The RX 580 Pulse ships with a small factory overclock but I struggled to get much more out of it. In the end, I settled on 1380MHz, which is a mere +14MHz to the core. Anything further resulted in hard lockups in Fire Strike. This works out as a mere 1% frequency boost.
In Fire Strike, this overclock led to a very small bump to the graphics score, with our OC bringing a 2.8% score improvement.
It is also worth noting that I did not overclock the memory, as I was having a hard enough time trying to get stability just from adding +20MHz to the GPU core.
Good review as always! ;D
Great review thank you. So this card is most likely using up Sapphires remaining 480 chips hence the poor OC the card got or you just got a card that lost the chip lottery. lol
My nitro 480 is rock stable @1415/2050. So probably bad sample or issue is somewhere else.
It’s just the silicon lottery – we can rule out Sapphire re-using a 480 as the 580 is manufacturered with a modified 14nm process so the chips aren’t exactly the same. But it is still the same, overall Polaris architecture.
Yea probably just a bad sample Sapphire is a good company I own 2 TrI-X cards and they have been very solid cards and the Tri-X coolers used on their cards are very well built for sure.
Yep most likely 100% true just the Silicon Lottery and nothing else.
In a nutshell, its about as fast as a overclocked GTX980, pretty decent. Don’t forget folks that RX480/580 actually tends to OC better with lower voltages. The reasoning for not attempting a memory OC is pretty weak though, memory OCing on graphics cards is very easy and not time consuming.
You mention a £239.99 retail price but when I follow your link the card is £449.99 so almost twice this price : any thoughts on that inflation in less than a year ?
