Intel Unveils Core Ultra CPUs with Powerful On-Chip AI
Intel has launched its new Core Ultra 7 265K and Ultra 9 285K CPUs, which are positioned to compete directly with AMD's high-end Ryzen 9 processors. A key feature of the new chips is an integrated Neural Processing Unit (NPU) capable of up to 74 TOPS for on-device AI workloads. The upcoming Panther Lake generation is also expected to feature integrated graphics with performance approaching that of dedicated gaming consoles, potentially reducing the need for discrete GPUs in many embedded vision applications.
- The Core Ultra processors utilize a hybrid architecture with Performance-cores (P-cores) for demanding tasks and Efficiency-cores (E-cores) for background processes, a design refined from the earlier Alder Lake and Raptor Lake series. This is part of a larger "chiplet" or "tile-based" design where the processor is split into a Compute Tile, Graphics Tile, IO Tile, and SOC Tile, a move aimed at increasing efficiency and reducing costs. - To qualify as a "Copilot+ PC," Microsoft requires a Neural Processing Unit (NPU) capable of at least 40 trillion operations per second (TOPS). Intel's Lunar Lake mobile chips meet this with a 48 TOPS NPU, contributing to a total of 120 TOPS when combined with the GPU and CPU. - The upcoming Panther Lake architecture aims to merge the power efficiency of the "Lunar Lake" series with the high performance of the "Arrow Lake" series into a single platform. Intel claims Panther Lake can offer 50% more performance at similar power levels to Lunar Lake, or reduce power consumption by 30% for the same multi-threaded performance as Arrow Lake-H. - Recent benchmarks of Panther Lake's integrated graphics, specifically the ARC B390, have shown performance surpassing that of the Xbox Series S in certain tests. While it still falls short of the PlayStation 5's performance, this represents a significant leap for integrated graphics. - Intel's successor to Panther Lake, code-named "Nova Lake-S" (Core Ultra 400 series), is rumored to feature an NPU with a throughput of 74 TOPS, significantly exceeding the Copilot+ requirement. This generation is anticipated for release in late 2026 or early 2027. - The move to a tile-based architecture allows Intel to use different manufacturing processes for different components. For instance, the Lunar Lake architecture uses TSMC's N3B process for the compute tile and TSMC's N6 process for the platform controller tile. - Arrow Lake, a performance-focused predecessor to Panther Lake, introduced a chiplet design but without Hyper-Threading on its Performance-cores. Despite the lower thread count, Intel claimed increased multi-threaded performance. - The integrated GPU in Panther Lake, featuring the new Xe3 architecture, shows significant gains in AI workloads. In some benchmarks, its AI performance is comparable to entry-level discrete GPUs like Nvidia's RTX 5050 and 5060.
