AMD officials have updated the specification sheet for the Ryzen 7040 series “Phoenix Point” processor, detailing the processor’s I/O feature set. There are several details to be aware of, including PCIe-Express lanes, memory, and more.
Does not support PCIe-Express Gen 5
The Ryzen 7040 processor has a total of 20 PCI-Express Gen 4 lanes, all of which are “available” (that is, the 4 lanes that do not count as the chipset bus).
That means the chip has a full PCI-Express 4.0 x16 interface for a discrete graphics card and a PCI-Express 4.0 x4 for connecting to an M.2 NVMe slot.
For comparison, the client I/O dies in the “Raphael” desktop MCM and the “Dragon Range” mobile MCM provide a total of 28 Gen5 lanes (24 usable, with x16 PEG + two x4 for CPU-attached M.2 slot).
Memory
Another interesting thing about “Phoenix Point” is the type of memory. The processor has a dual-channel DDR5 memory interface, and also supports LPDDR5 and LPDDR5x.
The maximum memory speed is DDR5-5600 and LPDDR5-7600. What’s really interesting is that it supports up to 256GB of memory capacity, twice that of “Raphael” and “Dragon Range”. This bodes well for AMD’s eventual Socket AM5 APU based on the “Phoenix Point” chip design.
graphics card
The Ryzen 7040 series is equipped with the “Radeon 780M” processor, the new 780M is based on the latest RDNA3 graphics architecture, contains 12 compute units (768 stream processors), and has the same dual instruction issue rate capability as the desktop Radeon RX 7900 series GPU and the Matrix Math Accelerator, iGPU with an engine clock of up to 2.90 GHz.
Phoenix Point’s iGPU is confirmed to adopt AMD’s latest Radiance display engine, supports DisplayPort 2.1 UHBR10 and HDMI 2.1, and natively supports single-line 8K 60 Hz display. It also has the latest VCN media engine with hardware-accelerated AV1 encoding, up to Up to 4K @ 240 Hz 10 bpc, and 4320p @ 175 Hz 8 bpc H.265; and hardware-accelerated decoding of virtually all standard resolutions/bit depths/frames of MPEG2, VC1, VP9, H.264, H.265, and AV1 .
On TSMC’s 4nm EUV foundry node, the “Phoenix Point” monolithic silicon has a die area of 178 mm2 and a transistor count of 25 billion. In addition to the iGPU, it also has a single 8-core “Zen 4” CCX. Each of the 8 CPU cores has 1MB of dedicated L2 cache and shares 32MB of L3 cache.
