The AMD RX Vega 64 graphics card has officially made its debut, positioning itself as the top competitor to the NVIDIA GTX 1080. This new release marks a significant step forward in high-end GPU technology, especially with its advanced memory system and performance capabilities. Vega 64 is the first consumer-grade graphics card to feature HBM2 (High Bandwidth Memory 2) from Samsung. It uses two stacks of HBM2 chips, totaling 8GB of memory. This type of memory is designed to be stacked directly on top of the GPU, offering much higher bandwidth compared to traditional GDDR5 memory. Unlike GDDR5, which is typically mounted separately on the PCB, HBM2 is integrated using a silicon interposer that connects the GPU and memory physically. This design allows for a more compact and efficient layout, but it also presents unique challenges in terms of thermal management and manufacturing precision. Interestingly, Dutch tech site Hardware.Info recently noticed an unusual detail on the Vega 64: the GPU core is significantly taller than the HBM2 memory chips, meaning they are not aligned at the same level. This was a surprising observation and sparked some curiosity among hardware enthusiasts. However, further analysis revealed that this height difference is actually balanced out by the use of padding or spacers around the HBM2 modules. This helps ensure proper contact and stability between the GPU and the memory stack. According to HW, this padding could have an impact on heat dissipation, as the uneven surface might affect airflow and cooling efficiency. Despite this, the design is considered standard in the industry, and there's no indication that it compromises performance or reliability. When asked about the discrepancy, AMD did not provide a direct response. Instead, the company referred the question to its channel partners. They explained that the HBM2 memory and GPU were packaged by different manufacturers, which could lead to such variations. They also noted that slight differences in height are common in the packaging process and do not indicate any quality issues. Overall, the RX Vega 64 represents a bold move by AMD in the high-performance GPU market, pushing the boundaries of what’s possible with HBM2 technology and setting the stage for future innovations in graphics architecture.
