Well-known kopite7kimi from Nvidia leaker has shared possible new specifications for the first GeForce RTX 40 video cards. Specifically, this concerns the alleged RTX 4090, 4080 and 4070 cards. The first of these video cards is expected to appear later this year.
Kopite7kimi, who in the past has regularly shared correct information about Nvidia GPUs, Posts information on Twitter About RTX 4090, RTX 4080 and RTX 4070 possible. According to the link, the RTX 4090 will receive the AD102-300 GPU, which will be based on the Ada Lovelace architecture. The GPU should have 16,384 CUDA cores, which corresponds to 128 multiprocessor streaming processors. In addition, the video card will receive 24 GB of GDDR6X memory at 21 Gbit / s and with a 384-bit memory bus. That would correspond to a memory bandwidth of 1008 GB/s. The Total plate strength It is expected to be around 450 watts.
According to kopite7kimi, the GeForce RTX 4080 will have an AD103-300 GPU with 10240 CUDA cores spread over 80 SMS. The video card gets 16GB of memory on a 256-bit memory bus, but this may not be faster than the GDDR6X modules. The leaker mentions that the video card may receive 18Gb/s GDDR6 memory, but he wonders about that himself. For example, the current RTX 3080 has 19Gb/s GDDR6X memory. The tbp of the RTX 4080 will be 420W.
The GeForce RTX 4070 should also get an AD104-275 GPU with 7168 CUDA cores. In addition, the video card will receive 10GB GDDR6-18Gbit / s memory on a 160-bit memory bus. Previous rumors mentioned that the video card will get 12 GB of memory and a 192-bit memory bus. The tbp for that card is expected to be around 300W.
Rumors have been circulating for some time about the upcoming RTX 40 series expected later this year. For example, cards are expected to get Much larger amount of L2 cachewhich may also explain the alleged low memory speeds of the RTX 4080 and 4070. Founders Editions are also expected to get New PCIe Gen5 power connector†
According to previous rumors, Nvidia is introducing the first RTX 40 cards out next monthBut this has been postponed internally, according to recent reports. It is currently expected that the cards will appear at the end of the third quarter or the beginning of the fourth quarter. Technology site VideoCardz writes† Nvidia will first come with the RTX 4090 and later release lower rated video cards.
