Specification	Lenovo Legion 7i Gen 10 (16IAX10, 83KY000TCF)	Razer Blade 14 (2025) RTX 5070
Release year	2025	2025
Processor	Intel Core Ultra 7 255HX; 20 cores (8 performance + 12 efficiency), 20 threads, up to 5.2 GHz, 30 MB Intel Smart Cache This configuration also includes the Intel AI Boost NPU rated at up to 13 TOPS; the NPU is designed to run AI tasks at lower power than the graphics card. Lenovo	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 5060 Laptop GPU, 8 GB GDDR7; 2497 MHz boost, 115 W TGP, 572 AI TOPS TGP is the power limit the graphics chip can use in this laptop; the same GPU runs slower in lower-powered chassis. The graphics chip is soldered and cannot be replaced. Lenovo also offers the RTX 5070 Laptop GPU in this chassis at 115 W. Lenovo	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
Display	16-inch WQXGA (2560 × 1600) OLED, 16:10; 165 Hz, 500 nits typical / 1100 nits HDR peak, 100% DCI-P3, 1,000,000:1 contrast, glossy surface, DisplayHDR True Black 1000, Dolby Vision, G-SYNC 165 Hz means the panel can show up to 165 frames per second; G-SYNC matches the refresh to the GPU’s frame rate to reduce tearing. 1100 nits is a peak value for small areas in HDR content; everyday SDR brightness is 500 nits. The panel is factory-calibrated with X-Rite and is not a touchscreen. Lenovo	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	32 GB (2 × 16 GB) DDR5-5600 SO-DIMM; 2 slots, dual-channel Memory is not soldered. The highest capacity Lenovo has tested for this platform is 32 GB; both slots are filled from the factory, so an upgrade means replacing the modules. Lenovo	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	1 TB M.2 2242 PCIe 4.0 x4 NVMe SSD; 2 × M.2 2280 PCIe 4.0 x4 slots The slots are 2280-length, so a second SSD can be added. PCIe 4.0 x4 offers a theoretical 8 GB/s of bandwidth; actual speed depends on the installed SSD. Lenovo	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
