Radeon RX 8000 “RDNA 4” GPUs To Utilize 18 Gbps GDDR6 Memory for entire lineup

[John Elden Ring]

Now based on the latest rumor from @Kepler_L2, it looks like the AMD Radeon RX 8000 "RDNA 4" GPUs will be utilizing GDDR6 memory and no special or faster variant. They will stick with the just 18.00 Gbps speeds which are slightly lower than the current fastest models such as the 7900 XTX or the 7800 XT. The Radeon RX 7900 GRE, RX 7700 XT, RX 7600 XT & the RX 7600 feature 18 Gbps dies. The current lineup features the following:

• Radeon RX 7900 XTX: 384-bit / 20 Gbps / 960 GB/s
• Radeon RX 7900 XT: 320-bit / 20 Gbps / 800 GB/s
• Radeon RX 7900 GRE: 256-bit / 18 Gbps / 576 GB/s
• Radeon RX 7800 XT: 256-bit / 19.5 Gbps / 624 GB/s
• Radeon RX 7700 XT: 192-bit / 18 Gbps / 432 GB/s
• Radeon RX 7600 XT: 128-bit / 18 Gbps / 288 GB/s
• Radeon RX 7600: 128-bit / 18 Gbps / 288 GB/s

Considering that, we can expect similar bus interfaces which should give us the following memory configurations across the RDNA 4 GPU SKUs:

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

Maybe GTA6 in 2026 will justify buying a new GPU but so far I don't see a single game that makes me want to buy a new GPU.

We have come a long way from games like Half-Life 2 enticing people to buy new GPUs. Now the best thing PC has going on is a path traced patch for an extremely disappointing game from 2020.

Pathetic

Infinity Cache mixes things up with VRAM bandwidth. We don't know how much of it is in the chip nor how high it clocks, and that's making a world of difference.
One thing the 18Gbps spec tells us is once again another pointer that RDNA4 is going to be cost-focused.

If AMD sells a $500 card with RTX 4070 Ti raster+raytracing performance and 16GB VRAM in Q3 2024, they have a winner in their hands.

Nailed it. 11/10 would comment on again.

Needs to be better than that considering Blackwell will be announced as well.
