Intel Core i7-4550U vs Intel Core i7-4650U vs Intel Core i7-4950HQ

Intel Core i7-4550U

► remove Intel 4550U

The Intel Core i7-4550U 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 1.5 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.0 GHz for 1 active core or 2.7 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 almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

The performance of the Core i7-4550U is similar to the old and slightly higher clocked Core i7-3537U. 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 i7-4550U 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.

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.

Intel Core i7-4950HQ

► remove Intel 4950HQ

The Intel Core i7-4950HQ is a high-end quad-core processor for laptops 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 2.4 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.4 GHz (for 4 active cores), 3.5 GHz (for 2 active cores) and 3.6 GHz (for 1 active core). A noteworthy feature is the fast integrated graphics unit (GT3e) with eDRAM memory (128 MB, 77 mm², on-package, 102 GB/s).

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 especially the Hyper-Threading performance. 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 performance of the i7-4950HQ is similar to the slightly faster clocked i7-3840QM (Ivy Bridge based).

The integrated Iris Pro Graphics 5200 GPU offers 40 Execution Units (EUs) clocked at 200 - 1300 MHz (with Turbo Boost), making it significantly faster than the HD 4000 or HD 4600. The additional eDRAM memory further improves performance. As a result, the HD 5200 competes with dedicated mid-range graphics cards.

The i7-4950HQ is rated at a TDP of 47 W including the integrated graphics card, memory controller and VRMs.  Therefore, the CPU is best suited for laptops 15-inches or greater.
