The rumor mill is abuzz once once more as Nvidia’s upcoming-gen Ada Lovelace GPUs draw nearer. Noteworthy tipster @kopite7kimi is giving new facts in the Twittersphere on what Nvidia has in store for avid gamers in the slide. This time all-around they are shedding some new light on top rated a few GPUs in the item stack, which will possible be the initial to start.

In a series of new tweets, @kopite7kimi details the specs for these forthcoming GPUs. As has been claimed beforehand, the flagship die will be Advert102. Interestingly, the best-shelf “Lovelace” GPU will be outfitted with 24GB of GDDR6X jogging at 21Gb/s. This is the specific same configuration as the present-day RTX 3090 Ti. It really should be observed that the earlier technology Turing-based mostly Titan RTX also had 24GB of GDDR6 memory. It appears that for now, this is as much as Nvidia wishes to acquire memory allocation on its superior-finish SKUs. There have been earlier rumors that Advertisement102 could appear equipped with GDDR7 memory working at 24Gb/s, but all those could be incorrect. What is seemingly firmer at this stage is the GPU’s Overall Board Electric power (TBP). It’s after yet again detailed as 600W, which would seem like a offered given that Nvidia wants to press this card to the absolute highest stage of overall performance. It may well have to in buy to fend off AMD for this spherical.

Transferring down the stack we arrive to the RTX 4080. Whilst the Ampere-based RTX 3080 utilized a minimize-down model of the flagship die, GA102, that won’t be the scenario for the 4080. Alternatively of working with the major Advert102 die, or the scaled-down 104 model like with Turing and past generations, it is acquiring its possess slice of silicon. It’ll be an Advertisement103 chip, slotting in amongst the big chip on the 4090 and the scaled-down chip on the 4070.

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

Eventually, we occur to the RTX 4070. This “tween” GPU could be the sweet location in conditions of effectiveness and electrical power usage for the Lovelace architecture. It is notable that for this generation it’ll be receiving the Advert104 die, which is bigger than what’s been reserved for this class beforehand. With Turing and preceding generations, the 104 die was for the x80 GPU, and the scaled-down 106 die was for the x70 playing cards. In addition to a bigger die it’s also acquiring a massive enhance in the memory division. It’ll be outfitted (reportedly) with 12GB of GDDR6 jogging at 18Gb/s. That is roughly the identical as the boosted RTX 3070 Ti, which functions 19Gb/s GDDRX memory. Both of those 3070 cards only have 8GB of memory having said that. Overall board energy is a quaint 300W. That used to seem like a large amount, long ago. Now it’s virtually lovely. The leaker notes that neither the RTX 4080 nor the 4070 have started the screening stage. This does indicate the 4090 is by now at that stage.

This period of GPUs guarantees to be fairly attention-grabbing, as the two Nvidia and AMD are rumored to be unleashing anything they have in their arsenals. We know that doesn’t seem any unique from past eras considering that these two companies have been battling for ages. Nonetheless, Nvidia heading up to 600W is definitely a new thing. It implies it anticipates some hefty resistance from the AMD and its chiplet-based RDNA3 GPUs.
