AMD Ryzen 7 6800U vs Intel Pentium 4 (2.53 GHz)

The AMD Ryzen 7 6800U is a 8-core (16-thread) processor built for the mobile CPU market. It launched in Q1 2022. It is part of AMD's Ryzen 7 lineup, which is based on the Zen 3+ microarchitecture. The 6800U is compatible with AMD Socket FP7 motherboards and is fabricated on TSMC's 6 nm manufacturing process. It features the Radeon 680M integrated graphics solution.

Memory and Cache

The Ryzen 7 6800U supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 7 6800U 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 16 MB.

Cores and Clock Speeds

The Ryzen 7 6800U 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 2.7 GHz, and it can boost up to 4.7 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 Ryzen 7 6800U includes an integrated graphics solution called Radeon 680M. 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 7 6800U has the 149th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 38.60% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

The Intel Pentium 4 (2.53 GHz) is an end-of-life 1-core (1-thread) processor built for the desktop CPU market. It launched in Q2 2002. It is part of Intel's Pentium 4 lineup, which is based on the Northwood microarchitecture. The 4 is compatible with Intel Socket 478 motherboards and is fabricated on Intel's 130 nm manufacturing process.

Memory and Cache

The Pentium 4 supports DDR1, DDR2 memory. In terms of cache, the Pentium 4 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 8 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 KB, is larger but slower than the L1.

Cores and Clock Speeds

The Pentium 4 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 2.5 GHz. 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 Pentium 4 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
