AMD Ryzen 9 5900X vs Intel Mobile Pentium III 700 LV

The AMD Ryzen 9 5900X is a 12-core (24-thread) processor built for the desktop CPU market. It launched in Q4 2020 with a suggested retail price of $549. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 3 microarchitecture. The 5900X is compatible with AMD Socket AM4 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The Ryzen 9 5900X supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 9 5900X 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 64 MB.

Cores and Clock Speeds

The Ryzen 9 5900X features 12 total cores which can process 24 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 4.8 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 5900X does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance & Value

The Ryzen 9 5900X has the 77th best 3DMark 11 Performance Physics score among the 768 benchmarked CPUs in our database. It achieves 54.99% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X. Its 21,043.5 score and $549 launch price (MSRP) gives it a performance per dollar of 38.33. This is the 96th best in value for the 3DMark 11 Perf. Physics benchmark.

The Intel Mobile Pentium III 700 LV is an end-of-life 1-core (1-thread) processor built for the mobile CPU market. It launched in Q1 2001 with a suggested retail price of $316. It is part of Intel's Pentium III lineup, which is based on the Coppermine microarchitecture. The Mobile III 700 LV is compatible with Intel Micro-BGA2 motherboards and is fabricated on Intel's 180 nm manufacturing process.

Memory and Cache

In terms of cache, the Mobile Pentium III 700 LV has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 32 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1.

Cores and Clock Speeds

The Mobile Pentium III 700 LV 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 700.0 MHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Mobile Pentium III 700 LV does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
