一 |     (ECNS) -- Chinese scientists have identified a flowering plant species on the Qinghai-Xizang Plateau as a new lineage of carnivorous plants, providing evidence for Charles Darwin’s prediction more than 150 years ago.         A study published on Tuesday found that Saxifraga candelabrum, a flowering plant, can attract, capture and digest insects, while absorbing nitrogen from their bodies.    Researchers observed sticky glandular hairs trapping prey, detected digestive enzyme activity, and confirmed nutrient absorption using isotope-labeled fruit flies.    Led by Sun Hang’s team at the CAS Kunming Institute of Botany, with collaborators from Wuhan Botanical Garden, Jishou University and the University of Florida, the findings resolve a long-standing question over whether certain Saxifraga species possess true carnivorous traits.    In 1875, Darwin proposed that some species of Saxifraga might be carnivorous because they possess sticky glandular hairs capable of trapping insects. However, evidence supporting the hypothesis had remained unavailable until now.    (By Helen Mo, intern Liu Shuangjing)                    。    8月25日消息，硬件改造团队Paulo Gomes近日将一张影驰RTX 2080 Super名人堂的显存从8GB翻倍至16GB，此前还尚未有过同类改造案例。     改造过程中团队将原装8颗三星1GB GDDR6显存芯片，全部更换为2GB颗粒，再调整显卡的显存配置电阻，以此让GPU识别更高密度的显存模块。         调试期间在低频下还出现了显示异常，团队修改了NVIDIA驱动配置，让显卡保持在高性能状态才解决。改造版还加装了一个物理开关，可以在8GB和16GB两种模式之间切换，方便同一张卡上对比测试。          测试选了《生化危机：安魂曲》，画面选项全部拉满，关闭超分辨率和帧生成，刻意让显存占用超过8GB原始容量。         8GB模式下帧率在24到26帧之间徘徊，显存占用已经见顶，切换到16GB模式后，显存占用升至约11GB，帧率提升到32到34帧，增幅约28%，对系统内存的依赖也明显降低。         不过需要明确一点，这项改造并没有让RTX 2080 Super整体变快，TU104核心规格不变，显存带宽也没有提升。

二 | 28%的帧率提升仅在显存容量成为瓶颈时才会出现，如果游戏本身在8GB内就能跑完，不会有任何收益。          团队表示后续可能在更多游戏和AI负载中测试这张改造卡，看看大显存在哪些场景下能带来可量化的收益。
