Its a new day and we have yet another roadmap and this time it suggests that the upcoming 9th generation CPUs will be coming out in October. Here we are going to look at something else. If you recall, Intel showed off a 28-core Cascade Lake-X CPU that was running at 5 GHz on all cores at Computex 2018.
While this Intel 28-core 5 GHz Cascade Lake-X CPU caught the attention of many, it seemed to be too good to be true and it turned out that it was all a fake. The chip was nothing new, it was an older chip that was being used. Other than that the CPU was cooled using an industrial cooler. To add the cherry on top, Intel “forgot” to mention that the chip was overclocked.
If you think about it, having 28 cores running at 5 GHz is pretty hardcore even from Intel. Now that we have a new roadmap, it seems that Intel is giving up on the dream. The roadmap mentions that the upcoming core-x CPUs will feature up to 18 cores. While that is competitive and I am sure customers on the corporate side will appreciate the 18 cores, 28 cores would have been better.
It seems that Intel has given up on the dream of bringing the Intel 28-core 5 GHz Cascade Lake-X CPU to market. Otherwise, we would have learned something about the upcoming processor any of the 3 roadmaps that have leaked recently. The idea of an Intel 28-core CPU running at 5 GHz on the current architecture was stupid at Computex 2018 and so is it now. It seems that Intel has realized that as well. Some of the images of the roadmaps have bee included below for you to check out.
It will be interesting to see what Intel has to say regarding the matter. While I have not doubt that a 28-core 5 GHz CPU can be done, Intel will need to change the architecture in order to make that work. Other than that, I am pretty sure it will take a few years before a CPU like this can be introduced into the market and it can run using conventional cooling solutions.
Getting commercial cooling for a 28-core 5 GHz Cascade Lake-X CPU is just too expensive. Keeping in mind that the processor itself is not going to be cheap. Intel does charge a huge premium for higher core counts and I am sure that Intel will not make an exception in this case. Having that said, it should be interesting to see what Intel is going to bring to the table.
While we know that 8 core CPUs are around the corner, we also know that they will be based on the old 14nm process that has been around for a while, so do not expect to see huge gains in performance and IPC.
Let us know what you think about the 28-core 5 GHz Cascade Lake-X CPU and whether or not you think it is even possible to make something like that.
