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.
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
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.
Graphics
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.
Power Consumption
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 AMD A6-9225 is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2018. Compared to the one year older A4-9220, the A4-9225 has a 200 MHz higher CPU Boost clock but a slower iGPU. It integrates two CPU cores (one Excavator module with 2 integer and one FP unit) clocked at 2.6 GHz to 3.1 GHz. It also includes a Radeon R4 GPU, probably with 192 shaders at up to 686 MHz, as well as a single-channel DDR4-2133 memory controller, H.265 video decoder and chipset with all I/O ports.
Architecture
Stoney Ridge is the successor to the Carrizo architecture and the design is almost identical. Thanks to optimized manufacturing processes and more aggressive Boost behavior, however, the clocks are a bit higher at the same power consumption. The memory controller now also supports DDR4-RAM, in this case up to 2133 MHz. Stoney Ridge is the designation for the smaller dual-core and single-core chip, while Bristol Ridge is the bigger quad-core chip with dual-channel memory controller. More technical details are available in the following articles:
The average 9225 in our database proves to be a very, very, very slow processor, its multi-thread benchmark scores only just matching those of the Core 2 Duo P8600 (a dual-core CPU that saw the light of day in 2008). This is a record-breakingly poor performance and a warning to anyone looking to purchase a system built around this specific A6 series CPU.
Graphics
The integrated Radeon R4 (Stoney Ridge) GPU is probably similar to the R5 with 192 active shader units (3 compute cores), but a reduced clock of just 686 MHz instead of 800 MHz. More details about the GPU are available in the linked articles above.
Power consumption
This AMD A6 series chip has a default TDP (also known as the long-term power limit) of 15 W. Laptop makers are allowed to reduce that value somewhat, 10 W being the lower limit, with clock speeds and performance changing accordingly as a result. By going for the lowest value, it will be possible to build a passively cooled system around the APU.
Last but not the least, the A6-9225 is built with a 28 nm process leading to very, very low energy efficiency, as of 2022.
