There have been some updates to the rumor specifications for the upcoming RTX 40 Series graphics cards. Kopite7kimi on Twitter is known for providing good information about what the new releases will have to offer. The new rumor brings in updated RTX 4090 specifications, while giving an idea to the RTX 4080 and RTX 4070. A first look at what some less expensive options have to offer.

Although the series of cards has not yet been announced, we expect it to be released in the second half of 2022. With rumors pointing to September / August, we will hear more about what they offer in the coming months. So we will keep you updated on what to expect when it comes.

RTX 40 Series Specifications

From previous rumors, 4090 has had a slight increase in the CUDA cores. Increases from 16,128 to 16,384 cores by upgrading from 126 streaming multiprocessors to 128. While that may not be the full scope of the AD102 GPU, it is what can be expected from the first flagship. Which also comes with 24 GB of GDDR6X memory, with a 384-bit bus clocked at 21 Gbps. All come with a TDP of 450 W, the same as today’s RTX 3090 Ti.

Now for the RTX 4080 specifications, kopite7kimi tells us that it will be made with the AD103-300 GPU variant. This gives the card 80 SMs with 10,240 CUDA cores. And comes with a 256-bit memory bus, but the memory details are where the leak is uncertain. With the option of 16 GB of GDDR6 memory clocked at 18 Gbps. This is possibly questionable since it would be effectively slower than what the RTX 3080 had to offer with GDDR6X clocked at 19 Gbps. But 4080 is expected with an increased TDP of 420 W compared to 320.

Finally, there are some rumors about the RTX 4070 specifications. Expected to use the AD104-275 GPU variant. With 7,168 CUDA cores along with a 160-bit memory bus for 10 GB of GDDR6 memory clocked at 18 Gbps. Although with a much lower TDP compared to the rest with the expected 300 W. The card is also expected to be the latest to be launched with the staggered releases of the Ada series. Starting at 4090 in Q3, 3070 may arrive early in Q4.
