It isn't much, but I don't believe it to be insignificant, when you're riding right on that 60 FPS line. Sometimes that extra 3-5% will help.

It's better to save up on a freesync monitor.

whats your opinion on the XFX RX 480 RS 8GB ,MSI RX 480 Gaming X 4GB, Sapphire RX 480 4GB Nitro+ for overclocking and better performance overall?

Well...since I hadn't wrapped up his card yet...thought I would do one more round of testing.

First, here is the spreadsheet I've been keeping of all the drivers:

Driver Benchmarks Red Devil RX470 16.8.2-16.11.4(Added 16.11.3 and 16.11.4)

I've been following this thread since I got the card. I saw where some were talking about cards that are "future-proof". So I decided to do some testing. I don't have access to a lot of programs/games that use DX12. I have Time Spy, and BF1 does support DX12.

Here is how I went about testing.....

The GTX970 bios is really easy to mod. So I modded it to 1270 on the core and 3500 on the Vram. I also lowered the voltage to match the RX470(1.150v). I'm not here to show off, or put either mfg. down. I just wanted to see what each card did, clock for clock. The CPU is @4.0ghz for all testing. I think both mfgs. have their own niche in the market. I wouldn't and don't second guess anyone's purchase.

First I ran BF1 in DX11 and DX12 on both cards. I used Fraps to capture all the data. Even though the OSD doesn't show up in DX12, the benchmark utility does work. I set it to capture 5 minutes of gameplay. I used a live game, and not the campaign.

DX11 GTX970 Frame Times Warning: Spoiler! (Click to show)

DX11 RX470 FPS Warning: Spoiler! (Click to show)

DX11 GTX970 FPS Warning: Spoiler! (Click to show)

DX12 GTX970 Frame Times Warning: Spoiler! (Click to show)

DX12 RX470 FPS Warning: Spoiler! (Click to show)

DX12 GTX970 FPS Warning: Spoiler! (Click to show)

I think I have these labeled right.....I kinda lost my mind trying to put the notes in to reflect the runs. biggrin.gif

OK...on to Time Spy. Same settings. I made one run with each card at 1270/7000. I then flashed the original bios back on the GTX970.
Warning: Spoiler! (Click to show)

http://www.3dmark.com/compare/spy/760994/spy/760821/spy/759689#

Just a couple of notes on the runs with the GTX970. The first run even though it shows 1114 on the core, that is incorrect because of the boost. It was actually 1342/7008. The second run, the card didn't have enough voltage to hit the boost of 1270. I didn't raise the voltage, I just added +55 to the core. I kinda messed up in the notes section.

So...clock for clock....especially in DX12 the RX470 beats it, hands down. Even on the stock bios of the GTX970, the RX470 beats it in Time Spy. While I'm not 100% sure of what my FPS in BF1 in DX11 on the GTX970 is. I believe that it would beat it there too, but don't quote me on it. I think I posted some of the Fraps results in the BF1 discussion thread, I'm not sure(those would be at 1506/8000).

Final thoughts:

For a card that is on average about 125.00/150.00 less that than what the 970 launched at, it's a helluva card! While the temps are a tad higher(I think the highest I saw all day was 71° in BF1:67° Vram), AMD cards seem to be fine. The RX470 uses less wattage than the 970 as well.

Personally, I wouldn't run either card at 1440p. That's just my preference. I've tried both, and if you are on a 60hz monitor that may be fine. Just not my cup of tea. A lot of people fixate on the FPS, but frame times are just as important. Again, just my opinion.

If the developers implement DX12 correctly, then I would say AMD has the upper hand.

EDIT: Here is the link in the BF1 thread.

http://www.overclock.net/t/1598780/official-battlefield-1-information-and-discussion-thread/3390#post_25662773

EDIT II: I don't want to mislead anyone, but these were all on custom settings. There are screen shots showing the settings for BF1. Time Spy were all at the default. thumb.gif

Nice! thumb.gif

I think my high scores are in my sig....I don't think I've beat them lately. I really have tried in a while. Seems nVidia's drivers have fallen off for me.

Hey guys I need some help. I just got a Rx 480 and a 144hz 1440p freesync monitor. Problem is when I set the refresh rate to 144hz the monitor just flickers in games. I thought the card was bad so I RMAd it but the problem persists on my new card. I also tried the monitor with a GTX 780 and 144hz works fine. Anyone have any ideas? Is freesync 144hz working for you guys? Any help is appreciated, I just joined team red and want this to work.

Ive tried the latest drivers and have windows 10.

Got the urge to fiddle my card last night and thought I'd replace TIM and all the pads on my Nitro+OC. Decided to use MX-4 and Arctic thermal pads. Ran 5 loops of Valley and took the max. temp. Temperature difference, after normalizing for intake temperature, was 1C. 62C vs 61C Basically within margin of error. On one hand it's kind of underwhelming that you can't use cheap TIM to get a bit better temps, on the other it's nice that Sapphire uses stuff that's "good enough". It's either that or the bottleneck is somewhere else. Next up - seeing if the fans on the card suck or blow. I should get my hands on a few Arctic F9 fans in a couple of days (hopefully before weekend) and while I'm sure they'll be much better noise-wise I'd like to see how it will affect temperatures.

then do you think is worth spending a bit more for a R9 Fury over a 480?

I think buying a Fury right before the announcement of the next top the line GPU is not a good decision.
