嘿嘿！鬼佬又开始想了。。
有种天朝领先全世界的优越感，id那是不能提的，多谢喝了某老师的酒！！！！！

Meanwhile on the compute side, AMD’s new Asynchronous Compute Engines serve as the command processors for compute operations on GCN. The principal purpose of ACEs will be to accept work and to dispatch it off to the CUs for processing. As GCN is designed to concurrently work on several tasks, there can be multiple ACEs on a GPU, with the ACEs deciding on resource allocation, context switching, and task priority. AMD has not established an immediate relationship between ACEs and the number of tasks that can be worked on concurrently, so we’re not sure whether there’s a fixed 1:X relationship or whether it’s simply more efficient for the purposes of working on many tasks in parallel to have more ACEs.

One effect of having the ACEs is that GCN has a limited ability to execute tasks out of order. As we mentioned previously GCN is an in-order architecture, and the instruction stream on a wavefront cannot be reodered. However the ACEs can prioritize and reprioritize tasks, allowing tasks to be completed in a different order than they’re received. This allows GCN to free up the resources those tasks were using as early as possible rather than having the task consuming resources for an extended period of time in a nearly-finished state. This is not significantly different from how modern in-order CPUs (Atom, ARM A8, etc) handle multi-tasking.

PS4的GPU采用GCN2.0架构，1152核心，介于8770和8850之间，1152*2*800=1843200Mflops
720只有768核心，768*2*800=1.2Tflops

意思就是599打不住了？

VGleaks出新文章了：http://www.vgleaks.com/orbis-gpu-compute-queues-and-pipelines/

A lot of rumors are flooding internet about GPU enhancements in PS4. We will try to give more info about this AMD’s custom graphic card inside PS4.

As we said Liverpool GPU is derived from R10XX family from AMD (Southern Islands). Front end blocks, back end blocks, and the basics of the shader cores remain largely unchanged. But they have added some major new additions (mostly aimed at improving the capabilities and efficiences of compute workloads).

Liverpool has multiple compute rings and pipes that provides fine control over how the system resources are divided amongst all of the application’s GPU workloads. This pipelines can perform simulteneous asynchronous compute.

This diagram exposes the queues and pipelines from PS4 GPU (you can click to enlarge the image).


You can compare the PS4 GPU rings (above) with R10XX retail (below)


PS4 GPU has a total of 2 rings and 64 queues on 10 pipelines

- Graphics (GFX) ring and pipeline
Same as R10xx
Graphics and compute
For game



- High Priority Graphics (HP3D) ring and pipeline
New for Liverpool
Same as GFX pipeline except no compute capabilities
For exclusive use by VShell



- 8 Compute-only pipelines
Each pipeline has 8 queues of a total of 64
Replaces the 2 compute-only queues and pipelines on R10XX
Can be used by both game and VShell (likely assign on a pipeline basis, 1 for VShell, and 7 for game)
Queues can be allocated by game system or by middleware type
Allows rendering and compute loads to be processed in parallel
Liverpool compute-only pipelines do not have Constant Update Engines (presented in R10XX cards)

久多说的什么来着，什么东西会很贵，真的很贵来着。

那个头发的事情说了没有？

720,你已经死了！

然后骚尼说PS4卖599，然后就没有然后了:D

299挥泪甩卖，sony赢了

399,顶级PC,是不是这个道理？

这也行啊？？
NVIDIA is continuing to be a partner for physics middleware on PlayStation 4

不过有些我记得有些游戏a卡也可跑的，像无主2，一分钱授权费都不用。。

谁能简单介绍一下这个neogaf到底是个什么性质的网站？为啥软饭们喜欢当成权威？
卡马克崇拜者集中地？外来和尚好念经or美国的月亮都是圆的系列？
我以前去看过几眼，怎么感觉就是美国版tgfc？

PS：曾几何时，感觉软青跟美分是一类人，当然不是所有的人。

不是软饭当权威，是所有的饭当权威。
那是世界上最大的（主机）游戏论坛。
最强的游戏机硬件论坛是B3D。

neogaf有业内的存在， 但也有愤青的存在， 如是而已
neogaf的青战起来一样也是傻逼整堆就是了
