[Comparison] Intel Core i7-1250U vs Intel Core i7-1255U – Does the extra wattage matter?

LaptopMedia.com Συγκρίσεις [Comparison] Intel Core i7-1250U vs Intel Core i7-1255U - Does the extra wattage matter?

Από: Severin Kolakov 09 Νοέμβριος 2022 / 07:00 0

The new 9W CPUs from Intel should be new champions of stability, offering reliable performance with stable clock speeds and wattages. Compared to the regular 15W Alder Lake CPUs, you might get less performance, but with fewer fluctuations.

Today we have two very similar chips, with 10 cores and 12 threads, but the wattage is different. However, once the CPUs get into benchmarks, all rules are off the table, as depending on cooling, wattage can increase and decrease, to suit temperatures and not allow the processors to overheat.

Today we are comparing the Intel Core i7-1250U against the Core i7-1255U.

Conclusion

The Core i7-1255U shows performance leads both when it comes to CPU and GPU tasks. In gaming tests, it also shows significantly higher FPS. However, the CPU is very laptop-dependent, as while we’ve seen well-performing devices with it, we’ve also seen models where the chip can’t break the 2500 mark inside Cinebench 20. All in all, if you’ll ever going to use a device with the Core i7-1250U, it’s going to be an enterprise model from a company, as enterprises are more likely to select it for their workforce.
