hello guys and welcome to another
tech fusion episode this is alex and today we're going to compare
the nominal hr 3090 right here to the lhr 3080 right here to see which
one is better for your mining needs the reason behind this video today is that i want
to show you guys exactly what happens with an rtx 3090 and if you should choose an rtx 3090
for the amount of money that you are going to insanely pay for them uh versus this lhr 3080
which uh let's face it frankly nowadays you can unlock its potential at around 74 to 75 percent
uh of its lhr uh just using some of the readily available software out there like nb miner or
t-rex miner uh we are going to test it uh with ethereum we're going to test it with ergo we're
going to test it with raven coin and we're going to test it with coin flux as well to see what you
can get out of this cards in terms of efficiency and mining hash rates we're not gonna cover
in today's topic dual mining but if you are interested to see uh what dual mining can do for
you with rtx 3080s the lhr versions then you can definitely check the video up here where i have
gone over and show you exactly how much money you can make with the locked lhr 30 series as well
at the end of the video don't forget to check out the spreadsheet where i put in all the data so you
can easily check and see for yourself what are the results this being said guys let's get on cracking
with the video and see exactly where we stand with both of these cards and see what efficiency we
can achieve okay guys so as you can see this is a short ethereum comparison between the non-lhr
version of the rtx 3090 and the lhr version of the rtx 3080 using the oc settings as you can see over
here on the left hand side we have the 30 90 doing 126 mega hashes a second for an efficiency rating
of 400 and a power draw of 300 and on the right hand side this being a lhr card of course we're
doing quite well i should say sitting at around 74 mega hashes a second with an efficiency rating
of 300 plus and a power draw of around 240 watts okay guys so now moving on to the next
cryptocurrency here we have the rtx 3090 on the left hand side which is doing it uh well it's
steadily hovering around 90 here as you can see and with an efficiency of 0.22 and a power draw of
around 400 watts which is quite more than i'm used to a mining ethereum and on the left-hand side we
have the limited hash rate 3080 which is steadily sitting at around 80.
Uh the 80 mark with a power
draw of 280 80 something 85 280 and an efficiency of 0.29 so draw your own conclusions here's i
do mention that the ocs for both of these cards are not really an issue both of them are running
at their stock speeds i've messed around with the power limits and the core clock and the memory
clock on both of them and i wasn't able to achieve any uh better gains i should say just tweaking
the core clock by increasing it and of course increasing the memory clock on this one i was
able to go as high as 96.98 and uh with this one i was able to go as high as around 85 so it's not
really a big performance increase by tweaking the settings around even though we're talking about
an lhr card over here and a non-lhr card over here all right so this being said let's
move on to the next cryptocurrency all right guys so moving on to the
next coin here we have ravencoin on the right hand side we have the 380 and
on the left hand side we have the 390 still if you just go ahead and disregard this r9 380 and
the 6700 xt as there are both cards that i have in the rig and i could not remove them for this
test but we are focusing on values here and the values will speak for themselves we have the r9 uh
correction d390 over here which is doing around 55 mega hashes a second with an efficiency of 140 and
drawing some 388 watts in the process and on the right hand side here we have the limited hash rate
once again the 380 uh which is doing a 44 mega hashes a second with around uh 300 watts of power
being drawn and an efficiency which is quite good of 141 compared to the 140 on the uh on on the
390.
Both of these cards are now running with stock settings so i haven't tweaked the settings
around uh just the fan speed has been increased on both of the cars to keep the temperatures
uh a little bit lower as you can see the 380 is running quite a bit hot with 98 degrees right
now on the memory temperature so i must increase the fan speed a little bit and it will generate
a little bit more noise but it is what it is so uh yeah this being said if you want to tweak the
settings around do keep in mind the draven coin um better takes or shows better results if
you adjust the core clock and by just i mean increase the core clock to a point where you are
stable enough or maybe you're happy enough with the temperatures that they are being generated
so uh yeah this being said let's uh carry on okay guys so now we're moving to the auto leicas
algorithm for the ergo coin here on the left hand side we have the rtx 3090 as you can see
it's sitting at around 150 mega hashes here and drawing some 220 watts and as you can see these
are the oc settings that i'm using on the rtx 3090 and on the right hand side here we are having
of course the limited hash rate rtx 3080 um which is sitting at around 200 mega hashes for
170 watts of power that is being drawn uh as in the previous case you have here the oc settings
for the msi afterburner so feel free to use these settings as a jump off point and uh try your own
settings or your own tweaks um to get your own uh own results maybe better than mine anyway
both of these are using the same t-rex version and these are the results that you are
getting for ergo on some of these cards thank you guys once again very much for watching
