NVIDIA的Pascal架构显卡已经发了两个核心了,首发的是GP100大核心,接着是现在GTX
1080/1070显卡用的GP104核心,不过前一个核心主要面向HPC市场,不会出现桌面版,GP104核心性能很强大,但还不能委以超旗舰重任。此前传闻NVIDIA的游戏用大核心还有个GP102,现在已经被AIDA64软件证实,而中低端市场还会有GP106、GP107及GP108核心,现在Pascal家族一家人已经整整齐齐团聚了。
GXT 1080显卡之后,NVIDIA还会有一大波Pascal核心显卡待发
AIDA64前身是Everest,是著名的系统硬件识别、测试软件,日前他们在FB上公布了Pascal家族显卡的全部PCI设备ID(Device
ID),而且会有A、B两种版本,其中后缀为B的核心有可能是改进版。
我们按照不同核心来排列下:
GP100核心

GP102核心
1B00 Graphics Device (#GP102-A)1B01 Graphics Device (GP102-A)1B30 Graphics Device (GP102GL-A)1B38 Graphics Device (GP102GL-A)1B3E Graphics Device (GP102GL-A)

GP104核心
1B80 GeForce GTX 1080 (GP104-A)1B81 Graphics Device (GP104-A)1B82 Graphics Device (GP104-A)1B83 Graphics Device (GP104-A)1BB0 Graphics Device (GP104GL-A)1BB1 Graphics Device (GP104GL-A)1BB4 Graphics Device (GP104GL-A)

GP106核心
1C00 Graphics Device (GP106-A)1C01 Graphics Device (GP106-A)1C02 Graphics Device (GP106-A)1C03 Graphics Device (GP106-A)1C30 Graphics Device (GP106GL-A)
1C41 Graphics Device (GP106-B)1C42 Graphics Device (GP106-B)1C43 Graphics Device (GP106-B)1C70 Graphics Device (GP106GL-B)
GP107核心
1C80 Graphics Device (GP107-A)1C81 Graphics Device (GP107-A)1C82 Graphics Device (GP107-A)1CA7 Graphics Device (GP107GL-A)1CA8 Graphics Device (GP107GL-A)1CAA Graphics Device (GP107GL-A)
1CC2 Graphics Device (GP107-B)
GP108核心
1D01 Graphics Device (GP108-A)
这样一来,NVIDIA规划的Pascal家族显卡就会有GP100、GP102、GP104、GP106、GP107及GP108至少6个核心,数字编号越高,显卡定位越低,其中GP100不会出现在消费级市场,GP102才是GeForce显卡未来的新旗舰,有可能用在GTX
1080 Ti或者GTX Titan X二代显卡上。
此前也有消息曝光了GP102核心的规格,核心面积从GP104的318mm2提升到478mm2,但低于GP100的610mm2,CUDA核心数为3840个,96组ROP单元,基础频率1507MHz,加速频率1621MHz,显存位宽384bit,显存频率12GHz,用的也是GDDR5X而非HBM
2,带宽576GB/s,TDP为250W,售价为1399美元。
GP104核心已经见过了,GTX 1080及尚未解禁的GTX 1070显卡用的都是这个核心,未来的GTX
1060显卡传闻也是GP104核心阉割而来,不过现在来看已经不确定了,GTX 1060也有可能是用GP106核心,192bit位宽,6GB显存。
再往下还有GP107和GP108两个核心,前者可能用于GTX 1050显卡,后者定位就更低了,不知道NVIDIA是不是还打算把目前的GT
940显卡也升级到GTX 1040?
