The rumor mill is abuzz when again as Nvidia’s following-gen Ada Lovelace GPUs draw nearer. Noteworthy tipster @kopite7kimi is offering new particulars in the Twittersphere on what Nvidia has in shop for avid gamers in the tumble. This time around they are shedding some new mild on prime three GPUs in the products stack, which will probably be the very first to start.

In a sequence of new tweets, @kopite7kimi facts the specs for these upcoming GPUs. As has been documented earlier, the flagship die will be Advert102. Curiously, the prime-shelf “Lovelace” GPU will be outfitted with 24GB of GDDR6X working at 21Gb/s. This is the correct similar configuration as the latest RTX 3090 Ti. It ought to be mentioned that the former generation Turing-primarily based Titan RTX also had 24GB of GDDR6 memory. It appears to be that for now, this is as far as Nvidia would like to consider memory allocation on its high-close SKUs. There had been previous rumors that Ad102 may well appear outfitted with GDDR7 memory jogging at 24Gb/s, but people could be incorrect. What is seemingly firmer at this stage is the GPU’s Complete Board Electrical power (TBP). It is at the time once again listed as 600W, which appears like a supplied given that Nvidia wants to thrust this card to the complete greatest level of effectiveness. It could possibly have to in order to fend off AMD for this spherical.

Relocating down the stack we arrive to the RTX 4080. Although the Ampere-primarily based RTX 3080 used a slice-down variation of the flagship die, GA102, that will not be the circumstance for the 4080. In its place of utilizing the huge Advertisement102 die, or the smaller 104 variation like with Turing and former generations, it’s finding its personal slice of silicon. It’ll be an Advertisement103 chip, slotting in in between the major chip on the 4090 and the smaller sized chip on the 4070.

This card is rumored to provide 16GB of GDDR6, which will be a welcome improve for these who imagined the present-day-gen’s 10/12GB was insufficient. Nevertheless, it appears Nvidia will be downgrading the memory from GDDR6X to slower GDDR6. For comparison, the GDDR6X in the recent RTX 3080 operates at 19Gb/s, while GDDR6 can strike about 14Gb/s. It’s possible Nvidia will compensate for this with a wider memory bus, or even additional L2 cache. This GPU will supposedly have the very same TBP as the top-shelf GA102 die, which is 450W in the RTX 3090 Ti.

Eventually, we come to the RTX 4070. This “tween” GPU could be the sweet location in phrases of performance and electric power consumption for the Lovelace architecture. It is noteworthy that for this technology it’ll be having the Ad104 die, which is more substantial than what’s been reserved for this course beforehand. With Turing and previous generations, the 104 die was for the x80 GPU, and the smaller 106 die was for the x70 playing cards. In addition to a greater die it’s also receiving a massive improve in the memory department. It’ll be outfitted (reportedly) with 12GB of GDDR6 operating at 18Gb/s. That is around the identical as the boosted RTX 3070 Ti, which attributes 19Gb/s GDDRX memory. The two 3070 cards only have 8GB of memory even so. Full board electricity is a quaint 300W. That utilized to appear like a good deal, prolonged in the past. Now it’s just about lovely. The leaker notes that neither the RTX 4080 nor the 4070 have started the testing stage. This does suggest the 4090 is previously at that stage.

This era of GPUs promises to be fairly exciting, as both equally Nvidia and AMD are rumored to be unleashing all the things they have in their arsenals. We know that does not audio any diverse from past eras because these two firms have been battling for ages. Having said that, Nvidia likely up to 600W is unquestionably a new matter. It signifies it anticipates some heavy resistance from the AMD and its chiplet-based mostly RDNA3 GPUs.
