The Arc B390 has 20% more cores (12 vs 10) and is 21% faster (call it basically 20% -- nice linear scaling, btw). Not sure I'd call it "Almost as fast", because then one could also say that the RTX 4050 Laptop is almost as fast as the RTX 4060 Laptop, but it's a tier above (20% faster). I'd define a 10% difference as "almost as fast". Find a different term. Still good performance tho, thanks of the linear scaling, which also could mean that a, say, 16 Xe cores Arc iGPU could be 33% faster than the Arc B390, if it had the bandwidth, that is (LPDDR5X-9600 -> LPDDR5X-12800 would be required).
Handhelds and ultralights have a new king! Truly epic efficiency here. Performance per watt is truly off the charts for x86. The news just keeps getting worse for AMD...
We had the chance to test the performance of the new Intel Core Ultra 5 338H including the Arc B370 GPU with 10 Xe cores in some benchmarks. The results are very promising and the performance difference to the Arc B390 is small.
