The Intel Core i7-6920HQ is a high-end quad-core processor for laptops that was released in September 2015. It is part of the Skylake series and is designed to handle demanding tasks with ease, making it a suitable choice for heavy multitasking and running resource-intensive applications.
In terms of architecture, the Skylake design brings microarchitecture improvements in every TDP class from 4.5 to 45 W. These improvements include increased out-of-order buffers, optimized prefetching and branch prediction, as well as additional performance gains through Hyper-Threading. However, the Skylake architecture only offers a 5 to 10 percent increase in performance per clock compared to Haswell, and under 5 percent compared to Broadwell.
The Core i7-6920HQ has a base clock speed of 2.9 GHz, with a maximum speed of 3.8 GHz for 4 cores and 3.6 GHz for 2 cores. It also features an integrated HD Graphics 530 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The GPU has 24 Execution Units clocked at 350 to 1050 MHz, which is around 20 percent faster than the previous HD Graphics 4600. This allows the Core i7-6920HQ to handle most games released in 2015 with smooth performance in low or medium settings.
The Core i7-6920HQ has a specified TDP of 45 W, which makes it suitable for larger laptops with 15-inch or bigger screens. The TDP can be lowered to 35 W through a cTDP down setting, which reduces both heat dissipation and performance. The processor is built using a 14 nm process with FinFET transistors and has a die size of 122 mm2. It supports features such as a dual-channel DDR3L-1600/DDR4-2133 memory controller, AVX, AVX2, Quick Sync, virtualization, AES-NI, vPro, and TXT.
In terms of performance, the Core i7-6920HQ is expected to perform roughly on par with the slightly higher clocked Core i7-4910MQ (Haswell) under normal workloads. However, under prolonged full load, the Skylake chip may take the lead due to its more energy-efficient 14 nm process, which reduces throttling.
The Core i7-6920HQ belongs to the Intel Core i7 Skylake series, which includes other processors such as the Core i7-6970HQ, Core i7-6870HQ, Core i7-6820HK, and Core i7-6820HQ. These processors have similar specifications to the Core i7-6920HQ, with differences in clock speeds and the level of cache. The Core i7-6920HQ has 8 MB of L3 cache, while the other processors in the series have 6 MB or 4 MB of L3 cache.
In addition to its strong performance capabilities, the Core i7-6920HQ also offers several features that make it a versatile processor. One of these features is AVX (Advanced Vector Extensions), which is a set of instructions that improve floating point-intensive applications. AVX2 is an extension of AVX and provides even more instructions for floating point-intensive applications.
The Core i7-6920HQ also includes Quick Sync, which is a hardware-based video encoding and decoding technology that allows for fast conversion of video files. This can be useful for tasks such as creating and editing videos or streaming video content.
Virtualization is another feature of the Core i7-6920HQ, which allows multiple operating systems to run on the same physical server. This can be useful for running multiple applications or for testing and development purposes.
AES-NI (Advanced Encryption Standard New Instructions) is a set of instructions that improve the speed of encryption and decryption tasks. This can be useful for tasks such as secure communication and data protection.
vPro is a set of security and management technologies that are designed to improve the security and manageability of business PCs. This can be useful for businesses that need to secure and manage their PCs in a networked environment.
TXT (Trusted Execution Technology) is a security feature that helps to protect against malicious software attacks by creating a secure environment for applications to run in. This can be useful for tasks such as online banking and shopping, where security is of particular concern.
In conclusion, the Intel Core i7-6920HQ is a high-end quad-core processor that is suitable for demanding tasks and multitasking. Its improved microarchitecture, integrated GPU, and energy-efficient design make it a solid choice for high-end laptops. It also offers a range of features such as AVX, AVX2, Quick Sync, virtualization, AES-NI, vPro, and TXT that make it a versatile processor for a variety of tasks.
