Architecture
The processors are engineered to provide an average Instruction Per Cycle (IPC) performance improvement of 16 percent over the previous Zen 4 architecture. This enhancement implies that the Zen 5 chips are designed to be 16 percent more efficient at the same clock speeds and core counts, contingent upon specific workloads. Unlike the incremental updates often seen between previous Zen iterations, AMD characterizes Zen 5 as a substantive leap forward from Zen 4. Several architectural improvements have been implemented to achieve this advancement. Among these, AMD has optimized the branch prediction accuracy and reduced its latency, for improving the processor's efficiency in predicting the direction of a branch instruction before it is confirmed. The company also enhanced the throughput capabilities by expanding the pipelines and vector sizes, which facilitates the handling of more data simultaneously and improves the core's parallel processing ability. Furthermore, Zen 5 processors are reported to have enlarged window sizes that allow for more instructions in the pipeline, enhancing the overall computational throughput.
In terms of data handling, AMD let us know that the Zen 5 architecture doubles the bandwidth for front-end instructions. This enhancement is also reflected in the increased data transfer rates between the L1 and L2 caches and from L1 cache to the floating-point (FP) unit, which should notably boost the processor's efficiency in handling complex computations and data-intensive tasks.
A significant area of improvement in the Zen 5 series is its AI processing capabilities. While the desktop variants of these processors do not include a dedicated Neural Processing Unit (NPU) for AI tasks—unlike their Ryzen AI laptop counterparts—AMD states that the AI performance on the Zen 5 desktop CPUs is expected to be double that of the Ryzen 7000 series based on Zen 4 architecture.
Zen 5 processors continue to support DDR5 memory, providing higher bandwidth and better power efficiency compared to DDR4. The integration of PCIe 5.0 lanes is also maintained, enhancing the potential for faster and more flexible system expansions. Although specific details on the number of available PCIe lanes in the Zen 5 CPUs were not disclosed, it is anticipated to be consistent with the previous Zen 4-based Ryzen 7000 series, which featured 28 PCIe 5.0 lanes. These lanes are typically allocated with 16 lanes dedicated to a video card, eight lanes to SSDs, and the remaining four lanes facilitating communication with the chipset.
Ryzen 7 5700XT and Ryzen 9 5900XT
AMD will also be adding two Series 5000XT processors, for an easy upgrade. two new AM4 CPUs—the Ryzen 9 5900XT and the Ryzen 7 5800XT. This introduction sees a reduction in the number of models compared to the Ryzen 3000XT series launched in 2020, while continuing to target similar enhancements. Both models boast a 105-watt TDP and a maximum boost speed of 4.8 GHz, aligning them with some of the top specifications from their predecessors. The Ryzen 9 5900XT diverges from expectations by combining a maximum boost clock similar to the Ryzen 9 5900X, yet adopting the core and cache count from the Ryzen 5950X. Although the name suggests it might be a 12-core processor, it is in fact a 16-core model. In contrast, the Ryzen 7 5800XT aligns with the top clock speeds among AM4 8-core CPUs, reaching up to 4.8 GHz. The Ryzen 9 5900XT will feature 16 cores and the Ryzen 7 5800XT will have 8 cores, both maintaining the same 105W TDP and leveraging the Zen3 architecture, based on the Vermeer silicon.
AMD 800-Series Chipset Update: Introducing X870 as the Successor to B650E
AMD also unveils its new 800-series chipset family, designed to enhance the capabilities of these cutting-edge processors. The 800-series will be spearheaded by the AMD X870E chipset, followed by the X870, with both set to launch simultaneously with the Ryzen 9000 series. Later additions will likely include the B850 and B840 chipsets, with the current A620 chipset continuing as the entry-level option. This series introduces a revised product segmentation strategy. Key distinctions in the 800-series begin with the high-end X870E and X870 chipsets. The X870E is a dual-chip solution incorporating two Promontory21 chipsets, supporting PCIe Gen5 x16 and at least one PCIe Gen5 SSD. X870 will feature a single Promontory21 chipset, offering similar PCIe Gen5 x16 support but differing in its downstream general-purpose PCIe lane configurations.
Though not yet announced you can expect for the mid-range sector, the B650E and B650 to be succeeded by the B850 and B840. The B850 will maintain a similar configuration to the X870 concerning downstream PCIe Gen 4 lanes and will include a Gen 5 x16 PEG slot, although it allows for optional Gen 5 or Gen 4 NVMe slots depending on the motherboard manufacturer’s choice. The B850, unlike its higher-tier counterparts, will not guarantee USB4 connectivity, though manufacturers can add discrete USB4 controllers. The B840 represents a new tier within the portfolio, lacking any form of PCIe Gen5 support and omitting CPU overclocking capabilities. It will, however, support memory overclocking and is expected to be compatible with AMD EXPO and manual memory adjustments. Its connectivity suite includes Gen 4 PCIe across both PEG and general-purpose lanes, positioning it as an upgrade from the A620 and similar to the older B550 in terms of feature set. Additional comparisons reveal that the previous X670E and X670 differ mainly in their PCIe capabilities, with the X670 limited to Gen 4 on the PEG slot while still supporting Gen 5 NVMe slots attached to the CPU. Both chipsets were dual-chip configurations, with the secondary chip enhancing the general-purpose PCIe lanes of the primary chip linked directly to the processor. The new X870E retains this dual-chip configuration but updates it to match PCIe Gen 4 general-purpose lane counts similar to those of the X870E.
