Intel Core i5-8257U processor review - Benchmark and Specs
The base and maximum clock speed of the CPU Intel Core i5-8257U, 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:||1.40 GHz||CPU Cores:||4|
|Turbo (1 Core):||3.90 GHz||CPU Threads:||8|
|Turbo (4 Cores):||3.20 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 Iris Plus Graphics 645|
|GPU frequency:||0.30 GHz||GPU (Turbo):||1.05 GHz|
|Max. Memory:||32 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:||DDR4-2400 SO-DIMM LPDDR3-2133||Memory channels:||2|
Data encryption support
|TDP:||15 W||Tjunction max.:||--|
|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:||6.00 MB||Technology:||14 nm|
|Architecture:||Coffee Lake U||Virtualization:||VT-x, VT-x EPT, VT-d|
|Socket:||BGA 1528||Release date:||Q3/2019|
|Market price:||ca. 320 $|
Devices using this processor
You probably know already what devices use CPUs. These can be a desktop or a laptop.
|Used in:||Apple MacBook Pro 13 (2019)|
It is the updated version of the Cinebench R15 benchmark. This version provides improved benchmark accuracy at testing of processors. Cinebench R20 is based on Cinema 4 Suite. It is the software used to create 3D forms. The benchmark runs for single-core test procedure without counting of hyperthreading ability.
It is the new version of the benchmark which is developed on the basis of Cinebench R15 (both versions are operated on the basis of Cinema 4 - the most popular 3D modeling software). Cinebench R20 is used for multi-core processor performance benchmark tests and hyperthreading ability.
It is the updated version of Cinebench 11.5. As all new versions, the updated benchmark is based on Cinema 4 Suite software. The latter is used for creation of 3D models and forms. Cinebench R15 is used for single-core processor performance benchmark test. The hyperthreading ability doesn't count.
This benchmark is the updated version of the Cinebench 11.5 which is based on Cinema 4 Suite soft (it is widely used for 3D production). Cinebench R15 can be used for multi-core processor performance benchmark testing. The test produces precise and accurate results.
This test serves for determining the performance of integrated graphics in Intel and AMD processors. The result is the estimated computing power in the Single-Precision FP32 mode. The computing power in games can vary despite the differences in the capacity of videocards.
Geekbench 5 benchmark is the newest software suit. It allows to account for the effect of memory performance on processor performance. Completely new algorithms provide the quite accurate benchmark testing results of the single-core CPU.
Geekbench 5 software suite shows benchmark testing results of the memory performance and speed of the multi-core processor. The higher the GeekBench score, the better processor. Here the hyperthreading ability is counted.
PassMark is one of the most popular benchmark in the world. It tests entire and overall performance of the central processing unit (mathematical calculations, compression and decompression speed, 2D&3D graphic tests). Below you will see benchmark testing results for the processor and its score. Please note that data can differ from the real-world situations.
