AMD Ryzen "Picasso" APU Clock Speeds Revealed
AMD is giving finishing touches to its Ryzen 3000 "Picasso" family of APUs, and Thai PC enthusiast TUM_APISAK has details on their CPU clock speeds. The Ryzen 3 3200G comes with 3.60 GHz nominal clock-speed and 4.00 GHz maximum Precision Boost frequency; while the Ryzen 5(?) 3400G ships with 3.70 GHz clock speeds along with 4.20 GHz max Precision Boost. The "Picasso" silicon is an optical shrink of the 14 nm "Raven Ridge" silicon to the 12 nm FinFET process at GlobalFoundries, the same one on which AMD builds "Pinnacle Ridge" and "Polaris 30."
Besides the shrink to 12 nm, "Picasso" features upgraded "Zen+" CPU cores that have improved Precision Boost algorithm and faster on-die caches, which contribute to a roughly 3% increase in IPC on "Pinnacle Ridge," but significantly improved multi-threaded performance compared to 1st generation Ryzen. Clock speeds of both the CPU cores and the integrated "Vega" iGPU are expected to increase. Both the 3200G and 3400G see a 100 MHz increase in nominal clock-speed, and 300 MHz increase in boost clocks, over the chips they succeed, the 2200G and 2400G, respectively. The iGPU is rumored to receive a similar 100-200 MHz increase in engine clock.

Also, do we know these are the final clocks?
Right now, it seems like AMD has seeded CPUs/APUs with different clock speeds to different customers/partners, so don't take anything for granted for the time being.
I want to know about the IGP specs. Do we get Navi or is it still Polaris? Will they raise the amount of cores or will it still stay at 11 max?
Also increasing the amount of GPU cores wouldn't help much if the GPU is limited by the system ram bandwidth anyway.
As memory compatibility improves its easier to feed the gpu.
3466 was only b die but now hynix and micron kits manage it easily at cl16 even in high densities.
Waiting for 7nm APUs
:)
The second was 1st generation Ryzen and was released just prior to the second generation of Ryzen...
I don't think the iGPU has really gotten all that much better... The only thing that seems to really progress is the CPU cores.
Maybe they'll really take off with DDR5
EDIT:Yeah so far. The chiplet design they have started using might help them with that issue as they will no longer need to design a seperate AMD APU chip instead with the Zen 2 based APU's we are likely to see AMD have three chips on their AM4 and Notebook APU's. Those being the I/O chip, Zen 2 chip, and a Navi chip. Thanks the this AMD will only need to have the seperate chips ready to make an APU instead of a single monolithic design that incorporates all of those chip designs into one.
As you can tell from my specs, I have a i7-5775c. It is very similar to these Ryzen APUs, with 4 cores/8 threads and a beefier than usual iGPU. The Vega 11 GPU part in the Ryzen is 50% faster, but the CPU part of my i7 is 20-30% faster. When these come out, the 3400G will trail my CPU by only a little bit and provide maybe 70% better GPU performance. AMD took 4 years to get there but they are finally on par with the best APU Intel has ever put out, and at a considerably cheaper price.
Invest in a brand/nomenclature. Promote it. Try to to shove as many unrelated products under the same umbrella.
