https://www.techpowerup.com/303022/amd-announces-ryzen-7040-phoenix-point-mobile-processor-4nm-zen-4-rdna3-xdna AMD today launched two distinct kinds of mobile processors, the Ryzen 7045 "Dragon Range" serves the 45 W H- and HX-segments of performance and enthusiast notebooks with CPU core counts of up to 16-core/32-thread; while the U-segment, P-segment, and a portion of the H-segment (ranges of 15 W, 28 W, and 35 W), will be led by the Ryzen 7040 "Phoenix Point." Unlike the "Dragon Range" MCM, "Phoenix Point" is a monolithic silicon built entirely on the TSMC 4 nm EUV foundry node, and introduces a wealth of process-level and system-level power-management features.
AMD "Phoenix Point" combines an 8-core/16-thread CPU based on the "Zen 4" microarchitecture, with a powerful iGPU based on the latest RDNA3 graphics architecture, and a feature-packed AI acceleration engine based on the XDNA architecture AMD built after the Xilinx acquisition. The CPU component is a fully-fledged "Zen 4" CCX, with 8 CPU cores featuring 1 MB of dedicated L2 cache per-core, and sharing a large 32 MB L3 cache. This is an increase from the previous generation "Rembrandt" and "Cezanne" dies that had a reduced 16 MB L3 shared among the eight "Zen 3" or "Zen 3+" CPU cores.
The iGPU is based on the RDNA3 graphics architecture, and "Phoenix Point" physically features 12 CUs (768 stream processors), and come with all of the architectural improvements AMD introduced with the Radeon RX 7000 series discrete GPUs. The SoC features a PCI-Express Gen 4 host interface, a dual-channel (4 sub-channel) DDR5 + LPDDR5 memory interface, and integrated USB4 controllers, besides an upgraded set of media-acceleration and display engines.
"Phoenix Point" introduces the world's first fully-accelerated AI inference engine integrated on an x86 processor silicon, with the introduction of the new XDNA architecture. AMD's new Xilinx IP was used to build this. Compared to GNA on Intel processors, XDNA provides four concurrent AI processing streams for multi-tasking AI workloads, with minimal utilization of the x86 cores or RDNA3 CUs for its processing stack. This is as specialized as the AI engine found in Apple's M2-series SoCs. AMD will leverage the XDNA engine for a variety of AI-accelerated tasks, including image processing. The company will release separate SDKs for developers to get started on XDNA ISA.
The Ryzen 7040 series comes in three models targeting the 35-45 W power segment. The lineup is led by the Ryzen 9 7940HS with an 8-core/16-thread CPU, 4.00 GHz base frequency, and 5.20 GHz boost. A notch below this is the Ryzen 7 7840HS, another 8-core/16-thread part, with 3.80 GHz base, and 5.10 GHz boost. The Ryzen 5 7640HS packs a 6-core/12-thread CPU, clock speeds of 4.30 GHz base with 5.00 GHz boost, and 38 MB total cache. The first laptops based on these processors will begin shipping in March 2023.
Some very powerful mobile processors with fast integrated graphics. I'm curious to see what the pricing will be.
