AMD Navi 20 GPU to crush RTX 2080 – 20% more powerful for $430
Back in December last year, new AMD Navi GPUs popped up on the web, namely Radeon RX 3060, RX 3070 and RX 3080. We have two more GPUs this time, and according to AdoredTV, these are Anniversary Edition chips, which are set to launch later this year.
Keep in mind that there is nothing confirmed about the next-gen AMD cards yet. And, this far back, a lot of times the companies themselves have not decided on the final names or product specs. So you should better think of this as more or less what they are aiming for.
Special Edition Navi 20 GPU offers nearly 2x Price/Perf of RTX 2080
The leak mentions two new 7nm Navi GPUs. First, we have the Special Edition Navi 10. It comes with 56 compute units, offering a 15% performance boost over the RX 3080, which itself is 10-15% more powerful than Vega 64. The Special Edition Navi 10 is set to feature a TDP of 180 watts, with a price tag of $330.
Then comes the Special Edition Navi 20, and this is where things get interesting. Supposedly, this 225W GPU with 64 compute units is 20% more powerful than the Nvidia RTX 2080, yet it comes in at just $430. Basically, it is nearly double the price to performance of the 2080.
| Graphics Card | Chip | Compute Units | Memory | Performance | TDP | Price |
| Special Edition | Navi 20 | 64 | ? GDDR6 | RTX 2080 + 20% | 225W | $430 |
| Special Edition | Navi 10 | 56 | ? GDDR6 | RX 3080 + 15% | 180W | $330 |
| RTX 3080 | Navi 10 | 48 | 8GB GDDR6 | Vega 64 + 10-15% | 150W | $250 |
| RTX 3070 | Navi 12 | 40 | 8GB GDDR6 | Vega 56 | 120W | $200 |
| RTX 3060 | Navi 12 | 32 | 4GB GDDR6 | RX 580 | 75W | $130 |
Now, while that flat-out sounds too good to be true – which it very well may be – there is this related piece of news that makes it at least slightly more believable.
The story we’re referring to is a leaked image posted on the Baidu forums of which they claim as a Navi PCB. This definitely seems to be something new from AMD featuring traces for either 8GB or 16GB of GDDR6 memory.
Given that the Navi GPU comes with a suggested 256-bit bus and the effective frequency of 12 or 14GHz, it would bring it to 384 or 448 GB/s of bandwidth. That’s definitely not bad since AMD’s GCN architecture needs all the memory bandwidth that it can get.
This is also important because while GDDR6 is more expensive than GDDR5, it is significantly less expensive than HBM2.
That coupled with the 7nm process on the potential for a chiplet-type design, and something that isn’t just a repurposed Instinct card, AMD could lower their cost and subsequent prices by quite a bit. Whether they can get at that low a price is tough to say but we shall see.
