Zen4 6cores = Ryzen 8600g with low frec --> at best
+
Navi3 1792 SP = Radeon 7600 cut out in cores and cut out in frequency = less performance --> ~ RX 6600 (of 2021)
The entry-level range that existed 3 years ago. It's fine, but it's not that exciting.

What frequency? I didn't write any. I don't understand you.
I'll summarize:
We can know that the frequencies are lower than those of the Ryzen 8600g and Radeon 7600 because of the 30W and 110W power consumption. (Steam says they are 4.8 GHz & 2.45 GHz) (8600G = 5GHz & RX7600 = 165W & 2.65GHz)
The RX7600 has 2048SP, while this one only has 1792SP. That's 12.5% less.
They say it's semi-custom, but I find it strange that it has DDR5 and GDDR6 controllers. I wouldn't be surprised if they are reusing half-baked 6nm Navi33 from the RX7600 that they haven't sold, because AMD is experiencing record low GPU sales.
If it really is semi-custom, it will probably be 4nm (with some kind of new packaging like the AMD Halo), so it consumes less than RX7600, but even so, Steam says only 2.45GHz.
And the 8GB of vRAM tells us that it will have a 128b bus.
I said , in the best of cases, because instead of being an 8600G (with little cache3, 16MB, and worse performance than a Ryzen 7600),,, it could be something similar to Phoenix2 (Ryzen 8500G) that has 4 Zen4c cores, tight and hot, which means that they only support lower frequencies.
So, it's better if they are "normal" Zen4, from laptops.
To make it clearer:
Steam (year 2026) = Zen4 6cores 4.8GHz + Navi3 1792SP 2.45GHz & 128b to the RAM (~288GB/s)
Radeon RX 7600 (year 2023) = XXX + Navi3 2048SP 2.65GHz & 128b to the RAM (288GB/s)
Radeon RX6600xt (year 2021)= XXX + Navi2 2048SP 2.55GHz & 128b to the RAM (256GB/s)
PlayStation 5 (year 2020) = Zen2 8cores 3,5GHz + Navi2&3mixed 2304SP 2.2GHz & 256b to the RAM (448GB/s)
XBOX Serie X (year 2020) = Zen2 8cores 3,8GHz + Navi2 3328SP 1.8GHz & 320b to the RAM (560GB/s)
PlayStation 5 Pro (year 2024)= Zen2 8cores 3,8GHz + Navi2&3mixed 3840SP 2.2GHz & 256b to the RAM (576GB/s) + DDR5 controller (¿32b?)
AMD HALO (year 2025) = Zen5 16cores + Navi3.5 2560SP (1.3-¿2.9?GHz 45-120W) & 256b to the DDR5 (256GB/s)
