The first custom designed based on Vega architecture has been tested.
ASUS STRIX Vega 64 also uses Vega XTX
We finally a first look at custom Vega. Two samples were provided to ComputerBase, Hexus and Hardware.Info. The card is clocked at the same frequency as Limited Edition of Vega 64, which is 1247 MHz (base frequency) and 1630 MHz in boost (according to Hexus).
Same as reference design, the STRIX has two 8-pin power connectors, but slightly modified power delivery. The maximum power limit is 260W for GPU (compared to 240W for reference design). This ‘feature’ alone increases the clock speed for the card during tests.
Performance wise we are looking at slightly worse experience than fully overclocked reference RX Vega 64 (Max).
Tests conducted by Hardware.Info give STRIX a few percent improvement over reference design. This performance upgrade comes at the cost of 9.1% higher power consumption.
Thanks to the more efficient triple-fan cooling solution, the STRIX RX Vega 64 has more headroom for additional power. It helps to reduce the frequency oscillation, but the temperature is not really much different from the reference design.
At Hexus we have a quick comparison between ASUS and AMD Vega 64 in number of gamers plus these two chart showing 44W higher power consumption of the whole system:
Neither publication took pictures of the PCB, which suggests we are only looking at carefully conducted previews under the eyes of ASUS employees rather than full reviews.
