TSX on Whiskey Lake U

[Nießing__Steffen]

Hi,

I wondered if my Intel i5-8265u could use TSX instructions.

The documentation at https://ark.intel.com/content/www/de/de/ark/products/149088/intel-core-i5-8265u-processor-6m-cache-up-to-3-90-ghz.html says it does not have TSX-NI.

But I read the Intel article about the TAA security issue (https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00270.html) and there this model is listed at the affected CPUs.

I understand the TAA issue that only products with TSX are vulnerable.

So my question is whether the i5-8265u has TSX support or not.

Best regards,

Steffen

Hi Steffen,

not all Whiskey lake support TSX. Only those that are "vPro".

Thanks,

Thanks.

I was just confused because this model was explicitly listed in the article.

Best regards,
