Gainward confirms specifications for Geforce RTX 3080 and RTX 3090

There are only a few days left of Nvidia’s countdown to what is likely to be the unveiling of the Geforce RTX 3000 series, with the graphics architecture “Ampere” under the shell. The company’s reference models of the graphics cards have appeared close together with specifications, but when it comes to models from partner manufacturers, the image material has been leaner.

This summer’s Asus-signed ROG Strix card will be accompanied by rendered images from Zotac and Gainward, where both show the flagship model Geforce RTX 3090. Gainward’s series has the stamp “Phoenix Golden Sample” and is also extended with an RTX 3080 variant, two cards as the manufacturer also takes care to reveal the specifications for – details that the site Videocardz has put its hands on.

Specifications Gainward Geforce RTX 3090 and RTX 3080:

According to many previous rumors, Gainward believes that the pork Geforce RTX 3090 steps up to 24 GB of GDDR6 memory and as many as 5,248 CUDA cores based on Ampere and manufacturing of 7 nanometers. However, the third-party manufacturer is holding back somewhat when it comes to the memory speed of 19.5 Gbps, set against the alleged specifications of 21 Gbps with the fresh GDDR6X memory type. With a bus width of 384 bits, it still results in bandwidth of a solid 936 GB / s.

The Geforce RTX 3080 also twists the memory bandwidth set against the RTX 2000 series and lands at 760 GB / s, through 10 GB of GDDR6X memory at 19 Gbps over a 320-bit wide bus. The number of CUDA cores matches the RTX 2080 Ti at 4,352, but what it looks like in terms of the number of RT and Tensor cores is shrouded in obscurity for both the RTX 3080 and its big brother. However, the product pages emphasize that these are now refined and of the second and third generation, respectively.

Common to the two cards is also support for the PCI Express 4.0 protocol and the implementation of image connections according to HDMI 2.1 and Displayport 1.4a. The Phoenix series Geforce RTX 3090 and RTX 3080 are also equipped with similar cooling solutions equipped with three axial fans, which probably enable the turbo frequencies to stay north of 1,700 MHz to specification.

The cards appear to be relatively power-hungry stories, where the TBP values ​​(Total Board Power) are specified at 320 and 350 watts for Geforce RTX 3080 and RTX 3090 in Gainward version. However, the third-party manufacturer sticks to power supply via dual 8-pin PCI Express connections instead of Nvidia’s 12-pin variant. So does Zotac, which, however, equips for a higher power output through up to three 8-pin connectors.

Wccftech has gathered a huge image gallery here, with the conclusion that Zotac has at least eight graphics card models ready for launch in the near future. The most porky refers to Geforce RTX 3090 and RTX 3080, where three fans are the key word for the cooling solutions, which come with different degrees of RGB lighting. RTX 3070 cards are also visible, which step down to two fans.

The specifications for the top models in the Geforce Ampere family can be assumed to be very close to Gainward’s card, where the differences are in image connections, coolers and frequencies. Price levels may also differ, but it remains to be seen what the reference level will be. At the time of writing, the bids are between SEK 15,400 and 19,000 for RTX 3090, but the results will most likely be presented at 18:00 on September 1, when Nvidia holds the next Geforce event.
