Does UMA (unified memory architecture) prevent anyone from also adding additional conventional RAM too (apart from what is integrated in the CPU)? Have today's SSD reached RAM's read / write speed?
- ksec 6y agoUMA has nothing to do with the RAM sitting next to CPU, which is what half of this thread is getting mixed up with. They are two different thing. So yes you could have UMA and conventional DRAM, the problem is that there are no DRAM, even with 8 Channel DDR5, capable of feeding enough bandwidth for the hypothetical 128 Core GPU. That is unless Apple decide to use DRAM in additional to HMB or GDDR5 as 2nd layer of Memory.
- webmobdev 6y agoSo is Apple's UMA similar to the nearly 2 decades old SGI O2 UMA - http://www.sgidepot.co.uk/o2/1352.pdf http://www.sgidepot.co.uk/o2/1352.pdf ?
