I have an application that have intense query to SQL Server database utilising SQLDataReader. The problem when built and executed on Windows 10 64 bit on two platforms, the performance differ greatly.
在构建带有Radeton(tm)HD Graphics(4 CPUS)的AMD A10-5745M APU时，该应用程序在每个Windows主机上运行缓慢.但是，当使用Intel®Core™i5-4200M CPU @ 2.50GHz(4个逻辑CPU)进行编译时，它在每个Windows主机上的运行速度都非常快.
When built AMD A10-5745M APU with Radeton(tm) HD Graphics (4 CPUS), the application run slowly on every Windows hosts. But when compiled with Intel(R) Core(TM) i5-4200M CPU @2.50GHz (4 Logical CPUS), it runs very fast on every Windows host.
二者均使用Visual Studio Community 15 Update 2在.NET Framework 4.5.2中进行编译.

推荐答案
实际上，此问题与您的硬件有关.
Actually, this issue more related to your Hardware.
从我这一方面来说，我可能会有所偏见，但是我一直对英特尔CPU的寿命感到幸运. AMD以前曾是一个严重的竞争对手，但多年来质量一直在下降，而且他们似乎并没有跟上速度/功能部门的步伐. 您还可以检查 AMD A10-5745M与Intel Core i5-4200U 以获取更多详细信息.
From my side, I might be biased, but I have always had better luck with the lifespan of Intel CPUs. AMD was a serious competitor before, but their quality has dropped over the years and they don't seem to be keeping up in the speed/features departments. You can also check AMD A10-5745M vs Intel Core i5-4200U for more details.
