROG Zephyrus G14 (2024) GA403UI
Release year20252024
ProcessorAMD Ryzen AI 9 365 (10 cores / 20 threads, up to 5.0 GHz); 50 TOPS NPU

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

Razer		AMD Ryzen 9 8945HS (8 cores / 16 threads, 4.0 GHz, up to 5.2 GHz, 24 MB cache, 16 TOPS XDNA NPU)

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.

ASUS
GraphicsNVIDIA GeForce RTX 5070 Laptop GPU; 8 GB GDDR7; 100 W sustained TGP, 115 W with Dynamic Boost

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.

Razer		NVIDIA GeForce RTX 4070 Laptop GPU; 8 GB GDDR6; ROG Boost 1655 MHz; 90 W (65 W TGP + 25 W Dynamic Boost)

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.

ASUS
Display14-inch 3K (2880 × 1800) OLED, 16:10; 120 Hz; 0.2 ms response time; Calman Verified colour profiles

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.

Razer		14-inch 3K OLED; 2880 × 1800 (16:10); 120 Hz; 0.2 ms; 100% DCI-P3; G-Sync and Adaptive-Sync; anti-glare low-reflection (AGLR) surface; Pantone Validated

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.

ASUS
MemoryLPDDR5X 8000 MHz, up to 64 GB; soldered (cannot be upgraded later)

The Best Buy Canada configuration on this page has 32 GB; memory must be chosen at purchase.

Razer		32 GB LPDDR5X-6400 on board; not expandable

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

ASUS
StoragePCIe 4.0 NVMe SSD (up to 2 TB); single M.2 slot, upgradable to a single-sided drive up to 4 TB

There is no second SSD slot; upgrading replaces the existing drive. Double-sided M.2 drives may not fit the thin chassis.

Razer		1 TB PCIe 4.0 NVMe M.2 SSD; 1 × M.2 slot

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

ASUS
Ports2 × USB4 Type-C (PD 3.0, up to 100 W charging); 2 × USB 3.2 Gen 2 Type-A; HDMI 2.1; UHS-II microSD; 3.5 mm audio; security lock slot

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.

Razer		1 × USB4 Type-C (DisplayPort, Power Delivery, 40 Gb/s); 1 × USB 3.2 Gen 2 Type-C (DisplayPort); 2 × USB 3.2 Gen 2 Type-A; HDMI 2.1 FRL; microSD (UHS-II) card reader; 3.5 mm combo audio jack

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

ASUS
WirelessWi-Fi 7; Bluetooth 5.4 RazerWi-Fi 6E (tri-band, 2 × 2); Bluetooth 5.2 ASUS
CoolingVapor chamber, dual fans, thermal hood cover, 0.05 mm fins; Honeywell PTM7958 thermal gel

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

Battery and charging72 Wh; about 50% in 30 minutes with the 200 W adapter; Battery Health Optimizer in Synapse

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.

GPU switching—MUX Switch and NVIDIA Advanced Optimus

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