Tencent cloud AMD Cloud servers are Tencent cloud The first one is not Intel CPU The server . I've been feeling lukewarm all the time . But it's cheaper after all . And I've always had a lot of friends about AMD The server also has some skepticism . Today, I will analyze this server , With the common Standard S2 Let's make a comparison and see how , Which good .
Tencent cloud AMD Cloud servers and standard Intel The server ：
2.0GHz AMD EPYC 7551 processor ,Turbo frequency 2.55GHz
2.4 GHz Intel Xeon Processor
The latest generation of eight channels DDR4 Memory , The memory bandwidth is up to 2666 MT/s
The latest generation of six channels DDR4 Memory , The memory bandwidth is up to 2666 MT/s
Instance network performance corresponds to specifications , The higher the specification, the better the network forwarding performance , The higher the upper limit of Intranet bandwidth .
With network enhancement , Packet forwarding capability up to 30w, Maximum intranet bandwidth can support 10Gbps
AMD Cloud servers use cheap AMD CPU,CPU performance 100% unlimited , use AMD EPYC Xiaolong processor , Provide a balance calculation 、 Memory and network resources , The cost of building a station is the first choice Tencent cloud AMD Cloud server .
AMD Cloud servers include SA1 And the new generation SA2 example . From the official specifications ,SA2 Used AMD ROME CPU, stay CPU performance 、 Server comprehensive performance 、 Network performance ratio SA1 All of them have been improved .
Standard SA2 Of CPU The performance is more than 30% higher than that of the previous generation , Computing performance has been greatly enhanced , In practice, there is a better user experience .
Standard SA2 The memory bandwidth of , So data flow is fast , A large amount of data can be stored at the same time , Configure the top configuration CPU, Further improve the operation speed , The user experience is that this model has a fast response .
It is worth mentioning that Tencent cloud Yes AMD The memory of the server is specially optimized , Both models use memory bandwidth of up to 2666MT/s A new generation of DDR4, Use 8 passageway . This is stronger than Intel The server .
networking SA1 The intranet only has 1.5Gbps Broadband , There is no value written in the network , Because it was the first generation of servers , The estimates are very small . and SA2 The biggest support 25Gbps,750 ten thousand PPS Ability to receive and contract , These data show that SA2 Is very good at network data work , In the same business environment ,SA2 The ability to process network data streams is much better than SA1.
For specific specifications, please refer to Official documents
How to choose
1、 first generation SA1 The main frequency of the model is low , Network performance is a little bit poor , Users with strict business requirements are not recommended to choose .
2、 Second generation SA2 Model from CPU、 Memory 、 Network performance and other aspects have been enhanced , It's about computing in real life 、 Network and other services use this model faster .
Users consider the business requirements when choosing 、 Server performance 、 The cost of the three , You can choose what suits you .
