Intel Core i7-4940MX vs Intel Core i7-4702MQ vs Intel Core i7-4650U

Intel Core i7-4940MX

► remove Intel 4940MX

The Intel Core i7-4940MX is a high-end quad-core processor for laptops and successor of the i7-4930MX. It is based on the Haswell architecture and was launched in Q1/2014. 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 3.1 GHz but can dynamically increase clock rates with Turbo Boost up to 3.8 GHz (for 4 active cores), 3.9 GHz (for 2 active cores) and 4.0 GHz (for 1 active core). Furthermore, the Extreme CPUs offer an unlocked multiplicator for easy overclocking.

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, increasing the performance per clock by about 5 - 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

Performance

Compared to the Core i7-4930MX, the 4940MX is clocked just 100 MHz higher and therefore only slightly faster. Overall, the performance is similar to the Desktop Core i7-4770K. Even extremly 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 1350 MHz with Turbo Boost, making it about 30 % faster than the HD 4000. This is slightly slower than the AMD Radeon HD 8650G, but similar to a dedicated GeForce GT 720M.

Power Consumption

The i7-4940MX 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.

Intel Core i7-4702MQ

► remove Intel 4702MQ

The Intel Core i7-4702MQ 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 2.2 GHz but can dynamically increase clock rates with Turbo Boost up to 2.9 GHz (for 4 active cores), 3.1 GHz (for 2 active cores) and 3.2 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. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

The performance of the Core i7-4702MQ is slightly above a similarly clocked Ivy Bridge processor due to the architectural improvements. As a result, overall performance is similar to the Ivy Bridge based Core i7-3630QM.

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 Watt, the Core i7-4702MQ is specified at the level of mobile dual-core CPUs. Therefore, even smaller laptops can use the Core i7.

Intel Core i7-4650U

► remove Intel 4650U

The Intel Core i7-4650U is an ULV (ultra low voltage) dual-core processor for ultrabooks launched in Q2 2013. 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 1.7 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.3 GHz for 1 active core or 2.9 GHz for 2 active cores.

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 alomst 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

The performance of the Core i7-4650U is similar to the old and slightly higher clocked Core i7-3687U. 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.

The integrated HD Graphics 5000 offers 40 Execution Units (EUs) clocked at 200 - 1100 MHz with Turbo Boost, making it significantly faster than the HD Graphics 4000. As a result, the HD 5000 competes with dedicated lower mid-range graphics cards.

The i7-4650U is rated at a TDP of 15 W including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for small ultrabooks 11-inches or greater.
