According to our reliable sources, Zen represents a major step forward. This uArch will be a lot better than Excavator, and will be on a par with – or very near to – Intel Haswell uArch.

【根据我们的非可靠来源的消息 - Zen的性能实现了一次飞跃。Zen架构比Excavator挖掘机好了太多,同频性能相当,或者说非常接近于Intel Haswell架构。】

FP32光线追踪

 




We have some screenshots about particular AIDA64 benchmarks (v5.70). The sample tested is an 8 cores Summit Ridge CPU (Myrtle Reference Board), and it runs at 3,0 GHz.

 【我们拿到了AIDA64部分测试的截图。测试的工程样品是8核Summit Ridge,频率3.0Ghz。】

 

However, thanks to these benchmark, we can say that Zen seems to be very good. The DDR4 bandwitdh is almost on pair with the bandwidth of the i7-6700K, while the score about CPU Hash benchmark is three times better than the score of the i7-5820K. Good, but not fantastic, the FP32 Ray Trace score.The sample used is the A0 revision (So, take these results with a grain of salt. Next revision will improve the results). The CPU runs at 3,0 GHz. The Turbo Boost feature is still disabled. The Hash score is very high thanks to the SHA hardware acceleration, but ... why is the FP32 Ray Trace score so low? It seems that Zen will have a weak FMA implementation, but the pure Floating Point Unit will be able to match up with the best Intel FPUs. Infact, our source claims that the 8 cores Summit Ridge CPU will be able to perform like the 8 cores Broadwell-E CPUs. Because of that, Intel will commercialize a 10 cores Broadwell-E CPU, and because of that Intel has backtracked: next Broadwell-EX/EP server CPUs are still here.

【这些测试中可以看出,Zen的性能非常棒。DDR4内存带宽相当于6700K,CPU Hash测试分数为5820K的三倍。FP32光线追踪的分数很好,但并不拔尖。这块ES还是A0步进(所以这些结果还是很保守的,后续步进性能会提升)。这块CPU跑在3Ghz,Boost功能关闭。因为有了SHA硬件加速,Hash分数非常高,但为什么...FP32分数这么低?看起来Zen的FMA性能会比较弱,但浮点单元的性能将会与Intel最好的FPU相当。实际上,我们的消息来源声称,8核Summit Ridge的性能相当于8核Broadwell-E(6950X)。因此,Intel将会发布一款新的10核Broadwell-E CPU,并且之前取消的Broadwell-EX/EP将上市应对Zen。】


P.S.这是个愚人节玩笑。

原作者说AIDA64截图是假的,发布文章时已经有了A0步进工程样品。
图上伪造的ES信息和现在公布出来的A0 8核版一致,当时应该就有了消息

AVX FMA性能较弱,浮点性能大幅增强。
Intel的新闻是真的。
