AMD Ryzen 3 PRO 3300U

The AMD Ryzen 3 PRO 3300U is a mobile processor built on the Zen+ architecture, codenamed Picasso, and fabricated on a 12 nm process at GlobalFoundries. It integrates 4 cores and 4 threads, with a base clock of 2.10 GHz and a boost clock of 3.50 GHz, along with a Radeon Vega 6 integrated GPU. Its benchmark profile places it in the 38th percentile among all CPUs, with an average benchmark score of 1443, indicating a mid-to-low tier position in the broader processor landscape.

Benchmark Performance

The Ryzen 3 PRO 3300U delivers a multi-core Cinebench R23 score of 4992 and a single-core score of 704. In the older Cinebench R20 suite, it scores 2096 multi-core and 295 single-core, while in Cinebench R15 it reaches 503 multi-core and 70 single-core. These scores position the chip at a performance level that is closely matched by several rivals, with the delta between them being minimal.

Looking at the nearest rivals, the AMD Ryzen 3 2200GE holds an average score of 1444, which is just 0.1% higher than the 3300U’s 1443. The Intel Xeon E-2104G also sits at 1445, again 0.1% ahead. The Intel Core i7-4712HQ and AMD Opteron 6378 both average 1447, representing a 0.3% advantage over the 3300U. These deltas are effectively negligible, meaning the 3300U performs within a hair’s breadth of these four very different processors — a mobile APU, a desktop APU, a server Xeon, and an older high-core-count Opteron.

What stands out is the consistency of the gap. The 3300U is not decisively ahead of or behind any of these rivals; it is essentially tied with all four. In practical terms, benchmark results indicate that the 3300U will deliver performance indistinguishable from the 2200GE in most workloads, despite the latter being a desktop part. The Xeon E-2104G, a workstation-oriented chip, also falls into the same performance envelope. This suggests that the 3300U’s 12 nm Zen+ implementation is well-tuned for its power class, achieving parity with parts that have different thermal and power characteristics.

The percentile ranking of 38 tells a clearer story: the 3300U sits below the majority of all CPUs tracked, but it is not at the very bottom. The average benchmark score of 1443 is a useful aggregate, but it masks the split between single-thread and multi-thread behavior, which we will explore in a dedicated section. For now, the data shows a processor that competes in a tight cluster, where 0.3% differences are the norm.

Who Should Consider It

The Ryzen 3 PRO 3300U is a 15-watt mobile processor, which immediately suggests it is aimed at thin-and-light laptops rather than high-performance desktops. Given its 4-core, 4-thread configuration and its benchmark scores, it is best suited for everyday productivity tasks. Office applications, web browsing, and document editing will run comfortably within the performance envelope shown by the Cinebench results. The single-core score of 704 in R23 indicates that responsiveness in lightly-threaded apps is adequate, though not exceptional.

For content creation, the multi-core score of 4992 in Cinebench R23 suggests that light photo editing or casual video encoding is possible, but heavy rendering workloads will be slow. The 3300U is not a processor for professional 3D modeling or 4K video editing; those tasks require significantly higher multi-core throughput. Gamers should look toward the integrated Radeon Vega 6 graphics, but the CPU-side scores imply that modern 3D games will be limited to low settings and lower resolutions. The 38th percentile ranking reinforces the idea that this is a mainstream, not enthusiast, part.

In a mobile context, the 3300U makes sense for users who prioritize battery life and portability over raw performance. The 15-watt TDP class is typical for ultraportables, and the benchmark data shows that it can handle daily workloads without bottlenecking. Users who need to run virtual machines or compile code may find the 4-thread limit constraining, as multi-core scores beyond 5000 in R23 are often needed for smoother experiences in those scenarios. The close parity with the Ryzen 3 2200GE also means that users upgrading from that desktop APU will not notice a major shift in performance when moving to a 3300U-based laptop.

Platform and Compatibility

The Ryzen 3 PRO 3300U uses the AMD Socket FP5, a mobile-specific socket that is not interchangeable with desktop AM4 sockets. It supports DDR4 memory in a dual-channel configuration, which is standard for mobile APUs of this era. ECC memory is not supported, which is a limitation for users who require error-correcting memory for data integrity in scientific or financial workloads. PCIe Gen 3 is provided, which is sufficient for NVMe SSDs and modern discrete GPUs, though the integrated graphics will use some of those lanes.

The architecture is Zen+ (Picasso), which is a refinement of the original Zen design. The process node is 12 nm from GlobalFoundries, with 4,940 million transistors packed into a 210 mm² die. This is a relatively large die for a mobile chip, but it includes the Radeon Vega 6 graphics, which adds to the transistor count. The cache layout consists of 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. This is a modest cache configuration, and benchmark results suggest it does not hinder the chip significantly relative to its rivals.

The production status is listed as active, meaning the chip is still in manufacturing. The release date is April 2019, and it is part of the Ryzen 3 generation under the Picasso codename. The multiplier is not unlocked, so overclocking is not possible. The part number is YM330BC4T4MFG. For upgrade path considerations, the FP5 socket is typically soldered on mobile boards, so users cannot swap the processor. The platform is designed for the life of the laptop, not for future CPU upgrades. Memory support is limited to DDR4, and there is no indication of support for newer memory types.

Power and Thermals

The Ryzen 3 PRO 3300U has a TDP of 15 watts, which places it firmly in the ultra-low-power mobile segment. This TDP class is designed for thin and light laptops where thermal dissipation is limited and battery life is a priority. A 15-watt chip does not require an elaborate cooling solution; a standard laptop heatpipe and fan setup is sufficient. The 12 nm process from GlobalFoundries is not the most efficient node of its time, but the 15-watt limit forces the chip to stay within a constrained power envelope.

Benchmark results indicate that the chip sustains its performance within this power budget. The multi-core Cinebench R23 score of 4992 is respectable for a 15-watt part, showing that the power management is effective. In terms of cooling tier, a single heatpipe with a small fan is typical for this class. Passive cooling is unlikely, given the 4-core configuration, but the heat output is low enough that fan noise should be minimal under normal loads. The integrated Radeon Vega 6 GPU shares the same thermal budget, meaning sustained gaming will cause the CPU and GPU to compete for power, which may reduce sustained performance. The data does not provide specific thermal figures, but the 15-watt TDP implies that users should expect a warm but not hot chassis during extended use.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance is revealing. The Cinebench R23 single-core score is 704, while the multi-core score is 4992. This gives a multi-to-single ratio of roughly 7.1, which is close to the theoretical 4x scaling one would expect from 4 cores and 4 threads, but with diminishing returns due to thermal and power limits. In Cinebench R20, the single-core score is 295 and multi-core is 2096, yielding a ratio of about 7.1 as well, showing consistency across benchmark versions.

The single-thread scores are modest, placing the 3300U below many desktop parts. This means that applications which rely heavily on a single core — such as older games, certain database queries, or spreadsheet calculations — will not see impressive performance. The 704 single-core R23 score is indicative of a chip that is efficient but not fast in absolute terms. In contrast, the multi-core scores are more competitive relative to its rivals. The 4992 multi-core R23 score is within 0.3% of the Intel Core i7-4712HQ, which is a quad-core part from an older generation, showing that the 3300U holds its own in multi-threaded workloads.

For real-world use, this means that the 3300U will feel responsive in everyday tasks that are lightly threaded, but it will not excel in heavily threaded applications like video rendering or 3D simulation. The 4-thread limit is the primary constraint; a 4-core/8-thread part would offer better multi-thread scaling. The data shows a processor that is balanced for its class, with no extreme outlier in either direction. Users who primarily run single-threaded applications should not expect a dramatic experience, while those who can leverage all four cores will get near-linear scaling up to the thermal limit.
