Before the presentation of RTX 4000: AMD through RDNA 3

While the coverage is full of the Geforce RTX 4000, very little has been heard from AMD. The rumor mill also sees nothing in the Radeon RX 7000 that needs to be mentioned in the Ada/Lovelace speculation. But AMD now speaks for itself:

“Looking ahead, we continue to drive more efficient gaming with the AMD RDNA 3 architecture. As the first AMD graphics architecture to take advantage of the 5nm process and our chiplet packaging technology, AMD RDNA 3 is the best way to deliver an estimated performance of more than 50 percent per watt compared to AMD RDNA-2 architecture, giving gamers truly superior gaming performance in cool, quiet, power-conscious designs.

Contributing to this power-conscious design, AMD RDNA 3 refines AMD RDNA adaptive power management technology to set workload-specific operating points and ensure each GPU component consumes only the power it needs for performance. optimum. The new architecture also features a new generation of AMD Infinity Cache; one that aims to provide even denser caches with lower power consumption to reduce graphics memory power requirements, helping to establish AMD RDNA and Radeon graphics as true leaders in terms of efficiency.

We’re excited about the improvements we’re making with AMD RDNA 3 and its predecessors, and believe we can further leverage our advanced architectures and process technologies to deliver unmatched performance per watt across the stack as we continue our momentum. for a better game.

AMD shifts the focus here to efficiency. that’s okay with statements from a while agowhere higher power consumption was also promised for the Radeon RX 7000. At the time they said:

“The demand for gaming and computing power is only increasing at a faster rate, if at all, and at the same time the underlying process technology is slowing down quite dramatically, and the rate of improvement. , energy consumption will continue to increase. We have a multi-year development plan with very significant efficiency improvements to push this curve forward, but the trend is there.”

[…]

“Performance is everything, but while our designs are more energy efficient, that doesn’t mean you can’t push performance even higher if the competition is doing the same. It’s just that they need to set it much higher than us.”

Many interpreted this as an indication that despite 5nm production, you are in the same boat as Nvidia. From the first rumours, it could be assumed that AMD wanted to counter the problem with a more moderate increase in shaders. However, technical information on the Navi 30 fell silent after hinting that Nvidia would exhaust resources. The original approach may have introduced a performance imbalance. With a maximum configurable TDP of 660 watts for the Geforce RTX 4090, Nvidia is said to stay just under 675 watts with a new connector and the PEG. According to rumours, there are just over 16,000 FP32 shaders; at AMD, the last mentioned state was 12,288 shaders for Navi 31.
