Intel's Panther Lake "Arc B390" iGPU benchmarks have leaked again, this time showcasing impressive figures against the last-gen.
Intel Panther Lake "Arc B390" iGPU Showcases Its 12 Xe Core Strength, Should Make for Great Gaming Handhelds
The first Intel Panther Lake handheld has leaked out, confirming that Intel has already supplied its next-gen Core Ultra Series 3 chips to handheld manufacturers. While we only got a tease through the newest Geekbench leak, we also have the latest benchmarks for the Panther Lake 12Xe3 iGPU, the Arc B390, and it looks highly impressive.
Intel's Arc B300 iGPUs for Panther Lake "Core Ultra Series 3" CPUs will come in various configurations. We have already seen reports of four SKUs: the Arc B390, Arc B380, Arc B370, and Arc B360. The flagship is also the one that has been tested on multiple occasions, and there are also reports of superb figures in 3DMark. These SKUs range from 2, 4, 10, up to 12 Xe3 cores, each based on the latest Xe3 graphics architecture.
Today's performance leak comes from within PassMark, where the Intel Arc B390 has flexed its muscles to score 9453 points in the graphics benchmark suite.
Passmark Graphics (Higher is Better)
For comparison, the Intel Arc 140V with 8Xe2 iGPU cores scores 5173 points while the Arc 140T with 8 Xe+ iGPU cores scores 5635 points. That's an 83% and 67% improvement, respectively. Even versus the discrete Arc A380 GPU, the B390 iGPU scores a 50% lead. This is very impressive.
Next up, we compare the performance against the Radeon iGPUs. Versus the Radeon 890M, which is by far the fastest RDNA 3.5 iGPU around for the standard "Strix Point" 28-45W SKUs, the Arc B390 iGPU is 16% ahead. AMD is also readying a faster 3.1 GHz clocked Radeon 890M iGPU for its "Gorgon" Ryzen AI 400 series, and that should deliver a slight boost, but we expect the Arc B390 to remain ahead.
Compared to discrete GPUs, the Intel Arc B390 is faster than the Arc A530M. The fun fact about the A530M is that it has the same number of Xe cores as the B390, at 12, but based on the older Alchemist architecture. The B390 leads by 18%, and is also comparable to the Radeon 7600M dGPU.
The RTX 3050 sits a bit ahead, but this level of graphics performance should pose a serious threat to entry-level discrete offerings, especially when B390's Xe3 architecture has the latest features onboard, such as XeSS 3 MFG.
We should also make it clear that these benchmarks seem to undermine the performance of Intel's Xe2 architecture. The Arc 140V is shown much slower than the Radeon 890M, but in reality, it ends up close to or faster in actual games. So it looks like this benchmark suite is not optimized for older Arc GPUs, but the new Arc Xe3 architecture is doing well, and we can see further improvement once the finalized drivers roll out.
Given that Intel's Panther Lake CPUs are designed for highly efficient platforms, they will make a great choice for gaming handhelds. The power of Xe3 with XeSS 3 MFG and strong driver support will bring awesome performance in your hands.
