The Intel Core i7-7700HQ is a fast quad-core processor for notebooks based on the Kaby Lake H architecture (7th generation Core), which was announced in January 2017 at CES. It is the successor to the Core i7-6700HQ from the Skylake generation and is manufactured in an improved 14 nm+ process, so the clocks are 200 MHz higher at the same TDP. The architecture was not changed, only the video engine got an update (see our Kaby Lake article).
The integrated graphics card is called Intel HD Graphics 630, but the architecture does not differ from the 530 GPU from the Skylake generation and only the clocks are slightly higher.
Performance
Thanks to the 200 MHz higher clocks (5.5-7.6% depending on the Boost), the CPU performance is increased and roughly on par with the Core i7-6970HQ (2.8-3.7 GHz but with 128 MB eDRAM). The TDP can also be reduced to 35 Watts (cTDP down), but this will reduce the performance.
Power Consumption
Due to its 45-Watt TDP, the CPU will be used in bigger notebooks with at least 15 inches most of the time.
The Intel Celeron N3350 is an Apollo Lake family, dual-core, ultra-low-power processor (SoC) that saw the light of day in 2016. Its two cores run at 1.1 GHz to 2.4 GHz; these are not Hyper-Threading-enabled meaning there are no additional threads. This chip has a fairly competent integrated graphics solution, the Intel HD Graphics 500, and eats very little (~6 W).
Amusingly enough, Intel keeps making and selling the Celeron as of late 2022, albeit the price has dropped from about $100 to about $20 per unit making the CPU even more popular with ultra-budget nettop and laptop makers.
Architecture & Features
Just like other Celeron N, Celeron J, Pentium N, Pentium J processors, this Celeron is notable for its small die size. It is easy to manufacture, lowering the costs and enabling Intel to compete with various ARM-based products (hello, Raspberry Pi).
The Celeron N3350 features the Goldmont CPU microarchitecture. This replaces the dated Silvermont (2013), bringing with it several welcome improvements and making for a double-digit IPC improvement. There is still no L3 cache to be found here, however, it now takes less cycles to perform many operations.
The Celeron is compatible with DDR3L-1866, LPDDR3-1866, LPDDR4-2400 RAM. Intel's guidelines state that up to 8 GB are supported; that being said, various forum users report that the CPU functions just fine if mated to 16 GB and even 32 GB of RAM. The chip features six PCI-Express 2.0 lanes for connecting various devices, meaning a four-lane NVMe SSD will not be able to deliver a data transfer rate of more than 2 GB/s. eMMC and SATA storage is supported natively, too.
This Intel CPU is Secure Boot-compatible; technically, it will have no issue running 64-bit Windows 11. However, Microsoft only allows Windows 11 to be installed on systems with CPUs released in 2017 or later, making 64-bit Windows 10 the only OS that the Celeron is officially compatible with.
Last but not the least, please keep in mind that this is not a user-replaceable CPU. It gets permanently soldered to the motherboard (BGA1296 socket interface).
Performance
The average N3350 in our database is just as fast as the Atom x5-Z8300 and the Core 2 Duo SU7300, as far as multi-thread benchmark scores are concerned. Which is not fast at all. In fact, the two cores of this Celeron trail behind a single core of any half-decent CPU such as Intel's very own Core i3-7130U. A proper x86 CPU, Celeron N3350 will let you run nearly any Windows app, the caveat being that you will have to wait for several seconds every time you click on something. Windows 10 takes nearly a minute to fully boot with this CPU.
Graphics
The Intel HD Graphics 500 (Apollo Lake) is the highlight of this little Celeron. As far as the feature set is concerned, the HD Graphics 500 is not much different from the HD Graphics 520 or any other graphics adapter that full-blown six-generation Intel Core i3/i5/i7 chips have. This iGPU is compatible with DX12; it will drive up to 3 monitors with resolutions as high as 2160p60. It will happily decode VP9 and AVC-encoded videos, too. These are the two codecs that YouTube mostly relies on, as of 2021.
It's not all roses and sunshine. To keep power consumption under control, the number of Execution Units was reduced to 12 (the HD Graphics 520 has 24 EUs at its disposal, for reference). Besides, the UHD Graphics runs at up to 650 MHz which is not a lot. Very few games will be playable on this graphics solution - mostly, ones that were released in the 2000s or even in the 1990s.
Power consumption
The Celeron's default TDP (also known as the Power Limit 1) is 6 W, making it a great option for passively cooled systems. Increasing the PL1 by one or two watts, which many systems built around Apollo Lake allow one to do, makes for a much more responsive user experience, speaking subjectively.
Energy efficiency isn't great here, as Intel's 14 nm processes are very old as of mid 2022.
The Intel Core i5-7267U 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 3.1-3.5 GHz (two cores also up to 3.5 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.
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 28-Watt CPU should be on par with the Core i7-7500U (2.7-3.5 GHz, no eDRAM, 15 Watts), but it should be a bit slower on practice due to the missing level 4 eDRAM and the lower TDP. This means the i5 is still one of the faster dual-core processors and should be sufficient for most scenarios. Some games might still require a real quad-core processor and therefore nit run perfectly on the dual-core processor, 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 300-1050 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.
