Intel Core i5-4340M vs Intel Core i5-4330M

The Intel Core i5-4340M is a fast dual-core processor for laptops launched in Q1 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 2.9 GHz but can dynamically increase clock rates with Turbo Boost up to 3.6 GHz for 1 active core or 3.5 GHz for 2 active cores. The 2C Turbo clock has not been confirmed yet.

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

Performance

Compared to the Core i5-4330M, the 4340M is clocked just 100 MHz higher and therefore only slightly faster. Overall, the performance is almost on par with the Core i7-4600M. 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 1250 MHz, making it about 30 % faster than a similarly clocked HD 4000. This is slightly slower than the AMD Radeon HD 8650G or a dedicated GeForce GT 720M.

Power Consumption

The i5-4340M is rated at a TDP of 37 W including the graphics card, memory controller and VRMs. Therefore, the CPU is suited for laptops 14-inches or greater.

The Intel Core i5-4330M is a fast dual-core processor for laptops 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 2.8 GHz but can dynamically increase clock rates with Turbo Boost up to 3.5 GHz  for 1 active core or 3.4 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. 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 almost 10 percent compared to Ivy Bridge. Therefore, the i5-4330M is slightly faster than the former top model i7-3540M.

The integrated Intel HD Graphics 4600 offers 20 Execution Units (EUs) clocked at 400 MHz up to 1250 MHz with Turbo Boost, making it about 30 % faster than a similarly clocked HD 4000.

The i5-4330M is rated at a TDP of 37 W including the graphics card, memory controller and VRMs. Therefore, the CPU is suited for laptops 14-inches or greater.
