Here is all the information you need about the AMD Radeon RX 7800 XT graphics card, which is based on the RDNA 3 “Navi 31” GPU and will be an increased gaming solution. It will introduce performance levels never previously seen in the PC gaming industry.

AMD Radeon RX 7800 XT RDNA 3 Graphics Card: The Next-Gen Navi 31 Flagship Infused with Chiplet Architecture

The AMD Radeon RX 6000 RDNA 2 graphics cards show that the red team can provide performance that is on par with or even better than the rival GeForce RTX series. Each section experienced a significant performance boost, but the Navi 21 series stood out as having performance that rivaled the powerful RTX 3090 Ti from NVIDIA.

AMD not only gave its gaming consumers a brand-new GPU package but also a package that was enhanced by a wide range of architectural and software breakthroughs like Infinity Cache technology, FSR, and Smart Access Memory. Ray Tracing, DirectX 12 Ultimate, and visual upscalers technologies are just a few of the capabilities that work together to give Radeon gamers a fluid and efficient gameplay experience.

With the forthcoming flagship, we should anticipate similar results, although it’s crucial to keep in mind that GPUs are growing more expensive and power-hungry. As we develop better products, this tendency may persist in the future, but there will always be a price for buyers to pay. Beginning with what we now know, we should examine the brand-new RDNA 3 GPU core, which is predicted to make its launch in the array of Radeon RX 7000 series graphics cards.

AMD Navi 31 ‘Plum Bonito’ GPU – The Next-Gen RDNA 3 Powerhouse-

The Navi 31 GPU is the top-tier RDNA 3 SKU in the series. The 2022 flagship is rumored to be built on the Navi 31 GPU, even though an even faster processor is in the works and is anticipated to launch next year. The flagship Navi 31 GPU of the AMD RDNA 3 GPUs, which will be a member of the ‘GFX11’ family, is internally known as ‘Plum Bonito,’ as opposed to the Navi 21 GPU of the RDNA 2 flagship, which was internally known as ‘Sienna Cichlid. The RDNA 3 range is anticipated to follow AMD’s practice of giving its internal codenames for the gaming GPU portfolio fishy names.

AMD revealed that their RDNA 3 GPUs, which feature a significant performance boost, will be released later this year. David Wang, Senior Vice President of Engineering, Radeon Technologies Group, stated that the new GPUs for the Radeon RX 7000 series will provide a 50% increase in performance per watt over the RDNA 2 GPUs now in use. The following are some of the significant RDNA 3 GPU characteristics that AMD will emphasize-

  • 5nm Process Node
  • Advanced Chiplet Packaging
  • Rearchitected Compute Unit
  • Optimized Graphics Pipeline
  • Next-Gen AMD Infinity Cache
  • >50% Perf/Watt vs. RDNA 2

The RDNA 3 GPUs from AMD, which will power the following generation of Radeon RX graphics cards, were recognized for a handful of their significant capabilities in the information the firm shared. The RDNA 3 GPU will have a 5nm process node as its foundation and use cutting-edge chiplet packaging that increases performance per watt. In addition, the GPU will house several novel technologies, including the next-generation Infinity Cache, a completely new and redesigned Compute Unit, and an enhanced graphics pipeline.

AMD will redesign the compute units in RDNA 3 to provide improved graphics card capabilities. Although it isn’t specified, if we had to guess, we would say that it is undoubtedly referring to performance and several cutting-edge functionalities on the RDNA 3 GPU core for Radeon RX 7000 graphics cards.

AMD’s Radeon RX 6000 series graphics cards with RDNA 2 GPUs were the first to support raytracing on the red side. They are behind NVIDIA by a generation, who released their first raytracing GPUs on the Turing graphics architecture two years earlier and improved it further to give higher performance in the Ampere second generation. We can anticipate AMD to provide a similar performance improvement or surpass Ampere’s raytracing capabilities, with the RDNA 3 GPU-powered Radeon RX 7000 scheduled for release later this year. The test will be whether the Ada Lovelace-powered GeForce RTX 40 series can compete with NVIDIA’s 3rd Gen RT (Raytracing) cores.

Along with raytracing, AMD will upgrade the RDNA 3 GPUs with an Optimized Graphics Pipeline to enable even faster clock speeds than RDNA 2 GPUs. With a better 5nm technology node, AMD should be able to exceed the 3 GHz frequency limit since the AMD Radeon RX 6000 cards already operate at speeds near that. This is crucial for AMD because their rival isn’t holding back either; RTX 40 series reports reportedly suggest up to 3 GHz clock speeds using the more effective 4N technology.

In contrast, AMD will also use the RDNA 3 graphics architecture’s powerful GPU capabilities to create a broader software ecosystem, including support for AV1 and brand-new WMMA Instructions that enable AI-Learning with the aid of specific hardware blocks. With RDNA 3 GPUs, the company is anticipated to introduce its next-generation FSR 3.0 technology, which will take on NVIDIA’s AI-Assisted DLSS feature set.

The GPUs would also be among the first to use the product PCIe Gen 5.0 interface, enabling transfer speeds of up to 128 GB/s. This will be a crucial development for the Smart Access Memory feature and pave the way for SAS. According to Microsoft’s Direct Storage API, a brand-new part was created to provide quicker page load time and improved texture streaming in games. The new graphics cards will also have display features, including DP 2.0 and HDMI 2.1.

AMD Radeon RX 7800 XT Graphics Card Features-

The Radeon RX 7800 XT graphics card and other next-generation enthusiast cards would be powered by the AMD Navi 31 GPU, the top-tier RDNA 3 processor. We’ve heard that AMD would replace its next-generation RDNA 3 GPUs’ compute units with workgroup processors. Dual CU will be housed in each WGP, but there will be four SIMD32 clusters per CU instead of two on each CU in RDNA 2. According to rumors, AMD has the choice of the 6nm die from TSMC or Samsung. Similar to the RX 6800 XT, the Radeon RX 7800 XT will be a somewhat scaled-down SKU.

  • AMD Radeon RX 7800 XT: 308mm2 GPU Die @5nm, 10752 Cores, 320-bit Bus, 80-160 MB Infinity Cache
  • AMD Radeon RX 6800 XT: 520mm2 GPU Die, 256-bit Bus, 4608 Cores, 128 MB Infinity Cache

The most recent information indicates that the reduced AMD Navi 31 GPU with RDNA 3 architecture is anticipated to provide a single GCD with 42 GPS. This will distribute 10,752 stream processors in total. This represents a 2.3x increase in cores over the Navi 21 XT GPU’s 4608 SPs found in the RX 6800 XT. According to reports, the Navi 31 GCD, often known as the GPU, would be packaged on TSMC’s 5nm production node and measure 308mm2.

The Navi 31 XT GPU will also have 5 MCDs, each of which will have a 16 MB Infinite series Cache and could also be 64-bit (32-bit x 2) memory controllers, giving the device a 320-bit bus interface. Given that the RX 6800 XT already has 16 GB of memory, we may anticipate the card to have 20 GB of GDDR6 memory (Samsung). With over 16 GB capacities on the top-tier cards, AMD would like to keep its clear advantage in memory storage over the RTX 3080.

There is a 3D-Stacked solution in development that would double the Infinity Cache with 32 MB (16 MB 0-hi + 16 MB 1-hi) capacity for a total of 160 MB of cache, albeit this equates to 80 MB of Infinity Cache, which is less than the 128 MB featured on the current Navi 21 GPUs. With a 25% improvement over the contemporary Navi 21 design, Navi 31 is the first GPU to feature chiplet and 3D stacked designs. These chiplets, also known as MCDs, will be produced on TSMC’s 6nm production node and have a 37.5mm2 surface area each.

As a result, there will be a higher power draw, and AMD appears to have confirmed this. However, their array of next-generation graphics cards will continue to be more energy-efficient than what NVIDIA has to offer, despite having higher power usage. For a >2x performance increase, the AMD Radeon RX 6950 XT already has a TBP of 335W. The revised triple-fan cooling design, which is a little bit taller than the one presently being used, is likely to stay on the cards, along with its dual 8-pin connector input for power.

AMD Radeon RX 7800 XT Graphics Card Performance-

Since the release is still far off, we can only utilize theoretical performance estimates for these massive GPUs. Still, based on what we understand from anticipated theoretical compute estimates, the performance is likely to increase by more than 2.3 times compared to current cards. It’s a significant leap-

  • 75,00 TFLOPs (FP32) for AMD Radeon RX 7900 XT (Assuming 3.0 GHz clock)
  • 64.50 TFLOPs (FP32) on the AMD Radeon RX 7800 XT (Assuming a 3.0 GHz clock)
  • 23.80 TFLOPs (FP32) for AMD Radeon RX 6950 XT (2324 MHz Boost Clock)
  • 23.04 TFLOPs (FP32) for AMD Radeon RX 6900 XT (2250 MHz Boost clock)
  • 20.74 TFLOPs (FP32) for AMD Radeon RX 6800 XT (2250 MHz Boost clock)
  • 16.17 TFLOPs (FP32) for AMD Radeon RX 6800 (2105 MHz Boost clock)

You can get up to 65 TFLOPs of computing performance based on a 3.0 GHz theoretical clock speed, and there are reports of even greater boost speeds. Even though computational performance does not always reflect overall game performance, it will be a significant improvement for gaming PCs and a 5.3x improvement over the current fastest console, the Xbox Series X.

Without even considering the brand-new architectural elements, which are anticipated to improve performance in their respective departments significantly, there will be an increase in calculating the performance of more than 2x for each graphics card compared to its predecessor. FLOPs don’t always reflect visuals or gaming performance but offer a standard to measure differences. If AMD wants to compete with NVIDIA’s Geforce RTX 40 series, they will undoubtedly need to improve performance by 3.25x over the RX 6800 XT.

AMD Radeon RX 7800 XT Graphics Card Price & Availability-

The high-end models of the AMD Radeon RX 7000 series graphics cards, such as the Navi 31, Navi 32, and Navi 33 GPUs, will be the emphasis first. The Navi 33 GPU-based graphics card was rumored to be the first, with Navi 31 and Navi 32 following. However, the leaker had noted that those plans were no longer relevant. Although we don’t know which GPUs will be available first, AMD will probably introduce its Navi 33 and Navi 31 models first. The launch of the cards is anticipated for either late October or mid-November, which corresponds to a Q4 2022 debut.

The AMD Ryzen 7000 “Zen 4” desktop CPUs, which will also be available in the fall of 2022, will launch around the same time. And that’s not all: Intel is also anticipating a Q4 2022 launch for its 13th Gen Raptor Lake CPU family. NVIDIA is likewise aiming for a Q4 2022 debut. It will be a heated Q4 this time because four significant desktop PC releases will be later this fall. Still, users will be in for a treat because there will be a wide variety of gear available for their next-generation gaming PC designs.
