General info
1.Supports 64-bit
AMD Ryzen 9 3900X
A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps.
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.
Peripheral Component Interconnect Express (PCIe) is a high-speed interface standard for connecting components, such as graphics cards and SSDs, to a motherboard. Newer versions can support more bandwidth and deliver better performance.
If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.
6.Has integrated graphics
AMD Ryzen 9 3900X
With integrated graphics you don’t need to buy a separate graphics card.
Performance
1.CPU speed
12 x 3.8GHz
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.
More threads result in faster performance and better multitasking.
3.L2 cache
6MB
A larger L2 cache results in faster CPU and system-wide performance.
4.L3 cache
64MB
A larger L3 cache results in faster CPU and system-wide performance.
5.turbo clock speed
4.6GHz
When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
6.L1 cache
768KB
A larger L1 cache results in faster CPU and system-wide performance.
Memory
1.RAM speed
3200MHz
It can support faster memory, which will give quicker system performance.
2.maximum memory bandwidth
47.68GB/s
This is the maximum rate that data can be read from or stored into memory.
More memory channels increases the speed of data transfer between the memory and the CPU.
The maximum amount of memory (RAM) supported.
5.Supports ECC memory
AMD Ryzen 9 3900X
Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.
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.
Features
1.Has AES
AMD Ryzen 9 3900X
AES is used to speed up encryption and decryption.
SSE is used to speed up multimedia tasks such as editing an image or adjusting audio volume. Each new version contains new instructions and improvements.
3.Has AVX
AMD Ryzen 9 3900X
AVX is used to help speed up calculations in multimedia, scientific and financial apps, as well as improving Linux RAID software performance.
4.Has MMX
AMD Ryzen 9 3900X
MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
5.Has F16C
AMD Ryzen 9 3900X
F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
6.uses multithreading
AMD Ryzen 9 3900X
Multithreading technology (such as Intel's Hyperthreading or AMD's Simultaneous Multithreading) provides increased performance by splitting each of the processor's physical cores into virtual cores, also known as threads. This way, each core can run two instruction streams at once.
