Intel may have already started talking up its newer Core Ultra lineup, but it isn’t done with Arrow Lake HX yet. Fresh early retail listings suggest there’s at least one more high-performance laptop chip on the way: the Intel Core Ultra 7 251HX. While Intel hasn’t publicly confirmed full specs, the appearance of this processor in upcoming gaming laptops from Lenovo and MSI is giving enthusiasts an early look at what to expect in next-gen portable performance.
The Core Ultra 7 251HX shows up in product listings tied to Lenovo’s Legion 5i 2026, where it’s rated at 55W. That power class places it in the same general territory as Intel’s Core Ultra 7 255HX, an existing Arrow Lake HX chip known for a 20-core layout (8 Performance cores plus 12 Efficient cores). Because the new 251HX is positioned so close in power, it’s reasonable to think it could share a similar core setup. At the same time, there’s still uncertainty—Intel could also choose a different configuration, such as keeping 8 Performance cores while reducing the number of Efficient cores. For now, core counts remain unknown, but the 55W rating signals this CPU is aimed squarely at high-performance gaming and creator laptops.
MSI is also preparing systems built around the same processor. A listed version of the MSI Raider 16 HX (model B2WH-019FR) mentions the Core Ultra 7 251HX with a 2.9 GHz base clock. For comparison, the Core Ultra 7 255HX is commonly listed with a 2.4 GHz Performance-core base clock and boosts up to 5.2 GHz. That doesn’t automatically mean the 251HX will be faster overall—base clock behavior depends heavily on cooling limits and workload—but it does hint that Intel may be tuning this model differently, potentially with lower out-of-box boost behavior than the 255HX.
The CPU isn’t the only interesting part of these leaks. The Lenovo Legion 5i 2026 listing also references an NVIDIA GeForce RTX 5070 laptop GPU with 12GB of VRAM, paired with a 115W power rating. That’s notable because the commonly discussed RTX 5070 mobile configuration is typically associated with less memory, and 12GB would represent a meaningful jump—especially for modern games, higher-resolution textures, and heavier creative workloads that can easily exceed lower VRAM limits.
If the 12GB RTX 5070 laptop GPU listing is accurate (and not an error), it could point to NVIDIA using 3GB GDDR7 memory modules to reach new capacities. That same approach could also open the door for other unusual VRAM sizes in the laptop stack, including the possibility of a GeForce RTX 5050 laptop GPU with 9GB of GDDR7 memory in the future.
For gamers and power users shopping the next wave of 2026 gaming laptops, these early listings are worth watching. A new Arrow Lake HX processor option like the Core Ultra 7 251HX could broaden performance and pricing tiers, while an RTX 5070 laptop GPU with 12GB VRAM—if confirmed—could be one of the more practical upgrades for real-world gaming longevity and memory-hungry workloads.
