Intel Core i3-7100U vs Intel Core i3-6100T

The Intel Core i3-6100T is based on the 6th generation Skylake S-architecture and is intended for energy-efficient desktop systems such as compact PCs or Home Theater PCs.

The Intel Core i3-7100U, on the other hand, is part of the 7th generation Kaby Lake U-architecture and was primarily developed for mobile devices such as Ultrabooks and thin laptops, where low power consumption and long battery life are paramount.

Both processors are manufactured by Intel using the 14nm fabrication process and feature two physical cores and four threads thanks to Intel Hyper-Threading. This enables efficient processing of multiple tasks. The Intel Core i3-6100T achieves a maximum memory bandwidth of 34 GB/s, while the Intel Core i3-7100U is at 30 GB/s.

Both have a 3 MB Level 3 cache. PCIe is not mentioned for the mobile Intel Core i3-7100U. In a performance comparison, the Intel Core i3-6100T shows significantly higher single-core and multi-core performance than the Intel Core i3-7100U. The performance differences, each exceeding 10 percent, are due to the higher clock frequency and the design of the Intel Core i3-6100T for more robust computing power in the desktop segment.

Neither processor is optimally suited for gaming. The Intel Core i3-6100T with its integrated Intel HD Graphics 530 offers marginally better performance for very simple or older titles than the Intel Core i3-7100U with Intel HD Graphics 620, supported by the slightly higher memory bandwidth. The Intel Core i3-7100U is characterized by a significantly lower Thermal Design Power (TDP) and thus lower power consumption, making it ideal for battery-powered devices and fanless systems.

While the Intel Core i3-6100T is energy-efficient for a desktop processor, it requires more power than its mobile counterpart. On the used market, both older processors are available at low prices. The Intel Core i3-6100T offers higher computing performance per currency unit, while the Intel Core i3-7100U provides a better price-performance ratio in terms of energy efficiency and mobile integration.

In summary, the Intel Core i3-6100T is the better choice for compact desktop PCs that require solid computing power for everyday tasks. The Intel Core i3-7100U is optimal for mobile devices where battery life and low heat generation are crucial, ideal for productivity and web applications on the go.
