The slowest Arrow Lake processor was just benchmarked on PassMark, revealing its true single and multi-core prowess.
Core Ultra 3 205T Delivers 4% Higher Single-Core Than Core Ultra 5 225T, but Remains 10% Slower in the multi-threaded test in PassMark
The Arrow Lake lineup is vast, even though we see fewer SKUs in the market. Intel treats several SKUs as OEM units, which is why you won't see processors like Core Ultra 3 205T or Ultra 5 225T in the market. For the first time since the launch of the Intel Core Ultra 3 205T, we are now seeing the processor in action. Unlike the rest of the stack, the Ultra 3 205T appeared much later. As per the PassMark benchmark, the Ultra 3 205T was first seen this quarter, while the stronger Ultra 200T processors like Ultra 5 225T appeared in Q1 2025.
Nonetheless, we are seeing the Ultra 3 205T delivering a decent 4,432 points in a single-threaded test, which is roughly 4% higher than the Ultra 5 225T. Both SKUs have a different core configuration, with Ultra 5 225T bringing a 10-core configuration, while the Ultra 3 205T uses an 8-core config. So, you are seeing a lower score in the multi-threaded test. The Ultra 3 205T delivers 23,436 points vs 26,180 points by Ultra 5 225T. The gap is roughly 10%, which was expected, but keep in mind that the margin of error for the Ultra 3 205T is higher since only two samples have been registered till now.
PassMark scores tend to become more accurate as more samples are tested and registered on the platform. Still, the Ultra 3 205T is showing decent raw performance despite noticeably inferior specifications, including the cores, cache, and clocks. The Ultra 3 205 brings just 15 MB of L3 cache vs 20 MB on the Ultra 5 225T. It's also rated at the same 35W of TDP, making it a highly power-efficient chip for compact and ultra-lightweight devices.
While the PassMark benchmark page doesn't reveal the clocks, the individual benchmark pages reveal that the Ultra 3 205T could boost up to 4.68 GHz. It's also interesting to see that the improvement in scores is mostly due to the second benchmark, which delivered 25,949 points in the multi-threaded test, which is almost equivalent to the Ultra 5 225T's average score.
