Intel Core i5-6287U vs Intel Core i5-6267U vs Intel Core i5-6440HQ

Intel Core i5-6287U

► remove Intel 6287U

The Intel Core i5-6287U 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 3.1 - 3.5 GHz (2 cores: max. 3.3 GHz), 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 i5-6287U should perform similar to the former Core i5-5350H (Broadwell) and is one of the fastest mobile dual-cores as of late 2015.

Even demanding applications and multitasking are handled easily.

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 - 1100 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 i5-6267U

The Intel Core i5-6267U 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 2.9 - 3.3 GHz (2 cores: max. 3.1 GHz), 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.

Performance

According to the specified clock rates and the improved architecture, the Core i5-6267U should perform similar to the former Core i5-4200H and i5-4310M (Haswell). Even demanding applications and multitasking are handled easily.

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 - 1050 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.

Intel Core i5-6440HQ

► remove Intel 6440HQ

The Intel Core i5-6440HQ is a quad-core processor based on the Skylake architecture, that has been launched in September 2015. In addition to four CPU cores (no Hyper-Threading support) clocked at 2.6 - 3.5 GHz (4 cores: max. 3.1 GHz, 2 cores: max. 3.3 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.

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 (if supported). 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

With up to 4 threads under load, the Core i5-6440HQ performs roughly on par with the Core i7-6700HQ or Core i7-4720HQ (Haswell). However, the Core i7 benefit from Hyper-Threading (up to 25 - 30 percent performance boost) in extensively parallelized software, whereas the Core i5 don't support this feature.

Nevertheless, 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 - 950 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.
