AMD Ryzen AI 9 HX 470 vs Intel Core Ultra X9 378H: Comparison
What is the difference between AMD Ryzen AI 9 HX 470 and Intel Core Ultra X9 378H?
These two are close on paper, and total cores is the only measure that separates them at all: AMD Ryzen AI 9 HX 470 12 against Intel Core Ultra X9 378H 16. AMD Ryzen AI 9 HX 470 also leads on l3 cache, 24 MB on the AMD Ryzen AI 9 HX 470 versus 18 MB on the Intel Core Ultra X9 378H.
Which should you buy, AMD Ryzen AI 9 HX 470 or Intel Core Ultra X9 378H?
The AMD Ryzen AI 9 HX 470 is the one to take for copilot+ and on-device AI work, with a 55 TOPS NPU. The same goes for laptops needing 12 cores, 24 threads and a boost clock up to 5.2 GHz. It is the wrong buy for buyers wanting a socketed or upgradeable CPU, because it is soldered only. The Intel Core Ultra X9 378H suits premium thin laptops for creators and students in demanding courses and gaming and creative work on integrated Arc B390 graphics, though it is not built for budget buyers who mainly browse and use office apps and high-refresh AAA gaming, where a dedicated GPU is still faster. It is equally the pick for copilot+ PC and on-device AI features with a 50 TOPS NPU.
Where the two are identical
The common ground is wider than the gap: performance cores, integrated graphics, form factor, release year and market segment are identical here. They match on 2 further specifications as well.
Do the AMD Ryzen AI 9 HX 470 and Intel Core Ultra X9 378H differ on efficiency cores?
Yes. Efficiency Cores reads 8 on the AMD Ryzen AI 9 HX 470 versus 12 on the Intel Core Ultra X9 378H.
Is the Memory Channels the same on the AMD Ryzen AI 9 HX 470 and Intel Core Ultra X9 378H?
It is. Both are listed at 2, so it is not a reason to pick one over the other.
