I heard that an RX Vega 56 OC'd can be better than a stock 64. Is this true? I wanted to get a 64 but the extra money seemed a little ridiculous for the small increase in performance(especially since a 56 OC'd might be better).

Since a stock 64 is supposedly worse than an OC'd 56, does that mean that an OC'd 56 could match a 1080(and be better than a 1070ti) since the stock 64 is just below a stock 1080(and especially since the newer drivers from AMD make it perform better)?

I've seen through RivaTuner OSD that neither my GPU nor CPU are being tasked to 100%, but there are still stutters and fps drops. A processing unit doesn't have to be tasked to 100% to be bottlenecking you, correct? Can you guys tell me which processing unit(Vega 56 or Ryzen 5 1600) is more likely to be bottleneck me when I play games like Total War, Battlefront II, Battlefield 1, Fallout 4, CSGO?

Also, is my power supply enough to handle an OC'd Vega 56? And, if you guys can, can you guys tell me how much farther I should overclock this Vega 56(it's coming OC'd already but I want to know if I can take it further).

The Vega 56 is already on its way and I checked PSU calculators, but I just wanted to be sure.

A 56 overclocked to (or beyond) 64 clocks, will rival the 64, if not beat it in most tasks/games/applications.

As for the direct comparisons with Nvidia cards, it's not *that* simple that one card is "better" than another inherently. A lot will depend on the applications/games, DX version used etc.

At launch, a 56 fell a little short of a 1070 & a 64 a little short of a 1080 in gaming for the most part (excluding DX12). With driver maturity etc, I would think that gap should be pretty much eliminated.... so not unreasonable, in a general sense to think and OC'd 56 will perform roughly on par with a 1080 stock, or an OC'd 1070TI.

All that being said, how much did the 56 cost? They're still going for ~$500 last I checked.
Unless there's any particular reason you needed to go the AMD route... a 1080 was probably within budget and could OC beyond OC'd 56 performance?

I went with the OC'd Vega 56 because it simply fits my build better(AMD Mobo and AMD CPU)+my mobo only supports crossfire(so if I wanted to do that down the line I would want to go AMD). Do you think my PSU is enough for the GPU?

AMD CPU + AMD GPU isn't any better of a fit than anything else, but it's your call to make.
CFx isn't really something I'd base a build around due to lack of support, but keeping your options open isn't a bad idea.

As for the PSU - it certainly should be.
65W TDP CPU that is unlikely to exceed 100W even if heavily overclocked (or as heavy as Ryzen can anyway)
Say 50-100W for the balance of the components.
Call it 200W for simplicities sake.

A Vega56 has been known to draw between 250-300W when overclocked, but does have power limitations.

The SeaSonic G650 is a great quality PSU. A little bit older of a platform vs their newer Focus+ etc, but very, very solid.
54A on the 12V rail = 648W where it matters. IIRC, in reviews, those guys could handle peaks of ~750W without issue - although I certainly wouldn't try to do that! :lol:

Ok thanks for the info. I think psu calc told me that even under full load my psu is 100w more than enough.
