opencl 1.2 et carte ati 4870 (rv770)

Bonjour j'aimerais savoir si les cartes ATI 4870 (rv770) son compatible avec l'opencl 1.2.

J'ai déjà découvert qu'elle ne l'etait pas avec l'opencl 1.1.J’espère qu'elle le seront avec l'opencl 1.2.

Si elle sont compatible pourquoi moi je reste bloquer a la version 1.0 alors que j'ai mis les pilotes 12.4 compatible avec la version 1.2

et que j'ai installer ceci:

AMD-APP-SDK-v2.6-Windows-64.exe (208.8 MB)

Je suis sous windows 7 64 bits

cordialement.

The same but in english

Hello I wonder if the ATI 4870 (RV770) compatible with its OpenCL 1.2.
I've found that it was not with the OpenCL 1.1.J hope she will be with the OpenCL 1.2.
If it is,why I remain consistent block is version 1.0 while I put the 12.4 drivers compatible with version 1.2
and I install this:
AMD-APP-SDK-Windows-v2.6-64.exe (208.8 MB)
I have windows 7 64 bit

cordially.

But on this page is marked as beta of OpenCL 1.2 is compatible with the 4870 cards.

this means that the registered Trademark is for version 1.0 does not support it not in beta test version 1.2.

But is  was write

Devices with Beta Level Support:2

ATI Radeon™ HD

4800 Series (4890, 4870 X22, 4870, 4850 X2, 4850, 4830)

So i think the beta 1.2 was supported

No?

Version 1.0 of OpenCL is that it came out longtemp so it is no longer in beta.
So the only beta that speaks this page is version 1.2 so the card should support well the beta version 1.2 is no?

and here was the list of the card compatible.

I'm sorry but I do not understand can be a cause of the phenomenon of translation.
7XXX devices supports version 1.0 that I comrpis.
But not the rest.
Is one day version 1.1 or 1.2 of OpenCL will be 7xxx devices compatible with

RV7XX(Most HD4XXX and some HD5XXX) devices will never support OpenCL 1.1 or 1.2, they don't have the hardware to satisfy the requirements of OpenCL.

This is Different than HD7XXX devices, which will support OpenCL 1.1/1.2.

I understand
thank you for your help.
cordially
