Intel Pentium Gold 4415U vs Intel Core i5-7Y54
Intel Pentium Gold 4415U► remove
The Intel Pentium 4415U is an ULV (ultra low voltage) dual-core SoC based on the Kaby-Lake architecture and has been launched in the first quarter of 2017. The CPU can be found in ultrabooks as well as normal notebooks. In addition to two CPU cores with Hyper-Threading clocked at 2.3 GHz (no Turbo Boost), the chip also integrates an HD Graphics 610 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The SoC is manufactured using a 14 nm process with FinFET transistors.
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.
Compared to the more expensive Core i3-7100U, the 4415U offers a similar CPU performance (2.3 versus 2.4 GHz) and less level 3 cache but a slower integrated graphics card. Still, the CPU has sufficient power for office and multimedia purposes as well as somewhat more demanding applications.
The integrated graphics unit called HD Graphics 610 (similar to the HD Graphics 510) represents the "GT1" version of the Kaby Lake GPU (Intel Gen. 9). Its 12 Execution Units, also called EUs, are clocked at 300 - 950 MHz and offer a performance somewhat below the older HD Graphics 4400. Only a few games of 2015 can be played smoothly in lowest settings.
Specified at a TDP of 15 W (including CPU, GPU and memory controller), the CPU is best suited for small notebooks and ultrabooks (11-inches and above). Optionally, the TDP can be lowered to 10 watts (cTDP down), reducing both heat dissipation and performance and allowing even more compact designs.

The Intel Core i5-7Y54 is a very efficient dual-core SoC for tablets and passively cooled notebooks based on the Kaby Lake architecture and was announced in the end of August 2016. The CPU consists of two processor cores clocked at 1.2-3.2 GHz (2-core Turbo not specified yet). Thanks to Hyper Threading, the processor can execute up to four threads simultaneously. The chips also includes the Intel HD Graphics 615 GPU, a dual-channel memory controller (DDR3L/LPDDR3) as well as VP9 and H.265 video de- and encoder. It is still produced in a 14 nm process with FinFET transistors.
Intel basically used the familiar micro architecture from the Skylake generation, so the per-MHz performance is identical. Only the Speed-Shift technology for faster dynamic adjustments of the voltages and clocks was improved, and the matured 14 nm process now also enables much higher frequencies and better efficiency than before.
Despite the changed designation, the Core i5-7Y54 is the successor to the Core m5-6Y54 (Skylake Y-series), so the chip does not reach the performance level of other Core i processors due to the lower TDP. Thanks to its high Turbo clock, the 7Y54 can sometimes keep up with the 15 Watt models for short peak load and single-thread scenarios, but the clocks will drop significantly under sustained workloads. The CPU is still suitable for many more demanding applications as well as multitasking.
The integrated Intel HD Graphics 615 GPU has 24 Execution Units (EUs) like the old HD Graphics 515 and runs with clocks between 300 and 950 MHz in combination with this processor. The performance heavily depends on the TDP limit as well as the memory configuration; with fast LPDDR3-1866 RAM in dual-channel mode, the GPU should sometimes be able to compete with the HD Graphics 520, but can also be much slower in other scenarios. Modern games from 2016 will, if at all, only run smoothly in the lowest settings.
Contrary to Skylake, Kaby Lake now also supports hardware decoding for H.265/HEVC Main10 with a 10-bit color depth as well as Google's VP9 codec.
The chip is manufactured in an improved 14 nm process with FinFET transistors, so the power efficiency was once again improved significantly. The typical TDP for the Y-series is specified at 4.5 Watts, and can be adjusted in both directions depending on the usage scenario.
