Intel Xeon E5-2640
The Xeon E5-2640 is a 6 core CPU from Intel released in 2012. This chip has a good overall score at 34% in our CPU benchmark. Our gaming benchmark shows that this CPU is a very good processor for gaming, with a score of 44%. As for multitasking and heavy workloads, the Xeon E5-2640 scores 30% and 29% respectively. Indeed, this is an average rating for very heavy workloads.
The Xeon E5-2640 has 6 cores and 12 threads. This CPU makes use of simultaneous multithreading technology to improve performance on parallel tasks. Each physical CPU core is divided into multiple logical processors. This Intel CPU has a clock speed of 2.5 GHz and a turbo speed of 3 GHz : a higher clock speed that can be reached when thermals and power delivery allow.
As for memory, the Xeon E5-2640 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 384 GiB of memory. Furthermore, this chip can handle up to 4 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. Error correcting memory is supported on this processor.
In terms of cache, the Xeon E5-2640 has 1 MiB of level 2 cache and 15 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 3. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs. It has a total of 40 PCIe lanes.
Power and thermals for the Intel Xeon E5-2640 CPU are a TDP (Thermal Design Power) of 95 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 good estimate.
