Performance
CPU speed
8 x 3.6 GHz (Intel Core i9-9900K)
The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
RAM
64GB
Random-access memory (RAM) is a form of memory used to store working data and machine code. Having more RAM is particularly useful for multitasking, allowing you to run more programs at once or have more tabs open in your browser.
GPU clock speed
350 MHz (Intel Core i9-9900K)
The clock speed of the graphics processing unit (GPU).
This benchmark measures the performance of the CPU using multiple threads.
This benchmark measures the performance of the CPU using a single thread.
CPU threads
16 threads (Intel Core i9-9900K)
More threads result in faster performance and better multitasking.
DDR (Double Data Rate) memory is the most common type of RAM. Newer versions of DDR memory support higher maximum speeds and are more energy-efficient.
VRAM
4GB
VRAM (video RAM) is the dedicated memory of a graphics card. More VRAM generally allows you to run games at higher settings, especially for things like texture resolution.
GPU turbo
1200 MHz (Intel Core i9-9900K)
When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
Display
pixel density
286 ppi
Pixel density is a measurement of a screen's resolution, expressed as the number of pixels per inch (PPI) on the screen. A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience.
resolution
3840 x 2160 px
Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
