Specification	ASUS ROG Strix SCAR 18 (2025) G835LX	Razer Blade 14 (2025) RTX 5070
Release year	2025	2025
Processor	Intel Core Ultra 9 275HX (24 cores / 24 threads, up to 5.4 GHz, 36 MB cache, 13 TOPS NPU) The cores are a mix of performance and efficiency cores; there is no Hyper-Threading, so core and thread counts are equal. ASUS	AMD 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
Graphics	NVIDIA GeForce RTX 5090 Laptop GPU; 24 GB GDDR7; ROG Boost 1647 MHz; 175 W (150 W TGP + 25 W Dynamic Boost) 1647 MHz is the 1597 MHz boost clock plus a 50 MHz ASUS overclock. 175 W is the highest total graphics power; the 25 W Dynamic Boost share moves to the GPU when CPU load is low. The GPU is soldered and cannot be upgraded. ASUS	NVIDIA 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
GPU switching	MUX Switch and NVIDIA Advanced Optimus The MUX switch connects the internal display directly to the NVIDIA GPU to reduce latency in games; Advanced Optimus does this switch without a restart. ASUS	—
Display	18-inch ROG Nebula HDR Mini LED; 2560 × 1600 (16:10); 240 Hz; 100% DCI-P3; G-Sync; anti-glare low-reflection (AGLR) surface; Pantone Validated The Mini LED backlight dims in many small zones independently, which keeps dark areas dark in HDR content; it is not as precise as pixel-level OLED control. ASUS	14-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
Memory	64 GB (2 × 32 GB) DDR5-5600 SO-DIMM; 2 slots; up to 64 GB Both slots are filled in this variant and ASUS’s stated maximum is already reached; an upgrade means replacing the modules. ASUS	LPDDR5X 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
Storage	2 TB + 2 TB PCIe 4.0 NVMe M.2 SSD, RAID 0; 2 × M.2 slots RAID 0 combines the two drives into one fast volume; if either drive fails all data can be lost, so regular backups matter. ASUS states that only single-sided SSDs are supported. ASUS	PCIe 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
Ports	2 × Thunderbolt 5 (USB-C; DisplayPort, Power Delivery, G-SYNC); 3 × USB 3.2 Gen 2 Type-A; HDMI 2.1 FRL; 2.5G LAN; 3.5 mm combo audio jack Thunderbolt 5 can offer up to 120 Gb/s in one direction, useful for fast external storage and high-resolution monitors. Independent testing criticised the lack of rear ports. ASUS	2 × 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.
