Intel Core Ultra 9 275HX Laptop CPU Benchmark/Review. Intel did it!
Guys, One of the biggest problems with the i9-14900HX was power consumption. It was literally a desktop HX chip, repurposed for laptops.
Intel's new 275HX is a separate chip from the desktops, built specifically for high performance laptops. Built on TSMCs First Gen 3nm Node (N3B) as compared to the predecessor's 10nm (Intel 7) node.
Max performance is about 15-20% faster. They did this while disabling hyper-threading.
The real game changer is efficiency. It only needs 70 to 80 Watts to match a 14900HX at 140 to 160 Watts. This is important as this is a wattage range that most gaming laptops can handle easily, even thinner/lighter ones like my Legion Slim 7 (2023) handles 80 to 85 Watts sustained.
I had an ASUS Strix G16 (14900HX) scoring about 1800 in Cinebench 2024 pulling 150 to 175W, The OMEN max can do 1800+ at 77 Watts.
It even beats AMD's Strix Halo in both performance and efficiency at under 80W, A full powered Strix Halo (120 Watts) will probably just match it in Perf/W
The only thing left is battery life. I was hoping for better battery life but it performed worse than last gen. Josh even concluded that battery life is dependent on the laptop (which is absolutely true) so we have to wait for more optimized laptops to come out.
Even Razers new blade with the Strix Point HX 370 only go 8 Hours with a 90wh battery, other HX 370 laptops were getting at least 10 to 12 hours. So it really depends on the laptop.
All that is left is to wait for reviews of the 9955HX3D CPU and 5070Ti GPU.
I've got a Legion Slim 7 4060 (AMD) and I'm content for now. I just need a new laptop that's thin/light, great battery life, decent performance, 12GB VRAM and OLED/Mini-LED.
I'm more excited for more efficient CPUs, better screens, hopefully better battery life (not while gaming but web browsing, video playback etc).
If Nvidia allowed OEMs to use 3GB GDDR7 Modules, the 5060/5070 could also get 12GB VRAM.
Thus a Legion 7i 2025 (275HX) OLED...or...Yoga Pro 9i Mini-LED (Core Ultra H) with a 5070 12GB would be a great options.
Either that or the new Razer blade 16 (HX 370), which can do 145W on the GPU, that's enough to max out the 5070Ti.
Overall, it seems we are getting more efficient CPUs this year, either from Intel HX, AMD HX3D, Strix Point, Strix Halo etc. Better performance in CPU Bound Scenarios, better 1% lows.
Not a reason to upgrade if you already have a good laptop but it's nice to know all current gen choices are at least more efficient.
