2027 年先行推出部分 RDNA 5 产品，代号为“AT2”，具体型号尚未确定。AMD 和 NVIDIA 的其他所有产品都要等到 2028 年。同样，英伟达此前规划的 RTX 50 SUPER 系列显卡也因 DRAM 供应紧张而陷入不确定。有观点认为 SUPER 版本已被完全取消，也有观点认为它将作为 RTX 60 问世前的过渡方案。","market":"sh","thumbnail":null,"type":0,"news_type":0,"thumbnails":[],"rights":null,"property":[],"language":"zh","translate_title":"","themeId":null,"theme_name":"","theme_type":"","isJumpTheme":false,"source_url":"https://tech.ifeng.com/c/8wUEH7vGfms","is_publish_highlight":false,"source_rank":0,"column":"","sentiment":"0","news_top_title":null,"news_tag":"productRelease","news_rank":0,"length":0,"strategy_id":0,"source":"fenghuang_stock","symbols":["LU1935042488.USD","LU0738911758.USD","LU0949170772.SGD","LU1144417596.USD","LU0323239441.USD","LU1244550221.USD","LU0251132253.USD","AMDY","LU2265009873.SGD","BK4533","LU0511384066.AUD","IE00BDRTCR15.USD","LU1852331112.SGD","LU0289739343.SGD","LU0965509010.AUD","LU1935043452.HKD","LU2279689827.SGD","SGXZ80539844.SGD","LU1914381329.SGD","LU2322448791.USD","LU2473716301.USD","BK4573","LU2023250330.USD","LU2361045086.USD","NVDB","IE000YTNTUN2.SGD","LU0081259029.USD","LU0061474960.USD","LU2125909916.SGD","BK4551","LU0276348264.USD","LU0788109477.HKD","LU1974910355.USD","SOXQ","LU1880398471.USD","LU1069344957.HKD","NVDQ","LU2047632596.USD","LU2125154778.USD","NULC","IE0009G5SDU7.USD","LU0265550359.USD","LU0128525929.USD","LU2249611893.SGD","IE00BQXX3D17.EUR","LU0069063385.USD","ESUM","BK4543","LU0823434740.USD","IE00B3S45H60.SGD","LU2125909593.SGD","IE00BFSS7M15.SGD","IE00BMPRXN33.USD","LU1551013342.USD","LU2250418816.HKD","IE00BZ199S13.USD","LU0154236417.USD","LU1674673428.USD","2NVD.UK","LU0792757196.USD","LU2294711713.HKD","SNPE","IE00BJJMRY28.SGD","SMHX","LU2077746001.SGD","LU2089284900.SGD","LU1202635105.USD","LU0726765562.USD","LU1989772840.SGD","LU0417517546.SGD","LU2168564149.EUR","LU0157215616.USD","LU0234570918.USD","IE00BMPRXR70.SGD","LU2092627202.USD","LU1951200564.SGD","LU1992135472.HKD","LU2462591277.SGD","USD","LU1066051225.USD","BK4587","SHOC","LU0079474960.USD","LU1633808545.USD","LU2286300806.USD","SPTE","LU2506951792.HKD","LU0345768740.USD","LU0823434583.USD","LU0210536198.USD","SG9999015978.USD","FTEC","LU0289961442.SGD","LU0390134368.USD","ARTY","LU0266013472.USD","LU1035775433.USD","SMH","LU2089985449.USD","LU0957808578.USD","LU0316494557.USD","LU2420271590.USD","JGRO","LU2458330169.SGD","NVDO","LU0868494708.USD","LU0395794307.EUR","LU0203201768.USD","LU2213496289.HKD","LU0106261372.USD","SG9999000418.SGD","IE00B775H168.HKD","IE0034235295.USD","LU1861220033.SGD","HK0000304797.USD","SG9999014559.SGD","BK4512","IE00BJTD4N35.SGD","LU1064131342.USD","LU2462157665.USD","SG9999014914.USD","LU1861127337.USD","IE0009356076.USD","LU2322448957.HKD","LU2271345857.HKD","LU2148611432.USD","LU2394011477.USD","VT","LU0353189680.USD","LU0187121727.USD","AMDG","LU0158827948.USD","LU1267930573.SGD","IE00BJTD4V19.USD","LU2756315318.SGD","SG9999004303.SGD","LU1861558580.USD","LU0011850046.USD","IE00BHPRN162.USD","IE00BFSS8Q28.SGD","LU2417539215.USD","IE00BZ1G4Q59.USD","LU1732800096.USD","LU1645745479.HKD","SOXX","HK0000304805.HKD","LU2462591350.SGD","LU0354030438.USD","LU1232071149.USD","LU2999663052.SGD","LU1880398554.USD","LU0472753341.HKD","IE00BDCRKT87.USD","LU1935042991.SGD","LU0061474705.USD","LU2430703251.USD","NVDS.UK","LU0109391861.USD","LU2065171402.SGD","IE00B19Z8W00.USD","BK4614","LU1435385759.SGD","IE0004445015.USD","SNVD.UK","LU1674673691.USD","IE000W1ABFV2.USD","IXN","LU2023251221.USD","BK4554","LU2750360997.AUD","BK4548","NVII","LU2637965513.SGD","LU1571399168.USD","LU1119994496.HKD","LU0557290698.USD","LU1720051108.HKD","LU2860962120.EUR","NVD2.UK","LU0642271901.SGD","LU0820561909.HKD","LU1951198990.SGD","SG9999018865.SGD","LU0689472784.USD","FAI","LU0979878070.USD","SG9999014906.USD","LU0868494617.USD","SG9999018857.SGD","IE0034235303.USD","LU0174119429.USD","LU0056508442.USD","LU2272731865.HKD","LU1242518857.USD","LU1803068979.SGD","LU2242649171.HKD","LU0175139822.USD","LU0342679015.USD","LU0323591593.USD","LU1084165304.USD","LU2106854487.HKD","AMYY","LU1629891620.HKD","NVDS","IE00BJJMRX11.SGD","LU1670756490.USD","NVIW.SI","LU0476273544.USD","LU1280957306.USD","LU0345769128.USD","IE00BQXX3F31.USD","LU2191332357.HKD","LU2242650005.HKD","BK4592","BK4612","NVDU","LU0210528500.USD","LU2211815571.USD","PSI","LU2357305700.SGD","09788","SGXZ99366536.SGD","AMUU","LU0957791311.USD","LU1267930813.SGD","LU1839511570.USD","LU2100268510.USD","LU0795875086.SGD","LU2087621335.USD","LU2954938101.SGD","LU2471134523.USD","LEGR","AIFD","IE000Q6AESB8.SGD","IE00BN29S564.USD","LU0265550946.USD","LU0553294199.USD","LU1868837300.USD","LU0170899867.USD","SOXY","LU0256863811.USD","LU2098885051.SGD","SGXZ23171101.USD","LU1923622614.USD","AIS","GAMR","LU2237957902.USD","NVDG","LU0348723411.USD","SG9999015952.SGD","SG9999002232.USD","LU2237438978.USD","IE00BK4W5L77.USD","LU0267386448.USD","FTXL","LU1861559042.SGD","LU1699723380.USD","LU0006306889.USD","SG9999015341.SGD","FDTX","LU2272731600.USD","LU2108987350.USD","TYLG","LU2237443549.SGD","LU2054465674.USD","LU2491050154.USD","LU0708994859.HKD","LU0289960550.SGD","LU0683600562.USD","DAMD","LU2357125470.USD","L
