Intel Core i5-6400T vs Intel Core i5-6500 vs Intel Core i5-6600T

Intel Core i5-6400T

► remove from comparison

The Intel Core i5-6400T is a frugal quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 2.2-2.8 GHz and does not support Hyperthreading (only 4 threads simultaneously).

Architecture

Intel uses Skylake to replace both Broadwell as well as Haswell and therefore uses one core design for all TDP classes between 4.5-45 Watts. Several improvements of the Skylake architecture include bigger Out-to-Order-Buffer, optimizations for pre-fetching as well as bigger gains by Hyperthreading. However, the changes are small for a "Tock" – a new micro architecture – in general, so the per-MHz performance is only between 5-10 % (compared to Haswell) or less than 5 % higher (compared to Broadwell), respectively.

Performance

Depending on the utilization of Hyperthreading, the performance is roughly on par with the old Core i7-2670QM mobile processor (Sandy Bridge, 2.2-2.8 GHz, Hyperthreading), but sometimes also much higher.

Graphics

Graphics are handled by the integrated Intel HD Graphics 530 with 24 EUs (Execution Units), which is clocked at 350 - 950 MHz. Compared to the HD Graphics 4600 (Haswell, 20 EUs), the performance is increased by around 25 percent. The overall GPU performance is still low-end, so modern games can, if at all, only be played smoothly with low settings.

Power Consumption

Intel specifies the TDP with 35 Watts, so it can also be used in notebooks (although bigger ones).

Intel Core i5-6500

► remove from comparison

The Intel Core i5-6500 is a mid-range quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 3.2 - 3.6 GHz and does not support Hyperthreading (only 4 threads simultaneously).

Several improvements of the Skylake architecture include bigger Out-to-Order-Buffer, optimizations for pre-fetching as well as bigger gains by Hyperthreading. However, the changes are small for a "Tock" – a new micro architecture – in general, so the per-MHz performance is only between 5-10 % (compared to Haswell) or less than 5 % higher (compared to Broadwell), respectively.

Performance

The performance is similar to the old Core i5-3570K of the Sandy Bridge generation. Therefore, it should be sufficient even for demanding tasks.

Graphics

Graphics are handled by the integrated Intel HD Graphics 530 with 24 EUs (Execution Units), which is clocked at 350 - 1050 MHz. Compared to the HD Graphics 4600 (Haswell, 20 EUs), the performance is increased by around 25 percent. The overall GPU performance is still low-end, so modern games can, if at all, only be played smoothly with low settings.

Power Consumption

Intel specifies the TDP with 65 Watts.

Intel Core i5-6600T

► remove from comparison

The Intel Core i5-6600T is a frugal quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 2.7-3.5 GHz and does not support Hyperthreading (only 4 threads simultaneously).

Several improvements of the Skylake architecture include bigger Out-to-Order-Buffer, optimizations for pre-fetching as well as bigger gains by Hyperthreading. However, the changes are small for a "Tock" – a new micro architecture – in general, so the per-MHz performance is only between 5-10 % (compared to Haswell) or less than 5 % higher (compared to Broadwell), respectively.

Performance

The performance should be similar to the old Core i5-2500K desktop processor (but at a much lower TDP) as well as the mobile Core i5-6440HQ (100 MHz lower base clock and GPU Turbo clock, 10 Watts higher TDP).

Graphics

Graphics are handled by the integrated Intel HD Graphics 530 with 24 EUs (Execution Units), which is clocked at 350 - 1150 MHz. Compared to the HD Graphics 4600 (Haswell, 20 EUs), the performance is increased by around 25 percent. The overall GPU performance is still low-end, so modern games can, if at all, only be played smoothly with low settings.
