Architecture Overview

The updated core architecture is impressive, beginning with significant enhancements to Branch Prediction. This feature has been improved to enable more accurate and quicker decision-making by the CPU, which contributes to smoother, faster performance across various tasks.

Another improvement is the enlargement of the Op-Cache and Instruction Retire Queue. This expansion allows quicker instruction execution and retirement, speeding up the overall workflow. Coupled with a larger Integer and Floating-Point (Int/FP) register file, these improvements contribute to more efficient data processing capabilities.

The architecture includes deeper buffers throughout the core for more optimal data flow and reduced latency. Additionally, Load/Store operations have been optimized for better memory access performance, improving the speed at which the CPU can handle data.

Regarding energy efficiency, the Threadripper 7000 series now supports more power-efficient AVX-512 instructions in the Floating-Point Unit. This inclusion makes it possible to perform complex mathematical computations with lower energy consumption, a critical consideration in today’s eco-conscious environment.

As for the cache hierarchy, the Threadripper 7000 series has a fast private 1MB L2 cache. This larger cache allows quicker data retrieval, reducing the CPU’s wait time. The architecture also supports more outstanding misses from L2 to L3 per core and from L3 to memory, improving the system’s tolerance for cache misses and enhancing performance.

The architecture takes a baseline from the “Zen 3” design, with an L3 cache shared among all the complex’s eight cores. This design choice aids in better resource allocation. L3 is filled from L2 victims, meaning that data evicted from the L2 cache moves to the L3 cache. Additionally, L2 tags are duplicated in L3, aiding in probe filtering and enabling faster cache transfers. These cache improvements collectively lead to a more responsive and efficient system.

Memory Capabilities

The memory architecture of the Threadripper 7000 series comes with robust capabilities, supporting 8-channel DDR5 memory with speeds up to DDR-5200. This allows for a peak theoretical bandwidth of 266GB/s, calculated using the formula 8 channels × 8 Bytes × 5.2 GT/s. It’s a highly versatile memory configuration with one DIMM per channel capability and support for Registered DIMMs (RDIMMs). Capacity options are flexible, scaling up to 2TB for WRX90 and 1TB for TRX50 on the Ryzen Threadripper 7000 series. The architecture also includes a read UECC retry capability for enhanced reliability.

What’s particularly interesting is that this memory setup offers high bandwidth and efficiency in both dual-rank and single-rank configurations on the Threadripper 7000 series. This allows optimal DRAM capacity and total cost of ownership (TCO) optimization. Moreover, various interleaving options (2-ch, 4-ch, 6-ch, 8-ch) offer a tradeoff between latency and bandwidth, meeting different system requirements. Systems, by default, are configured as NPS1 but can be customized for additional optimization with multiple memory nodes per socket (NPS).

I/O Capabilities

The Threadripper 7000 series shows promise in its I/O capabilities as well. The design allows for die-to-die connectivity with up to 12 CCDs, featuring a refined IOD/CCD and package co-design. The improved Die-to-Die chiplet interface offers power efficiency, consuming less than 2pJ per bit with additional usage-based power reductions. Bandwidth capabilities are impressive, going up to 36Gbps and featuring up to 2x probe throughput compared to the 5000 Series.

Further enhancing its I/O capabilities, the Threadripper 7000 series supports up to 128 lanes per socket with PCIe Gen5 and eight bonus lanes of Gen3. This leads to very high I/O connectivity and offers over 90 percent higher peak (per slot) I/O bandwidth than the 5000 Series. This comes in addition to a combination of PCIe and SATA SERDES, allowing for up to nine PCIe devices per x16, for example, x8 + 8×1 configurations.

Conclusion

The AMD Ryzen Threadripper 7000 WX-Series is a powerful entrant to the HEDT market. With an impressive range of specs and the performance metrics to back it up, it sets new benchmarks for what a desktop processor can achieve. Combining these with the memory and I/O features, the Threadripper 7000 series presents an extraordinarily versatile and powerful platform capable of handling a broad range of high-performance computing tasks. Whether you’re into high-performance computing, content creation, or 3D rendering, these processors are built to deliver, and the new CPUs from AMD have you covered.

It’s worth mentioning that the performance of the AMD 7995WX outperformed the 96-core Genoa server-class processor in our tests. This outcome is expected, considering the 7995WX is explicitly designed for workstation applications and benefits from refinements over the server-class Genoa part. These refinements optimize it for the unique demands of high-end professional use cases. We are highly optimistic about the capabilities of this new CPU from AMD and look forward to a more comprehensive evaluation once we have a system in our lab. With systems coming from the usual suspects like Dell, HP and Lenovo, it shouldn’t be long until we can get a deeper hands-on look at these CPUs.
