About the Intel Core i9-7900X CPU
The Intel Core i9-7900X is an end-of-life 10-core (20-thread) processor built for the desktop CPU market. It launched in Q2 2017 with a suggested retail price of $999. It is part of Intel's Core i9 lineup, which is based on the X-Series 7th Gen microarchitecture. The i9-7900X is compatible with Intel Socket 2066 motherboards and is fabricated on Intel's 14 nm manufacturing process.
Memory and Cache
The Core i9-7900X supports DDR4 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Core i9-7900X has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 14 MB.
Cores and Clock Speeds
The Core i9-7900X features 10 total cores which can process 20 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.3 GHz, and it can boost up to 4.5 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.
Integrated Graphics
The Core i9-7900X does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
Benchmark Performance & Value
The Core i9-7900X has the 133rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 41.25% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 15,260 score and $999 launch price (MSRP) gives it a performance per dollar of 15.28.
