AMD has officially unveiled the RX Vega 64, positioning it as a direct competitor to NVIDIA's GTX 1080. This new graphics card is expected to shake up the high-end GPU market with its advanced architecture and performance capabilities. The RX Vega series marks the first consumer-grade graphics cards to use HBM2 (High Bandwidth Memory 2) technology. The memory chips are sourced from Samsung, and the Vega 64 model features two stacks of HBM2, totaling 8GB of high-speed memory. This represents a significant step forward in terms of bandwidth and efficiency compared to traditional GDDR5 memory. Unlike GDDR5, which is typically mounted separately on the PCB, HBM2 is stacked directly on top of the GPU using a silicon interposer. This integration allows for much higher data transfer rates and reduced latency, but it also introduces unique design challenges during manufacturing. Interestingly, Dutch tech site Hardware.Info discovered an unusual feature on the RX Vega 64: the GPU core is noticeably taller than the HBM2 memory chips. This means that the components are not at the same physical level, which is quite different from typical designs where everything is more evenly aligned. However, this discrepancy is reportedly addressed through a padding design, which helps to level out the height difference between the GPU and the memory chips. While this might seem like a minor detail, it could have implications for thermal performance and cooling solutions. According to Hardware.Info’s analysis, the height difference may impact heat dissipation, as uneven surfaces can affect airflow and thermal conductivity. This could mean that the cooling system needs to be more carefully optimized to ensure stable performance under load. When asked about the issue, AMD did not directly respond. Instead, the company referred questions to its channel partners. These partners explained that the HBM2 memory and GPU were packaged by different companies, which might have contributed to the height difference. They also noted that such variations are common in the industry and do not necessarily indicate a flaw in the design. Overall, while the RX Vega 64 is a powerful and innovative product, the slight height difference between the GPU and HBM2 memory highlights the complexities involved in integrating next-generation technologies. As the market continues to evolve, we can expect more insights into how these design choices impact real-world performance and user experience. 35 Kv Transformer,Low Noise 35 Kvoil-Immersed Transformer,Oil Immersed Transformers With High Load Capacity,High Voltage Insulated Oil-Immersed Transformer Tianhong Electric Power Technology Co., Ltd , https://www.tianhongtransformer.com
