Core i9-10900K vs Xeon Gold 6126 comparison

According to the hardwareDB Benchmark tool, the Xeon Gold 6126 is faster than the Core i9-10900K. Despite this, the Core i9-10900K has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon Gold 6126 has slightly more cores with 12 cores compared to the Core i9-10900K that has 10 cores. It also has more threads than the Core i9-10900K. With our hardware info, we find that the Core i9-10900K has a slightly higher clock speed than the Xeon Gold 6126. Also, the Core i9-10900K has a significantly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Xeon Gold 6126 has more L2 cache than the Core i9-10900K. The Xeon Gold 6126 also has significantly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i9-10900K has more threads than cores. Each physical core is split into multiple threads.
