用ultra 200内置显卡解码，能通过nvidia显卡输出么？

不习惯没超线程的英特尔

编解码不支持H266/VVC么？

我之前发过一个帖子

decode only 是什么意思？只能解码不能播放？

大概率是渲染带宽不够

从7代U开始就发现，单通道根本没法解4k60，双通道2400有时候还会缺帧，到2666才基本能稳定
h155的本子，8k60的av1也是缺帧很多，差不多就对上这个8k30了

战地是公认的线程优化垃圾，有啥看的意义

战地用的线程比较多。

小核IPC提升32%？那特么都不叫小核了吧。和12代大核CPU-Z跑分基本没差了

算力有了，IO还是残废。等把缓存加大IO加强面积又压不下去了

你可以试试战地。

16.67 GHz？

应该是16.67hz，

16.67 GHz？

”系统功耗降了188W“，这个到底是怎么测出来的？同帧数下？
同显卡占用率CPU功耗能低这么多？这提升不是起飞了

个人以为，分布式P核 E核布局，有效降低积热，也是不错的创新

就看实测效果如何了

这段话出处是wccfetch不是牙膏ppt。

PPT（牙膏最终发布的ppt里没有这图）里的图片看着挺像，但Pcore1更密集，无法确认为具体是不是任务启动首先运行到Ecore。
图二里P core工作更密集，而E core就不干活了。



牙膏官网的回复更是白开水：

Yeah it's still the same scheduling behavior but intense workloads communicates hint to the CPU to shift the workload over to the P core. We fully expect that the vast majority of hours that the person hours, the man hours, of all the collective  CPUs that will be sold, most of those would probably be in a desktop case. The gamers game a few hours a day so we have to think about the total power consumption footprint of the product over its life cycle.

Starting with E-cores first is the way to go for power because people aren't playing game all the time. When they do, the game will immediately snap to P cores like they do on Lunar because that's what the games tell the Thread Director to do.

个人PC一般而言响应型请求 >> 吞吐型请求，降优先级的调度好过升优先级的调度，如果是升优先级我不看好牙膏的改良调度器。

反正性能没提升，最大创新不是去掉超线程？

Arrow Lake also features an updated Thread Director. For the P-Cores, the new telemetry structure has been designed so that threads can be directed accurately and according to the workload, and for the E-Cores, the new HW-based prediction model can be leveraged for better classification to see if the workload can be accommodated on just the E-Cores or needs to be moved to the P-cores for higher performance. Lastly, the prediction model has been improved to offer more informed & controlled scheduling across the cores.

结合这段，基本可以确认是E核优先
