ASUS ROG STRIX RX Vega 56 O8G GAMING Review

We have our first custom retail AMD Radeon RX Vega 56 GPU video card on the test bench in the form of the ASUS ROG STRIX RX Vega 56 O8G GAMING video card. ASUS has created a robust ROG STRIX version of RX Vega 56 with a factory overclock and overclocking ability. Let’s see what it can do.

ASUS ROG STRIX RX Vega 56 O8G GAMING - GPU Clock

Keep in mind that the base clock on the ASUS ROG STRIX Vega 56 O8G GAMING is 1297MHz, so that is where we are putting our red line. The GPU boost clock is 1573MHz, so that is where we are putting the green line. Remember also that with AMD’s clock you do not always achieve or exceed the boost clock. The actual frequency should not however drop below the base clock.

In the above graph we have the ASUS ROG STRIX RX Vega 56 video card. You can see that the minimum is 1447MHz and the maximum is 1518MHz. The average of the clock speed is 1480MHz. The clock speed is well above the base clock but does not exceed the boost clock. It also varies.

To put some perspective on the clock speed of the ASUS STRIX video card we have re-run this with the latest GPUz on the AMD Radeon RX Vega 56 reference video card from AMD. In the graph above is our reference card.

You can see the minimum is 1340MHz and the maximum 1456MHz with an average of 1392MHz. Therefore, the ASUS ROG STRIX RX Vega 56 is running (on average) 88MHz or 6% faster via clock speed alone. The maximum clock speed has a difference of 62MHz and the minimum has a difference of 107MHz.

This shows that the ASUS ROG STRIX RX Vega 56 is indeed running faster with its factory overclock compared to the reference card.


Temperature over Time

Now it is time to compare temperatures. The ASUS ROG STRIX RX Vega 56 is shown above. You will note it does hit 80c at maximum and 73c on average. This is at default settings, no overclock. There is a reason for this. Simply put the ASUS ROG STRIX RX Vega 56 runs at a higher clock speed than the reference card, and at a higher GPU voltage. Let’s look at the reference RX Vega 56 temps first.

You will see the reference card hits 76c, cooler than the ASUS’s 80c. The reason for this is as we started to discuss above, the clock speeds are running higher on the ASUS card, and the GPU voltage is higher as well. We found that the VDDC on the reference Radeon RX Vega 56 is 1.1687V. However, on the ASUS ROG STRIX RX Vega 56 the VDDC is 1.1938V.

In addition, the fan profiles are different and the fans operate at different speeds with different forces of air. To lower the GPU temp on the ASUS card all one must do is increase the fan speed a bit by using a custom fan profile. Though the GPU runs warmer, it is more stable thanks to the increased voltage on the ASUS card.
