北极星怎么了？GTX1080《奇点灰烬》性能部分披露
本帖最后由 飞翔的企鹅 于 2016-5-10 10:22 编辑目前外媒又曝光了一组AMD和Nvidia下一代显卡的跑分图，结果显示AMD这一次悲剧了，北极星10和11在《奇点灰烬》的测试中远落后于Pascal显卡。
由于AMD的测试驱动还处于Beta状态，因此部分测试并没有相应的分数
因图比较多，我选取了部分帕斯卡和北极星有关系的成绩
4K发狂画质
2K发狂画质
1080发狂画质
1080极限画质
1080高画质
1080中画质
1080低画质
结论，AMD的BETA驱动明显存在问题，此成绩不代表北极星的正常水平。GTX1080在DX12下的性能确实强过上代核心，至少这个老黄没骗人。

。。。别的地方都是说4K极限，上一代A卡旗舰吊打N卡旗舰
你呢。。拜托。。本代N卡旗舰吊打本代A卡中端。。。。 1.AMD的Beta驱动问题是有的也和P10定位有关
P10 价格定位个人认为是冲着X1060去的（否则大家生意以后都没法做了）
P10 最高的480X（暂且他不改名字）理论成绩也只是能勉强追平980TI. （大伙都知道实际游戏和理论成绩总是有差别）
2.X1080和FuryX的对比还是说明了很大问题
首先X1080和980，980Ti相比DX12成绩提升很大，但是比FuryX的优势还是不明显
如果帕斯卡彻底解决了ACE的问题再加上高主频原则上应该比FuryX搞得更多事实上却没有
但是这个测试的疑点在于以下两点：
1.北极星P10 Crazy 4K 的成绩是有的， Crazy其他分辨率下成绩没有
2.北极星只显示了设备编号，而没有具体型号。到底谁拿去做测试了
3.那个未命名的NV显卡是否是X1070? SCE-PhyreEngine 发表于 2016-5-10 12:34

说的优势不明显是指在Crazy 设定下。这个设定下对于显卡压力很大

Compute PreemptionThe new Pascal GP100 Compute Preemption feature allows compute tasks running on the GPU to be
interrupted at instruction-level granularity, and their context swapped to GPU DRAM. This permits other
applications to be swapped in and run, followed by the original task’s context being swapped back in to
continue execution where it left off.
Compute Preemption solves the important problem of long-running or ill-behaved applications that can
monopolize a system, causing the system to become unresponsive while it waits for the task to complete,
possibly resulting in the task timing out and/or being killed by the OS or CUDA driver. Before Pascal, on
systems where compute and display tasks were run on the same GPU, long-running compute kernels
could cause the OS and other visual applications to become unresponsive and non-interactive until the
kernel timed out. Because of this, programmers had to either install a dedicated compute-only GPU or
carefully code their applications around the limitations of prior GPUs, breaking up their workloads into
smaller execution timeslices so they would not time out or be killed by the OS.
Indeed, many applications do require long-running processes, and with Compute Preemption in GP100,
those applications can now run as long as they need when processing large datasets or waiting for
specific conditions to occur, while visual applications remain smooth and interactive—but not at the
expense of the programmer struggling to get code to run in small timeslices.
Compute Preemption also permits interactive debugging of compute kernels on single-GPU systems. This
is an important capability for developer productivity. In contrast, the Kepler GPU architecture only
provided coarser-grained preemption at the level of a block of threads in a compute kernel. This blocklevel preemption required that all threads of a thread block complete before the hardware can context
switch to a different context. However when using a debugger and a GPU breakpoint was hit on an
instruction within the thread block, the thread block was not complete, preventing block-level
preemption. While Kepler and Maxwell were still able to provide the core functionality of a debugger by
adding instrumentation during the compilation process, GP100 is able to support a more robust and
lightweight debugger implementation.
GP100白皮书提到支持“抢占式”任务计算，这对异步计算有帮助么

说明上看个人认为有一定帮助，但是提升程度未知。。

第四个疑点就是出了Crazy设定的对比结果比较全之外，其他设定成绩不全。
至于FuryX为什么画质设定越高越强悍，我之前的帖子有说明，DX12下复杂的负载任务越高，ACE的拆分成并行处理的特点就越能体现 大家还是稍安勿燥，X1080有得卖的时候，我会入手一个（A,N 两家旗舰次旗舰每一代我都会买），然后和Fury（FuryX懒的挪地方）暂时做个对比，DX11游戏我手头上有孤岛惊魂原始杀戮，全境封锁，正当防卫，星战前线。DX12游戏有奇点灰烬，杀手6（古墓丽影崛起只能算DX11游戏，量子破碎下载老出事）到时候测试下。 SCE-PhyreEngine 发表于 2016-5-10 12:57

相比Hawaii 8ACE，斐济前端改成4个ACE+2个Hardware Scheduler有什么目的？
也不排除4k极限测试下1070/ 1080受制于显存带宽性能上不去，毕竟TITAN X跟FURY性能差距也没有明显拉大 表示在用7770，显卡性能严重过剩
1440P下好像1080并不比980ti快多少 不显示名称的N卡如果是1070为何有两种成绩，估计不是一款 泰坦X也有很多成绩不完整，也是驱动问题？ SCE-PhyreEngine 发表于 2016-5-10 12:34

P10出了以后AMD高端还是用fury顶1080？

斐济一直是8ACE，Hardware Scheduler是硬件着色调度器。。你想成一个辅助单元就理解了

7770再过剩你只能用APU核显了
