Intel Core i3-6157U vs Intel Core i7-7920HQ

Intel Core i3-6157U

► remove from comparison Intel 6157U

The Intel Core i3-6157U is a dual-core SoC based on the Skylake architecture and has been launched in September 2015. The CPU can be found in medium-sized ultrabooks as well as normal notebooks. In addition to two CPU cores with Hyper-Threading clocked at 2.4 GHz (no Turbo Boost), the chip also integrates an Iris Graphics 550 GPU with 64 MB of eDRAM memory as well as a dual-channel DDR4-2133/DDR3L-1600 memory controller. The SoC is manufactured using a 14 nm process with FinFET transistors.

Architecture

Skylake replaces both Haswell and Broadwell and brings the same microarchitecture in every TDP class from 4.5 to 45 W. The extensive improvements of the Skylake design include increased out-of-order buffers, optimized prefetching and branch prediction as well as additional performance gains through Hyper-Threading. Overall, however, performance per clock has been increased by only 5 to 10 percent (compared to Haswell) respectively under 5 percent (compard to Broadwell), which is quite modest for a new architecture ("Tock").

Furthermore, the organisation of the eDRAM cache has been modified. Instead of acting like a victim cache, which has to be adressed via the L3/LLC, the eDRAM can now be adressed directly by programms just like the main memory. The size is still 128 MB for the quad-core models (4C + GT4e), while the dual-core chips (2C + GT3e) only offer 64 MB.

Performance

According to the specified clock rates and the improved architecture, the Core i3-6157U should perform similar to a Core i3-5157U (Broadwell, 15 W). Thus, the CPU has sufficient power for office and multimedia purposes as well as more demanding applications and multitasking.

Graphics

The integrated graphics unit called Iris Graphics 550 represents the "GT3e" version of the Skylake GPU (Intel Gen. 9). The 48 Execution Units, also called EUs, are clocked at 350 - 1000 MHz and offer (thanks to the fast eDRAM cache) a performance similar to a dedicated GeForce 930M. Games of 2015 can thus be played smoothly in low or medium settings. For more information about performance and features, check our page for the Iris Graphics 550.

Power Consumption

Specified at a TDP of 28 W (including CPU, GPU and memory controller), the CPU is best suited for medium-sized notebooks (13-inches and above). Optionally, the TDP can be lowered to 23 watts (cTDP down), reducing both heat dissipation and performance.

Intel Core i7-7920HQ

► remove from comparison Intel i7-7920HQ

The Intel Core i7-7920HQ is a fast quad-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the consumer series at the time of the announcement. Only the Xeon E3-1535M v6 is faster (100 - 200 MHz higher Turbo clocks). Besides four cores including Hyper-Threading support running at 3.1-4.1 GHz (4 cores up to 3.7 GHz, 2 cores up to 3.9 GHz), the processor is also equipped with the HD Graphics 630 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It is 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 is a bit higher compared to the Skylake predecessor Core i7-6920HQ (2.9-3.8 GHz) thanks to slightly higher clocks (up to 7.9%), so it is the fastest mobile consumer processor in the beginning of 2017 (mobile Xeon E5-1535M v6 has even higher Turbo clocks). The performance is sufficient even for very demanding tasks and on par with powerful desktop quad-core processors.

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1100 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.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel still specifies the TDP with 45 Watts, but it can also be reduced to 35 Watts by the notebook manufacturers (cTDP down). This will obviously affect the performance, because the Turbo Boost cannot be maintained for longer periods.
