ISE和VIVADO哪个更快

在将i7-5775C与英特尔最近的处理器进行基准测试时，我得到了很好的结果。
它已经两代了，它没有特别高的时钟速度，它不支持很多线程。
但它有一个128MB的L4缓存，这是最新的可插拔CPU所没有的。
（嵌入式DRAM旨在加速集成显卡，但如果使用外置（PCI-e）显卡，它似乎可用作L4缓存。）
在我的基准测试中，Vivado的速度并没有随着可用内核的数量而明显改变。
ISE PAR有一个选项，允许您指定它可以使用的线程数。
我的经验是，1,2,3或4个线程之间至多有几个百分点的差异。
有时4慢于1。
请记住，您的Vivado跑步将由不同的通行证组成。
一些（例如IP集成）将大量访问磁盘。
一些（例如路由）将受CPU或内存限制。
问候，

I get good results when benchmarking an i7-5775C against more recent processors from Intel.
 
It's two generations old, it doesn't have a particularly high clock speed, it doesn't support many threads.  But it has a 128MB L4 cache that the more recent pluggable CPUs don't have.  (The embedded DRAM is meant to speed up the integrated graphics, but it seems that it's available as L4 cache if you use an external (PCI-e) graphics card.)
 
In my benchmarks, the speed of Vivado does not change appreciably with the number of cores available.
ISE PAR has an option that allows you to specify the number of threads it can use.  My experience is that there is at most a few % difference between 1, 2, 3, or 4 threads.  Sometimes 4 is slower than 1.
 
Please bear in mind that your Vivado run will be made up of different passes.  Some (e.g. IP integration) will access the disk a lot.  Some (e.g. routing) will be CPU or memory bound.
