AMD EPYC 7773X vs Intel Celeron J4005

The AMD EPYC 7773X is a 64-core (128-thread) processor built for the server CPU market. It launched in Q1 2022 with a suggested retail price of $8,800. It is part of AMD's EPYC lineup, which is based on the Zen 3 microarchitecture. The EPYC 7773X is compatible with AMD Socket SP3 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The EPYC 7773X supports DDR4 memory and features a octa-channel memory controller, allowing it to utilize 8 memory modules simultaneously. In terms of cache, the EPYC 7773X 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. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 768 MB.

Cores and Clock Speeds

The EPYC 7773X features 64 total cores which can process 128 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.2 GHz, and it can boost up to 3.5 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 EPYC 7773X does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

The Intel Celeron J4005 is an end-of-life 2-core (2-thread) processor built for the mobile CPU market. It launched in Q4 2017 with a suggested retail price of $107. It is part of Intel's Celeron lineup, which is based on the Goldmont Plus microarchitecture. The J4005 is compatible with Intel BGA 1090 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD Graphics 600 integrated graphics solution.

Memory and Cache

The Celeron J4005 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Celeron J4005 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 56 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 4 MB, is larger but slower than the L1.

Cores and Clock Speeds

The Celeron J4005 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 2000.0 MHz, and it can boost up to 2.7 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 Celeron J4005 includes an integrated graphics solution called UHD Graphics 600. 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 Celeron J4005 has the 693rd best 3DMark 11 Performance Physics score among the 791 benchmarked CPUs in our database. It achieves 4.90% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X. Its 1,877 score and $107 launch price (MSRP) gives it a performance per dollar of 17.54. This is the 196th best in value for the 3DMark 11 Perf. Physics benchmark.
