To infinity and beyond? A newly spotted trademark entry shows or at least seems to indicate that Big Navi would get Infinity Cache... AMD Big Navi would get Infinity Cache
Tried to find how much more expensive faster GDDR6X memory is than the one AMD is expected to use. Didn't have luck with that. I wonder if it's just a price reduction technology, or a game changer.
Isn't HBCC just to help with too little VRAM? The problem with the 6000 series, if the rumours (or leaks, like some like to call them) are true, the GPUs might be memory bandwidth starved, not memory amount starved, like some say the 3080, for example, is. But sure, the lesser models of the AMD 6000 ought to have less VRAM, so it might be relevant if it works. However, if this Infinity Cache is to help with the bandwidth issue and is real cache, I wonder where it's physically located.
they have to compete with 16gbps 256-bit against 19gbps 320-bit I bet this will be hit&miss,can't make up for 1.53x bandwidth advantage for competing with a 3070 this may show,at least to some extent at 4K.unless this is hbcc rebranded. gddr6x is nvidia+micron collaboration,amd will never get this.
Didn't know about the collab part, but it must be expensive too (and hot). AMD has to work with what its available. 256-bit is to make it more affordable and competitive, I hope it's enough to not starve the card.
3 exemples that is not an exact logic: AMD: Vega VII vs traditional other "high end" AMD... NVidia: the GTX 960/950 with low gbps and bit, compensate by compression that perform better better than what expected... General computer more AMD but it work with Intel too: it's better to have low CL ram than faster frequency in most of the case A GPU depend more on the whole pack (drivers + GPU + board + technologic used) than focus on spec. It's a bit like race car, i have been in front of many horses (running or prancing) despite having lot less HP and top speed... (but i was way lot lighter, and with smaller tire 14" or 15") So, as the RTX30*0 before, we have to see it in real world before to say if AMD have made good choise or not.
HBM was developed by AMD and Hynix, yet Nvidia also uses it in some professional products. Wouldn't GDDR6X be the same?
Yep. AMD has CDNA now for the compute cards as it split out compute and gaming RDNA. Arcturus (CDNA) is a big evolution over Vega (GCN), while RDNA2 is new architecture, remotely related to RDNA1 in name. And next year RDNA3 is even more drastic ground up designed architecture.
yes,except your expamples don't reflect the scope of this here situation,amd absolutley need that bandwidth,that's why they're introducing this cache - they're lacking bandwidth.
Not another hardware-closed API please... Waiting for DirectStorage, although with 32-64GB RAM system it will not be such huge improvement and I bet in 10 years those APIs will be completely abandoned...
