Alleged image of AMD Big Navi The “Navi 21” graphics card that will power the next generation of the Radeon RX 6900 XT graphics card has been leaked Coreteks. Supported by RDNA2 architecture, the AMD Big Navi GPU appears to be bulky when compared to AMD’s previous flagship GPU offerings.

AMD Radeon RX 6900 XT’d “Big Navi” RDNA 2 GPU claimed to be imaging, mega block and GDDR6 memory

Coreteks removed all the mentions and labels on the GPU template to hide its sources, but mentioned that the GPU we’re looking for is actually the Big Navi “Navi 21” GPU that will be shown on the flagship Radeon RX 6900 XT graphics card. The GPU appears to be fairly large and is said to measure around 536mm2 although these are only rough calculations and the final template size may be higher or lower. The template size also appears to be close to Previous rumors Which indicated the die size of 505 mm2 for the main GPU.

AMD Ryzen 9 5900X 12 Core and 24 Thread Zen 3 CPU benchmark leaked – up to 15% faster in multi-threaded tests and 25% faster in single-threaded tests vs Ryzen 9 3900X

One of the main aspects of this leak is that it shows the alleged Navi 21 GPU in a fairly standard template package. This could refer to a memory configuration based on GDDR6 instead of HBM2 (e) as several leaks have indicated in the past. There is still some speculation that the Navi 21 XT and XL blocks will feature standard GDDR6 configurations while the Navi 21 XTX die HBM2 (e) will use the memory subsystem but this is an area of ​​speculation and has yet to be confirmed.

The Recent leaks along with Leaked PCB photos The card indicates that it will contain 16 GB of GDDR6 memory via a 256-bit bus interface. Note that 16GB VRAM is also possible with a 512-bit interface so AMD is also open to this option when releasing final specifications. We only have a few weeks left until the lineup is revealed, but AMD and the tech press are giving us quite a few teasers and leaks in the meantime.

AMD Radeon RX 6900 Series with 3-Slot Cooling Solution:

As for the designs themselves, the Pioneering Radeon RX 6000 cooling design It looks amazing with the red and black design. The card features a 3-axis fan setup on the shroud and has a large aluminum heatsink running underneath. The card has an LED-lit Radeon logo on the side and there is a large hole on the side for fans to vent 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 outlets and will include USB Type-C (VirtualLink) display ports, 1 HDMI and 2 DisplayPort connectors.

The card also has a nice back panel along with a retaining bracket to hold the cooler in place. The Radeon RX “Big Navi” GPU appears to come in the standard two-slot reference design and is the same as the NVIDIA RTX 3080 flagship but not as big as the 3-slot GeForce RTX 3090.

Here’s everything we know about RDNA 2-based Radeon RX Navi 6000 GPUs

The Radeon RX Navi 2x graphics card based on AMD RDNA 2 The family has also been touted to disable the 4K gaming sector similar to the way Ryzen completely disabled the CPU scene. This is a very bold claim from AMD itself, but leaks and rumors suggest this may be the case for AMD’s next-generation Radeon RX graphics cards.

AMD revealed that its RDNA 2 GPUs will deliver a similar performance jump over the first generation RDNA GPUs as the Zen 2 delivered over the Zen 1. The first RDNA GPUs provided a massive 50% increase in performance per watt over the GCN architecture. And RDNA 2 GPUs are expected to do the same on RDNA 1, providing a further 50% increase in performance per watt.

According to the roadmap that AMD is sharing, RDNA 2 GPUs will have three main 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 switch from TSMC’s 7nm process to more advanced 7nm process node. The new process node itself increases transistor efficiency in new GPUs while reducing its overall size, allowing AMD to achieve more performance in a much smaller package.

The major changes that led to a 50% increase in performance per watt include redesigned micro architecture with improved performance per hour (IPC), a logic optimization that helps reduce design complexity and power conversion, and physical improvements such as increased clock speeds.

AMD also announced that RDNA 2 GPUs will feature hardware-accelerated VRS (variable rate shading) and ray tracing. AMD follows suit with NVIDIA here who have already applied the aforementioned technologies to Turing GPU-based GeForce RTX graphics cards. With the near release of new Microsoft and Sony consoles, AMD will work to bring these features to its optimization framework for developers for integration with next-generation games.

AMD also recently offered to run 2 RDNA GPUs Microsoft DXR 1.1 (DirectX 12 API Ultimate) Demo internally which uses hardware accelerated ray tracing. AMD’s approach to ray tracing is to offer streamlined development and fast adoption and this is certainly possible with consoles as the vast majority of game developers focus their efforts on them.

AMD CEO, Dr. Lisa Su, has a Already mentioned We can expect to launch a high-end Radeon RX family based on the RDNA 2 GPU and 7nm RDNA refresh family for launch this year. The same was mentioned during the presentation in which it was mentioned that the “Navi 2x” lineup will be graded from top to bottom and as the name suggests, will provide twice the performance efficiency compared to the first generation RX graphics cards.

AMD CFO Devinder Kumar also shed some light on Radeon RX products based on the RDNA 2 GPU for the PC platform, indicating that computers will be the first to sample the new architecture in the form of a Big Navi (Halo) graphics card followed by mainstream GPUs.

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

  • Improved 7nm process node
  • Enthusiast-class desktop graphics card options
  • Support for ray tracing at the hardware level
  • Combination of GDDR6 graphics cards
  • More power efficient than 1st generation Navi GPUs

One of the main features is on Big Navi Radeon RX GPU is that it will disrupt the 4K gaming sector, Similar to the way Ryzen completely disabled the CPU sector. Those are some bold claims by AMD, but if they are Specification rumored Anything he goes through, the claims may not be far-fetched.

Once again, AMD confirmed in its presentation special the enthusiast-class performance of RDNA 2-based Radeon RX ‘Navi 2X’ GPUs, so that’s something to keep in mind. However, the competition from the other side will not only close your eyes as AMD releases high-performance graphics cards.

AMD will The curtain will be officially unveiled Radeon RX 6000 series graphics cards on October 28th. The second half of 2020 will definitely be fun times for all hardware enthusiasts and casual PC gamers looking to upgrade their PCs with the best hardware.
