AMD Ryzen 9 7950X3D vs AMD Athlon 64 FX-55

The AMD Ryzen 9 7950X3D is a 16-core (32-thread) processor built for the desktop CPU market. It launched in Q1 2023 with a suggested retail price of $699. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 4 microarchitecture. The 7950X3D is compatible with AMD Socket AM5 motherboards and is fabricated on TSMC's 5 nm manufacturing process. It features the Radeon Graphics integrated graphics solution.

Memory and Cache

The Ryzen 9 7950X3D supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 9 7950X3D 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 128 MB.

Cores and Clock Speeds

The Ryzen 9 7950X3D features 16 total cores which can process 32 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 4.2 GHz, and it can boost up to 5.7 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 Ryzen 9 7950X3D includes an integrated graphics solution called Radeon Graphics. 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 Ryzen 9 7950X3D has the 2nd best 3DMark 11 Performance Physics score among the 791 benchmarked CPUs in our database. It achieves 96.66% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X. Its 36,991 score and $699 launch price (MSRP) gives it a performance per dollar of 52.92. This is the 48th best in value for the 3DMark 11 Perf. Physics benchmark.

The AMD Athlon 64 FX-55 is an end-of-life 1-core (1-thread) processor built for the desktop CPU market. It launched in Q4 2004 with a suggested retail price of $827. It is part of AMD's Athlon 64 FX lineup, which is based on the ClawHammer microarchitecture. The 64 FX-55 is compatible with AMD Socket 939 motherboards and is fabricated on a 130 nm manufacturing process. It is bundled a Yes cooler.

Memory and Cache

The Athlon 64 FX-55 supports DDR1 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Athlon 64 FX-55 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 128 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, is larger but slower than the L1.

Cores and Clock Speeds

The Athlon 64 FX-55 is a single-core and single-threaded CPU, making it not capable of processing multiple computational tasks in parallel. The base clock speed of the CPU is 2.6 GHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.

Integrated Graphics

The Athlon 64 FX-55 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
