AMD Ryzen 7 4800U

The AMD Ryzen 7 4800U is a mobile processor built on the Zen 2 architecture (Renoir) at TSMC's 7 nm process, featuring 8 cores and 16 threads with a base clock of 1.80 GHz and a boost clock of 4.20 GHz. It carries a 15 W TDP, integrates Radeon RX Vega 8 graphics, and sits in the 60th percentile of all CPUs in the benchmark database, with an average benchmark score of 3934 across the recorded tests. This is a chip designed for thin-and-light laptops that still need substantial multi-threaded throughput.

Who Should Consider It

The 4800U’s benchmark profile points to a specific set of workloads. In Cinebench R23, it scores 14095 in multi-core and 1989 in single-core; in Geekbench, it reaches 5609 multi-core and 1401 single-core. The multi-core results are strong for a 15 W part, meaning users who regularly run parallelizable tasks—such as video encoding, 3D rendering, or code compilation—will find this chip capable of handling moderate workloads without a dedicated workstation. The single-core scores are less impressive, so tasks that depend on one thread, like many older games or lightly threaded office macros, will not see exceptional responsiveness.

For gaming, the integrated Radeon RX Vega 8 GPU provides a baseline, but the CPU’s modest single-core performance and 15 W envelope suggest it is better suited for casual titles or esports at lower settings rather than AAA gaming at high frame rates. Office productivity, web browsing, and document editing are well within reach, though the multi-threaded headroom means the 4800U will also handle background tasks like antivirus scans or cloud syncs without choking. It is a good fit for a portable daily driver where battery life and thermals matter more than peak burst speed.

Power and Thermals

The 4800U has a TDP of 15 W, placing it in the low-power mobile segment. This TDP class implies a thin-and-light cooling solution—likely a small fan or passive heat pipe design—since the processor is not intended to sustain high clock rates for long periods. The 7 nm process node and 9,800 million transistors on a 156 mm² die help keep power density manageable, but the boost clock of 4.20 GHz will only be reachable in short bursts before thermal or power limits pull it back. The data shows a clear trade-off: multi-core performance is respectable because the chip can use all 8 cores at moderate clocks, but sustained all-core loads will likely throttle under the 15 W cap. Users should expect a chassis with adequate ventilation, but not a gaming-laptop cooling solution.

Platform and Compatibility

The 4800U uses AMD Socket FP6, which is a BGA (ball-grid array) package typical for mobile processors—meaning it is soldered to the motherboard and not upgradeable. Memory support includes DDR4 and LPDDR4 in a dual-channel configuration, with a theoretical memory bandwidth of 51.2 GB/s. ECC memory is not supported, so this is not aimed at error-correcting workstation environments. The chip provides PCIe Gen 3 connectivity, which is one generation behind the PCIe Gen 4 found in some newer platforms, but still sufficient for NVMe SSDs and discrete GPUs of that era. Integrated graphics are handled by the Radeon RX Vega 8, so no separate GPU is required for basic display output. The production status is listed as “Active,” and the release date is January 5, 2020, indicating it is a mature product that may still be found in current budget laptops. The part number is 100-000000082, and the multiplier is locked, so overclocking is not an option.

Benchmark Performance

The 4800U’s average benchmark score of 3934 places it in the 60th percentile of all CPUs in the database. Its nearest rivals are extremely close in overall performance: the AMD Ryzen 5 PRO 4650G scores 3927, which is 0.2% lower; the Intel Core i7-11700T scores 3948, which is 0.3% higher; the Intel Core i5-11500H scores 3919, 0.4% lower; and the Intel Core i5-12500TE scores 3917, also 0.4% lower. These deltas are within a fraction of a percent, meaning the 4800U is statistically tied with all four competitors in aggregate performance.

Looking at specific workloads, Cinebench R23 multi-core yields 14095 points, while single-core yields 1989 points. The multi-core result is roughly 7.1 times the single-core figure, which is a strong scaling ratio for 8 cores and 16 threads, though not linear due to power and thermal limits. In Geekbench, the multi-core score of 5609 is exactly 4.0 times the single-core score of 1401, again showing effective parallelization. These numbers suggest the 4800U can hold its own against the listed rivals in mixed workloads, but it will not pull ahead by a meaningful margin in any single test.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance reveals the 4800U’s design priorities. With a Cinebench R23 single-core score of 1989 and a multi-core score of 14095, the chip demonstrates that it can scale across all cores, but the single-thread result is modest compared to higher-clocked desktop parts. In Geekbench, the single-core score of 1401 against a multi-core of 5609 reinforces this pattern: the processor is balanced but not exceptional in lightly threaded tasks.

For real-world use, this means applications that are well-optimized for multiple threads—such as video editing, 3D modeling, or running virtual machines—will see a clear benefit from the 8-core/16-thread configuration. Conversely, software that relies on a single thread, like many legacy applications or certain game engines, will not leverage the full potential of the chip. The low TDP further compounds this: single-core boost clocks are limited to 4.20 GHz, but that boost is only sustainable for short periods. The data implies that the 4800U is best suited for parallel workloads where the 15 W envelope can be spread across many cores at lower frequencies, rather than for bursty single-threaded tasks.

How It Compares

AMD Ryzen 5 PRO 4650G — This rival has an average score of 3927, which is 0.2% lower than the 4800U’s 3934. The delta is negligible, so in aggregate performance they are effectively identical. The 4650G is a desktop APU, but the mobile 4800U matches it in overall benchmarks, suggesting that the 15 W power limit does not cripple multi-core throughput compared to a higher-TDP desktop part in this specific comparison.

Intel Core i7-11700T — The i7-11700T scores 3948, which is 0.3% higher than the 4800U. This is the only rival that edges out the 4800U, but the margin is so small that it would be imperceptible in everyday use. The i7-11700T is a low-power desktop chip, so the 4800U’s mobile 15 W design manages to stay within 0.3% of a desktop part, which speaks to the efficiency of Zen 2.

Intel Core i5-11500H — With a score of 3919, the i5-11500H is 0.4% lower than the 4800U. The i5-11500H is a higher-TDP mobile H-series processor, yet the 4800U still edges it out in aggregate benchmarks. This suggests that the 4800U’s extra two cores (8 vs. 6) help offset the lower power budget.

Intel Core i5-12500TE — The i5-12500TE scores 3917, also 0.4% lower than the 4800U. This is a 12th-gen Alder Lake low-power part, but the 4800U’s Zen 2 architecture holds its ground. The delta is within noise, so users should base their choice on platform features (like PCIe generation or memory support) rather than raw performance.
