About the Intel Core i9-11900KB CPU

The Intel Core i9-11900KB is a 8-core (16-thread) processor built for the desktop CPU market. It launched in Q2 2021 with a suggested retail price of $539. It is part of Intel's Core i9 lineup, which is based on the Tiger Lake-H microarchitecture. The i9-11900KB is compatible with Intel BGA 1787 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 750 integrated graphics solution.

Memory and Cache

The Core i9-11900KB supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i9-11900KB 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 24 MB.

Cores and Clock Speeds

The Core i9-11900KB features 8 total cores which can process 16 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 5.3 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 i9-11900KB includes an integrated graphics solution called UHD Graphics 750. 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 i9-11900KB has the 96th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 48.13% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 17,803 score and $539 launch price (MSRP) gives it a performance per dollar of 33.03. This is the 110th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i5-8500 CPU

The Intel Core i5-8500 is an end-of-life 6-core (6-thread) processor built for the desktop CPU market. It launched in Q1 2018 with a suggested retail price of $192. It is part of Intel's Core i5 lineup, which is based on the Coffee Lake microarchitecture. The i5-8500 is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD Graphics 630 integrated graphics solution and is bundled with a E97379-001 cooler.

Memory and Cache

The Core i5-8500 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-8500 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 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 9 MB.

Cores and Clock Speeds

The Core i5-8500 features 6 total cores which can process 6 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.0 GHz, and it can boost up to 4.1 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Core i5-8500 includes an integrated graphics solution called UHD Graphics 630. 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 i5-8500 has the 315th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 21.47% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 7,942 score and $192 launch price (MSRP) gives it a performance per dollar of 41.36. This is the 70th best in value for the 3DMark 11 Perf. Physics benchmark.
