AMD Ryzen 4000: More Desktop APUs Come Out of Hiding

It's only a matter of time before AMD launches the its Ryzen 4000-series (Renoir) APUs for the desktop. With the latest benchmarks spotted online, it seems the chipmaker is cooking up some 7nm APUs for the commercial market as well.

We've already gotten a possible sneak peek of Ryzen 4000 APU performance via the Ryzen 7 Pro 4700G, Ryzen 5 Pro 4400G and Ryzen 3 Pro 4200G.

However, the latest 3DMark submissions (via @_rogame) revealed three new Ryzen Pro 4000-series SKUs that weren't that weren't previously known. 

It's uncertain if the Ryzen 7 Pro 4750G, Ryzen 5 Pro 4650G and Ryzen 3 Pro 4350G processors will be available to the general public. Given their model names, the trio of Zen 2 APUs could be OEM-exclusive parts. Like always, take the submissions with a pinch of salt, since AMD hasn't officially detailed its Renoir lineup.

AMD Ryzen 3 Pro 4200G4 / 83.80 / 4.102 / 461,70065

*Specifications are unconfirmed.

If these specs are accurate, the Ryzen 7 Pro 4750G will cement itself as the flagship APU for the Ryzen Pro 4000 lineup. The eight-core, 16-thread chip surfaced with a 100 MHz higher base clock in comparison to the Ryzen 7 Pro 4700G. The graphics configuration seemingly remains unmodified.

At first glance, the Ryzen 5 Pro 4650G and Ryzen 3 Pro 4350G appear to be a replica of the Ryzen 5 Pro 4400G and Ryzen 3 Pro 4350G. The clock speeds fall in line with leaked Renoir specs and information on Ryzen 4000 shared via Biostar listings

For the Ryzen 5 Pro 4650G, we're looking at a six-core, 12-thread setup with a 3.7 GHz base clock and 4.3 GHz boost clock. The Ryzen 3 Pro 4350G should leverage four CPU cores and eight threads that run with a 3.8 GHz base clock and 4.1 GHz boost clock.

Renoir should finally bring parity with AMD's other processor offerings to the APU line. The Zen 2 processors will come from the same TSMC 7nm FinFET furnace and usher designs with double the cores in comparison to last generation's Ryzen 3000-series (Picasso) parts.

AMD Ryzen 4000 Release Date 

While Renoir's specifications are seemingly exposed, there is still a bit of mystery surrounding the desktop APUs' launch. 

Many speculated dates have been thrown around over the last couple of months, including some pointing to a July launch. However, AMD hasn't provided any evidence that confirms or disproves this.

    I wish one or two of these came from the factory having a 35w TDP, or 50w . Could be anything, just something lower than 65.

    64 watts it is then!

    well they still dont target a true SFF with those.

    guys
    AMD Ryzen 3 Pro 4200G
    AMD Ryzen 3 Pro 4350G
    seems identical.

    are those 4ccx vs 2ccx configs ?

    TDP are THERMAL solution design power, not electrical power. They are meant as guides for heatsink selection and since it is trivial to design heatsinks capable of handling 65+W in desktop form factors, there is no point bothering with TDPs below 65W even for chips that only draw 35W.

    You could Underclock your CPU if you wanted to reduce the TDP, to whatever you wanted.

    Set the CPU Multiplier to a smaller value, if your CPU Frequency is 4.5 Ghz then the multiplier would be 45 (probably). Reduce it to as low as you want to go.

    The lower-end SKUs are well below 65W average electrical power under stock conditions, the 65W Thermal Design Power is simply because going any lower than 65W for desktop heatsinks yields no meaningful savings in desktop heatsink design and manufacturing costs: a 35W heatsink might shave 5mm on the extruded aluminum heatsink height, which is only 10-20 grams (under $0.05) worth of material.

    Mobile chips get multiple fine TDP brackets because cooling solutions are application-specific and a few watts difference can have a substantial impact on design possibilities in heavily space-constrained designs like laptops.
