General info
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.
The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
Performance
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.
A larger L2 cache results in faster CPU and system-wide performance.
A larger L3 cache results in faster CPU and system-wide performance.
When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
A larger L1 cache results in faster CPU and system-wide performance.
Memory
It can support faster memory, which will give quicker system performance.
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.
The bus is responsible for transferring data between different components of a computer or device.
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.
Features
AES is used to speed up encryption and decryption.
Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.
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.
AVX is used to help speed up calculations in multimedia, scientific and financial apps, as well as improving Linux RAID software performance.
MMX is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
F16C is used to speed up tasks such as adjusting the contrast of an image or adjusting volume.
Benchmarks
This benchmark measures the performance of the CPU using multiple threads.
This benchmark measures the performance of the CPU using a single thread.
