Intel Core i7-6820HK vs Intel Core i7-6920HQ vs Intel Core i7-6650U

Intel Core i7-6820HK

► remove Intel 6820HK

The Intel Core i7-6820HK is a quad-core processor based on the Skylake architecture, that has been launched in September 2015. In addition to four CPU cores with Hyper-Threading clocked at 2.7 - 3.6 GHz (4 cores: max. 3.2 GHz, 2 cores: max. 3.4 GHz), the chip also integrates an HD Graphics 530 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The CPU is manufactured using a 14 nm process with FinFET transistors.

Currently, the i7-6820HK is the only Skylake chip with an unlocked multiplier for easy overclocking (similar to previous Extreme Editions).

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").

Performance

Tanks to the improved architecture, the Core i7-6820HK performs roughly on par with the former Core i7-4900MQ (Haswell) or the Core i7-5700HQ (Broadwell). Under long-lasting full load, the Skylake chip will take the lead over most of its Haswell-based predecessors, as the advanced 14 nm process leads to a higher energy efficiency and reduces throttling. If the 6820HK is overclocked (we've tested up to 4.0 GHz on all 4 cores), the performance will be even better.

Even the most demanding applications and excessive multitasking are handled easily.

Graphics

The integrated graphics unit called HD Graphics 530 represents the "GT2" version of the Skylake GPU (Intel Gen. 9). The 24 Execution Units, also called EUs, are clocked at 350 - 1050 MHz and offer a performance about 20 percent above the old HD Graphics 4600. 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 HD Graphics 530.

Power Consumption

Specified at a TDP of 45 W (including CPU, GPU and memory controller), the CPU is best suited for bigger notebooks 15-inches in size and above. Optionally, the TDP can be lowered to 35 watts (cTDP down), reducing both heat dissipation and performance.

Intel Core i7-6920HQ

► remove Intel 6920HQ

The Intel Core i7-6920HQ is a high-end quad-core processor for notebooks. It's the top-model of the Skylake series and has been presented in September 2015. In addition to four CPU cores with Hyper-Threading clocked at 2.9 - 3.8 GHz (4 cores: max. 3.4 GHz, 2 cores: max. 3.6 GHz), the chip also integrates an HD Graphics 530 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The CPU is manufactured using a 14 nm process with FinFET transistors.

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").

Performance

According to the specified clock rates and the improved architecture, the Core i7-6920HQ should perform roughly on par with the former, slightly higher clocked Core i7-4910MQ (Haswell). Under long-lasting full load, the Skylake chip might take the lead, as the advanced 14 nm process leads to a higher energy efficiency and reduces throttling.

Intel Core i7-6650U

► remove Intel 6650U

The Intel Core i7-6650U is an ULV (ultra low voltage) dual-core SoC based on the Skylake architecture. In September 2015, it's the fastest CPU of the 15 W series (besides the i7-6600U) and can be found in ultrabooks as well as normal notebooks. In addition to two CPU cores with Hyper-Threading clocked at 2.2 - 3.4 GHz (2 cores: max. 3.2 GHz), the chip also integrates an Iris Graphics 540 GPU with 64 MB of dedicated eDRAM memory and 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 i7-6650U should perform similar to a Core i5-4310M (Haswell, 37 W) and is one of the fastest ULV dual-cores as of late 2015. 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 540 represents the "GT3e" version of the Skylake GPU (Intel Gen. 9). The 48 Execution Units, also called EUs, are clocked at 300 - 1050 MHz and offer (thanks to the fast eDRAM cache) a performance sligthly above a dedicated GeForce 920M. 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 540.

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 9.5 watts (cTDP down), reducing both heat dissipation and performance and allowing even more compact designs.
