Core i7-10510U vs Core i9-12900T specs and performance

Our benchmark analysis concludes that the Core i7-10510U performs better than the Core i9-12900T. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-12900T in all gaming tests too.

With info from our database, we find that the Core i9-12900T has significantly more cores with 16 cores whereas the Core i7-10510U has 4 cores. It also has more threads than the Core i7-10510U. These CPUs have different clock speeds. Indeed, the Core i7-10510U has a slightly higher clock speed compared to the Core i9-12900T. Furthermore, both these CPUs have identical turbo speeds. A Core i7-10510U CPU outputs less heat than a Core i9-12900T CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i9-12900T has significantly more L2 cache when compared to the Core i7-10510U. The Core i9-12900T also has significantly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-10510U has more threads than cores. Each physical core is split into multiple threads.
