CPU-Z 1.88 adds Intel 9th gen R0 stepping CPUs, AMD 3000-series APUs support

CPUID updates its CPU-Z to 1.88 firmware version which adds the upcoming Intel R0 stepping and 9400F, 9600KF, 9700KF and 9900KF. Interestingly, it also provides preliminary support to AMD 3000-series ‘Picasso’ APUs. Other updates include DDR4 chips manufacturer details, detection for AMD Radeon VII and GTX 1660/1660 Ti.

Intel introduced the F and KF series earlier this year in January. The key difference in the KF and F versions are the absence of the integrated iGPUs. Initial variants were Core i3-8100F, Core i5-9600KF, Core i7-9700KF and the Core i9-9900KF. The Intel B365 chipset was also released with it.

About the Intel R0 stepping…

There is no information about the benefits of R0 stepping. The new Intel R0 stepping is expected to have performance tweaks and better silicone to provide a better overclocking potential. It is significant enough to have the user to update its compatible motherboard’s UEFI to avoid any Windows 10 crash. According to manufacturers, you still can update the UEFI with R0 stepping to flash the update. This way you won’t need to carry the hassle of flashing the motherboard with an older stepping just to use the R0 stepping, but it would be best if manufacturers start providing motherboards with pre-flashed UEFI.

Updated chipset and CPU variants

The updates should be rolled out for Z390/ H370/ Q370/ B365/ B360/ H310 series motherboards from all manufacturers. MSI would have the new UEFI on the 2nd of April. The R0 steppings will be implemented on a series of Core i5, Core i7 and the Core i9 CPUs, starting from the Core i5-9400T to Core i9-9900K.
