AMD Ryzen Embedded V1605B vs Intel Core i7-4900MQ vs Intel Core i7-4722HQ

The Intel Core i7-4900MQ is a high-end quad-core processor for laptops which has been launched in Q2/2013. It is based on the Haswell architecture and manufactured in 22nm. Due to Hyperthreading, the four cores can handle up to eight threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.8 GHz but can dynamically increase clock rates with Turbo Boost up to 3.6 GHz (for 4 active cores), 3.7 GHz (for 2 active cores) and 3.8 GHz (for 1 active core).

Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports, improving the performance per clock by almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

Due to these changes, the overall performance has been improved slightly compared to Ivy Bridge. Therefore, the 4900MQ is about 10 % faster than the former i7-3840QM.

The integrated Intel HD Graphics 4600 offers 20 Execution Units (EUs) clocked at 400 MHz up to 1300 MHz with Turbo Boost, making it about 30 % faster than the HD 4000.

The i7-4900MQ is rated at a TDP of 47 W including graphics card, memory controller and VRMs.  Therefore, the CPU is only suited for laptops 15-inches or greater.

The Intel Core i7-4722HQ is a high-end quad-core processor for laptops. It is based on the Haswell architecture and manufactured in 22nm. Due to Hyperthreading, the four cores can handle up to eight threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.4 GHz but can dynamically increase clock rates with Turbo Boost up to 3.1 GHz (for 4 active cores), 3.3 GHz (for 2 active cores) and 3.4 GHz (for 1 active core).

Architecture

Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

Performance

The performance of the Core i7-4722HQ is similar to the Core i7-4760HQ and just slightly below the i7-4700MQ (both 47 W TDP). Even very demanding software or multitasking will be handled easily.

Graphics

The integrated Intel HD Graphics 4600 offers 20 Execution Units (EUs) clocked at 400 MHz up to 1150 MHz with Turbo Boost, making it about 30 % faster than the HD 4000 and comparable to a dedicated GeForce 820M.

Power Consumption

With a TDP of only 37 W (including graphics card, memory controller and VRMs), the Core i7-4722HQ is specified at the level of mobile dual-core CPUs. Therefore, even smaller laptops can use the Core i7.
