Intel Core i5-9400F vs Intel Core i5-8500T vs Intel Core i5-8500
Intel Core i5-9400F
► remove from comparison
The Intel Core i5-9400F is a six-core desktop processor based on the Coffee Lake architecture introduced in October 2018 along with the flagship Intel Core i9-9900K. The processor clocks at 2.9-4.1 GHz and can process up to 6 threads simultaneously. The Intel Core i5-9400F is manufactured in the improved 14-nm process (14nm++).
Performance
Compared to the Intel Core i5-8400, the performance could only be increased slightly. Performance increases of up to 10 percent can be expected. Both processors (old and new) still do not offer hyperthreading. The performance increase therefore only adds up to small architecture improvements and a slightly higher basic and turbo clock rate. This CPU is suitable for everyday office use, which does not require large coolers due to the low waste heat. But games are also among the application areas, because in games the Intel Core i5-9400F clearly beats the Intel Core i3-9100F. Here the six cores are paying off in the meantime.
Graphics unit
The Intel Core i5-9400F is a processor without integrated graphics unit. If you value an iGPU, you should take a closer look at the Intel Core i5-9400, as it offers the entry level Intel UHD Graphics 630.
Power consumption
Intel puts the Thermal Design Power (TDP) at 65 watts. This means there is no need for large cooling systems, which also allows installation in very compact housings.
Intel Core i5-8500T
► remove from comparisonThe Intel Core i5-8500T is a desktop processor of the Coffee Lake generation. It offers 6 cores clocked at 2.1 - 3.5 GHz and is manufactured in the again improved 14nm process (14nm++). As a "T" model, te i5-8500T is rated with a low 35 Watt TDP and therefore sometimes even used in laptops.
Thanks to the additional 2 cores, the Coffee Lake 6-core CPUs can offer a performance uplift of up to 50% in multithreaded workloads compared to the Kaby Lake predecessors.
Intel Core i5-8500
► remove from comparison
The Intel Core i5-8500 is a mid-range 6-core CPU. The processor belongs to the Coffee Lake generation and was presented in April 2018. It does not support Hyper-Threading, which means it can run six threads simultaneously. The base clock rate is 3 GHz and the CPU can speed up to 4.1 GHz under high load. Despite belonging to the new generation of CPUs, the Core i5-8500 is manufactured in an improved 14nm process.
Performance
The processor offers a strong performance increase compared to the Core i5-7500 due to its two additional cores. Single-core performance has not improved significantly compared to its Kaby Lake predecessor. As a mid-range model, the Core i5-8500 should be suitable for demanding games and programs.
Graphics
The integrated Intel UHD Graphics 630 iGPU is supposed to offer higher performance as its clock rate has been increased by 50-100 MHz. The build is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.
Power Consumption
Intel specifies the TDP with 65 watts. Therefore, well-dimensioned cooling systems should easily manage to deal with the created heat. We expect increased efficiency due to the higher performance.
