Intel has officially launched Panther Lake, and with it, its fastest iGPU to date, the Xe3-based Arc B390, which offers seriously good performance.
Intel Shows Arc B390 iGPU Gaming Benchmarks: Xe3 Crushes Radeon & Adreno iGPUs of the Same Class While Tackling Discrete RTX 4050 Graphics
Well, Arc lives on, and its biggest upgrade comes not in the form of a discrete graphics chip but an iGPU. But this isn't just any iGPU we are talking about; this is Intel's fastest integrated graphics solution to date, and oh boy is it a shocker.
When we initially saw the improvements discussed for its upcoming Xe3 architecture at the Tech Tour 2025, we kind of guessed that we were in for a treat with next-gen solutions that will employ it. So the first product to feature this new architecture is the Arc B-Series iGPUs, and the flagship B390 offers an impressive performance leap over its predecessors and competitors.
With 12 Xe3 cores on deck, a 50% improvement versus the previous fastest iGPU, the Arc 140V on Lunar Lake, the Arc B390 delivers a 77% improvement in graphics performance and a 76% improvement over the Xe+ based Arc 140T for Arrow Lake. The performance was measured using 2x upscaling across all of the tested iGPUs in the titles that supported upscaling at 1080p.
But what about native performance? Well, the Intel Core Ultra X9 388H with the Arc B390 iGPU was compared against the AMD Ryzen AI 9 HX 370 with the Radeon 890M iGPU and offered a 82% uplift. What's even better is that these are 1080p Native numbers across a wide selection of games, and the Ryzen chip was running at a sustained 53W power versus the 45W sustained power of the Core Ultra 3 chip.
When compared to the Adreno GPU on the Qualcomm Snapdragon X Elite 84-100 with a 50W sustained TDP, the Arc B390 dominates with a 2.6x lead. That's massive!
Intel is so proud of its Arc B390 iGPU that they even added discrete graphics to the comparison. The Arc B390 iGPU at the same 45W sustained TDP matches and sometimes even exceeds the performance of NVIDIA's RTX 4050 laptop GPU (60W Sustained TDP). It's 10% faster on average.
Intel also showcases the Frame-Gen and Multi-Frame Generation figures where the Arc B390 iGPU knocks the socks off of AMD's Radeon 890M iGPU and the NVIDIA RTX 4050 Laptop GPU in titles such as Battlefield 6 and Cyberpunk 2077. Once again, the Arc B-series iGPUs are the only ones on the market with support for MFG of up to 4x mode.
These numbers go on to show Intel's dedication to its graphics innovations, and with such faster iGPU designs, we can see entry-level iGPUs easily replacing entry-level discrete laptop GPUs such as the RTX 4050 and RTX 5050. Expect some amazing graphics performance and efficiency tests for handhelds that will feature these chips.
