AMD Radeon RX 6000 “Big Navi” graphics card shown, allegedly with 16 GB of GDDR6 memory

The first picture of our first look at the upcoming Radeon RX 6000 series graphics card from AMD leaked online at Bilibili (Via @ Avery78). The picture shows an early test card with a next generation RDNA 2 GPU, which is also used for the AMD Enthusiast-class graphics card.

According to the leaker, the picture is a test board of one of the many AMD RDNA 2-based graphics cards of the Radeon RX 6000 series that the red team plans to unveil on October 28th. The graphics card is supplied with a standard rectangular board. Since this is an early test board, the final retail version would be very different. With that said, a few details are mentioned. So let’s take a closer look at what the PCB has to offer.

It is mentioned that this particular board contains the Big Navi “RDNA 2” GPU. The SKU is not mentioned, but the “XT” label is on the board. So we are most likely looking at the full GPU chip under the cooler, which unfortunately is not shown. Since the back of the PCB is shown, we can clearly see the PCB markings for the GDDR6 memory. There have been rumors that AMD’s Big Navi GPU might use HBM2e memory, but that doesn’t seem to be the case here.

The card allegedly uses 16 GB of GDDR6 memory, which has a 256-bit bus interface. This is an interesting choice, which means there are a total of 8 GDDR6 chips on the front of the PCB in a 3 + 3 + 2 layout.

This also means that every professional variant of the card can have double-sided storage with up to 32 GB of storage. With that in mind, a 256-bit bus suggested that AMD will either have two 16GB models with very different core configurations or a 16GB and 8GB option in its Radeon RX 6000 series, unless , they plan to cut the bus for 12 GB model or take another bus.

AMD could potentially unveil the Radeon RX 6000 series with Big Navi ‘RDNA 2’ GPU-powered tomorrow

In order to achieve a capacity of 16 GB without the use of double-sided memory, AMD will use the 16 Gbit chips that have been in production since the beginning of 2018, which can achieve speeds of up to 16 Gbit / s. A memory speed of 16 Gbps would give us a bandwidth of 512 GB / s for that particular card. But again, the specifications are not finalized yet as this is just a test board and the final version may have a different board with different memory specifications. Other interesting details on the card are the LEDs that indicate the GPU LED. This is part of the GPU speedometer that has been used on several high-end Radeon RX graphics cards and serves as a load meter that shows the load being placed on the GPU. There are also specific ports for running diagnostics in a test environment.

In terms of cooling, you’ll see an inverted tower heatsink, which is a common feature on test boards from NVIDIA and AMD. The heat sink has a large aluminum finned block with fans on both sides and multiple heat sinks that are connected to the GPU itself.

Here is everything we know about RDNA 2-based Radeon RX Navi 6000 desktop GPUs

The Radeon RX Navi 2x graphics card family based on AMD RDNA 2 is also said to disrupt the 4K gaming segment, similar to how Ryzen disrupted the entire CPU landscape. That’s a pretty bold claim made by AMD itself, but leaks and rumors suggest that this could be the case with AMD’s next-generation Radeon RX graphics cards.

AMD announced that its RDNA 2 GPUs will offer a similar leap in performance over the first generation RDNA GPUs as Zen 2 over Zen 1. The first RDNA GPUs delivered a massive 50% per watt performance increase over the GCN architecture and RDNA 2 GPUs It is expected that this will also be the case with RDNA 1, increasing the performance per watt by an additional 50%.

According to the roadmap shared by AMD, the RDNA 2 GPUs would have three key features that will be part of the new GPU architecture. The first and foremost is to increase the power per watt, which can be attributed to a number of reasons. AMD will move from TSMC’s 7nm process to the more advanced 7nm process node. The new process node itself increases the transistor efficiency of the new GPUs while reducing the overall size, allowing AMD to achieve more performance in a much smaller package.

Key changes that have resulted in a 50% performance per watt increase include a redesigned microarchitecture with improved performance per cycle (IPC), a logic improvement that helps reduce design complexity and switching performance, and physical optimizations such as clock rates .

AMD has also announced that RDNA 2 GPUs will offer Variable Rate Shading (VRS) and hardware accelerated ray tracing. AMD is following with NVIDIA, which has already implemented these technologies on their Turing GPU-based GeForce RTX graphics cards. With the upcoming launch of the new Microsoft and Sony consoles, AMD will be working to provide developers with these capabilities with its own optimization framework for integration into next-generation game titles.

AMD recently unveiled its RDNA 2 GPUs that run Microsoft’s DXR 1.1 (DirectX 12 API Ultimate) demo internally, which uses hardware-accelerated ray tracing. AMD’s approach to ray tracing is to offer simplified development and fast adoption. This is definitely possible through consoles that the majority of game developers focus on.

AMD’s CEO, Dr. Lisa Su, has already announced that we can expect a new RDNA 2 GPU-based Radeon RX high-end family and a 7 nm RDNA refresh family this year. The same was noted during the presentation, which stated that the “Navi 2x” lineup would scale from top to bottom and, as the name suggests, would provide twice the efficiency increase over the first generation RX graphics cards. Devinder Kumar, CFO of AMD, also highlighted the RDNA 2 GPU-based Radeon RX products for the PC platform and said that PCs will be the first to get a taste of the new architecture in the form of the following Big Navi (Halo) graphics card of mainstream GPUs.

“Navi 2 is very exciting, or what our fans have called Big Navi.”

“Big Navi is a Halo Product”

“Enthusiasts love to buy the best and we certainly work to give them the best.”

“The RDNA 2 architecture goes through the entire stack”

“It will range from mainstream GPUs to enthusiasts, and then the architecture will go into game console products … as well as our integrated APU products.

“This allows us to take advantage of the larger ecosystem, accelerate the development of exciting features like ray tracing and more.”

Some of the features to be expected from 2nd generation RDNA Navi GPUs are:

  • Optimized 7 nm process node
  • Desktop graphics card options for the enthusiast
  • Ray tracing support at the hardware level
  • A mix of GDDR6 graphics cards
  • More energy efficient than first generation GPS GPUs

One of the key features of the Big Navi Radeon RX GPU is that it will disrupt the 4K gaming segment, much like Ryzen disrupted the entire CPU segment. These are some bold claims from AMD, but if these rumored specs have anything to watch out for, then those claims may not be that far-fetched.

“With the Radeon 5000 series, we essentially cover 90 percent of all PC gamers today,” says Chandrasekhar. “And that’s why there is no 4K right now because the vast majority of them are at 1440p and 1080p.

“That doesn’t mean a 4K capable GPU isn’t coming, it’s coming, but here and now we want to focus on the vast majority of gamers.”

“Much like Ryzen,” he says, “we all need a thriving Radeon GPU ecosystem. So are we going to 4K and interfering with 4K in a similar way? You can absolutely rely on that. But that’s all I can say now . “

In its own presentation, AMD once again emphasized the performance of the enthusiasts for the RDNA 2-based Radeon RX ‘Navi 2X’ GPUs. However, competition from the other side won’t just close their eyes when AMD launches its high-performance graphics cards. The next-gen NVIDIA-based GeForce GPUs are emerging as a beast from what we’ve seen so far and will be available to consumers for the first time on September 17th.

The second half of 2020 would definitely be an interesting time for all hardware enthusiasts and mainstream PC gamers looking forward to upgrading their PCs with the best hardware.

How fast do you think the AMU Big Navi (RDNA 2) GPU-enabled Radeon RX graphics cards will be?
