In the leadup to what we hope is a 2020 release, we’ve been hearing bits of news concerning AMD’s next lineup of graphics cards for a while now. While it was originally just a rumor at first, now AMD has confirmed that they are working on both an RDNA 2X and RDNA 3X architecture, everything is starting to tie together.
AMD looks to be set to announce their Big Navi GPU later on this year, although the date is not yet confirmed. There are some rumors that point towards both AMD and Nvidia unveiling their next generation of GPUs around September time which would correspond quite nicely with Computex 2020 which was postponed to that month.
Details Surface Over The Number Of Variants Available
Hardwareleaks.com has recently published a post that shows some of the future variants that could be seen as part of the Big Navi lineup. These mainly detailed units in Navi21, which is set to be the largest of the three RDNA 2 GPU based dies that AMD has planned.
The main talking points of Navi21, as detailed by user Rogame are as follows, up to 80 compute units / 5120 GPU cores, a die size of around 505mm², and 50% better performance per watt. This is still to be confirmed by AMD, but on paper, this looks like AMD has something special planned.
The list of GPU variants is as follows:
| GPU Variant | Device ID | Purpose | GPU Variant is Similar to |
|---|---|---|---|
| Navi 21 XTX | 731F:D0 | Radeon RX (Full Die) | RX 5700 XT (50th Anniversary) |
| Navi 21 XT | 731F:D1 | Radeon RX (Full Die) | RX 5700 XT |
| Navi 21 XL | 731F:D3 | Radeon RX (Cut-Down Die) | RX 5700 |
| Navi 21 XE | 731F:DF | Radeon RX (Cut-Down Die) | RX 5600 XT |
| Navi 21 XTA | 731F:50 | New | Unknown |
| Navi 21 XLA | 731F:51 | New | Unknown |
| Navi 21 Pro XTA | 731F:11 | MAC Radeon PRO | Unknown |
| Navi 21 Pro XLA | 731F:13 | MAC Radeon PRO | Unknown |
| Navi 21 Pro-XT | 731F:10 | MAC Radeon PRO | Unknown |
| Navi 21 Pro-XL | 731F:12 | MAC Radeon PRO | PRO W5700 |
It’s interesting to note that there are no mobile variants on this list as well as the fact that Apple will be using four variants which isn’t too much of a surprise. With so many variants on this list however, it seems that AMD is really trying to make the most of this chip.
What do you think of these variants? Do you think these cards will be able to stand up to Nvidia’s next-generation offerings? Let us know down in the comments section below.
