AMD NVIDIA

The next generation of graphics cards
should arrive next fall, but the first “comparisons” are already there.

If you follow the news of the graphics card at least, you are aware that the next generations signed AMD and NVIDIA should be the occasion of a certain opposition of style.

The next MCM-based Radeons

Indeed, while NVIDIA on its future generation Ada Lovelace – the GeForce RTX 4000 series – seems to have to remain on a so-called monolithic design of its GPU, AMD will clearly change course.

The Radeon RX 7000 series will be based on the RDNA 3 architecture, but it has already been confirmed that for this one, AMD will switch to a so-called MCM design to Multi-Chip Modules. The idea here is to make two – or even more – GPUs work together.


This should make it possible to offer better performance while keeping the design of each GPU less complex. The process is not new and AMD is already using it with some success on its EPYC and Ryzen range CPUs.

The RX 7900 XT ahead of the RTX 4090?

Accustomed to leaks of all kinds, Moore’s Law is Dead today communicates information to be taken with hindsight. We are indeed still far from the release of the cards he mentions in his video.

Still, the calculation made is interesting. Moore’s Law is Dead based on available information to conclude that the Radeon RX 7900 XT could have a total of 15,360 stream processors, which is triple what the RX 6900 XT contains. As far as NVIDIA cards are concerned, we would be at 18,432 CUDA cores on the RTX 4090 compared to 10,496 on the RTX 3090.

For the GeForce, it would be a performance increase of between 66% and 80% compared to the RTX 3090. On the other hand, AMD could count on a tripling of the power between the RX 6900 XT and the RX 7900 XT… what to get ahead of NVIDIA?

On the only field of energy efficiency where AMD is already efficient, the MCM design and the fineness of engraving (combination of TSMC 5 nm and 6 nm processes) should allow it to widen the gap. One thing is certain, we can’t wait to see all this!
