Intel Core i5-8250U vs Intel Core i3-1005G1

Core i5-8250U vs Core i3-1005G1 specs and performance

According to the hardwareDB Benchmark tool, the Core i5-8250U is faster than the Core i3-1005G1. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-1005G1 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-8250U has significantly more cores with 4 cores compared to the Core i3-1005G1 that has 2 cores. It also has more threads than the Core i3-1005G1. Our comparison shows that the Core i5-8250U has a slightly higher clock speed compared to the Core i3-1005G1. Furthermore, both these CPUs have identical turbo speeds. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i5-8250U has significantly more L2 cache than the Core i3-1005G1. The Core i5-8250U also has significantly more L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i5-8250U has more threads than cores. Each physical core is split into multiple threads.
