Intel Core i9-9900 vs Intel Core i7-1270P

Core i9-9900 vs Core i7-1270P comparison

In our benchmarks, the Core i9-9900 beats the Core i7-1270P in overall performance. Despite this, the Core i7-1270P has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i7-1270P has significantly more cores with 12 cores compared to the Core i9-9900 that has 8 cores. But they both have the same number of threads. With our hardware info, we find that the Core i9-9900 has a slightly higher clock speed than the Core i7-1270P. Also, the Core i9-9900 has a slightly higher turbo speed. The Core i7-1270P outputs less heat than Core i9-9900 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i7-1270P has significantly more L2 cache than the Core i9-9900. The Core i7-1270P also has slightly more L3 cache.

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 i9-9900 has more threads than cores. Each physical core is split into multiple threads.
