AMD Introduces Ryzen 9000 Processors for Desktop, Zen 5 Steals Spotlight at Computex 2024

Computex Taipei

During AMD’s Computex 2024 kick-off keynote, Dr. Lisa Su, CEO of AMD, took the stage to unveil the highly anticipated next generation of Ryzen processors. The Ryzen 9000 series, powered by the Zen 5 microarchitecture, promises to bring significant advancements over its predecessor, Zen 4, and the Ryzen 7000 series. Set to launch in July 2024, these desktop processors are expected to deliver impressive performance and improved features.

AMD introduced four new chip SKUs based on the Zen 5 microarchitecture. The flagship model, the AMD Ryzen 9 9950X processor, boasts an impressive 16 CPU cores and a maximum boost frequency of 5.7 GHz. Alongside this powerhouse, AMD launched 6, 8, and 12 core parts, offering users a range of options in terms of core and thread counts. All four chips belong to the X-series lineup, meaning they come with unlocked multipliers and higher TDPs/clockspeeds.

In terms of performance, AMD claims an average IPC increase of 16% for Zen 5 in desktop workloads compared to Zen 4. With similar turbo clockspeeds to the Ryzen 7000 series, users can expect comparable performance from the new chips.

The Ryzen 9000 series will be compatible with the AM5 socket, which was introduced with the Ryzen 7000 series. This demonstrates AMD’s commitment to platform longevity. Accompanying the Ryzen 9000 series are two new high-performance chipsets: the X870E (Extreme) and the regular X870. While specific motherboard features are still under wraps, we do know that USB 4.0 ports will be standard on both chipsets, along with PCIe 5.0 support for graphics and NVMe storage. Additionally, higher AMD EXPO memory profile support is expected compared to previous generations.

Zen 5 represents AMD’s latest breakthrough in Ryzen microarchitecture. Although technical details are scarce, we do know some of the exciting new features it brings to the table.

Looking at the architectural differences between Zen 4, Zen 3, and Zen 5, we can confirm that AMD has adopted a new manufacturing process for its Ryzen 9000 desktop chips. While there has been speculation about Zen 5 being built on TSMC’s N3 (3 nm) nodes, our sources indicate that the Zen 5 CCD will be fabbed on TSMC N4. However, official confirmation is still pending. Notably, AMD’s mobile counterpart, the Ryzen AI 300 series, will be produced on a more advanced 4nm node.

Although AMD did not provide an in-depth analysis of the Zen 5 architecture at Computex, they did highlight some of the major improvements over Zen 4. These include an enhanced branch predictor for improved accuracy and efficiency, wider pipelines and SIMDs for higher throughput and faster data processing, and a larger out-of-order instruction window size for better parallelism and simultaneous instruction handling.

Zen 5 also introduces doubled resources and performance in certain areas. For instance, L2 to L1 memory bandwidth receives a significant boost, resulting in faster data transfers within CPU cores. AMD also claims better AI performance in inferencing and AVX-512 workloads. Notably, Zen 5 now features a full 512-bit wide SIMD for processing AVX-512 instructions.

Collectively, these enhancements aim to deliver substantial performance gains over Zen 4. AMD claims an average IPC uplift of 16% in desktop workloads. However, it’s important to note that specific benchmarks heavily influenced by AVX-512 instructions may see more significant improvements.

The Ryzen 9000 series chips consist of two core complex dies (CCDs) and a central I/O die (IOD). Each CCD contains 8 CPU cores, and the number of CCDs depends on the SKU. The Zen 5 CCDs are manufactured using TSMC’s 4nm process. The IOD, which handles I/O and memory operations, is expected to be similar or identical to the one used in the Ryzen 7000 series, based on TSMC’s N6 process.

Memory support for the Ryzen 9000 series remains consistent with its predecessors, utilizing DDR5. However, AMD promises faster EXPO memory profiles with the new X870E and X870 chipsets. While specific JEDEC memory specifications for the Ryzen 9000 SKUs have not been disclosed, more information is expected before the July 2024 launch.

AMD has also launched the specifications for the Ryzen 9000 series processors. The flagship Ryzen 9 9950X features 16 cores, a base frequency of 4.3GHz, a maximum boost frequency of 5.7GHz, and a 170W TDP. The Ryzen 9 9900X offers 12 cores, a base frequency of 4.4GHz, a maximum boost frequency of
