Intel Core Ultra 5 338H & Arc B370 Benchmarks - Almost as fast as the Arc B390

Looking at the CPU performance, the new Core Ultra 5 338H performs well and is roughly on par with the new AMD Ryzen AI 9 465 at comparable TDP values (45/35W), which we reviewed in the Asus Zenbook S16. Intel is slightly ahead in the single-core tests, while the AMD chip offers better multi-core performance.

As expected, the Arc B370 is beaten by the Arc B390 in the synthetic benchmarks, but the power limits also play a role here and we will have a closer look at in the next section. The results of the Arc B370 are very promising in general and there is a big advantage over previous iGPUs from Intel (Arc Graphics 140V/140T) as well as AMD (Radeon 890M).

The first impression of the new Core Ultra 5 338H with the Arc B370 GPU is positive. The overall CPU performance (single and multi-core combined) is on par with the new AMD Ryzen AI 9 465 at similar TDP configurations. The Arc B370 continues the good impression of the Arc B390 and the overall difference is not that huge in the TDP range up to 35 Watt we were able to test so far. The performance delta will probably be a bit larger at higher power limits.

We will have to wait a bit longer for more comprehensive tests and we expect the first retail units with the new Core Ultra 5 338H and the Arc B370 within the next couple of weeks.
