Hardware & Technical GPU Upgrade: RX Vega 64 to 5700XT

Been a while since I saw a reference Vega 64, but it's good to see you compared two reference editions.
Will you do undervolted results as well?

I could do - but I'll probably wait for a newer driver release - the overclocking is apparently a bit iffy in 19.7.1.

From what I've heard, "iffy" is a real understatement. :D
Though I've seen a good results "overclocking" the card simply by ramping up the fans and setting the power target to +50%. The auto boost is apparently quite good at maxing the GPU out.

Okay, I hope Robert won't mind but I'm going to use this thread to keep the 7nm info contained.

I couldn't wait so I devised a cunning plan.
Because the R5 3600 is still (after four days, grr) the only CPU readily available at my place (the others are a 1 week order), I decided to buy the 3600.
Once partner 5700XTs are available and I get one, I'm going to use this CPU and my Vega to build a mildly interesting low budget gaming PC and sell it, then buy an X570 and R3700X.
Muehehehe.

Anyway. I now have some comparison of CPUs so I thought I'd share, though my old 1500X is probably not so spread among the community so who knows if this comparison is worth something.
Well, if anything, it shows that 1500X is NOT enough to power a Vega 56, apparently.

My setup is:
MSI B450M Mortar
Crucial 2666MHz 14-16-16-32 RAM
Vega 56 (Technically Vega 60, after gaining some cores by slapping the Vega 64 bios on it) 1622MHz core, 1800Mhz Memory

Everything is left the same, the only variable is:
Ryzen 1500X @ 3.9Ghz with Noctua cooler
vs.
Ryzen 3600 @ 3.7Ghz with stock cooler (I'm an idiot and couldn't find my thermal paste, so I couldn't re-apply the Noctua. And I don't want to overclock it on the stock cooler)
So two extra cores and two years of development.
Here goes:

Encore:
136961

136962

Time Spy:
136963

136964

Firestrike Ultra:
136965

136966

And most importantly (For me, anyway) - Assassin's Creed Odyssey (1440p, Ultra Settings, except Volumetric Clouds):
136969

136968

So, by and large - a big win for under 200 quid.
Encore didn't really do much. Apparently that one is pretty much a GPU hog and was quite close to the max already.
3D mark scores are pleasing. The CPU score in TimeSpy and Physics score in Firestrike really speak loads.

But mainly the ACO result is awesome. Previously I couldn't play on the settings I've benchmarked it on, naturally. Now I can!
My monitor has a Freesync range of 55-75Hz, which means it can now hold that range and deliver stutter and tear-free experience, unlike before. I don't need MUCH more. As my monitor is 75Hz, I think that the 5700XT will give me that final push where I'll be able to max out the game completely and I wouldn't even really need to be getting that 3700X at all. I would, though, probably benefit from buying some nice 3666 Memory kit.

So I'm quite happy with this little new CPU.

I hear you are better off with 3200 memory and crank up the Infinity thingy and lower the ram timings. I just ordered the 3600, a new mobo with 3200 memory with the intention of lowering the timings. Also, I hear you can overclock the 3600 with the stock cooler. it's supposed to be pretty decent.

I've got Ryzen 3600 and after some fiddling around, I found out that trying to overclock it is kind of pointless. You are much better off simply installing the Ryzen Master and turning the Precision Boost Overdrive on. It will pretty much max-out your CPU on its own. No work required. With a stock cooler installed (because I couldn't find a thermal paste at the time) it boosted to about 4.2GHz. Now that I have my Noctua cooler back on, it's boosting to something over 4.3 all core with the best core sometimes boosting close to 4.5GHz. You won't get it any better with manual overclocking.

I have to say, though, 3600 is a pretty little beast. In some games I gained somewhere between 15-20% FPS compared to my old 1500X with the same GPU and memory (Vega56 and 2666Mhz RAM).

Hardware Unboxed did a nice RAM testing, yesterday (I think) and yes, pretty much any RAM above 3200MHz is fine with 3800MHz being the sweet spot, because the infinity fabric can be overclocked to max 1900MHz so it runs at 1:1 ratio with 3800MHz dual channel RAM. Anything above that is pointless.
But as you rightly say, it the latencies that matter a lot. I'm actually thinking of buying a 4GHz or 4.4Ghz kit and underclocking it to 3800MHz with some nice timings. 4.4GHz CL19 should be able to handle 3800MHz CL16 or even CL15 at which point you have a beast of a setup.

Hopefully we see the 3rd party 5700xt cards any day now bc my impulsive side is having a tough time with this one. The reference 5700xt is now marked down to $385 on Amazon......ugh I really want to click that buy button but good sense says wait.

Yeah, me too.
Some devious part of me wants to grab the reference model and the waterblock from EK and build something awesome. :LOL:

Though the reasonable part of me wants to wait for Sapphire or ASUS boards with decent cooling of their own.

It's hard, man. :D

I can't justify a full-cover block on anything other than the highest-end of cards.

Increasing the cost of a part by at least 25% (if you already have a loop to attach it to), and possibly much more than that (if you don't), ~10% more performance and reduced noise levels, is a tough sell...especially when non-reference coolers will get 2/3rd of the way there for a much smaller increase in cost.

Now, I have enough parts laying around that I could do a GPU only block and epoxy some sinks to the VRM and GDDR6 for no additional investment...other than a lot of work, of course.

Info and pictures of the various third party cards seem to be coming in pretty frequently these past few days, so the first ones should be on shelves within a month.
From Sapphire, there's only info on the Pulse version yet, so it's still the waiting game on Nitro or a liquid-cooled Toxic.

Yes, that's exactly why I'm reluctant to do that.
Although on the other hand, 5700XT technically IS the highest end AMD card, now that VII has been discontinued.

Still it's not the economic choice, of course. For a 5700XT with full block and Corsair hydro kit, I could buy an RTX 2080. But honestly, I consider PC gaming (and PC building) a proper hobby of mine. And once something is a hobby, you don't HAVE TO do reasonable choices. Or at least you don't have to justify them. :LOL:

If I actually went for this option, my build would be even more ridiculous, though, because I'd likely watercool the CPU as well, which on Zen2 makes even less sense.

I would be surprised if Navi 10 is not the mid-range frontrunner for AMD GPU on 7nm.

Of course it is. Why would they bother with a completely new architecture, otherwise.
The only question is when are they going to introduce the larger chips. They basically clogged TSMC's pipelines with Zen 2

Well, AMD have licensed RDNA to Samsung....

Interesting. Didn't know that. That's actually quite good for AMD.
But do we know whether Samsung will be manufacturing something for AMD or it's for their own needs?

I think that the licence is for phone related use - however Samsung do have a 7nm manufacturing facility.
