About the Intel Core i9-12900K CPU

The Intel Core i9-12900K is a 16-core (24-thread) processor built for the desktop CPU market. It launched in Q4 2021 with a suggested retail price of $599. It is part of Intel's Core i9 lineup, which is based on the Alder Lake-S microarchitecture. The i9-12900K is compatible with Intel Socket 1700 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 770 integrated graphics solution.

Memory and Cache

The Core i9-12900K supports DDR4-3200, DDR5-4800 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i9-12900K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1.25 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 30 MB.

Cores and Clock Speeds

The Core i9-12900K features 16 total cores which can process 24 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 16 cores consist of 8 P-Cores and 8 E-Cores. P-Cores are designed for high-performance tasks and E-Cores are intended for efficiency and lighter tasks. The base clock speed of the CPU is 3.2 GHz, and it can boost up to 5.2 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 i9-12900K includes an integrated graphics solution called UHD Graphics 770. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.

Benchmark Performance & Value

The Core i9-12900K has the 20th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 70.89% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 26,223 score and $599 launch price (MSRP) gives it a performance per dollar of 43.78. This is the 63rd best in value for the 3DMark 11 Perf. Physics benchmark.

About the AMD E2-1800 CPU

The AMD E2-1800 is a 2-core (2-thread) processor built for the desktop CPU market. It launched in Q2 2012. It is part of AMD's E2 lineup, which is based on the Zacate 2 microarchitecture. The E2-1800 is compatible with AMD Socket FT1 motherboards and is fabricated on a 40 nm manufacturing process. It features the Radeon HD 7340 integrated graphics solution.

Memory and Cache

The E2-1800 supports DDR3 memory and features a single-channel memory controller, allowing it to utilize 1 memory modules simultaneously. In terms of cache, the E2-1800 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 512 KB, is larger but slower than the L1.

Cores and Clock Speeds

The E2-1800 features 2 total cores which can process 2 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1700.0 MHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The E2-1800 includes an integrated graphics solution called Radeon HD 7340. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.

Benchmark Performance

The E2-1800 has the 707th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 1.99% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
