Le 11th Generation Intel Core CPU desktop – codename Rocket Lake – will only arrive in the course of March , but there are those who are already having fun testing the limits. In two videos posted on Twitter by the VWorld account, we see a future Intel processor with 8 cores and 16 thread struggling with an extreme OC attempt under liquid nitrogen.

It is not clear who the author of the video is, but the video shows that the processor was tested on a motherboard from Gigabyte , possibly a Z chipset model 590, along with other information. The first is that the CPU in question has been overclocked to 6923 MHz . To prove that it is a Rocket Lake processor, some details: the size of the L1 and L2 caches, respectively 48 KB and 512 KB, within the cores Cypress Cove, as well as AVX instruction support 512 F and SHA, not supported by current Comet Lake CPUs tenth generation.

In a second video it is also seen that on the same platform the memory has been brought to 6666 MHz with an operating voltage of 1, 83 V. We remind you that in the coming days at CES 2021 Intel should announce the new motherboards with the series chipsets 500 and LGA socket 1200. For the CPUs, however, we will have to wait until March. The new Rocket Lake solutions, compatible with both the platforms of the series 400 and future chipsets 500, will offer up to 8 cores and 16 thread .

Products again at 14 nanometers , these chips will be the first Intel desktops to adopt a new architecture in more than five years now: Intel talks about cores Cypress Cove , an adaptation of the Sunny Cove architecture that we have already seen on Ice Lake mobile chips at 10 nanometers. The CPUs will also be fully compatible with PCI Express 4.0 and will support DDR4 memory – 3200. As for the graphics , Intel will adopt the new architecture Xe LP , a clear step forward compared to the Gen 9.5 seen on previous models. A increase in CPI is expected between 10% and the 20% from the new compute architecture, and this should be particularly useful in gaming and some workloads.
