While NVIDIA continues to launch in a scaled manner the various chips of its Lovelace architecture for the RTX 40, namely: AD102, AD103, AD104 and very soon AD106. On the AMD side and its RDNA 3 architecture, everything can be summed up for the moment in two chips: Navi 31 for the RX 7900 and Navi 33 for the RX 7700. Which brings us to the following question: Where are AMD’s RX 7800 graphics cards?
One of the biggest disappointments, fueled by rumours, was the clock speed achieved by the RX 7900 in the two versions released, XT and XTX. And it is that the jump from 7 nm to 5 nm for the GCD of the GPU also meant an increase in clock speed, which would be favored by a much smaller chip. Reality? It was not like that and it led to the following conclusion: the rumors on the network had completely lied about the GHz reached by the new generation of AMD graphics cards. The answer to these? Talk about how the situation had delayed the design of the rest of the line.
Where are AMD’s RX 7800 graphics cards?
That the RX 7000 has a design problem reaching high clock speeds became clear when AMD at CES showed off its laptop-only Navi 33 chip, the so-called RX 7700S. However, they do not take advantage of the non-existence for the moment of the mid-range RTX 40 which, honestly in terms of price, is far from it and remains in the range of a premium product.
That is, AMD currently has the perfect situation to attack NVIDIA and steal market share, and yet the products are not coming out and we have no record of them. Which brings us to the conclusion that it is true that the architecture might have a problem with the clock speeds that would have sent both the graphics card version of the Navi 33, the RX 7700, but especially the RX 7800, would have returned to the normal design table before going into pre-production.
Such a problem would not have been something the Radeon Technology Group would have noticed during the presentation, but much earlier, during the validation phase of the chips. So they would release the RX 7900 XT and XTX to hit the record, along with the RX 7700 for laptops, and they would have decided to delay the rest of the chips so they could achieve much higher clock speeds than in the first design. . In any case, we can say that they are late and that’s a shame, because the lack of competition from NVIDIA makes the prices too high in the graphics card market.
But is there any evidence that it is still in development?
We know the RX 7800 GPU hasn’t been cancelled, so rest assured we’ll see it hit the market eventually. The parts that have not varied with the four MCDs that allow to have a 256-bit bus for 16 GB GDDR6 configuration. It is the main chip that has undergone last minute changes and we cannot say with absolute certainty what its configuration is.
The little that is known is that it will be between the 32 Compute Units of the Navi 33 chip of the RX 7700 XT and the 96 of the Navi 31 chip of the RX 7900 XTX. The average duration would be 64 physical units, but we do not know how many of these will be idle in the final versions. In any case, it shouldn’t take long to see these graphics cards, especially since their NVIDIA counterparts are already available or are only a few weeks away from being available in stores.
