AMD RDNA 5 To Be A Completely New GPU Architecture From The Ground Up, RDNA 4 Mostly Fixes RDNA 3 Issues & Improves Ray Tracing

AMD's next-generation RDNA 5 GPUs are being built from the ground up and are meant to be the “Zen” moment for the Radeon division.

AMD Radeon may have to wait until RDNA 5 to get its “Zen” moment as RDNA 4 GPUs mostly adapt with better ray tracing.

The new rumor comes from Chappell forum member, wjm47196who is known for his cryptic messages on the site but has been proven right when it comes to some of his past leaks such as Radeon RX 6000 Refresh And NVIDIA RTX 30 series cards. It's been a while since these GPU series were launched so now the forum member is back to post about the next generation series from AMD.

Laker says that AMD's plans with the RDNA 3 GPU lineup did not go as expected. The problems with RDNA 3 arose from the final silicon not meeting internal performance estimates and it was clear that the performance increase was not as necessary as it was exaggerated. NVIDIA “Ada” GPUs, on the other hand, destroyed AMD RDNA 3 chips in performance data across all categories. Additionally, AMD had to cut back on what their initial designs were going to include. Infinity cache up to 192 MB only 96 MB due to cost and power constraints.

Looking ahead, AMD's RDNA 4 GPUs are going to be mostly an architectural adaptation of RDNA 3. The lineup is said to be comparable to Radeon RX 7900 XT GPUs and as we know, there are going to be two SKUs, Navi 48 and Navi 44, both of which will be targeted at mainstream and entry-level users similar to the first-generation RDNA GPUs (Radeon RX 5000 series). One area where we can see some big improvements is in ray tracing performance The rumors we've heard so far. Especially since a similar IP block will be leveraged for the future. Sony PS5 Pro Console.

There is also AMD RDNA 3+ Among the tasks that will primarily power the iGPU side of things on next-gen Ryzen APUs are e.g Strix Point and Strix Hello. Also, we are unaware if RDNA 3+ will be limited to iGPUs or if we will see a discrete offering based on the architecture. Recent rumors also state that AMD does not plan to introduce any new Radeon RX 8000 GPUs this year, but NVIDIA is expected to launch its flagship Blackwell RTX 5090 and RTX 5080 GPUs later this year.

So next, we have the AMD RDNA 5 GPUs. The next generation of GPUs after RDNA 4 will be built on an entirely new architecture designed from the ground up, and it's also unknown whether AMD will retain the RDNA 5 branding for it or something entirely new. will switch to The promise of a “Zen” moment in the Radeon family has been long awaited and RDNA 5 is expected to be just that.

AMD will conduct a thorough case study and R&D when designing the next-generation architecture. RDNA 5 is also believed to be the primary cause. Why is rDNA 4 being cut so much? So that it can spend more time perfecting the next generation while offering a mainstream series that doesn't require huge development costs. The GPU architecture is also rumored to be used in the next generation. The Medusa APU lineup includes Zen 6 cores..

Additionally, the rumor puts a lot of emphasis on how AMD will fine-tune its AI and ROCm software suite by directly involving Xilinx in this matter. The “Radeon AI” branding is something we may see in future GPUs as the Radeon team focuses more on the “AI PC” segment, certainly when its The main competitor calls “RTX” a premium AI PC platform..

AMD RDNA 5 GPUs are still several years away from launch and it will be in late 2025 or 2026 when we start to get a hint of what AMD is building. Whether this will be the zen moment the Radeon team has been waiting for is something we'll find out in the coming years.
