Intel is preparing to revolutionize mobile computing with its next-generation Panther Lake processors, whose integrated graphics performance has shown an extraordinary leap according to recent benchmark leaks. The company's Arc B390 integrated GPU has demonstrated nearly double the performance of its predecessor in synthetic tests, potentially changing what users can expect from slim laptops without dedicated graphics cards.
Benchmark Results Reveal Stunning Performance
Leaked 3DMark Time Spy benchmark tests reveal that the Intel Arc B390 integrated GPU has achieved an impressive score of over 7,000 points. This represents a dramatic improvement over Intel's previous generation Arc 140T GPU found in Arrow Lake-H chips, which it outperforms by nearly 100%. The score also significantly surpasses AMD's competing RDNA 3.5-based Radeon 890M integrated GPU, which managed approximately 3,374 points in the same test.
Even more remarkably, the Arc B390's benchmark performance exceeds that of Nvidia's desktop GeForce RTX 3050 GPU, which scores 6,323 points in identical testing conditions. This achievement is particularly significant because it positions an integrated graphics solution ahead of a dedicated desktop gaming GPU, something previously unheard of in the industry.
Technical Specifications and Launch Timeline
The powerful Arc B390 integrated GPU comes equipped with 12 Xe3 cores, representing the next evolution of Intel's graphics architecture. Intel has scheduled the official launch of both the Panther Lake CPUs and their integrated graphics for January 2026, with expectations building for a comprehensive unveiling at CES 2026 in early January.
These leaked results validate Intel's earlier promise that Panther Lake's new Arc B390 GPU would deliver more than 50% faster graphics performance compared to the previous generation. The actual performance appears to have exceeded even these ambitious claims, with the nearly 100% improvement demonstrated in the benchmarks.
Implications for Mobile Gaming and Content Creation
While synthetic benchmarks like 3DMark don't always perfectly reflect real-world gaming performance, the substantial jump in scores indicates that the Arc B390 could enable significantly better gaming experiences on slim and light laptops powered by Panther Lake processors. This combination of power efficiency and performance makes Intel's new integrated GPU a strong competitor in the high-end mobile gaming segment, traditionally dominated by discrete GPUs.
The technology promises to bring desktop-level gaming capabilities to portable devices without the bulk, heat, and battery life compromises typically associated with dedicated graphics cards. For Indian consumers and professionals who rely on laptops for both work and entertainment, this development could eliminate the need to choose between portability and performance.
Industry observers are eagerly awaiting the official unveiling of Panther Lake and the Arc B390 iGPU at CES 2026, where more comprehensive benchmarks and real-world gaming tests will provide a clearer picture of its capabilities. For now, these leaked 3DMark scores establish the Intel Arc B390 as a serious rival to mid-range discrete GPUs and represent one of the most significant leaps forward in integrated graphics technology in recent years.
