► remove from comparison![Intel i5-9400F](fileadmin/_processed_/8/1/csm_i5_9400F_1_8324deb4a3.jpg)
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 Celeron N5100

The Intel Celeron N5100 is a quad-core SoC of the Jasper Lake series that is primarily intended for inexpensive notebooks and was announced in early 2021. The four Tremont CPU cores clock between 1.1 and 2.8 GHz (single core Burst) and offer no HyperThreading (SMT). The N5100 uses 1.5 MB L2 and 4 MB L3 cache. The chip is manufactured in 10nm at Intel (most likely in the same process as Ice Lake).
Architecture
The processor architecture is called Tremont and a complete redesign compared to the old Golmont Plus cores in the predecessor. According to Intel, the single thread performance of a core could be improved by 30% on average (10 - 80% in all tests of SPECint and SPECfp).
Features
In addition to the quad-core CPU block, the SoC integrates a 24 EU Intel UHD Graphics GPU clocked from 350 - 800 MHz and a LPDDR4(x) dual channel memory controller (up to 16 GB and 2933 MHz). The chip now also partly integrates Wi-Fi 6 (Gig+), 8 PCIe 3.0 lanes, 14 USB 2.0/ 3.2 ports and two SATA 6.0 ports. The package got bigger and measures 35 x 24 mm (compared to 25 x 24 mm for the N5030 e.g.). The SoC is directly soldered to the mainboard (BGA) and can't be easily replaced.
Performance
While we have not tested a single system powered by the N5100 as of August 2023, it's safe to expect the chip to be 10% to 20% slower than the N6000, as far as multi-thread performance is concerned. In other words, this is a fairly slow processor that is unlikely to make anybody happy.
Power Consumption
Like most other N-class Intel processors, this Celeron has a 6 W default TDP (also known as the long-term power limit). This is rather low; a small metal plate is all it takes to dissipate heat generated by such a CPU.
The Celeron N5100 is manufactured on Intel's first-generation or second-generation [no exact data available] 10 nm process for average, as of early 2023, energy efficiency.
Intel Core i9-9900T

The Intel Core i9-9900T is a high end power efficient desktop processor based on the Coffee Lake architecture. Compared to the similar named top model Core i9-9900K, the 9900T offers lower clock speeds (2.1 - 4.4 GHz versus 3.6 - 5 GHz) and a reduced TDP of 35 versus 95 Watt. It still offers all 8 cores and 16 threads and is intended for small chassis or laptops.
The performance is clearly behind the Core i9-9900K and more in the realm of the older 6-core Coffee Lake CPUs.
The integrated Intel UHD Graphics 630 graphics card is clocked at up to 1.2 GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).
