3. Desktop Scenario

3.1 BareMetal Comparison(WX5100)

Conclusion:

1. WX5100 behaves almost the same on both i5/i7 platforms.
2. i5’s cpu power won’t be a bottleneck in WX5100 scenario.

3.2 BareMetal Comparison(5700xt)

Conclusion:

1. 5700xt runs smoother in i7 than on i5, perhaps i5 4th is too old for working together with 5700xt?(4 cores, bus width, etc).
2. i5’s CPU/Memory becomes a bottleneck in 5700xt testing.

3.3 Virgl On i5-4460(WX5100)

Conclusion:

1. glmark2: Virgl is 31.3% of the baremetal performance.
2. Unigine Valley/Unigine Heaven: Virgl performance almost the same as baremetal.

3.4 Virgl On i7-9700K(WX5100)

Conclusion:

1. glmark2: Virgl is 44.2% of the baremetal performance.
2. Unigine Valley/Unigine Heaven: Virgl performance almost the same as baremetal.
3. Comparing to 3.3: glmark2 will be improved using powerful CPU/Memory.

3.5 Virgl On i5-4460(5700xt)

Conclusion:

1. glmark2: Virgl is 21% of the baremetal performance.
2. Unigine Valley/Unigine Heaven: Virgl is around 55%~60% of the baremetal performance, while in 4k behavior, 87% of the baremetal performance.

3.6 Virgl On i7-9700K(5700xt)

Conclusion:

1. glmark2: Virgl is 19% of the baremetal performance.
2. Unigine Valley/Unigine Heaven: Virgl is around 55%~60% of the baremetal performance, while in 4k behavior, 83% of the baremetal performance.

4. Android Scenario

Conclusion:

1. Ludashi’s top score: around 61W, the maximum performance would be 1080p?
2. scrcpy will greatly impact the performance when using Virgl under low-end CPU.
3. virgl will be 85% for the best of bare metal on WX5100 on i7, 91% of bare metal on 5700xt on i7
