The cache configuration includes 20MB of L2 cache for P-cores, 12MB of L2 cache for E-cores, and 33MB of L3 cache.

Similar to the Core i9-15900K, the Core i7-15700K has a base power (PL1) of 125W and a boost power (PL2) of 177W. It also supports DDR5-6400 memory with two memory channels. The graphics capabilities are provided by the Xe-LPG GPU with 32 execution units (EUs), and it includes the same NPU with an estimated performance of 10 TOPS. The Core i7-15700K is also designed for the LGA1851 socket and offers 20 PCIe Gen 5 lanes.

It’s worth noting that the 15th Gen Arrow Lake processors will be manufactured using Intel’s 20A process for the CPU and TSMC’s 3nm process for the integrated GPU (iGPU). Intel has made some changes compared to previous generations, such as removing hyper-threading and not including AVX-512 support. The power limits have also been reduced, with a PL2 limit of 177W and a PL4 limit of 333W. Additionally, there are rumors that the P-cores and E-cores will be more closely mixed, and the ringbus might receive an update.

Overall, Intel’s 15th Gen Arrow Lake processors are shaping up to be a significant leap forward in terms of performance and efficiency. With upgraded core architectures and process nodes, these processors are expected to deliver a highly competitive lineup. Tech enthusiasts can look forward to their release by the end of 2024, and it will be interesting to see how they stack up against the competition.
