問下 2080 可否硬解 8K 江南 style?

x264 嘅 8K 10 系顯卡唔支援硬解,被迫要用到 2679v4 或 2990WX 呢類怪物軟解,先可以保證順暢。
如果 20 系顯卡可以硬解到佢,就無謂買多核 CPU 喇

我用gtx 980  睇8k  也好清好順喎

900 系同 10 系 可以硬解嘅 8K 片(YouTube 嗰啲 VP9 webm)唔好攞嚟比
情況完全唔同

今代好似無乜提到影像方面有咩進步或提升,只有hdmi 2.0b,接4k TV睇10 bit hdr片未必有改善,加上2080得8Gb ram又唔可以行盡Madvr,2080Ti買黎睇片又好似好唔值,心大心細俾萬幾蚊出黎買卡,原來都唔夠TV內置player靚,倒不如萬幾蚊換過部QLED TV好過

    X264 既 8k 新片應該唔會再出

主流係h265

NVIDIA TURING GPU ARCHITECTURE WHITE PAPER
Page 21-22.

Enhanced Video Engine
Compared to prior generation Pascal and Volta GPU architectures, Turing supports additional video decode formats such as HEVC 4:4:4 (8/10/12 bit), and VP9 (10/12 bit) (see the Video and Display Engine section starting on page 21 for more details). The enhanced video engine in Turing is capable of decoding significantly higher number of concurrent video streams than equivalent Pascal based Tesla GPUs (see Table 2).

Turing GPUs also ship with an enhanced NVENC encoder unit that adds support for H.265 (HEVC) 8K encode at 30 fps. The new NVENC encoder provides up to 25% bitrate savings for HEVC and up to 15% bitrate savings for H.264.
Turing’s new NVDEC decoder has also been updated to support decoding of HEVC YUV444 10/12b HDR at 30 fps, H.264 8K, and VP9 10/12b HDR.

咁即係理論上得,8K 江南 style 係 30fps

下面呢篇文講舊卡第日都會得。

    NVIDIA's Turing GPUs can process 8K video in real time

NVIDIA's latest Quadro RTX GPUs with advanced ray-tracing tech cost between $2,300 and $10,000. Land said that 24fps 8K has been tested on the $6,300 P6000, but added "we are confident that the lowest-end Turing will [also] work well." Interestingly, the tech will eventually allow for 8K playback on current-generation cards like the NVIDIA GeForce GTX 1080 Ti. "This is more a code thing than a hardware thing," said Land.

RED also strongly hinted that the new tech will work on NVIDIA's incoming consumer GPUs, too. "The release of this is tied to the new hardware but everyone on NVIDIA will eventually win," said Land. "The story is only half complete ... there are a slew of new 'consumer' NVIDIA cards coming."

師兄既意見係話呢代卡對影像方面會靚過上代?
