国产内存爆发！长鑫DDR5颗粒性能实测：与海力士旗舰差距不到1%_我的网站

A |     8月25日消息，根据B站UP主芝士华莱士的最新实测，国产长鑫存储颗粒已能稳定运行在DDR5-8000频率，且在部分生产力及游戏测试中，其性能表现已与海外主流的海力士新旗舰M-die方案高度接近。    Sri Lanka on Tuesday opened its fuel import and retail sales markets for firms belonging to oil-producing countries, a measure which the government hopes may ease crippling shortages that have paralyzed most of the economic activity in the island nation.,The move will also end the duopoly of state-owned Ceylon Petroleum Corporation (CPC), controlling 80% of the fuel market, and Lanka IOC, a unit of Indian Oil Corporation.,The cabinet approved the proposal hours before a high-level delegation left for Qatar and Russia to arrange fuel for immediate needs.,Minister of Energy Kanchana Wijesekera said the firms would be able to operate without Forex requirements from the Central Bank of Sri Lanka (CBSL) and other banks.,“This exemption of Forex requirements will be permitted for the first few months of operations,” the minister said.,The cabinet has asked the CPC to provide its logistics, stocking, and distribution service to the foreign firm, suggesting that the government would privatize a debt-ridden state-run firm which controls around 80 percent of the market.,However, the refinery business will remain with the Ceylon Petroleum Corporation, which was operating with a monthly loss of approximately $90 million last year.,On Monday, the government restricted fuel sales to port, health services, and food transport until 11 July, citing the "unprecedented state of finance and foreign exchange crisis.”,“All other sectors are requested to stay at home and provide services online in this difficult time,” Bandula Gunawardena, the government spokesman, said.,Last Wednesday, Sri Lankan Prime Minister Ranil Wickremesinghe said the economy had “completely collapsed,” showing the inability to purchase fuel as shortages of essentials and electricity worsen.,The government is in talks with Qatar, Russia, and India to arrange for fuel until the forex crisis gets resolved. The island nation has also planned a credit conference with the participation of India, China, and Japan to arrange for loans for food and fuel purchases.,A negotiation with the International Monetary Fund is in progress and will likely be finalized by July.,Want to know more?

B |     两者带宽表现基本处于同一水平，海力士凭借更收紧的时序，在内存延迟方面取得领先。         在Geekbench 6测试中，长鑫8000MT/s方案获得24576分，与海力士同频率方案的24790分相比，差距仅为0.86%左右。     游戏性能上，在1080P分辨率测试中，在《彩虹六号：围攻X》中，两套8000MT/s内存的平均帧数仅相差5帧，差距不到1%。而在《刺客信条：黑旗重制版》中，两者的帧数表现基本处于同一水平线。         除此之外，在《使命召唤21》和《极限竞速：地平线5》等大作中，两套高频方案的帧数表现几乎完全一致，差距不足1FPS。
