G4 900MHz Game Requirement Analysis
Intel Iris Plus Graphics G4 900MHz are integrated graphics in some of Intel's Ice Lake mobile processors. It can be found in Intel Core i3-1000NG4 & Intel Core i3-1000G4
The Ice Lake architecture succeeds the Kaby lake architecture and aims for increased CPU and graphics performance.
These Gen 11 graphics solutions include the new Variable Rate Shading (VRS) support. This lets shading time for object shading in game to be allocated more accurately by the game's developers. So for example, a graphics depicting an object that cannot easily be seen can be marked as not needing such high performance and visual accuracy and thus save processing power. GPU
The central unit initially runs at 300MHz and goes up to 900MHz, in turbo mode.
Because Performance depends heavily on the Memory Bandwidth, it may vary from System to System.
Best case scenario, expect Intel Iris Plus Graphics G4 900MHz performance to be similar to the AMD Radeon RX Vega 8 GPU.
