Petty sure its general score, 3300 general score its petty much spot on with R5 1400 + GT1030, and a bit worse if its graphics only. We need to consider the R5 1400 is slower than 2400G CPU only as well.
This is what AMD has been telling so far, a Timespy result equal to a I5-8400 + GT1030, the thing is, there is no I5-8400+GT1030 timespy result in the 3dmark database, somehow no one has been dumb enoght to pair a 8400 with a GT 1030 and upload a result. There is a single Firestrike result... so this is kinda an imaginary enemy AMD invented here.
Anyway, everything seems to point Stock+DDR4-3200 equal to GT1030 in 3dmark for the 2400G, what would translate to slower than GT1030 in games. I really hope is not that way because that would be the worse APU to dGPU perf ratio in the history of APUs.
