Intel Core i7-4578U vs Intel Core i7-4712MQ vs Intel Core i7-4930MX

Intel Core i7-4578U

► remove Intel 4578U

The Intel Core i7-4578U is a LV (low voltage) dual-core processor for large ultrabooks launched in Q3/2014. It is based on the Haswell architecture and is manufactured in 22nm. Due to Hyper-Threading, the two cores can handle up to four threads in parallel, leading to better utilization of the CPU. Each core offers a base speed of 3.0 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.5 GHz.

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, improving the performance per clock by almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

Performance

The performance of the Core i7-4578U is slightly above the older and somewhat higher clocked Core i7-3540M. However, when using new instruction sets such as AVX2 the performance can be significantly better. Thus, the CPU has sufficient power for office and multimedia purposes as well as more demanding applications.

Graphics

The integrated Iris Graphics 5100 offers 40 Execution Units (EUs) clocked at 200 - 1200 MHz with Turbo Boost, making it significantly faster than the HD Graphics 4000. As a result, the Iris Graphics competes with dedicated lower mid-range graphics cards (e.g. GeForce GT 720M).

Power Consumption

The i7-4578U is rated at a TDP of 28 W including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for larger, well-cooled ultrabooks.

Intel Core i7-4712MQ

► remove Intel 4712MQ

The Intel Core i7-4712MQ 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 2.3 GHz but can dynamically increase clock rates with Turbo Boost up to 3.0 GHz (for 4 active cores), 3.2 GHz (for 2 active cores) and 3.3 GHz (for 1 active core). In contrast to the Core i7-4712HQ, the 4712MQ is not soldered, has a slightly lower clocked GPU an doesn't support VT-d.

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.

The performance of the Core i7-4712MQ is similar to the Core i7-4750HQ and slightly above the Ivy Bridge-based i7-3630QM. Even very demanding software or multitasking will be handled easily.

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.

With a TDP of only 37 W (including graphics card, memory controller and VRMs), the Core i7-4712MQ is specified at the level of mobile dual-core CPUs. Therefore, even smaller laptops can use the Core i7.

Intel Core i7-4930MX

► remove Intel 4930MX

The Intel Core i7-4930MX is a high-end quad-core processor for laptops and successor of the i7-3940XM. It is based on the Haswell architecture and was launched in Q2/2013. 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 3.0 GHz but can dynamically increase clock rates with Turbo Boost up to 3.7 GHz (for 4 active cores), 3.8 GHz (for 2 active cores) and 3.9 GHz (for 1 active core). Furthermore, the Extreme CPUs offer an unlocked multiplicator for easy overclocking.

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.

Due to these changes, the performance per clock has been improved by about 10 percent compared to Ivy Bridge. Therefore, the 4930MX is almost 10 % faster than the former i7-3940XM.

The integrated Intel HD Graphics 4600 offers 20 Execution Units (EUs) clocked at 400 MHz up to 1350 MHz with Turbo Boost, making it about 30 % faster than the HD 4000.

The i7-4930MX is rated at a TDP of 57 W including graphics card, memory controller and VRMs.  Therefore, the CPU is only suited for laptops 17-inches or greater.
