Intel Core i7-4820K vs AMD Ryzen Z1 Extreme

The Intel Core i7-4820K is a 4-core (8-thread) processor built for the desktop CPU market. It launched in Q3 2013. It is part of Intel's Core i7 lineup, which is based on the Ivy Bridge-E microarchitecture. The i7-4820K is compatible with Intel Socket 2011 motherboards and is fabricated on Intel's 22 nm manufacturing process.

Memory and Cache

The Core i7-4820K supports DDR3 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Core i7-4820K 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 10 MB.

Cores and Clock Speeds

The Core i7-4820K features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.7 GHz, and it can boost up to 3.9 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 i7-4820K does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

The AMD Ryzen Z1 Extreme is a 8-core (16-thread) processor built for the mobile CPU market. It launched in Q2 2023. It is part of AMD's Ryzen Z1 lineup, which is based on the Zen 4 microarchitecture. The Z1 Extreme is compatible with AMD Socket FP8 motherboards and is fabricated on TSMC's 4 nm manufacturing process. It features the Radeon 780M integrated graphics solution.

Memory and Cache

The Ryzen Z1 Extreme supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen Z1 Extreme 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 16 MB.

Cores and Clock Speeds

The Ryzen Z1 Extreme 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 5.1 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 Ryzen Z1 Extreme includes an integrated graphics solution called Radeon 780M. 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 Ryzen Z1 Extreme has the 79th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 51.21% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
