Intel Pentium Gold 4415U vs Intel Celeron J4005 vs Intel Core i7-7700T

Intel Pentium Gold 4415U

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.

Intel Celeron J4005

The Intel Celeron J4005 is a dual-core desktop SoC primarily for mini PCs and mini ITX mainboards. It runs at 2 - 2.7 GHz (Single Core Burst) and is based on the Gemini Lake platform. Similar to the Apollo Lake predecessor, the chip is manufactured in a 14 nm process with FinFETs but offers slightly improved processor cores, double the amount of L2 cache, a smaller package, a new generation of monitor outputs (Gen 10) and a partly integrated WiFi chip. Besides four CPU cores, the chip also includes a DirectX 12 capable GPU as well as a DDR4/LPDDR4 memory controller (dual-channel, up to 2400 MHz). The SoC is not replaceable as it is permanently soldered to the mainboard.

Architecture

The processor architecture was slightly reworked and is now called Goldmont Plus. It features an increased level 2 cache (to 4 MB). That means the per-clock-performance should be a bit better, but not anywhere near the Core CPUs like Kaby Lake Y.

Performance

The average J4005 in our database is in the same league as the Celeron N3450 and the Celeron 3865U, as far as multi-thread benchmark scores are concerned. This is an abysmally poor result, as of early 2023.

Power consumption

This Celeron series chip has a default TDP, also known as the long-term power limit, of 10 W. That's not much at all and thus good enough for passively cooled tablets, laptops and mini-PCs.

The J4005 is built with one of Intel's old 14 nm processes for poor, as of early 2023, energy efficiency.

Intel Core i7-7700T

The Intel Core i7-7700T is a fast quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the 35 Watt models and significantly slower than the similar named Core i7-7700K. The four Skylake based CPU cores are clocked from 2.9 - 3.8 GHz and support HyperThreading / SMT (8 threads).

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

The performance of the i7-7700T is slightly faster than the Core i5-7600K with sufficient cooling and TDP settings. Therefore, the CPU is fine to handle even demanding tasks and apps.

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1150 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.

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