Let's dive into the details.

Early Shipments and Reference Boards

Despite rumors suggesting otherwise, AMD has quietly begun shipping early reference boards and GPU samples to its engineering labs. The evidence comes from the latest shipping log at, where several new PCBs have been spotted alongside the elusive GPU.

The Navi 48 XTX GPU

The star of the show is the AMD Radeon RX 8000 desktop graphics card featuring the Navi 48 XTX GPU. This high-end SKU utilizes the flagship RDNA 4 graphics die. But what exactly is the Navi 48 XTX?

  • Navi 48 XTX: The top-tier RDNA 4 GPU die, outperforming its sibling, the Navi 44.
  • GFX1201 Family: The Navi 48 GPUs fall under this family, while the Navi 44 GPUs belong to the "GFX1200" family.

PCB Details

The shipping manifest reveals four PCBs associated with the upcoming AMD RDNA 4 GPU family:

  1. 102-G28211
  2. 102-G28501
  3. 102-G28201
  4. 102-C48701

Specifically, the AMD Navi 48 XTX "Navi 48" GPU employs the 102-G28201 PCB.

New Architecture and Ray Tracing

What can we expect from the Navi 48 XTX? Here's the scoop:

  • New Architecture: The Navi 48 GPU introduces a brand-new architecture, distinct from RDNA 3. Notably, it features an entirely revamped ray-tracing engine.
  • RT Performance Boost: This enhanced ray-tracing engine is crucial for AMD, as it will power next-gen consoles from Sony and Microsoft. Expect a significant boost in ray-tracing performance compared to existing RDNA cards, even rivaling NVIDIA's offerings.

Performance and Pricing

  • Performance: The AMD Navi 48 XTX "RDNA 4" GPUs are projected to perform similarly to the existing Navi 31 SKUs (XL/XT). However, they'll offer better power efficiency.
  • Pricing: Good news for gamers-the Navi 48 GPUs are expected to be priced much lower than the top RDNA 3 GPUs. Look forward to "Radeon RX 7900" series performance at around $500 US or less.

Next-Gen Memory Standard

While AMD hasn't spilled all the beans, a recent Micron press release hints at GDDR7 as the next-generation memory standard for the RDNA 4 GPU family. Reports also suggest 18 Gbps GDDR7 memory across all RX 8000 models.

Stay tuned for more updates as we approach the official launch. AMD's Computex keynote may reveal additional details about the Radeon RX "Gaming" lineup. Exciting times ahead for PC enthusiasts!
