Where are the Haswell laptops with TSX-NI ?

JPiga — Wed, 02 Oct 2013 17:38:22 GMT

Hello Intel Community.

I am looking for a laptop with Intel "Transactional Synchronization Extensions New Instructions" - TSX-NI, because I am interested in programming with this feature.

I started by getting a list of Haswell models on this http://en.wikipedia.org/wiki/Haswell_%28microarchitecture%29 Wiki page.

For each model, I visited it's ARK.intel.com page to see if it supports TSX-NI.

Sometimes this information is omitted (e.g. on this http://ark.intel.com/products/76087 i7-4750HQ page), sometimes there is a clear answer - yes/no.

It appears that the following nine models definitely have TSX-NI:

http://ark.intel.com/products/75033 i5-4350U, i7-4650U,

i7-4750HQ, i7-4800MQ,

i7-4850HQ, i7-4900MQ,

i7-4950HQ, i7-4960HQ,

i7-4930MX

What is odd is that I cannot find a single laptop brand using the i5-4350U chip.

Of the other (more expensive) i7 processors, can anyone recommend a 14" model with SSD,

ideally with a touchscreen with more than 768 vertical pixels? I can only find it in the 13.3" Macbook Air.

Thanks!

Ax.Pigafetta, the following link belongs to the datasheet for the Mobile 4th Generation Intel® Core™ Processor Family. I was able to find some processors from your list in this document, however there are some that according to ark.intel.com, they support TSX-NI technology but they are not on the datasheet.

https://www-ssl.intel.com/content/dam/www/public/us/en/documents/datasheets/4th-gen-core-family-mobile-m-h-processor-lines-vol-1-datasheet.pdf https://www-ssl.intel.com/content/dam/www/public/us/en/documents/datasheets/4th-gen-core-family-mobile-m-h-processor-lines-vol-1-datasheet.pdf

I'm going to double check this information in order to find out the correct list of processors that support TSX-NI.

We do not handle information about which companies are using the specific processor you mentioned. You would need to contact them to get that information.

Thanks Sylvia.

It appears that the ARK website has been updated and now (as of 2013 Nov) shows that e.g. the http://ark.intel.com/products/76308 Intel Core i5-4300U does support TSX-NI.

The i5-4300U is now available for example in the Thinkpad T440 and T440s here:
