Has integrated graphics
✔AMD Ryzen 9 7900
With integrated graphics you don’t need to buy a separate graphics card.
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.
CPU temperature
95°C
If the CPU exceeds the maximum operating temperature then problems such as random resets can occur.
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.
number of transistors
Unknown. Help us by suggesting a value.
A higher transistor count generally indicates a newer, more powerful processor.
Performance
CPU speed
12 x 3.7GHz
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.
turbo clock speed
5.4GHz
When the CPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
Has an unlocked multiplier
✔AMD Ryzen 9 7900
Some processors come with an unlocked multiplier which makes them easy to overclock, allowing you to gain increased performance in games and other apps.
L2 cache
12MB
A larger L2 cache results in faster CPU and system-wide performance.
L3 cache
64MB
A larger L3 cache results in faster CPU and system-wide performance.
L1 cache
768KB
A larger L1 cache results in faster CPU and system-wide performance.
L2 core
1MB/core
More data can be stored in the L2 cache for access by each core of the CPU.
L3 core
5.33MB/core
More data can be stored in the L3 cache for access by each core of the CPU.
Benchmarks
