Quoteas the Radeon 8060S iGPU of AMD Strix Halo APUs falls between the RTX 4060 laptop and the RTX 4070 laptop GPUs.
Not according to 3dmark.com/search:
- 8060S: "Average score: 10013"
- 4060 (notebook): "Average score: 10511"
- 4070 (notebook): "Average score: 12537"
QuoteHowever, Intel has not, to our knowledge, claimed RTX 4060 or RTX 4070 laptop-level performance for the Arc B390 iGPU. Instead, the company has only claimed performance similar to the RTX 4050 laptop GPU.
Exactly. Strix Point is a 256-bit (quad-channel / 4*64-bit per channel), 256 GB/s, APU, while Panther Lake is a 128-bit¹ (dual-channel / 2*64-bit per channel) APU, so it's unsurprising.
Panther Lake: 153.6 GB/s = 128-bit * 9600 MT/s / 1000 / 8.
Strix Halo: 256 GB/s = 256-bit * 8000 MT/s / 1000 / 8.
So, Strix Halo has a 66% higher memory bandwidth.
But if Intel prioritizes the iGPU performance (which I hope they do, because I'm a gamer), it may come closer in gaming performance to Strix Halo, than what Strix Halo' 66% advantage would suggest.

Otherwise, use the Intel® UHD brand.
QuoteWe must remind you here that Strix Halo APUs aren't exactly cheap either. For instance, the Asus ROG Flow Z13 with the Ryzen AI Max+ 395, which AMD recently used as a comparison device against the Apple MacBook Pro 14, has a list price of $2,299.99 on Amazon.
Strix Halo being 256-bit wide makes it unsurprisingly bigger and thus more expensive.
QuoteWe'll have to wait and see for ourselves how well the Core Ultra X9 388H stacks up against the Ryzen AI Max+ APUs, and if AMD's current strategy is a good one.
Independent benchmarks at 28 January. Make sure to test the energy efficiency.
