Intel Nova Lake: Possible Desktop CPU with 12-Core Xe3P iGPU to Challenge AMD APU

Rumors regarding the next generation of Core Ultra CPUs, codenamed Nova Lake, show no signs of slowing down. Following the fairly comprehensive leak from the past hours, which outlined the main features of Intel's future offerings, new whispers focus on the company's alleged intention to bring high-performance iGPU-equipped processor models to desktop PCs.

The company from Santa Clara is reportedly developing a specific variant with a much more powerful integrated GPU than what has been anticipated for the rest of the lineup or what has been done in the past, following in AMD's footsteps with desktop APUs (G-series), Ryzen processor models derived from the notebook segment, equipped with integrated graphics capable of running typical titles at 1080p with medium settings.

Preliminary information suggests that most Nova Lake-S CPUs will offer a basic graphics solution based on only 2 Xe3 cores, in line with what has already been seen in recent desktop platforms. However, one SKU might stand out due to the integration of 12 graphics cores based on the Xe3P architecture, an advanced and optimized version of Xe3. This configuration would pair with a CPU composed of 4 P-cores, 8 E-cores, and 4 LP-E cores, totaling 16 cores and 16 threads. Thus, it would be a mid-range model in the Nova Lake lineup, which, according to rumors, could reach up to 52 cores in the high-end variants.

The most significant aspect concerns the graphical component. The Xe3P cores represent an evolution of the Xe3 architecture, with expected improvements in efficiency and performance. Some unofficial estimates suggest an increase of between 20% and 30% compared to the previous generation, although concrete data is currently lacking.

A useful reference comes from the Panther Lake family (Core Ultra 300), where configurations with 12 Xe3 cores have already shown interesting performance, close to low-end discrete GPUs. With Xe3P and wider thermal margins on desktop, the new solution could push further.

At the base of this alleged evolution in Intel's lineup is the tiled architecture. The modular design allows for the combination of different CPU and GPU blocks within the same package, making it possible to reuse components already developed for the mobile market.

The introduction of such a powerful integrated GPU could entail specific requirements on the platform side. There are discussions around the need for dedicated VRM phases (VCCGT) on motherboards, a factor that could limit the full utilization of these SKUs to higher-end platforms.

Another key factor will be memory bandwidth: Nova Lake will support faster DDR5 modules (8000 MT/s), but their cost could affect overall affordability. The adoption of larger cache sizes could help mitigate bottlenecks, improving the performance of the iGPU.

It remains to be seen whether this variant will indeed see the light and with what definitive characteristics. Nevertheless, the rumors outline a potentially significant evolution in the role of integrated GPUs in the desktop segment, with implications for the competitive balance between Intel and AMD.
