NVIDIA下一代Pascal顯卡近日在SC15大會上有了更多資訊放出
包括相關運算設計、峰值計算能力、制程工藝等,基本與之前的傳聞特性一致,Pascal有
望在明年初上市。
雖然NVIDIA沒有公開代工Pascal晶片製造商的名字,但wccftech表示可以確認Pascal顯卡
將採用台積電的16nm FinFET工藝制程
更先進的工藝使Pascal核心擁有160-170億電晶體數量,兩倍於現在的Maxwell旗艦GM200
顯卡。
目前Pascal的旗艦GP100已經流片,有望在明年上半年發佈。
NVIDA老總黃仁勳表示Pascal進一步提高混合精度運算能力,將同時具備FP16、FP32和
FP64運算
雙精度浮點性能為4TFLOPS,單精確度可達到10TFLOPS。NVIDIA計畫在明年也會將Pascal
帶到超算領域的Telsa系列顯卡上,目前他們的競爭對手是AMD基於Hawaii核心的專業卡
提供FP32和雙精度運算。另外Pascal還帶來了NVLink和UVM技術,提供5-12倍于普通PCIe
的頻寬。
Pascal能實現4TFLOPS雙精度浮點運算能力,32GB HBM2顯存帶來的1TB/s頻寬也功不可沒
NVIDIA目前的旗艦Tesla K80加速卡配備雙GK210(Kelper架構)GPU最高也只能達到
2.91TFLOPS
單GK180的Tesla K40上雙精度也只有1.43TFLOPS。而對手AMD上最好的單晶片專業卡
FirePro S9170雙精度性能為2.62TFLOPS。
