Kaby lake vmware fusion 101/1/2024 ![]() ![]() There are many who say we are running out of the benefits of parallelization for CPUs and that soon, adding cores won’t get us much in terms of added performance. In the old days, when Dennard scaling still allowed chip makers to crank the clock speed on ever-shrinking circuits, we could get more performance that way, But somewhere between 4 GHz and 5 GHz, depending on the architecture, increasing the clock speed made chips a lot hotter, and we had to use Moore’s Law advances to make machines and their applications more parallel rather than clock higher to get more work done. It just is taking longer to make each step, even if the steps are bigger. ![]() Everyone took this to mean that the pace of advances had slowed, but as Intel painstakingly argued last week in its first-ever Technology and Manufacturing Day, the chip maker is on the same course of halving the cost of transistors every two years that Moore’s Law predicts. It was stretching from two years to two and a half and then looking like three when Intel conceded that it was getting tougher to shrink transistors and master the manufacturing processes to put the smaller devices into production on increasingly capacious chips. Intel conceded back in the summer of 2015 that the Moore’s Law advance in chip manufacturing processes was changing, with it taking more time to do a transistor shrink than has been the case for more than 40 years. The Kaby Lake chips are Intel’s third generation of Xeon processors that are based on its 14 nanometer technologies, and as our naming convention for Intel’s new way of rolling out chips suggests, it is a refinement of both the architecture and the manufacturing process that, by and large, enables Intel to ramp up the clock speed on the prior generation of devices and, in the case of Kaby Lake specifically, support faster DDR4 main memory than prior Xeon E3 chips as well as the shiny new non-volatile 3D XPoint Optane memory sticks and Optane SSDs, both of which debuted in March. Ideally it would be better to mask the host CPUID in this scenario as the actual capabilities resides in the host CPU.The tick-tock-clock three step dance that Intel will be using to progress its Core client and Xeon server processors in the coming years is on full display now that the Xeon E3-1200 v6 processors based on the “Kaby Lake” have been unveiled. Somehow the method to mask the host CPU ID doesn't seem to work (instead of cpuid, it would be cpuidMask.1.eax). I'd be curious to see the vmware.log of the VM that has this VPMC problem and see whether the same problem exists and whether Fusion identifies the VPMC capabilities of the host CPU properly.Īs a possible workaround, you could try masking the CPUID of the guest VM and see whether the VPMC problem gets resolved. host CPUID guest codename: Pentium Core - Unknown codename | vmx| I125: hostCPUID codename: Pentium Core - Unknown codename Those with Kaby Lake processors would have these lines. But looking at vmware.log files in this forum, it seems that VMware Workstation/Player does not identify the codename of the Kaby Lake processors properly although it does seem to identify its features/capabilities properly (e.g. I don't have a Kaby Lake processor machine. ![]()
