Intel Core i5-8400B processor review - Benchmark and Specs
The base and maximum clock speed of the CPU Intel Core i5-8400B, number of processing cores and threads.
CPU Cores and Base Frequency
The general performance of a CPU can easily be determined based on the number of its cores and the thread count, as well as the base frequency and Turbo frequency. The more GHz and cores a CPU has, the better. Please note that high technical specs require using a powerful cooling system and a quality chipset (check VRM on the motherboard).
|Frequency:||2.80 GHz||CPU Cores:||6|
|Turbo (1 Core):||3.80 GHz||CPU Threads:||6|
|Turbo (6 Cores):||4.00 GHz|
Some manufacturers complement their CPUs with graphic chips, such a solution being especially popular in laptops. The higher the clock frequency of a GPU is and the bigger its memory, the better.
|GPU name:||Intel UHD Graphics 630|
|GPU frequency:||0.35 GHz||GPU (Turbo):||1.15 GHz|
|Max. Memory:||64 GB||Max. displays:||3|
|Technology:||14 nm||Release date:||Q4/2017|
Hardware codec support
Here we deal with specs that are used by some CPU manufacturers. These numbers are mainly technical and can be neglected for the purpose of the comparison analysis.
|h264:||Decode / Encode|
|JPEG:||Decode / Encode|
|h265 8bit:||Decode / Encode|
|h265 10bit:||Decode / Encode|
|VP8:||Decode / Encode|
|VP9:||Decode / Encode|
|AVC:||Decode / Encode|
Memory & PCIe
These are memory standards supported by CPUs. The higher such standards, the better a CPU’s performance is.
|Memory type:||DDR4-2666||Max. Memory:||64 GB|
|PCIe version:||3.0||PCIe lanes:||16|
Data encryption support
|TDP:||65 W||Tjunction max.:||100 °C|
|TDP up:||--||TDP down:||--|
These are key parameters that will help you determine which CPU is better. Pay special attention to the release date, technological aspects of the manufacturing process (measured in nanometers), and the third-level cache (L3).
|L3-Cache:||9.00 MB||Technology:||14 nm|
|Architecture:||Coffee Lake||Virtualization:||VT-x, VT-x EPT, VT-d|
|Socket:||BGA 1440||Release date:||Q2/2018|
|Market price:||ca. 260 $|
Devices using this processor
