RX 480 Aftermath: Power Issue & Over-Hyping

2016-06-30
first off I want to say if you haven't yet seen my comprehensive rx4 80 review you can do so via the card right here my initial impressions of the card were very positive any game in 1080p could for the most part be maxed out while still maintaining appropriate frame rates and 1440p was a breeze as well if you were willing to compromise on enhancements such as anti-aliasing and for a whopping well not whopping at all actually 200 US dollars for the four gigabyte model and 240 dollars for the a key goodbye variant the arch 480 is no doubt one of the cheapest enthusiast grade cards available but not all was shiny on June 29th 2016 so many who were looking forward to the card ended up drifting into unknown territory making claims about a rx 40 that never held up in court some purported that the 480 was on par with the GTX 980 and yet others still asserted the 4 he would actually compete with the gtx 1070 these claims coming from people who had never owned the card and that's the point I want to address here I feel like AMD's been mistreated a bit so many of you over hyped this card and that's not necessarily your fault when I was under my non-disclosure of Y with AMD I couldn't I suppose correct those of you who were making those radical claims I wanted to so badly but my hands were tied and I feel like this swelled up into a giant bubble that became the expectation of the RX 480 and of course when I and other reviewers released our benchmarks of the card those expectations were inevitably not met so I invite those of you who were very adamant on rejecting a and B frayed another cycle due to this quote-unquote issue to reconsider nothing aimed he said about their own card was misleading even the floating-point performance of the card was on par with what we saw in the benchmark so I'm not even sure what was so surprising here another controversy involves the PCI power draw issue in a nutshell the card is pulling more power from the motherboards PCIe slot than it is from the six pin power connector now this isn't something that perpetually happens only during very minut peak demands for power does the card actually behave in this fashion the problem however is that the card can actually disable eyes the motherboard being used and cause it to shut off as a result of sucking too much power from that lane and I can actually attest to this firsthand believe it or not I was in the middle of building my $350 AMD PC build featuring this card right here actually and in the middle of every benchmark just about I think I think every game did this the computer turned off randomly no blue screen of death no warning just shut off now this is typically indicative of one of two things either the computer is not receiving enough power from the power supply or the computer is running too hot and shutting down immediately as failsafe mechanism well I was monitoring temps throughout the CPU never reached 50 degrees Celsius even during prime95 tests and the graphics card remained within its safe zone as well around ATC this led me to initially believe that my power supply wasn't cutting it the one that I was using that I undeniably obtained on the cheap is a 400 watt power supply that's that's it however this should have been enough I should have been enough for the computer I you know kind of did all the math in my head and it should have had about 50 to 75 watts of spare still pushing it in terms of how cheap the power supply was but it should have been enough but ok I decided to give the power supply the benefit of the doubt I swapped it for this 750 watt supernova from EVGA obviously no problems with this one right but still at the same point roughly in every benchmark the computer would continually turn off yeah and I'll admit I was a bit confused at first it never happened when I stressed the CPU but when I played games like rise of the Tomb Raider hit man dying like gta5 all of these resulted in system failure so while my 750 watt was still in the system I swapped the R X 480 with my gtx 980ti a car that consumes significantly more power about 350 Watts under full load and everything ran great actually I was even receiving great scores in my benchmarks stay tuned for that video by the way but now I was left in a bit of a deadlock I had already tested the arcs 40 for quite some time in my personal rig so there's no way this card is to blame and sure enough throwing the card back into my personal resulted in absolutely no problems whatsoever which brings us to the motherboard I was using an a 78 ax series a m2 motherboard for my athlon x4 635 the CPU in the AMD budget bill I didn't suspect the CPU because CPU issues don't typically result in total system blackouts just randomly rather those are usually accompanied by blue screens of death so the conclusion I came to then was that my motherboard was experiencing problems with power allocation it was being overloaded more than likely by the graphics card the arch 480 since the 90d TI didn't result in the shutdown and that was the only variable that changed in that scenario and sure enough after a quick search online boom the RX 480 power draw choose via the pci lane made sense and unfortunately it looks as though the motherboard I was using was just too I don't know I guess old is the word I suppose my z170 motherboard from a SUSE had zero problems with the RX for 80 but it honestly shouldn't it's new it wasn't cheap and it's power phase delivery system is top-notch so this is what it boils down to if you plan on purchasing a reference rx 480 or any rx 40 for that matter that features only a single 6 pin supplementary power connector don't pair it with a super cheap or super old motherboard the card will end up drawing more power from the PCI slot then from the 6 pin which can only deliver maximum 75 Watts by the way and will likely result in spontaneous system crashes during especially intense graphical scenes especially if your motherboard is not designed to send more than typically about 75 Watts through the PCI Lane what I suggest doing for my fellow viewers who aren't using bright and shiny new PC equipment and yet are still interested in the RX 480 is wait for third-party manufacturers to roll out their versions of the card in your case I recommend only purchasing a 480 with something greater than a 6 pin so something like an 8 pin or - 8 pin our X 480 these supplementary power connectors should in theory remove this power bottleneck from older motherboards giving you that smooth gameplay you always wanted but without the possibility of a system crash due to power instability so to wrap things up just remember that the our X 480 was never meant to compete with nvidia gtx 1070 or even its older maxwell based 980 it's price tag and specifications say so what the card intended to do was undercut a previous generation 9 70s and 3 90s with a great price point here in the states at least and rivaling performance expect future maturation of crimson drivers to boost those frame rates as well only by a little bit but hey that's how much the arts 40 lost the gtx 970 and a few of my benchmarks so it's anybody's game at this point if you like this video and the content that was brought up be sure to give this thing a thumbs up give it a thumbs out if you feel the complete opposite or if you hate everything about life click Subscribe if you haven't already stay tuned for a $350 AMD budget build feature in the RX 480 you want a PC on the cheap but you don't want to achieve graphics card stay tuned for this thing if it wasn't already in a card that was previously brought up in this video this is science studio thanks for learning with us oh and one more thing don't blame AMD or Nvidia for the extreme outrageous prices that you're seeing in Europe and Asia most of what you see in terms of price hikes with respect to what we pay here in the States has to do with import taxes tariffs shipping costs currency conversions et cetera so no neither Nvidia nor AMD hates you it's just business and unfortunately politics plays a huge role here till next time
