Seven AMD Ryzen 4000G APUs leaked by Biostar

[HEXUS]

Meanwhile rumours about the clock boosted Ryzen 3000XT CPU series start to swirl.

Read more.

I'm looking at the APUs for a possible media server upgrade. The Vega cores work well for transcoding using VAAPI under Linux and a 4c/8t upgrade at Ryzen 3 will be a big uplift over the Skylake era Pentium 2c/2t that currently does the job.

My only hope is that they release a new value series motherboard ranger fairly soon to replace A320. I know it's slated but not seen a release date yet.

And with one bound...

I suppose this was to be expected - AMD just needed to stretch their legs a little to outpace Intel's latest, curate's egg, launches.

I also anticipate some price adjustments coming down the line for existing stock.

I also look forward to some 3900XT comparisons with Intel!

[edmundhonda]

Are we assuming those XT chips are all single CCD, 8c/16t parts? That makes the most sense for a gaming-centric range, doesn't it?

edit: Maybe not, since that r5 3600xt would then just be a slightly boosted r7 3800x. Hmm.

Will only work on B550 and A520,and the prices have been leaked. The cheapest Asus B550A Prime is $130(so around £130 here),and the Asus B450A Prime is around £85. If that is applicable to other 500 series motherboards from other companies, the target market of the APUs,will end up probably using A520 motherboards,if they end up being most of the sub £130 AM4 motherboard market. So no overclocking and AFAIK,I don't think the A series motherboards support above 3200MHZ RAM either.

Whats the difference between the Pro 4700G and the normal 4700G?

ECC memory support mostly.

ECC memory support mostly.

Always wondered what product AMD thought enabling memory support in APUs would threaten. They do it in all the other chips and have for years, just not APUs. Would otherwise make for a cracking small server chip, where I don't really want to add a GPU on a machine that is largely working headless.

Wouldn't be so bad if I could actually buy a new Pro chip, but I've only seen them as pulls on Ebay

Is for OEM's that's why....

I know that the Pro chips are for OEMs, but AMD have done Pro versions of the non APU like the 1700 and that didn't involve mucking about with fusing off ECC on the non pro version.

I can't see it. There's a bit of rearranging with SATA but the only significant change is PCIe 4.0 from CPU to the first PCIe and m.2 slots, right? It doesn't even touch the chipset!

There's an Asus Prime B550M-A board with Intel 802.11ax on board, which might be part of what makes that one in particular expensive (if that leak is accurate)

The Asus B550I Strix is $229,which would is around £230,ie,around X570 mini-ITX pricing. The Asus B450I Strix I have cost me £150.

The $134 figure is for the B550M-A version,not the Wifi version:

The B550M-A is the second cheapest B550 motherboard in the Asus range,and you can tell by the use of the ALC887 codec too.

They've already backtracked on 4000 series support for B450 boards so its pretty likely that some B450 board will support them via bios update, whilst at the same time removing support for older CPUs as a result.

Am I missing something, or are the onboard APU graphics less core-count than before?The 2200G and 3200G were each Vega 8, whereas the 2400G and 3400G were both Vega 11. Here the top-notch 4700G is only 8, and the rest of the stack go down from there? With he "equivalent" 4200G only being Vega 6 as opposed to Vega 8 before?

Did I not read somewhere that the 4000 series APU's were based on Zen 2, not the new Zen3 architecture?

Yes, the APUs have been last for each Zen gen so far and that's likely to continue.
Not only are they more complicated to integrate, they are also not as versatile. The Zen2 chiplet was used for Ryzen 3000, Threadripper 2, EPYC. The APUs will only be used for mobiles and some desktops.

No, this is correct. For the Renoir APUs they went for loss cores running way faster.
The 2000s and 3000s series ran at around max 1300MHz, 4000s APUs run at max 1750MHz.
Theoretical max GFLOPS has actually gone down a bit (1971 down to 1792), so far the benchmarks have favoured the new smaller, faster approach.
Guess there is only so much space and 7nm is still expensive, as normally you'd think for power-efficiency wider-slower is usually better.
