Intel Core i7-975

The Core i7-975 is a 4 core CPU from Intel released in 2009. This chip has an average overall score at 19% in our CPU benchmark. Our gaming benchmark shows that this CPU is a good processor for gaming, with a score of 30%. As for multitasking and heavy workloads, the Core i7-975 scores 16% and 15% respectively. Indeed, this is an average rating for very heavy workloads.

The Core i7-975 has 4 cores and 8 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 3.3 GHz and a turbo speed of 3.6 GHz : a higher clock speed that can be reached when thermals and power delivery allow.

As for memory, the Core i7-975 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 24 GiB of memory. Furthermore, this chip can handle up to 3 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 not supported on this processor.

Power and thermals for the Intel Core i7-975 CPU are a TDP (Thermal Design Power) of 130 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.
