AMD Radeon RX 8000 “RDNA 4” GPUs To Utilize 18 Gbps GDDR6 Memory Across Entire Lineup

AMD may stick to the good old-fashioned 18 Gbps GDDR6 memory solution for its next-generation RDNA 4 “Radeon RX 8000” GPUs, it's alleged. @Kepler_L2.

AMD isn't upgrading the memory spec on its RDNA 4 “Radeon RX 8000” GPUs as rumored, with 18 Gbps GDDR6 for all cards.

While memory manufacturers are talking about their latest solutions for consumer graphics cards such as Samsung's GDDR6W Or really The next-generation GDDR7 standard that will initially ship with 28 Gbps die speed., it looks like AMD is planning to stick with the current GDDR6 memory solution to power its upcoming Radeon RX 8000 graphics cards based on the RDNA 4 GPU architecture. This move may seem a bit strange at first but it makes sense as we will understand in a little while.

The AMD RDNA 4 GPU family, which is expected to power the Radeon RX 8000 line of discrete cards, has seen various developments. The lineup was initially expected to feature high-end GPU SKUs until they were canceled and replaced with two SKUs in the mid-range and low-end segments. We know the two SKUs as Navi 48 and Navi 44. The Navi 48 GPU is reportedly the higher-end SKU of the two while the Navi 44 chip is the entry-level SKU. These are part of GPUs. GFX12 family and they are already listed in patches as GFX1200 and GFX1201 within ROCm..

Now based on the latest rumor from @Kepler_L2 , it looks like the AMD Radeon RX 8000 “RDNA 4” GPUs will be using GDDR6 memory and not a special or faster variant. They will only stick with 18.00 Gbps speeds which are slightly lower than the current fastest models like the 7900 XTX or 7800 XT. Radeon RX 7900 GRE, RX 7700 XT, RX 7600 XT and RX 7600 feature 18 Gbps throughput. Considering this, we can expect a similar bus interface to give us the following memory configurations in the RDNA 4 GPU SKUs:

  • Radeon RX 8000: 256 bit / 18 Gbps / 576 GB per second
  • Radeon RX 8000: 192-bit / 18 Gbps / 432 GB/s
  • Radeon RX 8000: 128 bit / 18 Gbps / 288 GB per second

Now, while this may sound a bit disappointing, it looks like AMD's use of 18 Gbps GDDR6 memory for its RDNA 4 lineup could make these cards a better value in their respective segments. GDDR6 memory has already been in mass production for years and is widely available, unlike newer solutions that may initially have limited supply.

Thus, memory vendors can raise prices, resulting in higher prices for discrete products. Another factor could be power draw, these next generation solutions will consume more power despite being slightly more efficient. Since AMD is targeting the mainstream and low-end segment with its RDNA 4 GPU family, it makes sense to include an 18 Gbps solution.

It has also been reported that all RDNA 4 GPUs will use GDDR6 18 Gbps memory so that includes both desktop and laptop offerings. Bandwidth is still plenty for mainstream solutions and there can be an infinity cache that can eliminate some of the memory bottlenecks that GPUs can face. Early rumors suggest that the Navi 48 GPU will offer performance closer to the Navi 31 chips, while the Navi 44 will sit between the Navi 32 and Navi 33 “RDNA 3) GPUs.”.

All in all, it looks like NVIDIA will once again be the first for a new GDDR solution (GDDR7) later this year when it launches Blackwell for gaming. GeForce RTX 5090 and RTX 5080 But this card. Meanwhile, AMD will try to refocus its market share in the mainstream gaming segment before moving back into the high-end segment as it launched the Polaris (RX 400/500) and Navi 1 (Radeon RX 5000) GPUs. what happened to
