AMD Zen 3 (5000 Series), rumored 17% IPC gain.

so being on a ryzen 1600 + b350 board , which does support the 3000 series with a bios update. Wonder if its better to upgrade to a b550 + ryzen 4000 or just get a much cheaper 3600/3700x when the price drop happens.

The tomahawk max page states it will be covered for future CPU upgrades.

taken from this page.

e) You want a value-oriented motherboard that’ll support not only the latest AMD releases but will also have you covered for all future AM4 product releases.

Infact this covers all MSI max boards stating support for future AM4 CPU.

Ryzen 7 4700X will be faster,but it will be more expensive than a Ryzen 7 3700X,and then you need to include the price of a new motherboard too.

You could always sell your board and buy a new one if you think it turns out to be worth it

It's virtually certain that most 3xx and 4xx boards with a large enough flash memory pool will get Ryzen 4xxx support.

Non-story. 3xx doesn't have official Ryzen 3xxx support either.

I suspect its a case of saying AMD will not support it so they are not pursued by all and sundry if their board will not work.
However nothing to say the motherboard suppliers cannot make a bios for it to work.

In my case,as I have a higher end 400 series mini-ITX motherboard,so it will lose a lot due to this,and the replacement will probably cost a fair amount for similar features. The B450/X470 motherboards won't be worth much IMHO once Zen3 is out.Then add the additional cost of the Ryzen 7 4700X over any discounted Ryzen 7 3700X,and the fact I see the platform being EOL,the next generation after,it's probably not worth it for me. If it was a slot in upgrade I could justify a Ryzen 7 4700X,but I might as well wait and see how Zen4 looks,and move on from there. I can see Zen4 being an improved Zen3 with more cores because AFAIK it moves onto 5NM.I will have to get a new CPU and motherboard anyway. The RAM might be an additional cost,but I might as well save up for that.

Well i'm hanging on to my B450 gaming pro carbon board and will hopefully drop in a cheap 3700/3800x when the Zen 3's arrive! That will do me! AMD just lost a Zen 3 CPU sale.

Eatchipz · 7 May 2020 at 22:51

Sure AMD told certain board manufacturers who had released BIOS to drop PCI Express 4 support on X470 and all of them complied. I can see it being the same here.

AMD are not going to lock out 80% of potential CPU sales by preventing older chipset customers upgrading to zen 3 without having to buy a new motherboard which many are not going to do for one generation of CPU.

Can anyone find any Aida64 benchmarks from reviewers for latency on the 3300x?

Edit: Found it. https://www.kitguru.net/components/cpu/luke-hill/amd-ryzen-3300x-cpu-3-3100-review/5/

I feel like 71ns is not that good. I honestly thought with how the 3300x was designed the latency was going to be under 60ns. Maybe 3,600 RAM will get it lower?

I was wondering this as it should be a good indication for zen 3.

How would we explain it away. It has a single CCX but still 71ns latency lol? Maybe a poor memory controller

Heck I get 62ns on a 3950x with 3600 CL14 RAM. Youd surely think the 3300X would do better than that

The IMC is on the IO die, which is external to the CCX, its still the case with the 3300X, whats different is all the cores are in a single CCX so its the "Inter-Core" latency that's much better. not the Memory Latency as that still needs to move outside the CCX.

It'd probably be ~60ns on tuned 3800CL14 with matching 1900FCLK ... if that chip would do it. That would be outstanding for Zen 2. That 71ns is on untuned 3200CL14 & 1600FCLK.

Reduced latency on the Ryzen 3 3300x is having an effect. Both Gamersnexus and HUB showed some impressive improvements clock for clock between the two CPUs:

https://www.youtube.com/watch?v=4dY64Zy1Mxw

Some improvements are over 20% clock for clock over the Ryzen 3 3100.

I didnt bought a 570 because i never expected them to pull this **** and i wouldnt make use of pcie x4, they literally pulled a intel move, cant wait to see fanboys trying to spin this **** move.

Giving 2/3 gens of support to 1st and 2nd gen chipsets isn't pulling an Intel.

If you want to see what pulling an Intel looks like, just take a look at Z390 and Z490.
