20 Nanometer Node Remains Broken for GPUs - 2022 To See Mostly 28nm Products

A particularly interesting editorial over at PC Perspective was recently published - one I don't experience the slightest regret, echoing here. The write upwardly, simply put, is basically an aggregation of process updates and so far and compounds on the in-feasibility of the 20nm process every bit a viable base for the Republic of the fiji islands XT GPU. AMD rolled out Tonga on the 28nm node concluding year, so the probability of Republic of the fiji islands XT being on the 28nm is pretty significant. We already know Fiji will characteristic HBM retention on board via an interposer, simply just how a process compress is going to fit in (if at all) with the yard scheme of things remains to be seen.

20nm GPUs remain just equally infeasible as always - 2022 to be the domain of 28 nanometer

The prime number argument confronting the 20nm process is one our readers should be pretty familiar with now (seeing its extensively used in our comments department) - that of Silicon Border's wafer calculator ( a neat little program that calculates the amount of usable dies on a round wafer given a specified die size and procedure node.) The editorial pointed out that at the size that Fiji is purported to be, AMD will be seeing approximately 98 usable dies if the size turns out to exist 550mm^2 (on a 12 inch wafer). This number volition increase significantly if the dice size is lower and yield will subtract the number if the procedure is lower.

There take been multiple rumors of AMD expanding its wafer contracts and of TSMC loosing a pregnant portion of its 28nm customers. At this signal, both 20 and 28nm process are more than or less as probable (in my opinion) where the Fiji XT GPU is concerned. This is not because of existing evidence, only because of company claims themselves. However, hard evidence is very hard to argue confronting, and this is why PCPer's ed makes such an impact. It notes transistors per square mm and how AMD has been able to push upwards the corporeality of transistors on a dice of a given size past alot.

To be honest, the evidence is very much stacked confronting AMD bringing out a 20nm GPU - everything from heat dissipation to clocks becomes a problem. As the commodity rightfully points out, Intel the absolute giant of the silicon Industry stumbled at the sub 20nm node - so physics is about to get a real problem for foundries very fast. Information technology also means that speaking in terms of sheer practicality, 28nm HKMG would exist perfect for a loftier terminate, water cooled GPU. Ofcourse, that would mean AMD would need to work on its architectures solely, or go with the 20nm process and allow the consumers suffer lower than normal clock rates.
