        Hi Ivan,
        Thanks, I saw that link.
        Unfortunately, it doesn’t contain info about GPU model (I’d like to know the exact model, not just “Intel 500 series”), eDRAM availability and amount, and EPT feature.

         

        This forum says you’re working for Intel.
        If that’s correct, can’t you find the answers within Intel?
        After all, the company manufactures and sells the chips.
        I’m sure some people inside Intel should know it’s exact specifications.

         

        Thanks in advance.

         

        Regards,
        Kosta.

          Acer would have the specifications as well.  Have you contacted them for detailed specifications on their undocumented laptop?

            I did, only got the same link to cpu-world.

             

            Intel is making the CPUs, not Acer.
            Why do you think Acer knows the answers to my questions?
            My questions are about what’s inside the chip. Acer can’t get in there.

              I am not going to belabor the point.  Acer cannot make a laptop or bios without having detailed specs on the processor.  Intel has already told you they cannot find it in their database.  There is no documentation on this laptop on the Acer site.  There is no support page on the Acer site for manuals, documentation, drivers, or bios updates.

               

              If you do get this laptop, where will you find support for it?

               

              I would move on to a laptop that has the proper support, regardless of the "deal" on the one you have selected.

                Have you ever built a PC?
                I did several times, and succeeded without detailed specs on the processor.
                Don't see a reason why Acer might care about e.g. EPT feature.

                 

                BIOS is deprecated and no longer used in modern systems.
                As for UEFI firmware, Acer doesn’t develop it.
                In those laptops, they use the firmware made by a third party, namely by Insyde Software.

                 

                But even if you’re right, and Acer knows the answers, I’d still like to get an answer from Intel.
                Intel designed and manufactures those chips.

                Intel knows more about them than any company that integrates them, solders them, or develops software for them.
                Therefore, information from Intel is the most accurate.

                  "Have you ever built a PC?"    More than you can imagine.

                   

                  Yes, when referring to the bios, I was referring to UEFI.  But, thank you for thinking I was incorrect.


                  You have already received an answer from Intel.  You just did not like it.

                   

                  And, you have not considered that this could be a fraudulent processor, or one Intel made specifically for some integrator, in which case it is the responsibility of the integrator to help you.

                   

                  I am no longer following this thread.

                    I’m totally agree with you Al Hill, Acer cannot make a laptop or bios without having detailed specs on the processor. The information that I gave to ConstMe is the information I could find, there is not more information I can give you, if you need more information try contacting Acer, if they don’t have this information, you will need to consider that this could be a fraudulent processor as Al Hill has already mentioned above.

                      Hi Ivan.

                       

                      Being a public company, Intel corp. has an official investor relations web site, http://www.intc.com.
                      On that web site, there’s a page “Processor Price List”: http://www.intc.com/priceList.cfm
                      On that page, there’s a link to the PDF with the current price list.

                       

                      In the “uLV Intel® Core™ i3 processor Mobile (FCBGA10)” section, the price list says following:

                      i3-6157U (3M cache, 2 Cores, 4 Threads, 2.40 GHz, 14nm)
                      Jul'16 (07/17) Price: $304
                      Aug'16 (08/30) Price: $304

                       

                      Do you have reasonable explanation how the “fraudulent” CPU ended in that table? :-)

                       

                      Regards, Kosta.

                        As I have mentioned before this is a tray processor and the best support and answer will be provided by the laptop manufacturer.

                        They are not sold to customers only to OEMs for them to integrate them in their systems.

                          Apparently, that undocumented i3 indeed supports virtualization. Haven't tested yet, but at least Windows 10 task manager says "Virtualization: Enabled" on the CPU tab.

                           

                          And just like i3-6167U, the i3-6157U features Intel Iris 550 GPU with 64 MB eDRAM, that's used by GPU but also serves as L4 cache.

                          Here’s some details from CPU-Z:

                          L1 Instruction cache 2 x 32 KBytes, 8-way set associative, 64-byte line size

                              Eventually, Intel disclosed the specifications of the chip.

                              BTW, I wrote to their investor relations e-mail asking why there’s an undocumented CPU on the price list. Which might be the reason why they decided to open the spec.

                                Maybe you can get ACER to document this laptop now, as well as providing drivers for it.

                                  I don’t need anything from Acer.

                                  I did clean install of Windows, replacing SSD and changing OS language from German to US English.

                                  As I expected, the laptop does not need any drivers except what is included in Windows 10 and available on Windows update.
