AMD recently unveiled their highly anticipated Zen 5 CPU microarchitecture at Computex 2024. The announcement introduced two new client platforms using the latest Zen 5 cores: the AI PC-focused Ryzen AI 300 series for laptops and the Ryzen 9000 series for desktops, operating on the existing AM5 platform. Built around the new Zen 5 CPU microarchitecture, both series promise significant graphics and AI performance improvements.
The Ryzen AI 300 series is set to deliver enhancements thanks to the integration of the XDNA 2 NPU, offering up to 50 TOPS of performance. These mobile SoCs also feature upgraded RDNA 3.5 integrated graphics, providing better game performance than previous RDNA 3 mobile graphics. During AMD’s recent Tech Day, several technical details about Zen 5 were disclosed, highlighting its step up from Zen 4.
Central to this is the increased instructions per cycle (IPC), which continues AMD’s trend of incremental improvements from Zen to Zen 5.

Specifically, Zen 5 offers 16% better IPC than Zen 4.
Zen 5 brings a host of enhancements, including dual-pipe fetch and advanced branch prediction, enhanced instruction cache latency and bandwidth optimizations, improved integer execution capabilities, increased data bandwidth, and AI and vector processing with a full 512-bit AI datapath utilizing AVX-512. The Ryzen AI 9 HX 370 leads the mobile segment, which sports 12 Zen 5 cores with a max boost frequency of 5.1 GHz and a 24 MB L3 cache. The Ryzen AI 9 365, slightly less powerful, has 10 Zen 5 cores boosting up to 5.0 GHz, also with a 24 MB L3 cache.
Both models feature RDNA 3.5-based Radeon 890M integrated graphics, aiming to place these chips in high-performance notebooks with a TDP range of 15 to 54 watts. Gamespot says the Ryzen 9000 series for desktops, is set for launch on July 31st, and includes four X-series SKUs: the Ryzen 9 9950X with 16 cores, 5.7 GHz max boost clock, 80 MB of cache, and a 170W TDP; the Ryzen 9 9900X with 12 cores, 5.6 GHz max boost clock, 64 MB of L3 cache, and a 120W TDP; the Ryzen 7 9700X with 8 cores, 5.5 GHz max boost clock, 32 MB of L3 cache, and a 65W TDP; and the Ryzen 5 9600X with 6 cores, 5.4 GHz max boost clock, 32 MB of L3 cache, and a 65W TDP. The AMD Zen 5 microarchitecture heralds a new era of enhanced performance and AI capabilities for both mobile and desktop platforms.
With significant improvements across the board, AMD continues to push the envelope, setting new standards in processing power and efficiency.
