Evaluate performance of MediaTek Helio X20


Some smartphone/tablet have been using MediaTek Helio X20 as its CPU (like Xiaomi Redmi Note 4), so I write this post to evaluate the performance of that chip, so that you can consider it is worth to buy that smartphone/table or not!

  1/ In below Vietnamese site, X20 is a little bit better than Snapdragon S10

(I think this review is a PR of X20, which is not correct about the Antutu score and other aspect)

2/ But in this post from techgrapple.com, the X20 is actually a "Medium" processor, which is not really good:

Helio X20 vs Snapdragon 652 vs 650 vs Apple A8

3/ This details review from candytech.in should be the most correct and useful source of information:

Mediatek Helio X20 Vs Snapdragon 820 vs Exynos 8890 (Compared)

GeekBench Multi Core 700655916269
Antutu Benchmark91252136251129866

Hence, in conclusion, the Mediatek's Helio X20 is a good chip, but in the 'Medium' range only for performnace. It is not the top performance chip like some PR review say, but it is cheap, which is required for 'medium' smartphone. You don't want to spend a lot for a phone, Helio X20 chip would be a smart choice.

[sapui5] Best Practice in sapui5 development

Hình ảnh
Hi, Small Tips but no many knows: - Use this.getResouceBundle().getText(sKey, aParam) - Use BaseController (instead of creating a Util service). - Odata Model resetChanges() & submitChanges() ('TwoWay' binding required). Allow TAB to navigate within a table: Use property " keyboardMode " of ListBase . Set it to value " sap.m.ListKeyboardMode.Edit " and it would allow users to use TAB to move to the next cell in a table (the same behavior in MS Office table). API: https://sapui5.hana.ondemand.com/sdk/#/api/sap.m.ListBase/controlProperties https://sapui5.hana.ondemand.com/sdk/#/api/sap.m.ListKeyboardMode/overview References Advanced JS technique to shorten your code: Below hand-on with explanation will help you to shorten your frontend code a lot. Make the code more succinct, readable & easier to maintain. Functional Programming for your UI5 Apps Hands-On Worksheet Keep in mind the mindset: Think "everythin...

Implement Search field with case-INSENSITIVE by SAP UI5

Hello guys, Continue to read if you're sapui5 developer, or you work closely with UI development. At the time I write this post, SAP UI5 and Odata does not support filter with case sensitivity. Odata provide some filter parameter that help you to filter with case-INSENSITIVe. However, you hardly modify the URI of ODATA service in your font end SAP UI5 code. Most of us use API provided from SAP , we only provide the parameter to API function, then let the API from SAPUI5 library handle the ODATA service URL. In short, I mean we cannot, or hardly, modifying the odata GET request as we want, but use the standard API instead. Return to the main topic, we need to write a function to filter the ODATA get request so that we get the returned data filtered as the way we want (filter with case-INSENSITIVE). For example: you type " test " in the search field, then you should get the results with all the entries containing "test", or "Test", or "TES...

[sapui5][abap] Use Eclipse to push code to ABAP repository (temporary)

Hình ảnh
Hi, For now, local SAP Web IDE cannot be used to push code to ABAP repository. So we have to use Eclipse as a workaround. This post we will make a tutorial to do that. 1. Setup Eclipse environment: - Get Eclipse as described in this link . - If your company use firewall, you may have an error connecting to the Internet when "Install new software...". In that case, please use network proxy to access the internet ( should ask your IT department the proxy server information ): You can check whether the software gets installed or not by checking in Help/About : 2. Connect to ABAP repository using SAP GUI: Make sure that the connection is ready & on so that you can connect easily using Eclipse. - Open SAP GUI. - Check if your connection is working, if not; create a new connection to your server: Create new connection Input server information to connect to NOTE: in case your eclipse still cannot see the connection (eg. C46), you need to m...
