Intel Pentium G645
The Pentium G645 is a 2 core CPU from Intel released in 2012. This chip has a bad overall score with 951 points in our CPU benchmark. Our gaming benchmark shows that this CPU is an average processor for gaming, with a score of 2076 points. As for multitasking and heavy workloads, the Pentium G645 scores 679 points and 653 points respectively. Indeed, this is a bad rating for very heavy workloads.
The Pentium G645 has 2 cores and 2 threads. This chip has no simultaneous multithreading support, as it has the same number of cores as threads. This Intel CPU has a clock speed of 2.9 GHz.
As for memory, the Pentium G645 makes use of DDR3-1066 memory. The faster the memory, the better. Faster memory means that the CPU doesn't have to wait to get the data it needs. It can accommodate a maximum of 32 GiB of memory. Furthermore, this chip can handle up to 2 channels of RAM, a multichannel memory architecture allows for higher data transfer between the CPU and the memory. However, to take advantage of this, you must have enough memory slots filled.
In terms of cache, the Pentium G645 has 0 MiB of level 2 cache and 3 MiB of level 3 cache. This is a fast memory located close to the processor, which stores copies of frequently used data from main memory.
This CPU has fast connectivity with support for PCI-Express Gen 2. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs.
Power and thermals for the Intel Pentium G645 CPU are a TDP (Thermal Design Power) of 65 watts. This measures the amount of heat the processor produces when running at full load. This isn't a measure of power consumption, but it's a good estimate.
