PCI-SIG today announced that PCI Express (PCIe ) 6.0 technology will double the data rate to 64 GT/s while maintaining backwards compatibility with previous generations and delivering power efficiency and cost-effective performance. The PCIe 6.0 specification is actively targeted for release in 2021.
PCIe 6.0 Specification Features Delivers 64 GT/s raw bit rate and up to 256 GB/s via x16 configuration Utilizes PAM-4 (Pulse Amplitude Modulation with 4 levels) encoding and leverages existing 56G PAM-4 in the industry Includes low-latency Forward Error Correction (FEC) with additional mechanisms to improve bandwidth efficiency Maintains backwards compatibility with all previous generations of PCIe technology "PCI Express technology has established itself as a pervasive I/O technology by sustaining bandwidth improvements for five generations over two decades," Dennis Martin, an analyst at Principled Technologies, said. "With the PCIe 6.0 specification, PCI-SIG aims to answer the demands of such hot markets as Artificial Intelligence, Machine Learning, networking, communication systems, storage, High-Performance Computing, and more." "Continuing the trend we set with the PCIe 5.0 specification, the PCIe 6.0 specification is on a fast timeline," Al Yanes, PCI-SIG Chairman and President, said. "Due to the continued commitment of our member companies, we are on pace to double the bandwidth yet again in a time frame that will meet industry demand for throughput."

最近剛好也遇到HDMI頻寬的問題
看了前面的分析想請教一下 若TV只能支援到2.0B的情形下 用電腦輸出到電試看一般4k.1080p影片(非HDR) 是要選8bit RGB 還是10bit YUV422? |
只要你接的訊號來源是PC的話
基本上都應該要選RGB... |
非HDR建議RGB 4:4:4就好.
24/30/60FPS有要求嗎? |

借串問一下
早上到小黃屋訂了一台32" 1440P 144Hz的曲面電腦螢幕 可是搞不清楚1440P 144Hz需要的hdmi或dp的版本要求 手邊有兩張老顯卡(hd5850跟hd7850),原本查5850能支援1440p解析度,但hdmi應該只有1.1版,似乎沒辦法上到144Hz 7850的hdmi/dp版本似乎是1.4a跟1.2版 可是還是不清楚這是否能上到 144Hz 還是說其實找個主動式轉接頭就能簡單搞定這一切? :jolin: 遊戲部分沒啥在玩,主要是希望一般應用之類得可以正常使用144Hz更新率就好,等年底才考慮換新顯卡 |

使用既有線材規格 USB3.2 2x2 (雙向20G) 單向40G TB3/USB4 (雙向40G) 單向80G 40G大概可以有5米長 80G...市售TB3有認證的多長? 以及FCE糾錯 其實DP1.4/HDMI2.1也支援的 在啟用DSC時 DP2.0打算要擴大應用 再看看吧... 其實40G不太需要的 糾錯也不是沒代價 |

囈.......FEC |

擴大應用就是4K、8K |
一年多前在淘寶找了很久有通過雙向40Gbps的TB3綫材.
基本上只有看到三種長度規格:0.5m / 1m / 2m. 看到最便宜的2m綫要400人民幣. |
