Intel has quietly added another CPU to its upcoming Panther Lake lineup, and it’s a curious one: the Intel Core Ultra X7 378H. On paper, it looks like it should be a step up from the Core Ultra X7 368H and a notch below the Core Ultra X9 388H. In reality, it’s essentially the same chip as the Ultra X7 368H—just aimed at a different market.
According to the specifications listed by Intel, the Core Ultra X7 378H matches the Core Ultra X7 368H across the board. That includes the same core and thread layout, the same clock speeds, the same cache, the same power range, and the same integrated graphics. If you were expecting higher performance or a meaningful spec bump, there isn’t one to be found.
So what’s different? The key change is positioning. The Core Ultra X7 378H does not support the embedded segment. In practical terms, that means it’s intended for consumer-focused laptops and mainstream platforms, while the Core Ultra X7 368H can also be used in embedded applications. For buyers, it’s less about performance and more about where Intel wants each model to appear.
As for the hardware details, the Core Ultra X7 378H is a 16-core, 16-thread processor built with a hybrid core configuration: 4 Performance cores (P-cores), 8 Efficiency cores (E-cores), and 4 Low Power Efficiency cores (LP E-cores). It can boost up to 5.0 GHz and includes 18 MB of L3 cache. Power targets are also the same as the X7 368H, with a 25W base power rating and up to 80W maximum turbo power.
Graphics are unchanged as well. The Ultra X7 378H includes Intel’s Arc B390 integrated GPU, featuring 12 Xe3 cores, matching the iGPU configuration found on the Ultra X7 368H.
In short, the Intel Core Ultra X7 378H appears to be a consumer-only alternative to an existing Panther Lake chip rather than a new performance tier. If it shows up in upcoming laptops, expect it to deliver the same overall CPU and iGPU capabilities as the Core Ultra X7 368H—just without the embedded-market support.
