You may be right. I'll do some fiddling tomorrow and see what happens. Going to change the TIM and apply some Gelid Extreme and see what that does. Also, I may try and rig a Asus CU fan and heatsink on it as long as the vram is cooled as well.

I used to do a lot of sub-zero oc.

If it is like the previous GloFo nodes then it will clock up with really low temperatures until you hit the GCN wall.

In general GloFo and high temps means a lot of leakage and bad efficiency.

I bet the sweet spot is around 60C for core and vrm but we will see

I'm going to do a run with max fan speed and see what happens. I think I can stand the turbine engine for 1 run.

http://www.3dmark.com/3dm/12832280? - Gained a little. 13821 this time. Temps never got above 64c - Maybe this thing will benefit some from some proper cooling. I'm excited to see what the AIB models can do.

Can you please restate your detailed wattman settings? Different state voltage, clock, powertarget? On which you got 13.7k score please

On that particular run it was set up as follows;
frequency - 1.5%
gpu voltage - 803 - 816 - 941 - 1003 - 1053 - 1110 - 1135
Memory - 2050
Memory voltage - auto
Fan speed control - 2600/3900
Temperature targets - 80 max/60 target

My most recent run; http://www.3dmark.com/3dm/12833441 - gfx score 13930 was as follows;
frequency - 2.0%
gpu voltage - 818 - 831 - 956 - 1018 - 1125 - 1150
Memory - 2100
Memory Voltage - 990
Fan speed control - 2600/4100
Temperature targets - 80 max/60 target

Here's a comparison of my gains from my first initial test (stock) to my most recent (above)

I'm surprised you didn't lose some faith in Nvidia for lying about all the specs on the 970. They only came clean when all the evidence was compounding against them.
yeah it was overheating. They should have learned from that and make a better cooler but they have chosen to fail again.

RX 480 will stay at 240$ for months, GTX 970 will stay at this point for maybe 5 weeks tops.

Here is the cheapest GTX 970 I managed to find: https://www.amazon.com/Asus-TURBO-GTX970-OC-4GD5-ASUS-Graphics-Cards/dp/B00WJOU7DA for 260$
Bottom tier crappy cooler, that's probably about the same as the RX 480 reference cooler in performance.

RX 480 has :
4.5 more GB of VRAM
Faster VRAM
Months of driver improvements ahead of it (while the 970 will be abandoned soon)
Same or higher performance
Improved frametimes
Aging heuristics, so the card will last longer
Superior geometry performance
Console optimizations directly translate
Async Compute
Support for HDR displays
Variable rate shading for VR
Better video code/decoding

And a lot more I probably missed



GTX 970 is outdated technology, nobody should buy it at anything more than 180$ at this point.
All these "missing stuff" is marketing crap... Nothing else. 90% of ppl wont even know whats that for .. rolleyes.gif

More ram? you wont need more ram if you cant turn the settings to ultra/run high resolutions because the card is not powerfull enough. This is 1080p card and in this resolution you wont pass 4GB... rolleyes.gif mark.

If they are still selling 970 for 2-5 weeks, thats fine. I dont see a reason not to buy it if its for the same price, NEW.
970 new is even cheaper than this 8GB 480...
MSI 970 - 210£ https://www.overclockers.co.uk/msi-geforce-gtx-970-oc-reference-fan-4096mb-gddr5-pci-express-graphics-card-gx-279-ms.html
Powercolor 480 8GB - 219£ https://www.overclockers.co.uk/powercolor-radeon-rx-480-8192mb-gddr5-pci-express-graphics-card-gx-187-pc.html
I just lol....Both new cards.
Or you can have this asus strix for 229£ with 20£ cashback so 209£ -https://www.overclockers.co.uk/asus-geforce-gtx-970-directcu-ii-oc-strix-4096mb-gddr5-pci-express-graphics-card-20-pounds-cashback-gx-352-as.html

Granted you provide some good points, you are comparing cards that are aimed for different performances, and ulitmately pricing. You compare these cards at new rx 480 vs used gtx 970. Just because the 970 is older doesn't mean everyone is striving to buy used. So you are comparing a 200-240 dollar card to a 350 dollar card, in perspective. And lets not forget the 970's "4gb" memory which IMO is the main factor that ruins the 970.

The rx 480 is aimed much more at direct x 12 performance, which tests show the 970 quickly loses steam. The 8gb of memory may be overkill but it is much faster than the 970's.

As for overclocking you also compare a reference rx 480 vs clock speeds of aftermarket cards. Seeing that someone mounted a cpu cooler only and brought it up to 1.4+ ghz is amazing. I can only imagine what other brands will do, especially if they create their own pcb and upgraded components. And then these cards will likely be around 300 bucks. still cheaper than a new 970.

I am not a fanboy either. Actually I am an nvidia owner myself. I have a bios flashed msi gtx 970 gaming. And I really do love the card, but the main factor that drives me insane is the memory.

I think you are just early to jump the gun. I will sit back and wait for the show to finish first before I make my conclusion.
Well as I mentioned above, the main important thing is ...the PRICE NOW. Now 970 costs the same(even cheaper) as 480....and im talking about a NEW card. See above.
..and 4GB for 1080p is nto an issue at all.

Also....power consumption of RX480 is the same as GTX 1080 while GTX 1080 delivers +100% more performance...LOL LOL LOL. This 480 is super power efficient ? Wake up and look at 1080/1070.


Cmon fanboys, stop being defensive. This card is not what they promised us...

Well. Some games may take advantage of 4+gb. And must if you tend to go multigpu later

Can you do this type comparison with extreme /ultra mode please.
post #280 of 991
Neither of these were run with my newest settings. I haven't ran ultra or extreme yet, currently downloading gtav and bf4 so I can do some in game benchmarking. The better scores were ran at 1350/2050 with 50% power level. Not sure why it says they were default. Must be a 3dmark issue.

http://www.3dmark.com/compare/fs/9047410/fs/9054623 - ultra

http://www.3dmark.com/compare/fs/9053170/fs/9047326 - extreme
