这不是虚拟化吧

lz 对虚拟化有什么误解吧,Rosetta 是二进制转换,不是虚拟化……

@vk42 对的,只能说 Rosetta 以及其底层技术 NB,Apple 当初推 LLVM/clang,可是布局了很多年了。

我就奇怪为什么 gb 都跑了这么多记录出来了,cb 怎么一个记录都不放出来,搜了一圈只有 DTK 那颗 a12z 的 cb r23 分。

猜想可能是没到成绩解锁时间,但是 gb 就偷跑的这么明目张胆嘛,还是说因为 gb 跑的好看所以就放任偷跑了 😂

看了个评论
What I meant was that their document describing the v4 tests[1] mentions SSE and AVX, while the v5 version[2] does not. Does it mean that the v5 tests don't cover them? I found find it surprising for a benchmarking tool but they really were mentioned before and now they're not, hence my question. If indeed v5 tests are not particularly about specialized performance but more about real-world use cases (e.g. PDF rendering, SQLite, image compression as others have mentioned) then running Geekbench v4 on M1+Rosetta would give a comparison of emulated x86 without vector instructions versus native x86 with all of its modern capabilities. Now if the M1 wins that… [1] https://www.geekbench.com/doc/geekbench4-cpu-workloads.pdf [2] https://www.geekbench.com/doc/geekbench5-cpu-workloads.pdf 他看了 geekbench 的官方文档,推测 geekbench4 用了 intel 的 avx 等指令集,但是到了 geekbench5,文档反而不提这些指令集了,如果不使用 avx512 等指令集,那么 intel 的测试分数会极大受到影响,所以表现得不如 M1 芯片。。。 |

我看了下 geekbench4 里有几个手工写的汇编程序,测试 cpu 的性能,到了 5 都去掉了,那么 5 的测试代码,跑的是普通 C/C++编译结果,还是手工优化的代码,那就不知道了。

@bookit 不用特有指令集其实更接近日常使用应用场景,而且这样算是把两个平台拉到同一个水平线上比较。除非 gb 的测试样例是明显偏向 AS 优化,不然也没啥问题吧

什么意思?
arm 转译 x86 吊打原生 x86 ? 还是 arm 转译 x86 吊打虚拟化后的 x86 ? |
