[HWBot] Elmor Pushes AMD RX 480 to 1.7GHz on LN2 - Page 2

Power consumption at those voltages is going to be something like this...


Dang...

I mistook that for a 970 power draw graph once you mod the bios to get rid of Nvidia's power saving features. wink.gif

According to Hwbot and xDevs.com , GTX 1080 hard limit :  1.25V , Now this one reached 1.5V ! scared.

Obviously the caveat here is that after 12-22 months of optimization, those scores are likely higher now than when they were first reviewed.

Still, I think it's useful to know that an RX 480 @ 1700 core and no memory OC is on par with a (near) max OC 980. If AIB 480s can OC to 1500/8800 or whereabouts, they'll probably end up roughly equal to a stock 980 G1 in performance.

Btw nothing went wrong, the 1.65 GHz scored higher because of "tweaked drivers", so like I said, it's not a directly comparable score and doesn't really yield any useful info.

Maybe the "extreme" models. The voltage\power draw is probably too high when efficiency is supposed to be a selling point with Polaris.

Even if they only ship with like a 1350-1400 core clock speed, game performance is solid for the price. These benchmarks kind of just ruin the real purpose of all these cards which is gaming and performance is way closer between products when you factor in CPU\memory and other bottlenecks since a majority of PC gamers are not running top end CPUs, even if they own a 1080.

Someone running a 480 at 1080P and another at 1440P with a 1070 will probably get similar gaming performance at similar settings with the only difference being a higher resolution, which most people must not care about.

Seems impossible on this board to have a discussion on Hardware without a few popping in and "making fun" of a specific product for whatever reason(seriously, why bother).

How about this fellow on OCN with 15k graphics score at only 1350/2200 MHz?

Overclock the core to 1700MHz and ignore the memory is a bad idea, especially with a 256 bit card.

Do you people realize that under extremely cold temps the resistance of silicon drops and this is the reason for using ln2 for overclocking.
Even at 1.5v the card might only consume 250w if temps are below -100C, so there is no point in measuring it

There's not point in measuring it at all..

Who plays with LN2. It's just another benchmark. #makeNvidiagreatagain

Probably the memory isnt stable with OC and such high gpu OC? or the voltage required for GPU was also ties to mem like hawaii?

Theres something wrong with their ln2 bench result, im wondering if the voltage scaling bug with fiji might be an issue. Der8auer scored 15.4k a 1500/2250 with no tess mods, and score 16.7k at 1480/2250 with tess mods; something is wrong with this result.

At 1700/2250 we should see scores pushing 17k for graphics without tess mods considering ~.95 scaling most amd cards exhibit when oc'd in synthetics.
