AMD Ryzen 7040 series more details exposure: 20 PCI-Express Gen 4 lanes

A few days ago, AMD CEO Dr. Lisa Su released the Ryzen 7040 series code-named “Phoenix Point” during the CES 2023 keynote speech, which is a mobile processor based on the new generation Zen 4 architecture. It is manufactured using TSMC’s 4nm process, with a chip area of ​​178mm² and a transistor count of 25 billion.

According to TechPowerup, AMD’s Ryzen 7040 series does not support PCIe 5.0 like existing desktop products, but only supports PCIe 4.0, with a total of 20 PCI-Express Gen 4 lanes. It is quite different from the Ryzen 7045 series code-named “Dragon Range” and the desktop product code-named “Raphael”. This means that the Ryzen 7040 series offers a full PCIe 4.0 x16 lane for graphics cards, and one PCIe 4.0 x4 lane for M.2 NVMe SSDs.

In addition to supporting dual-channel DDR5 memory, the memory controller of the Ryzen 7040 series can also support LPDDR5/LPDDR5x, which can be used with DDR5-5600 or LPDDR5-7600. Interestingly, the maximum memory capacity has reached 256GB, which is double the 128GB of “Dragon Range” and “Raphael”.

This time AMD adopted the RDNA 3 architecture on the integrated graphics of the Ryzen 7040 series, of which Ryzen 9 and Ryzen 7 are Radeon 780M with 12 CUs and a frequency of 2.9 GHz. The Ryzen 5 is an 8-CU Radeon 760M clocked at 2.8 GHz. The GPU uses AMD’s latest Radiance display engine, supports DisplayPort 2.1 UHBR10 and HDMI 2.1, and natively supports single-cable 8K@60 Hz display output.  At the same time, it also has the latest VCN media engine, hardware accelerated AV1 encoding up to 4K@240 Hz 10 BPC and 4320p@175 Hz 8 BPC H.265, plus hardware accelerated decoding of MPEG2, VC1, VP9, ​​H.264, H.265 and AV1 for almost all standard resolutions/bit depths/frame counts.
