After what feels like an interminable wait, AMD's Navi 32 GPU is finally starting to make its appearance. This is the second stage of the RDNA 3 graphics processor and the second ever to use AMD's new GPU chiplet package technology. The Red Team now seems to be focusing on the mobile market, as evidenced by the fact that the leaked silicon is a laptop version of the RX 7800 series.

However, this means that we will likely still have to wait a while for desktop cards in RX 7700 or RX 7800 trim.

Twitter leaker All_The_Watts listed the expected specs for five different Navi 32-based mobile graphics cards. While there is no way to be 100% sure of the veracity of these rumored specs, they are quite likely and seem to be consistent with the previous generation of AMD mobile GPUs.

They also posted a shot of a 3DMark Time Spy benchmark that appears to be from an RX 7800M XT run, which far exceeds the best performance of the previous generation of laptop Radeon chips. In other words, it offers the desktop performance of the RTX 4070.

The RX 6850M XT averages about 11,000 points, while the RTX 4070 is at the same 17,800 level. This speaks well for the Navi 32 silicon performance, which is a cause for concern given how far behind AMD was with the second-best RDNA 3 GPUs.

The RX 7800M XT is the top mobile chip in the next generation of Radeon and the fact that it can deliver this level of performance at 189W total board power is impressive.

If, as expected, the RX 7800 XT has the same basic GPU architecture, but with higher clock speeds and more power, this should translate into superior desktop performance as well. [However, this is a heavy "should," and there is no guarantee that providing more power to the Navi 32 GPU will significantly improve desktop GPU performance. Indeed, current experience with RDNA 3 chips, both monolithic and chiplet, has not shown any particular suitability for ultra-fast clocks. In any case, the figures do not exceed the 3 GHz expected for the Radeon RX 7000 series chips.

So far, the high-end RX 7900 XTX and RX 7900 XT cards have a somewhat limp Navi 31 chip, while the lower-spec RX 7600 has a Navi 33 GPU The middle order of Radeon cards is conspicuous by its absence, Some rumors

suggest that the performance is not what AMD had hoped for.

Unless the Red Team can use more power on the desktop to significantly increase clock speeds, the RX 7800 XT will end up performing like the RX 6800 XT. Also, in terms of cross-generational performance gains, it is not very good.

Still, if we stick to the mobile aspect, it bodes well for the gaming performance of AMD-powered laptops. For reference, the Time Spy score is only slightly below the average GPU score of the RTX 4080 laptop chip (which is close to the RTX 4070 Ti desktop part), which looks great to me.

The full lineup of rumored mobile Radeon chips is as follows:

The RX 7900S looks a bit odd given that it has the same essential specs as the RX 7800M XT, but with a lower power consumption profile; the RX 7700 M and RX 7800S are the same, but the less said about AMD's current naming conventions the better; AMD's laptop chip nomenclature is almost baffling (it requires a coding wheel), and the graphics card names really don't say much.

But my mother said, "If you don't have anything nice to say, don't say anything at all." If I had strictly followed that advice throughout my career, though, I wouldn't have many publications today.

Anyway, depending on the price of these Radeon machines, the RX 7800M XT could be the GPU you want at the center of your next gaming laptop. the RX 7800M XT offers serious performance and efficiency. the RX 7800M XT is a great choice for a gaming laptop, and it's a great choice for a laptop with a lot of features. It will be interesting to see how close the lower-power RX 7900S is performance-wise for a 135W GPU, but for high fps games, the RX 7800M XT is probably the better choice.

And given that benchmark scores seem to be out right now, it may not be long before we know exactly what it is capable of in the real world.
