Quadro P400 - Linux

    Meu computador de live/gravação era baseado em um Ryzen 3 PRO 3200G, a Vega 8 é uma ótima alternativa de baixo custo para Encode, tem suporte a h264 e HEVC, transmito para o YouTube a 1080p 60FPS com bitrate VBR de 15M a 20M. A Vega 8 consegue manter esta configuração com folga, o encode dela fica em torno dos 75%. Porem estava querendo fazer multi-stream e apenas a Vega 8 não daria conta, então recentemente adquiri uma Nvidia Quadro P400 2GB.

     Esta Quadro P400, é da geração pascal e usa o drver 580 no linux, tem suporte a h264 e suporte parcial a HEVC, caso queira saber das demais especificações pode consultar no techpowerup, mas no momento o mais importante seria sua capacidade de Encode, então vamos para os detalhes.

Esta é a live de teste que fiz:

YouTube  no youtube esta usando a Vega , como tinha comentado, nas outras duas plataformas foi usando a P400

Twitch 

Kick  

                                                            Live teste da P400

Esse print foi tirado de um trecho da live, como podem ver a Vega 8 esta a 75% de uso enquanto a P400 esta a 52%, ficou nesta media a live toda, podem conferir pelos links acima.

A P400 esta com uma boa folga, a três lives poderiam ser feitas por ela tranquilamente!

 Tem um canal chamado  DarkenedCyrus, que em 2022 fiz um comparativo desta Quadro P400 com uma RTX 3080TI, neste cenário que estamos discutindo, transmissão ao vivo, vale a pena dar uma olhada, você vai ser surpreender.

 

Basicamente é isso, valeu, flw!
