This is a repost from inside this thread: https://www.overclock.net/forum/67-a...rx-5700-a.html
The XFX ultra DD showed up yesterday and I have been messing around with it. It appears I have the first gen model with the stainless memory pads but besides that I got to say, it is really a nice card.
Even stock it is over 2x the performance of my old 580.
Benchmarks are all run with my 8700k at 4.9ghz.
RX 580 stock:
RX 5700 stock
Been playing with overclocking it, interestingly, while most said there was a hard limit of 1850mhz on the 5700 it allowed me to set 2000 with the stock bios. actually beating the stock XT bios numbers.
RX 5700 overclock maxed out
RX 5700 XT thic III bios flash stock
RX 5700 XT quick and dirty overclock 2050 core, 925mem, +50pwr
I then played around with morepowertool and gave it unlimited power limit and raised the core voltage to 1250mv to see what it could do. Was able to bump it up to 2100core and 975mem (can go 1000mem I later found but not sure about long term stability)
I plan to dial in an overclock over the next few days but wanted to see what my silicon lottery shook out to be first. Doesn't look like I can go much over 2100core, memory might be able to go higher but have not stress tested it yet.
The much more reasonable overclock was this, 2050 core, 1200mv, 1000mem +50prw. Next step is to try undervolting and see what the best bang for the buck settings are.
It generally sits around 230-240w during the XT bios 1250mv overclocking tests and the cooler handles it without an issue. Core sitting in the low 70's, hot spot about 20c hotter on average. Only complaint would be memory temps, they get hotter then I would like at ~10c above the core but still well below the 95c rating. A copper contact plate should fix that I would think but still acceptable. Noise level even at those power levels was perfectly acceptable as well, generally not going much over 2k rpm at 230w
For fun I launched kombustor donut test with the ~400w+ power limit and 1250mv going to the core (at the full 2100 core speed, it was stable even in this test). It was pulling almost 300W! The fan kicked up to like 80% but was still able to keep the card from throttling with hot spot around 100-105 and core at 80-85.As a rule the real core speed was about 50-60mhz lower then what I set, it seems like this is fairly normal for the 5700 series.
So yeah, like said above, this card got a lot of hate for nothing IMHO. The memory plate should of been copper or even aluminum and had better contact with the heat sink sure but the performance is still acceptable, memory never got above the 95c rating for gddr6, it just got closer then I would of liked. Think the highest I saw was around 90c or a bit higher during the donut test. Normally in the 80's.
Interestingly, I also get that fan bug with the XT bios flashed but NOT with the stock bios. About half the time the fans will not kick on until the card is 105c. Once they kick on though it works fine until I restart. If I manually turn them on it also works fine. The error is because with the fans off from boot it mistakenly reads the RPM signal as 65k rpm and thinks they are already going full bore. As soon as they spin it detects the real RPM and works fine. Not sure how to fix that.
Anyone know if there is a way to get the new copper plates for this card? I will be interesting to see if the B&H card has the copper plate, figure I will go ahead and order that one since it is cheaper then what I paid. They are supposed to get a fresh shipment of them from XFX on the 20th since they are out of stock now.
Did a few quick tests in game and the 5700 is legit over 2x the speed in real games as well vs the rx 580. The XT would be great but honestly at $100 extra it is not worth the cost to me, very happy with this decision. Now to hunt down a 1440p 144hz monitor...
Anyone else have some superposition benchmarks from 5700 or 5700 XT cards to compare? Curious how these match up.
