Threadripper 2 Specs, Price, Topology, Die Arrangement, & More
# AMD Threadripper 2 CPUs: A Comprehensive Overview
## Introduction
AMD has once again pushed the boundaries of processor innovation with the release of their new **Threadripper 2** series. This video provides an in-depth look at the specs, architecture, and performance metrics of these powerful CPUs. While other outlets are focusing solely on the technical specifications and pricing, we aim to go beyond that by delving into the topology of how Threadripper 2 is arranged under its Integrally Heatsinked Substrate (IHS).

## The Configuration: What’s New in Threadripper 2?
The **2990 WX** stands out as the flagship halo product in AMD's lineup, featuring an impressive **32 cores and 64 threads**. This marks a significant improvement over its predecessor, as it now utilizes all four active dies, unlike previous Threadripper models that only used two of the four available dies.
For those familiar with the original Threadripper, this means that the other two dies are no longer just "deactivated" but are now fully integrated into the processor's architecture. This change has been a point of contention between AMD and enthusiasts like **Bauer**, who previously argued about the potential use of these deactivated dies.
Other notable models in the Threadripper 2 series include:
- The **2958 W** (or 2950 X), which replaces the existing **1950 X**.
- The **2970 WX**, a new addition to the lineup with **24 cores and 48 threads**.
- The **29:20**, a mid-range option with **12 cores and 24 threads**, priced at $650.

## Architecture and Topology
The Threadripper 2 series is built on AMD's **n+ architecture**, which focuses on improving cache latencies across all levels (L1, L2, and L3). Compared to the previous generation:
- **L3 cache latency has dropped by 15%**.
- **L2 cache latency has improved by 9%**.
- **L1 cache latency is up by 8%**.
Additionally, DRAM latency has been reduced by **2%**, with official JEDEC support now extending to **2933 MHz** (up from **2666 MHz**). This improvement in memory compatibility and performance will likely benefit users running production tasks like video editing or rendering.
The topology of Threadripper 2 is not drastically different from its predecessor, but it does include some key changes. For instance, the **2990 WX** features a more complex block diagram due to its additional dies. The two IO controllers are now connected via Infinity Fabric interconnects, while the other two dies are dedicated to processing tasks.

## Performance Metrics and Testing
AMD has conducted internal testing for Threadripper 2, focusing on gaming performance at **1080p**. Despite being primarily a workstation CPU, AMD chose to benchmark against Intel's similarly priced parts. The results showed a **6% decline in gaming performance compared to Intel**, which is surprisingly honest given the competitive nature of the market.
For production tasks like handbraking, Blender rendering, and Cinebench testing, Threadripper 2 holds its own due to its superior core count and thread count. AMD also emphasized that their testing suite was not skewed or manipulated to favor their product, which adds credibility to their claims.

## Thermal Considerations and Cooling
Thermal performance is always a concern with high-end CPUs, and Threadripper 2 is no exception. AMD has included an **H100 iCL closed-loop liquid cooler** for testing purposes. While this cooler is effective, it operates at relatively high fan speeds, which can be noisy.
For users looking to reduce noise levels, a **280mm or larger loop** with lower fan speeds would be ideal. Additionally, AMD has provided optional VRM cooling brackets for their motherboards, as overclocking these CPUs can generate significant heat.

## Pricing and Availability
The Threadripper 2 series offers something for every budget and use case:
- **29:20**: $650 (12 cores, 24 threads)
- **2950 X**: $900 (16 cores, 32 threads)
- **2970 WX**: $1,300 (24 cores, 48 threads)
- **2990 WX**: $1,800 (32 cores, 64 threads)
Prices for the Threadripper 2 series are competitive compared to their predecessors. For example, the **2950 X** replaces the **1950 X**, which is currently priced at around $780. Despite this, some users may feel that the premiumThreadripper 2 models (like the 2990 WX) are overpriced for their intended market segment.

## Final Thoughts and Future Plans
While AMD has done an excellent job improving the architecture and performance of Threadripper 2, there are still questions about what is under embargo and what isn't. The lack of official documentation from AMD makes it difficult to fully validate some claims.
Moving forward, we plan to conduct our own testing once we receive samples of these CPUs. Depending on availability, we hope to provide detailed benchmarks and reviews in the coming months. Stay tuned for more updates as we continue to move into our new office!
