AMD’s Radeon RX 6000 series graphics cards based on the RDNA 2 architecture have been pictured once again. This time, we are looking at both, a triple-fan and a dual-fan cooling solution that are designed for AMD’s next-generation Navi 2X lineup of GPUs for the enthusiast & high-performance gaming segment.
AMD Radeon RX 6000 Series Graphics Cards Pictured – Flagship Radeon RX 6900 Series Gets Triple-Fan & Radeon RX 6800/6700 Series Gets Dual-Fan Cooling
The latest pictures were unveiled by JayzTwoCents who got them through his sources and talked about them in his latest YouTube video. One of the two cooling shrouds was already been made official by AMD yesterday while a second shroud with a dual-fan cooling solution has also been pictured. Interestingly, the dual-fan cooling solution was teased by AMD a while back within its investor presentation.
So coming to the design of the card and which graphics cards would feature these coolers, Jayz states that the triple-fan cooling solution is going to be featured on the Radeon RX 6900 series which would feature the “Big Navi” GPU while the dual-fan cooling solution is going to be part of the Radeon RX 6800 or the Radeon RX 6700 series graphics cards. The Radeon RX 6800 / Radeon 6700 series graphics cards will feature a different Navi 2X GPU (most probably Navi 22) and will target the sub $500 US market range.
AMD Radeon RX 6900 Series With Triple-Slot Cooling Solution:
As for the designs themselves, the Radeon RX 6000 flagship cooling design looks amazing with the red and black design. The card features a triple axial-tech fan setup on the shroud and has a large aluminum heatsink that runs beneath it. The card has a LED-lit Radeon logo on the side and there is a large cut out on the side for the fans to vent out hot air. This design is very reminiscent of the NVIDIA GeForce RTX 20 series Founders Edition cooler. The card will feature dual 8-pin power and display ports would include a USB Type-C (VirtualLink), 1 HDMI, and 2 DisplayPort connectors.
The card also features a fancy backplate along with a retention bracket to hold the cooler in place. The Radeon RX “Big Navi” GPU looks like it will come in the standard 2-slot reference design which is the same as NVIDIA’s flagship RTX 3080 but not as huge as the triple-slot GeForce RTX 3090.
AMD Radeon RX 6800/6700 Series With Dual-Slot Cooling Solution:
Moving over to the second variant, the dual-slot card features a design similar to the triple-slot offering but with a slightly compact form factor. This shroud is said to be designed for the AMD Radeon RX 6800 or Radeon RX 6700 series cards. The card features a dual axial-tech fan design and has the large “R” logo in the middle and on the fans too which represent the Radeon brand.
The card also features the LED-lit Radeon logo on the sides and has the large cut out to vent out the heat from the aluminum heatsink. There are two 8-pin power connectors on the card but we may also see 8+6 or configurations for the more power optimized variants. The card also comes with a dual-slot form factor and should feature a similar I/O as the Big Navi graphics card.
It is expected that this cooler should house the Navi 22 GPU which is slightly smaller but still larger compared to AMD’s Navi 10 (RDNA 1) GPU for the Radeon RX 5700 series graphics cards. There’s a large possibility that the PCB that leaked out a few days ago belonged to a Navi 22 based graphics card.
AMD Radeon RX 6000 Series RDNA 2 GPUs To Feature AV1 Decoding
In additional news, Videocardz has found out that AMD has added support for VCN 3.0 AV1 register to the latest Linux patches. NVIDIA’s soon to be launched GeForce RTX 30 series are confirmed to feature fully hardware-accelerated AV1 decoders while Intel’s Xe GPUs also come with AV1 decode support. AV1 offers up to 50% higher bitrate efficiency over H264 & 30% higher efficiency over VP9 and HEVC decoding formats.
Here’s Everything We Know About RDNA 2 Based Radeon RX Navi 6000 Desktop GPUs
The AMD RDNA 2 based Radeon RX Navi 2x graphics card family is also touted to disrupt the 4K gaming segment similar to how Ryzen disrupted the entire CPU landscape. That’s a pretty bold claim from AMD themselves but leaks and rumors are suggesting that this might be the case for AMD’s next-generation Radeon RX graphics cards.
AMD unveiled 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.
AMD has also announced that RDNA 2 GPUs would feature VRS (Variable Rate Shading) and hardware-accelerated ray tracing. AMD is following suit with NVIDIA here who have already implemented the said technologies on its Turing GPU based GeForce RTX graphics cards. With the launch of the new consoles from Microsoft and Sony imminent, AMD is going to work to provide these features with its own optimization framework to developers for integration within next-generation gaming titles.
AMD has also recently showcased its RDNA 2 GPUs running Microsoft’s DXR 1.1 (DirectX 12 API Ultimate) demo internally which utilizes hardware-accelerated ray tracing. AMD’s approach to ray tracing is to offer simplified development and speedy adopting and that is definitely possible through consoles where the mass majority of game developers focus their efforts towards.
AMD’s CEO, Dr. Lisa Su, has already stated that we can expect a new RDNA 2 GPU based Radeon RX high-end family and a 7nm RDNA refresh family to launch this year. The same was stated during the presentation in which it was stated that the “Navi 2x” lineup would scale from top to bottom and as the name suggests, would deliver twice the performance efficiency increase over the first-generation RX graphics cards. AMD’s CFO, Devinder Kumar also shed some light on the RDNA 2 GPU based Radeon RX products for the PC platform, stating that PCs will be first to get a taste of the new architecture in the form of the Big Navi (Halo) graphics card followed by mainstream GPUs.
“There’s a lot of excitement for Navi 2, or what our fans have dubbed as the Big Navi“
“Big Navi is a halo product”
“Enthusiasts love to buy the best, and we are certainly working on giving them the best”.
“RDNA 2 architecture goes through the entire stack“
“it will go from mainstream GPUs all the way up to the enthusiasts and then the architecture also goes into the game console products… as well as our integrated APU products.
“This allows us to leverage the larger ecosystem, accelerate the development of exciting features like ray tracing and more.”

Some of the features to expect from 2nd Generation RDNA Navi GPUs would be:
- Optimized 7nm process node
- Enthusiast-grade desktop graphics card options
- Hardware-Level Ray Tracing Support
- A mix of GDDR6 graphics cards
- More power-efficient than First-Gen Navi GPUs
One of the key features on the Big Navi Radeon RX GPU is that it is going to disrupt the 4K gaming segment, similar to how Ryzen disrupted the entire CPU segment. These are some bold claims by AMD, but if those rumored specifications are anything to go by, then these claims may not be that far fetched.
“With the Radeon 5000-series we are essentially covering 90-something-percent of the total PC gamers today,” says Chandrasekhar. “And so that’s the reason why no 4K right now, it’s because the vast majority of them are at 1440p and 1080p.
“That doesn’t mean a 4K-capable GPU isn’t coming, it is coming, but for here and now we want to focus on the vast majority of gamers.”
“Similar to Ryzen,” he says, “all of us need a thriving Radeon GPU ecosystem. So, are we going after 4K, and going to similarly disrupt 4K? Absolutely, you can count on that. But that’s all I can say right now.”
Once again, AMD in its own presentation emphasized enthusiast-class performance for the RDNA 2 based Radeon RX ‘Navi 2X’ GPUs so that’s something to consider. The competition however from the other side won’t just go eyes closed as AMD launches its high-performance graphics cards. The next-generation NVIDIA based GeForce GPUs are shaping up to be a beast from what we’ve seen so far and will be available first to consumers, starting the 17th of September.
The second half of 2020 would definitely be interesting times for all the hardware enthusiasts and mainstream PC gamers who are looking forward to upgrading their PCs with the best hardware.
