The results are very entertaining.
We have repeatedly seen the capabilities of integrated graphics cores of Vega in the new AMD Ryzen 4000 mobile processors. But often these were comparisons in one benchmark.
Vega 7 and Vega 8 graphics cores against the GeForce MX250 and MX350. The battle for thrifty gamers
Now, a full review of two GPUs in a variety of games has appeared on the Web at once, and in comparison with the best super-budget discrete Nvidia adapters.
So, in the arena Vega 8 as part of the APU Ryzen 9 4900HS, Vega 7 as part of Ryzen 7 4800HS, Vega 7 as part of Ryzen 7 4700U, as well as Nvidia MX250 and MX350. That is, in this case, we can compare, firstly, the top AMD iGPUs in comparison with the most affordable discrete adapters on the market, and secondly, see how much the same GPU (Vega 7) differs in an energy-efficient and high-performance processor.
The source of a single table is not given, but we will figure it out like that. Let’s start by comparing Vega 8 and two versions of Vega 7. Vega 7 in a 45-watt Ryzen 7 4800HS is often 10-20% faster than Vega 7 in a 15-watt Ryzen 7 4700U, but it all depends on the game. Somewhere the difference does not even reach 5%, but somewhere it is almost twofold, but these are all rather exceptions. As for Vega 8 in Ryzen 9 4900HS, it is 5-10% faster than Vega 7 in Ryzen 7 4800HS, but sometimes the difference can be much larger. For example, in Middle Earth: Shadow of Mordor it is more than double.
Now let’s deal with discrete adapters. The GeForce MX250 performs on average at the Vega 7 level in the Ryzen 7 4700U. In some games, one adapter is faster, in some – another. At the same time, the MX350 is on average slightly faster than the top-end Vega 8, but in some games, it is inferior for some reason. In particular, in Red Dead Redemption 2 the difference is a huge 30% in favor of AMD.
