Core Viewpoint - Nvidia's latest generation of graphics cards, particularly the RTX 5060, is underwhelming in performance and specifications, resembling older models like the RTX 5050 rather than meeting the expectations for a 60 series product [1][3][5]. Group 1: Product Specifications - The RTX 5060 has a core configuration and memory bandwidth that aligns more closely with the RTX 5050, indicating a significant downgrade in expected performance for a 60 series card [5][10]. - Historical data shows that the core count for the RTX 5060 is only 18% of the flagship model, which is significantly lower than the average for 60 series GPUs, which typically range around 36% [10][12]. - The RTX 5060's specifications are comparable to older models like the GTX 750 and GTX 1050, suggesting a regression in performance standards for the 50 series [10][12]. Group 2: Pricing and Value - The pricing strategy for the RTX 5060 reflects a trend where Nvidia is charging higher prices for lower-performing products, with the RTX 5060 priced at 15% of the flagship GPU, which is a deviation from historical pricing norms [18][21]. - The RTX 5060 is positioned as the second cheapest 60 series model in seven generations, yet it offers performance that is more akin to a 50 series card, leading to perceptions of value erosion among consumers [21][35]. - The increase in production costs has not been matched by corresponding improvements in GPU specifications, leading to higher prices for lower performance [52][57]. Group 3: VRAM and Memory Bandwidth - The RTX 5060 features only 8GB of VRAM, which is 25% of the flagship model's capacity, falling short of historical averages where 60 series GPUs typically offered around 41% of the flagship's VRAM [32][31]. - The memory bandwidth for the RTX 5060 is significantly lower than that of previous generations, indicating a trend of reduced performance capabilities in newer models [23][27]. - The overall trend shows that Nvidia's GPUs are not keeping pace with the memory requirements of modern gaming, particularly when compared to the specifications of contemporary gaming consoles [48][40]. Group 4: Market Dynamics and Competition - Nvidia's strategy appears to be driven by a desire to maximize profits from AI GPU sales, leading to a compromise in the quality and performance of gaming GPUs [51][57]. - The lack of meaningful competition in the GPU market has allowed Nvidia to maintain high profit margins while passing increased production costs onto consumers [57][58]. - The introduction of AMD's Radeon RX 9000 series may begin to exert pricing pressure on Nvidia, potentially benefiting consumers in the gaming GPU market [58].

2025年6月3日，世界半导体贸易统计组织（WSTS）发布了2025年和2026年半导体市场预测。此 前，在2024年11月发布的预测中，WSTS预测2025年的市场增长率将比上一年高出11.2%。此次发布 的预测保持不变。从截至2025年4月的半导体市场情况来看，迄今为止的出货量同比增长了19.3%， 因此维持预测不变可以说是比较保守的看法。对于接下来的2026年，预测同比增长8.5%，但笔者认 为也有可能出现负增长。结合目前的情况，我想展望一下未来。 分立器件受电动汽车放缓冲击，能否复苏？ 预计2025年分立器件市场将同比下降2.6%。此前的预测是增长5.8%，但已向下修正。从2025年1月 至4月的实际结果来看，分立器件市场同比下降6.9%，预计此后将有所回升。虽然与去年同期相比的 负增长持续到了4月，但负增长率呈下降趋势，因此这一预测并非不合理。最大的担忧在于，占据该 领域绝大部分的功率晶体管市场的低迷持续时间比预期更长。尤其是电动汽车（EV）需求的低迷对 其造成了沉重打击。不过，笔者认为，从中长期来看，汽车电动化将继续推进，而作为电动化关键器 件的功率晶体管的需求也将稳步增长。2026年的预测是同比 ...
