[Igor'sLAB] undervolted and overclocked Vega 64

undervolted and overclocked in-depth look at Vega 64 by Alexander Brose

Sapphire RX Vega 64 Nitro with Bykski SP-VEGA64-X water cooler
Open Loop, 240mm + 360mm Alphacool Radiators, 5xNoctua P12 Redux @ 750 rpm

Software: Windows 10 1909 / Radeon software 19.12.2 / MSI Afterburner 4.5.0 + RTSS 7.1.0 and HWinfo 6.2
HBM Tweak Tool and Wattman or OverdriveNtool

Undervolting has two options: Either you save electricity (same performance as factory settings with lower consumption) or you gain performance (more clock with the same consumption as with the factory settings). If you combine both options and optimize the storage at the same time, you can already increase performance and reduce consumption at the same time. However, the decrease or increase in performance always balances to a certain extent with the decrease or increase in power consumption. Undervolting turns Vega into a significantly more efficient (or even faster) graphics card - but you cannot make it a “power-generating 1080 Ti killer” either - Alexander Brose

Undervolting by 100mV brings 2-7% more FPS and 0-10% less power consumption .
The Wattman power save mode costs 4-15% FPS, but brings 10-20% less power consumption.
Undervolting + overclocking brings 2-9% more FPS and 12-19% less power consumption .
Maximum overclocking brings 8-16% more FPS, but leads to 9-27% higher power consumption .
The "sweet spot" brings up to 5% more FPS and leads to 22-27% lower power consumption.

Chart done by 3Dcenter.org


In the end, the Radeon RX Vega 64 used is then quite flexible: it can be converted into a (relatively speaking) energy-saving graphics card, where roughly the default performance is + 55% higher energy efficiency (only calculated for the ASIC) . In this case, the ASIC with an average of 168 watts of power consumption is a whopping -90W below the default setting; based on the entire card, this should mean a power consumption of around 240 watts - 3Dcenter.org

Here's my RX Vega 64 LC undervolted years ago. With the same clocks I can get my Radeon VII down to 90w.

Thanks for posting that. My Fury was feeling a little slower after looking at Vega 64 uv + oc.
Now I want a VII instead. PCGH recently tested some newer games on VII.


Just joking I will end up collecting them all.

Someone needs to do a review of driver versions 19.6.3 or older compared to 19.7.1+ when running a Radeon VII. What ever AMD changed caused a massive decrease in power consumption.

Thanks for the heads up ... I myself got my vega 56 red dragon flashed to 64 and HS lapped, GC TIM and pads gave me higher performance than igors lab on air with 2700 to 3000rpm (max power consuption asic was 318w so far ) but my card is definitely not silent compared to his
I usually keep an eye on my card temp using wattman but the settings are applied with ODNT as usual ... Hbm oc is indeed the best to de for vega after undervolting which is king due to higher clocks reach the same hotspot and power target

Nice thread !


tomorrow if im not ****ting in my pants i will dismantle the cooler of my vega56 pulse!


Meanwhile this is my setting on AIR and used since 3 weeks.

Currently under testing ,sometimes i had issues with this setting but i think there was something wrong with my windows and or AMD2020 drivers.


@snipernote


Did you used paste and pads together on the gpu die and hbm ?
