Intel is set to introduce a major upgrade in integrated graphics with its Razor Lake-AX processor, featuring up to 32 Xe3 GPU cores. This move marks a substantial leap forward from the current Arc B390, which powers Intel's PTL lineup, potentially offering nearly three times the performance.
The Razor Lake-AX will come in two configurations: a 16-core iGPU and a 32-core iGPU. Both variants are based on Intel's Xe3 graphics IP, currently seen in Panther Lake processors. This suggests a robust iGPU cluster that could significantly enhance gaming performance for laptops without discrete GPUs.
The GPU die is reported to measure around 162.84 mm², a considerable size for integrated graphics. This large footprint hints at advanced packaging techniques like EMIB and Foveros 3D, which are likely being used to interconnect various elements of the chip. Additionally, Intel is reportedly bringing back on-package memory with LPDDR5X or LPDDR6, despite earlier claims that Lunar Lake would be the last design with this feature.
One intriguing aspect is the potential manufacturing location for this massive chip. The large iGPU suggests a design that pushes the boundaries of current packaging technologies, which could influence production costs and availability. The processor is expected to feature a BGA-4326 package with 4,326 pins, similar to what Intel's Xeon CPUs typically use.
Intel had previously considered a 'Nova Lake-AX' SoC with 48 Xe3 cores paired with a 28-core CPU cluster, but this has been put on hold. The Razor Lake-AX is expected to debut in 2027, following the Nova Lake generation.
For gamers, this development could mean a significant improvement in integrated graphics performance, potentially bridging the gap between entry-level and mid-range discrete GPUs. The use of advanced packaging techniques like EMIB and Foveros 3D could also lead to better thermal management and power efficiency, which are crucial for maintaining performance in demanding games.
The return of on-package memory with LPDDR5X or LPDDR6 is a notable feature that could enhance both performance and bandwidth for the integrated graphics. This, combined with the substantial increase in GPU cores, positions the Razor Lake-AX as a compelling option for gamers looking for high-performance integrated graphics without the need for a discrete GPU.
