With some further optimization, it seems Intel may soon be able to close the gap between its integrated graphics and those found on AMD's APUs. WCCF Tech offers some analysis over here.
The Tiger Lake-U's integrated variant is however around 18% slower than the Ryzen 7 4700U. But at the same time, both the discrete and integrated variant features 96 EUs, but the desktop GPUs tend to offer higher sustainable clocks compared to integrated chips. Still, Tiger Lake CPUs and DG1 discrete GPUs are being handled by two different teams at Intel and it is possible that Tiger Lake integrated GPUs may not be as well optimized as the discrete DG1 graphics board right now.
