Nvidia’s RTX 4000 get new specs, and it is not all excellent news

Nvidia’s upcoming Ada Lovelace graphics playing cards simply acquired a brand new set of rumored specs, and this time round, it’s a little bit of a blended bag.

Whereas the information is nice for one of many GPUs, the RTX 4070 truly acquired a lower relating to its specs — however the leaker says this received’t translate to a less expensive worth.

And TBP, 450/420?/300W.

The knowledge comes from kopite7kimi, a well-recognized identify relating to PC {hardware} leaks, who has simply revealed an replace to the specs of the RTX 4090, RTX 4080, and the RTX 4070. Whereas we’ve already heard earlier whispers concerning the specs of the RTX 4090 and the RTX 4070, that is the primary time we’re getting predictions concerning the specs of the RTX 4080.

Let’s begin with the excellent news. If this rumor is true, the flagship RTX 4090 appears to have acquired a slight bump within the core depend. The beforehand reported quantity was 16,128 CUDA cores, and this has now gone as much as 16,384 cores, which interprets to an improve from 126 streaming multiprocessors (SMs) to 128. As for the remainder of the specs, they continue to be unchanged — the present expectation is that the GPU will get 24GB of GDDR6X reminiscence throughout a 384-bit reminiscence bus, in addition to 21Gbps bandwidth.

The RTX 4090 contains the AD102 GPU, which maxes out at 144 SMs, but it surely appears unlikely that the RTX 4090 itself will ever attain such heights. The total model of the AD102 GPU might be going to be present in an excellent higher graphics card, be it a Titan or just an RTX 4090 Ti. It’s additionally rumored to have monstrous energy necessities. This time round, kopite7kimi didn’t reveal something new about that card, and as of now, we nonetheless don’t know for a incontrovertible fact that it even exists.

Transferring on to the RTX 4080 with the AD103 GPU, it’s mentioned to return with 10,240 CUDA cores and 16GB of reminiscence. Nevertheless, in accordance with kopite7kimi, it will depend on GDDR6 reminiscence versus GDDR6X. Seeing because the leaker predicts it to be 18Gbps, that will truly make it slower than the RTX 3080 with its 19Gbps reminiscence. The core depend is precisely the identical as within the RTX 3080 Ti. To this point, this GPU doesn’t sound very spectacular, but it surely’s mentioned to return with a a lot bigger L2 cache that might doubtlessly provide an improve in its gaming efficiency versus its predecessors.

On the subject of the RTX 4070, the GPU was beforehand rumored to return with 12GB of reminiscence, however now, kopite7kimi predicts simply 10GB throughout a 160-bit reminiscence bus. It’s mentioned to supply 7,168 CUDA cores. Whereas it’s definitely an improve over the RTX 3070, it won’t fairly be the generational leap some customers are hoping for. It’s additionally supposedly not going to obtain a worth low cost primarily based on the discount in specs, however we nonetheless don’t know the MSRP of this GPU, so it’s onerous to guage its worth.

Lastly, the leaker delivered an replace on the facility necessities of the GPUs, which have definitely been the topic of a lot hypothesis over the previous couple of months. The anticipated TBP for the RTX 4090 is 450 watts. It’s 420 watts for the RTX 4080 and 300 watts for the RTX 4070. These numbers are much more conservative than the 600 watts (and above) that we’ve seen floating round.

What does all of this imply for us — the end-users of the upcoming RTX 40-series GPUs? Not an excessive amount of simply but. The specs could but change, and though kopite7kimi has a confirmed monitor document, they could possibly be mistaken concerning the specs, too. Nevertheless, as issues stand now, solely the RTX 4090 appears to mark an enormous improve over its predecessor whereas the opposite two are a way more modest change. It stays to be seen whether or not the pricing will mirror that or not.
