AMD is struggling with the launch of Radeon RX Vega, but it won't help that custom RX Vega cards are suffering from WORSE performance than the reference cards... something that is now being tested.
The new ASUS STRIX RX Vega 64 has been sampled out to a few reviewers so far, with the sites testing the new STRIX card. ASUS' latest Radeon graphics card has a 260W TDP, which is massive - even compared to the already large 240W+ on the reference card. This increased TDP allows for higher clock speeds than the reference card, but does it result in more performance? Nope. Actually, less performance.
At stock frequencies, the Radeon RX Vega 64 reference card loses to the ASUS STRIX RX Vega 64, but when RX Vega 64 reference card is overclocked to its maximum clocks, it BEATS the overclocked and custom ASUS STRIX Vega 64 card.
