Intel challenges AMD’s handheld dominance with new Arc G3 chips — Panther Lake silicon brings up to 14 cores, Arc B390 graphics to handhelds

After teasing the range earlier this year, Intel has officially revealed its Arc G3 range of chips designed for the best handheld gaming PCs. The Arc G3 range includes two SKUs, the Arc G3 and Arc G3 Extreme, that are built on Intel’s Core Ultra Series 3, or Panther Lake, silicon, and packing either the Arc B390 or Arc B370 integrated GPU, which are still the only two graphics processors on the market with Intel’s Xe3 architecture.

Intel has previously tried breaking into the handheld market with partner MSI, but it’s a space that’s been dominated by AMD’s Ryzen Z-series processors. Valve launched the Steam Deck with a custom AMD SoC, which was refined in the Steam Deck OLED, and both the ROG Ally X and Lenovo Legion Go S have stuck with Team Red. Intel’s G3 series looks like an attempt to establish Intel as a name in PC gaming handhelds, rather than just throwing laptop SKUs in the unique form factor as we’ve seen with devices like the MSI Claw.

Both chips use a 14-core CPU with 2 P-cores, 8 E-cores, and 4 LP E-cores. The main difference between them is the integrated GPU. The Arc B390 comes with 12 Xe3 cores while the Arc B370 comes with 10. Intel has yet to confirm clock speeds and power draw for the new range.

It has provided some other details, however. For starters, the G3 Extreme series will feature Intel Precompiled Shaders. AMD has recently partnered with Microsoft to provide something similar on desktop with Advanced Shader Delivery. The idea is that you download a precompiled set of shaders rather than compiling them at runtime, vastly reducing the time it takes to get into a game.

We’ve yet to see a true head-to-head battle between the Arc G3 and Ryzen Z ranges, but our testing of the B390 shows that it’s one impressive iGPU. Using high settings at 1080p with XeSS set to Balanced, we were able to achieve above 80 fps in Cyberpunk 2077. Mind you, that performance was inside a 16-inch Lenovo reference laptop. Expect lower performance inside a thermally-constrained handheld.

As with all recent Intel Arc graphics, Arc G3 chips come with full support for XeSS 3, including multi-frame generation, AI upscaling, and latency reduction. You’ll only be able to access those features in supported games, however. Unlike AMD, Intel doesn’t currently offer driver-level frame generation along the line of AMD Fluid Motion Frames (AFMF).

Intel says the chips will also arrive with Wi-Fi 7 R2, dual Bluetooth 6, and Thunderbolt 4. Partner systems from Acer, MSI, and OneXPlayer will start rolling out "in the coming months." Intel will be showing off several handhelds with the new Arc G3 range at Computex, and Tom's Hardware will have folks on the ground in Taipei to check them out in the flesh.
