The RX 7700 and RX 7600 will have PCIe 4.0 x8, how is AMD going to fight like that?

It is confirmed. AMD is going to bet on reducing costs in its mid-range GPUs and in something as basic as the data bus available for them. The confirmation comes from various parties that are even providing data attached to them, but what is certain is that the RX 7700 and RX 7600 will be PCIe 4.0 x8 and not x16 as expected. Can AMD fight the RTX 4070 and RTX 4060 like that?

Well, apparently it is going to be able and against all odds and filtration it seems that everything is due to an adjustment of range and chips. How is it possible that the mid-range has gone straight to half the fastest bus available for graphics cards today? saving PCIe 5.0which only has it Chinese MTT 80 and which is worth nothing beyond marketing, AMD is being much more objective and intelligent.


AMD RX 7700 and RX 7600, PCIe 4.0 x8 bus, a good option?

Taking into account the multitude of tests that have been done with current high-end graphics cards, such as the RTX 4080 and RTX 4090, in different bus configurations and in different versions, all of them have shown that the PCIe 4.0 x8 or PCIe 3.0 x16 is enough and by far to handle the data they need. The differences compared to PCIe 4.0 x16 are within the margin of error, so with this in mind, mid-range graphics cards with much less power than those mentioned are more than feasible to work with. PCIe 4.0 x8.

And that is what AMD had to think about, because the confirmation that the RX 7700 and RX 7600 will arrive like this is a fact on the same level as the fact that NVIDIA is going to launch the new AD104 with PCIe 4.0 x16 for the RTX 4070. Why is this done?

Lower manufacturing costs, cheaper graphics cards

It seems that AMD is going to “pass” all that “bad press” that will attack this fact. The reasons for doing so are different, but we do know that Navi 32 will not be the one that will go on these RX 7700 and RX 7600 with PCIe 4.0 x8. The chosen chip will be ship 33 and, therefore, will compete with the AD106 and AD107being the commented Navi 32 of the RX 7800 XTX and RX 7800 XT the one in charge of doing it with the NVIDIA AD104 in its different versions.

AMD’s strategy, apparently and according to the latest rumors, will also continue for laptop GPUs, where this ship 33 will also include PCIe 4.0 x8 in the teams that comprise it. The reasons are the same as on desktop: to offer a series of models of graphics cards with a lower cost for manufacturers, so that the price can be pushed down.

The problem, if there is one, is that NVIDIA is going to do the exact same thing. That is to say, the AD107 and AD106 will also arrive with PCIe 4.0 x8 for the same reasons that AMD has chosen. Therefore, and in principle, if there is no surprise, AMD will be able to fight against NVIDIA with the same weapons, be it performance or price, even if the ranges do not match on paper (RTX 4050 Ti and RTX 4050 vs RX 7700 and RX 7600).
