Just a feeling. I'm talking more about responsiveness than absolute performance. The 7545U should feel much snappier. In case Chips and Cheese does a proper article on it, we will surely get some juicier benchmarks.
DPC latency looks good even on Intel, but that one is more dependent on laptop model than CPU used.

I just checked and I can buy some Ryzen 5 7540U model, but they are >1000 euro.
That's just too much for this APU.

Edit: My mistake, 7540U is the standard version. 4CU IGP is utterly weak, so waiting only because of that is not reasonable.

Question is what will they do if a Zen 4 core is not functional, will they release a 4C/8T Zen 4c SKU limited to say 3.2GHz or rather a 5C/10T with 1 Zen 4 + 4 Zen 4c, the latter would be more relevant on a perf and revenue POV.

They have already released 4C/8T part where is 1 regular Zen core and 3 c-cores.

Little Phoenix for a Ryzen 5 7500G? 4CUs for a Ryzen 5 G? unacceptable, and i hope everyone agrees this time. I can accept it with the 7300G, to a point.

Unless the price is really really good, but i doubt it.

7500G is basically a better 12400. You don't have to accept it. Majority of people just have to.

Should It matter that It only has 4CU?
It's a 6C12T Zen5 Zen4 APU so It will be likely called as 75**G.
What matters is the price.

Gaming performance despite only having 4CU should be comparable to 8CU IGP in 5700G.
How is that possible? Simple, higher clocks and much better architecture.
Example: 4CU 3GHz RDNA3 vs 8CU 2GHz Vega

edit: fixed Zen5 -> Zen4

Im sorry but no, that excuse not longer works when all AM5 socs already have a non-gaming IGP.

STOP defending this. I warned this would happen when people defended the Renoir igp shink. I was completely right.

It's fine for everything but gaming.
Like... the regular AM5 CPUs?... yeah, no.

4CU is even enoght to beat a +2 year old 5600G? That has the same igp as the +3 year old 4600G that performs about the same as a +5 year old R5 2400G? seriusly. No more of this, do not defend these anti-consumer moves!

Matching 5700G would be fine for an 7300G (and something tells me it might not have all 4CU enabled), but for a AM5 Ryzen 5G? That would be like what? 10% increase over the 5 year old 2400G/3400G? And this is best case escenario, because im petty sure you need 6 CU or some really, really high clocks to match the 5700G @ 2GHz.

When we know the prices then we can compare them to the AM4 combos with 5600G/5700G, and even the older ones with 2400G/3400G, and im petty sure than once we do that it is going to be very clear this is not OK.

7600 starts at 220 dollars. 7300G probably starts at 120, that's the difference. If you want to game, the mining craze is long time over, get 5500+rx580 for 200 dollars, it'll be cheaper and a lot faster

The 7300G should be fine. But launching a 7500G in 2024, with the IGP performance of a 2019 3400G? That alone is very bad. And lets see about pricing but it is likely that the overall combo price to be higher than current 5600G/5700G, this is not OK in any way.

The market will determine if that is acceptable or not. No need to get all worked up about an unreleased part. The rumored specs show the 8700G having 12CU's and 8600G as having 8CU's. I'm sure they'll be fine.

Big mistake from AMD , they come very late, dunno who take the decisions there but affordable APUs should be a first concern, it s by launching such products that they got AM4 success on the long run.

The 7600 has been available all year and the MSRP was $229. Any lower and they needed Little Phoenix.
