Let the old CPU freshman AMD introduce the technical characteristics and advantages of DX12

AMD explained in detail the two main features of DX12 today-asynchronous shades and multi-tHREADED Command Buffer ReCording.DX12 promises to "rejuvenate new life" for the old multi -core CPU, and these two main functions are the main factor that allows these CPUs to rejuvenate energy.

The first is the asynchronous color device. This new technology promises to bring 45%of performance improvement.Followed by a new feature, it is called a multi -threaded command buffer record, which has the potential as well as an asynchronous color device.The previous DX versions were limited to single and string queues for processing different loads.Therefore, graphic processing, calculation, and memory replication operation can only be activated and start work after the processing of other lines is completed.This has caused hardware to be idle for a period of time, affecting performance.

With the support of DX12, the asynchronous color device can accelerate the completion of the task. The compatible AMD graphics processor can perform these tasks alternately between different threads, thereby shortening the rendering time.The shorter rendering time reduces the delay of the pipeline of the graphic processor.The delay is equal to better performance.Performance means a better response in virtual reality in virtual reality.

Multi -threaded command buffer records can also bring a lot of performance improvement.AMD said that this new technology (multi -threaded command buffer record) will bring huge improvements to games that support DX12.The 5 key points of this technology are as follows:

By handling the driver and API to the CPU processing, overhead (overhead) can significantly reduce

The absolute time to complete the complex graphic will be significantly reduced

Game load can be targeted to 4 CPU cores

The new bandwidth of the CPU can make the Draw Call higher peak, which can bring more detailed and realistic gaming world.

All CPU cores can now "talk" with the graphics card at the same time

In short, I think these special technologies can work together and complement each other.The resources that can use the graphics processor more effectively, faster, and intelligently means that any GCN graphics card today, and the 7000 series and the subsequent graphics card can get considerable performance improvement after turning from DX11 to DX12.
