![]() ![]() This is labelled Ryzen AI and is based on the XDNA architecture that comes from Xilinx technology portfolio. ![]() One of the main innovations (which you may not use much in practice however, at least not at first) of the Phoenix APU is a special dedicated unit for accelerating artificial intelligence (neural network) applications. AMD Ryzen 7040 is said to enable more than 30 hours of video playback on a single laptop charge (source: AMD) Ryzen AI There will probably be a number of different tweaks and improvements across the main blocks and physical implementation of the APU, but they haven’t been detailed anywhere yet. The Phoenix and Ryzen 7040 are also supposed to have various generational efficiency and power draw improvements, making the laptops capable of playing video for more than 30 hours on battery. For VP9, 8K decoding is supported, but not encoding (this is a good compromise, VP9 encode capability doesn’t really matter). The GPU also has an integrated video encoder and decoder capable of decoding as well as encoding 8K video (7680×4320) at 60 Hz in both HEVC and AV1 formats. With DisplayPort, this APU supports display resolutions up to 7680 × 4320 pixels at 60 Hz, 3840 × 2160 at 240 Hz, and FullHD at up to 600 frames per second (these maximums are reached via DSC compression). This graphics supports up to four monitors and HDMI 2.1 and DisplayPort 2.1 outputs, but with lower bandwidth than the Radeon RX 7900 (only UHBR10 mode with 38.7 Gbps bandwidth is supported).

Like the previous 6nm Rembrandt APU (Ryzen 6000), it has only 12 CUs (768 shaders), but it will reach very high clock speeds – the top model has a GPU boost clock of 3000 MHz in the specifications. This is followed by integrated graphics, which should be the most powerful iGPU on the PC platform. The blocks shown in the chip probably do not correspond to reality (source: AMD) The best integrated graphics in a PC to date Illustration showing the package and the Ryzen 7040 chip. The processors will also have slightly lower clock speeds due to the fact that there are only laptop processors in this series, for now. It is half the size of the desktop chiplet version, which will reduce performance in games. ![]() The main components of the Phoenix APU are eight Zen 4 cores in a single CCX block with 16MB 元 cache. ![]() The silicon is manufactured on a TSMC process and contains more than 25 billion transistors in a 178 mm² area (not so small a die for this advanced and expensive process). Phoenix is not yet a chiplet design like the desktop Ryzen 7000s, but a monolithic 4nm chip, which should be beneficial for power draw and power efficiency. The mobile Ryzens will be a jungle of five different chips in the 7000 generation as a whole, so it will be challenging to navigate them, but the 4nm Phoenix APUs with Zen 4 can be distinguished by a numerical designation ending in 40, with the four indicating the Zen 4 core (the low-end Mendocino with Zen 2 Lite cores will have a designation ending with 20, refreshed 6nm Rembrandt models will end with 35 and refreshed 7nm Barcelo/ Cezanne has a designation ending with 30). This mobile “APU” version of Zen 4 is officially designated as the Ryzen 7040 series. So it’s going to be a very interesting laptop platform. They are based on the all-new Phoenix APU, which is the first 4nm Ryzen chip and the first processor with an integrated RDNA 3 GPU, which will also clock up to 3 GHz. In addition to the AM5 Ryzen 7000 processors with 3D V-Cache and mainstream 65W TDP models, AMD also announced a wholly new offering at CES 2023: the first processors with Zen 4 architecture for laptops.
