Intel Core i7-4558U vs Intel Core i7-950

Core i7-4558U vs Core i7-950 benchmarks

According to the hardwareDB Benchmark tool, the Core i7-950 is faster than the Core i7-4558U. Despite this, the Core i7-4558U has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i7-950 has significantly more cores with 4 cores compared to the Core i7-4558U that has 2 cores. It also has more threads than the Core i7-4558U. These CPUs have different clock speeds. Indeed, the Core i7-950 has a slightly higher clock speed compared to the Core i7-4558U. Also, the Core i7-950 has a slightly higher turbo speed. A Core i7-4558U CPU outputs less heat than a Core i7-950 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i7-4558U has more threads than cores. Each physical core is split into multiple threads.
