AMD ‘Big Navi 10, 21, 22 & 23’ Next-Gen GPUs Leaked Ready To Rival NVIDIA Ampere (RTX 3000/3080Ti) GPUs

New update revealed that AMD Big Navi next-gen GPUs will come in 4 variants Navi 10, Navi 12, Navi 22 and Navi 23.

Rogame, a well known hardware leaker has exclusively detailed several Navi GPU SKUs which will be powering all the way from Radeon RX to Radeon Pro series graphics cards on his own website.

Of course, we’ll have the next-generation RDNA 2 based Navi lineup and also existing RDNA 1 based parts which will be offered as a refresh to the existing Radeon RX 5000 series cards and will come in four different variants: Navi 21 XTX, Navi 21 XT, Navi 21 XL and Navi 21 XLE.

Also note that Navi 2X, the primary focus is on the Navi 21 chip which is also referred to as the ‘Big Navi’ GPU. The Navi 21 GPU is expected to power AMD’s enthusiast and flagship offerings that would tackle existing flagships from NVIDIA such as the GeForce RTX 2080 Ti and the GeForce RTX 2080 SUPER while also challenging NVIDIA’s next-generation GeForce lineup based on the Ampere GPU architecture.

The report further contends that AMD intends to produce more wallet-friendly new GPUs based on Navi 10 – as used in existing cards – alongside the aforementioned Navi 21 big guns, as previous speculation has hinted.

These more affordable graphics cards will be the Navi 10 XT+ and XTE+, GPUs which will act as replacements for the existing RX 5700 XT and 5600 XT respectively. There will also be a Navi 10 XM+ which will be the successor to the RX 5600M in laptops.

All the lineups that we aforementioned, we heard that only the flagship models of AMD’s GPUs with RDNA 2 will feature ray tracing support, and the new lower-end options won’t support it (much as Nvidia has hardware level support for ray tracing on RTX cards, but not on cheaper GTX models).

The RDNA 2 family is also touted to disrupt the 4K gaming segment similar to how Ryzen disrupted the entire CPU landscape.

Rogame also reckons there will be two new Radeon Pro Navi 21 graphics cards arriving, following on from the Radeon Pro W5700 and W5700X, and some Navi 21 variants specifically made for Apple and iMac (or iMac Pro) plus Mac Pro refreshes.

AMD also revealed that its RDNA 2 GPUs will deliver a similar performance jump over the first-gen RDNA GPUs like Zen 2 delivered over Zen 1.

The first RDNA GPUs delivered a massive 50% increase in performance per watt over GCN architecture and RDNA 2 GPUs are expected to do the same over RDNA 1, delivering another 50% increase in performance per watt.

According to the roadmap shared by AMD, the RDNA 2 GPUs would feature three key features that will be part of the new GPU architecture. First and foremost is the performance per watt increase which is due to a number of reasons. AMD will be shifting from TSMC’s 7nm process to the more advanced 7nm process node. The new process node itself increases transistor efficiency on the new GPUs while decreasing its overall size, allowing AMD to cram more performance in a much smaller package.

The key changes that have led to a 50% increase in performance per watt include a redesigned micro-architecture with improved performance-per-clock (IPC), a logic enhancement that helps reduce design complexity and switching power and physical optimizations such as increased clock speeds.

Words on the street revealed that both AMD and NVIDIA is dropping their next-gen flagships GPUs this September. But hey the main question here, as ever, will be not just exactly what performance they will offer compared to Nvidia’s cards, but at what price? AMD is good at price cutting which at the end of the day they’ll sell of than expected. Imagine getting a card $400 and it outperform or gives what a $1000 card will.

The other complication for AMD is that Nvidia’s next-gen Ampere graphics cards (we address as RTX 3000 models) although we don’t know that yet. Which will be a very big challenge for the RDNA 2 family but you can’t say for now, we’ll see how it goes once it launches on September as speculated.

AMD or Nvidia can’t be sure how the launch timeframe will pan out, but the main point is that both new graphics card ranges will theoretically be launching close together – so AMD won’t be competing against the GeForce RTX 2080 Ti at the top-end, but the Ampere (presumably RTX 3080 Ti) is going to be another superior to battle with.
