AMD has confirmed its next-gen RDNA 4 GPUs in ROCm which include the Navi 44 “GFX1200” & Navvi 48 “GFX1201” SKUs for Radeon RX 8000.
AMD Navi 44 “GFX1200” & Navi 48 “GFX1201” RDNA 4 GPUs Confirmed In ROCm, Coming To Next-Gen Radeon RX 8000 Graphics Cards
Although the information isn’t surprisingly new, the AMD ROCm Github has confirmed both Navi 44 and Navi 48 GPUs which are based on the RDNA 4 graphics architecture along with their respective graphics IDs. As expected, the AMD Navi 44 is tagged as “GFX1200” while Navi 48 is tagged as the “GFX1201” SKU.
Not much is mentioned within the ROCm GitHub about this upcoming AMD RDNA 4 GPU SKU but as per the latest rumors, the Navi 48 GPU is expected to be the fastest of the two chips and will target the more higher-end product offerings. With that said, Navi 48 isn’t a typical high-end SKU like the Navi 31 (RDNA 3) or Navi 21 (RDNA 2) series as those were reportedly canned in favor of more mainstream chips to target the mass market.
As such, the AMD Navi 48 GPUs are currently expected to land somewhere around Navi 31 performance while being strong perf/$ options for the gaming masses. Currently, the AMD Radeon RX 7900 GRE, the entry-level RDNA 3 SKU, retails for around $549 US since its new pricing update. If AMD manages to offer better performance than the 7900 GRE at a price point of around $400-$500 US, then that could be a killer deal for gamers.
One thing to note is that AMD’s RDNA 4 GPU architecture will be a brand new design so we should also consider the fact that the red team can fine-tune its performance within ray tracing titles and also offer additional goodies such as an AI-infused FSR upscaling technology which rivals NVIDIA’s DLSS even though FSR 3 in its current state is a very good alternative for gamers. AI acceleration can sort some of the shortcomings of FSR and bring enhanced image quality in areas where it currently lacks against DLSS.
Although limited details are available on the RDNA 4 GPUs, we can expect the next-generation lineup to feature support for GDDR7 memory which will initially come in 28/32 Gbps dies & with 16Gb (2 GB VRAM per module). However, AMD could also go the more cost-effective route and simply use faster GDDR6 dies for now. The chips are also rumored to be smaller and monolithic which means that the MCD design will be abandoned a year after its introduction.
