Gaming: Intel's New High-end Mobile Chip Is An Impressive Game-cruncher,...

Fast, feisty, fabulous. That's how I described the Intel Core Ultra X9 388H in my review, and I stand by it. It's got an Arc B390 iGPU that crushes all the others we've tested for gaming performance, and that's a remarkable technical achievement given the size of the graphics tile relative to the rest of the chip.

But there's a significant caveat hanging over the Intel Arc B390, and it goes like this: it's very, very quick—for an iGPU. Sure, it's capable of delivering gaming laptop-like performance, but compare it to any discrete mobile GPU of the current generation and the little graphics tile's limits are quickly revealed.

Now, none of this is meant to cast shade upon the considerable achievement of Intel's engineers. No one was expecting its new mobile graphics hardware to compete with, say, anything from the RTX 50-series.

In fact, Intel claims the Core Ultra X9 388H is 10% faster at gaming (on average) than a lappy with an RTX 4050 mobile. And, if you squint closely at those claims, you'll see that they were made in reference to a 60 W gaming laptop, with '2x upscaling' enabled.

Again, that's still fairly impressive for an iGPU, particularly as the Core Ultra X9 388H machine was claimed to be using 45 W for the whole shebang during those tests. But in reality, a low-wattage RTX 4050 mobile isn't particularly quick by modern standards.

And if you up the GPU wattage to something you might find in a regular entry-level machine (75 W, in the case of our Acer Nitro V 15 test laptop), Nvidia's last-gen lowest-tier graphics hardware pulls significantly ahead in most of our benchmarks.

We don't include frame generation in our iGPU test suite, but we do run the numbers again with Quality upscaling enabled. And yes, the Intel iGPU is remarkably quick compared to its direct competition, particularly with some XeSS enhancement. But stick it up against a budget, previous-gen gaming laptop with a half-decent dose of juice, and it does have a tendency to come unstuck.

Again, this isn't to cast doubt against Intel's claims, nor do I aim to put too much of a dampener on all the excitement surrounding Panther Lake's performance. Believe me, I'm excited too. But it is important to view the Arc B390 iGPU in context. And it must be said, when compared to most modern mobile graphics chips, it's still off the pace for the most part.

But the advantages of gaining a genuine dose of graphics grunt in a single chip are, nonetheless, legion. It means that productivity-st
