AMD - Zen chitchat

[CAT-THE-FIFTH]

I have a bad feeling if the rumoured Zen2 refresh is locked to B550,the new APUs will also be locked to B550.

Looks like the 300 series chipsets might not work with Renoir:

Apparently the existing ASRock Deskmini will need to be refreshed for Renoir.

Edit!!

Also looking at pricing,it seems the B550 motherboards are more entry level X570 pricing,looking at where they are being pitched. It would not surprise me if A520 motherboards get close to £100.

Its not locked as such but the bios size limitation. Amd could split the microcode so that there is two versions but you can just imagine mobo makers not using both versions in two different bios files. Also you can see people downloading the wrong bios

AMD has locked it out on purpose by not giving the microcode out. Also Zen2 refresh and the APUs use Zen2 cores,so there is zero reason to lock them out from B450,as the CPU base microcode is the same. All the laptops with Zen2 APUs use 400 series chipsets.So if they start locking out a 100~200MHZ higher Zen2 and the APUs,then it's just segmentation.

Edit!!

Also if you listen to the latest GN video,its a load of bunkem,as there are 32MB B450/X570 motherboards which work with Zen+ anyway.

I was thinking of getting a Ryzen 7 3700x, is it worth waiting now until the next series comes out?

Over your Ryzen 7 1700X the Ryzen 7 3700X would be noticeable. But Zen3 might move to a single CCX design which will help with gaming. Only problem is Zen4 is probably DDR5,so I don't know what the upgrade path is for B550/X570 after this.

Ok thanks, I might wait a while and see what develops

I think with all this RT stuff,and the move to Vulkan and DX12,games should thread a bit better. So although I want a better CPU myself,all this stuff with the lockout of CPUs,made me realise,maybe I need to save up more for a better graphics card.

I currently have a GTX1080 FTW2, was thinking about an RTX card and wondering if its worth selling mine and getting something like an RTX2070 which has slightly better performance and has RT, though not entirely sure of the benchmarks with RT turned on

Wait for the Ampere/RDNA2 based graphics cards - Turing is a more of a test case for RT. The newer generations will be better at RT IMHO.

Read some reports that could possible be September 2020, likely?

It's likely, but no-one can say any more than that

[Jonj1611]

Obviously lol

Indeed. It's worth bearing in mind that DDR5 will be mega bucks over the same capacity DDR4 when it first comes out and will probably take a very long time for the price gap to approach DDR4 prices. IIRC DDR4 was twice the £/mbyte over DDR3 when it first came out and it took 5 years plus to be within 10%

Essentially a decision to go B550/Zen 3 means any upgrade to a new architecture requires new CPU, motherboard and RAM. Waiting for Zen 4 in 2022 means paying through the nose for memory.

It's not an easy decision. If I personally had a 1700x and x370 I would not even consider the B550 until the Zen 3 equivalent comes out and see how it performs for real. If it does hit the rumored 20% uplift and that 20% were to apply to my specific workloads I'd just save the money on a new motherboard and also get the cheaper 3700x

One comment on the price they estimate: "I'd say about 200, a steal if it comes at that price."

A pretty dumb comment. So an APU with 8 Cores and graphics will be cheaper than an 8 Core CPU without the silicon for graphics that runs at the same base clock but lower boost.

Of course it would be a steal if it's some imaginary stupidly low price!
