Intel Core i5-7500T vs Intel Core i5-4460 vs Intel Core i7-7567U

Intel Core i5-7500T

The Intel Core i5-7500T is a power efficient desktop quad-core based on the Kaby Lake architecture. It was announced early 2017 and offers four cores and no HyperThreading (only 4 threads). The CPU clocks between 2.7 and 3.3 GHz. The integrated Intel HD Graphics 630 graphics card offers 24 EUs clocked at 350 to 1100 MHz. The TDP is specified at only 35 Watt and therefore even lower than mobile HQ quad cores (45 Watt). Thats why the CPU is also used in some laptops.

Intel Core i5-4460

The Intel Core i5-4460 is a mid range desktop quad-core processor based on the Haswell architecture. It was introduced in Q2 2014 and is manufactured in 22 nm. The processor does not feature Hyperthreading, and therefore can use only 4 threads with the 4 cores.

The performance is on average somewhere between an older Core i5-4430 (similar but lower clocked) and a new Skylake Core i5-6600T. Compared to mobile processors, the performance is similar to a Core i5-6300HQ. Therefore, the performance should be sufficient for all daily tasks and games.

The CPU also integrates a Intel HD Graphics 4600 called graphics card clocked at 350 to 1100 MHz.

Intel Core i7-7567U

The Intel Core i7-7567U is a fast dual-core SoC for notebooks based on the Kaby Lake architecture and was announced in January 2017. The CPU has two processor cores clocked at 3.5-4 GHz (two cores up to 3.9 GHz). The processor can execute up to four threads simultaneously thanks to Hyper Threading. It is also equipped with an Intel Iris Plus Graphics 650 GPU with 64 MB eDRAM, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still manufactured in a 14nm process with FinFET transistors.

Compared to the Core i7-7560, the 7567U has a higher TDP of 28 vs. 15 Watts as well as higher clocks.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

Thanks to the high clocks pf up to 4 GHz and 64 MB eDRAM (can also be used as L4 cache by the CPU), the Core i7-7567U is the fastest dual-core for notebooks in the beginning of 2017. It competes with lower clocked quad-core models and can convince by the excellent single-thread performance. Some games might require a real quad-core though and could not run perfectly on the dual-core, despite Hyper Threading.

Graphics

The integrated Intel Iris Plus 650 Graphics is the GT3e model of the Kaby Lake GPU (Intel Gen. 9.5). It has 48 Execution Units running at 300-1100 MHz and the performance is comparable to a GeForce 920MX thanks to fast eDRAM cache. However, there aren't any significant improvements compared to the old Iris Pro 550, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.

Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel specifies the TDP with 28 Watts, which can be reduced to 23 Watts (cTDP Down) depending on the usage scenario. The TDP is pretty high compared to the common 15-Watt TDP for dual-core processors, but allows a better utilization of CPU and GPU Turbo.
