AMD EPYC 7773X vs Intel Core i7-13650HX

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 Core i7-13650HX is a 14-core (20-thread) processor built for the mobile CPU market. It launched in Q1 2023 with a suggested retail price of $485. It is part of Intel's Core i7 lineup, which is based on the Raptor Lake-HX microarchitecture. The i7-13650HX is compatible with Intel BGA 1964 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 710 integrated graphics solution.

Memory and Cache

The Core i7-13650HX 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 i7-13650HX 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 2 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 i7-13650HX features 14 total cores which can process 20 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 14 cores consist of 6 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 2.6 GHz, and it can boost up to 4.9 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 i7-13650HX includes an integrated graphics solution called UHD Graphics 710. 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 i7-13650HX has the 38th best 3DMark 11 Performance Physics score among the 791 benchmarked CPUs in our database. It achieves 63.94% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X. Its 24,470 score and $485 launch price (MSRP) gives it a performance per dollar of 50.45. This is the 59th best in value for the 3DMark 11 Perf. Physics benchmark.
