AMD Ryzen 3 3100U vs AMD Ryzen 5 5600XT Comparison

Head-to-Head Benchmarks

The recorded data shows a complete sweep for the AMD Ryzen 5 5600XT across all eleven shared benchmark tests. The Ryzen 3 3100U does not win a single comparison. The largest gaps appear in compute-heavy workloads, while the smallest relative gap shows up in single-thread performance.

In PassMark's integer math test, the Ryzen 5 5600XT scores 71,063 against 8,873 for the Ryzen 3 3100U, a delta of 87.5 percent in favor of the 5600XT. Floating point math follows a similar pattern: 40,537 versus 5,854, which is 85.6 percent ahead. The extended instructions test shows a delta of 87.9 percent, with the 5600XT posting 17,450 against 2,116. Prime number finding, often a proxy for raw integer throughput, shows 143 versus 18, a delta of 87.4 percent.

Data compression is another major differentiator. The 5600XT scores 257,118, while the 3100U manages 38,455, a delta of 85 percent. Encryption performance shows a delta of 87.6 percent: 15,944 versus 1,972. Random string sorting favors the 5600XT by 82.5 percent, with scores of 26,693 and 4,666 respectively.

Multithreaded performance, measured by PassMark's multithread test, shows the 5600XT at 22,283 versus 3,348 for the 3100U, a delta of 85 percent. The physics test narrows the gap slightly to 82.5 percent, with scores of 1,322 and 232. Single-thread performance shows the smallest delta of the group at 54.1 percent: the 5600XT scores 3,469, while the 3100U scores 1,592. This is still a decisive margin, but it indicates that the 5600XT's advantage is relatively smaller when only one core is active.

The average benchmark score tells the same story. The 5600XT records an average of 28,940 across its benchmark suite, placing it in the 81st percentile of all CPUs in the database. The 3100U averages 6,247, which puts it in the 62nd percentile. The nearest rivals for the 5600XT in the database are Intel mobile processors: the Core i9-13900H (average 28,886, delta 0.2 percent), Core i5-12600H (average 28,882, delta 0.2 percent), and Core i7-12650H (average 28,815, delta 0.4 percent). The Intel Core Ultra 5 135H sits slightly higher at 29,093, a delta of -0.5 percent. The 3100U's nearest rivals are all high-core-count desktop and server parts: the Threadripper 1950X (6,231, delta 0.3 percent), EPYC 7272 (6,186, delta 1 percent), Core i9-10920X (6,347, delta -1.6 percent), and Core i9-7940X (6,147, delta 1.6 percent). The 3100U's average sits close to these parts, within roughly 2 percent, which is notable given its much lower core count.

The Verdict

The benchmark data is unambiguous. The Ryzen 5 5600XT outperforms the Ryzen 3 3100U in every measured category, often by margins exceeding 80 percent. The smallest gap, single-thread performance, still favors the 5600XT by 54.1 percent. For any workload represented in the database, the 5600XT is the stronger processor.

The Ryzen 3 3100U remains competitive only in the sense that its average benchmark score aligns with much larger desktop and server chips from an older generation. Its 62nd percentile ranking places it above a substantial portion of the database, but those nearest rivals are all processors with far more cores. This suggests the 3100U's strength lies in efficiency per core rather than raw throughput.

The 5600XT, with an 81st percentile ranking, sits among modern mobile and desktop processors. Its nearest rivals are all Intel H-series mobile chips, which indicates that its performance profile matches high-end laptops from Intel's lineup. The delta between those rivals and the 5600XT is small, within 0.5 percent, so the 5600XT is effectively level with them in average score.

For users selecting between these two, the choice depends on workload and platform. The 5600XT is a desktop part with a 65 TDP and an AM4 socket. The 3100U is a mobile part with a 15 TDP and an FP5 socket. The data shows that the 5600XT delivers dramatically higher performance, but the 3100U consumes far less power and targets a different form factor. The database does not include power efficiency metrics, so any comparison of performance per watt would require additional data.

Architecture Differences

The two processors come from different architectural eras. The Ryzen 3 3100U uses the Picasso codename, which is based on the Zen+ microarchitecture. The Ryzen 5 5600XT uses the Vermeer codename, based on Zen 3. The generation field confirms this split: the 3100U is listed as "Ryzen 3 (Zen+ (Picasso))", while the 5600XT is "Ryzen 5 (Zen 3 (Vermeer))".

The process node differs substantially. The 3100U is built on a 12 nm process at GlobalFoundries. The 5600XT uses a 7 nm process at TSMC. The transistor counts go in opposite directions relative to node size: the 3100U has 4,940 million transistors on a 210 mm² die, while the 5600XT has 4,150 million transistors on a 74 mm² die. The 5600XT packs nearly as many transistors into roughly one-third of the silicon area, which reflects the denser 7 nm process.

Cache architecture also diverges. The 3100U has 96 KB of L1 per core and 512 KB of L2 per core, with 4 MB of shared L3. The 5600XT has 64 KB of L1 per core and 512 KB of L2 per core, but its shared L3 is 32 MB. The 5600XT's L3 cache is eight times larger, which is a significant factor in workloads that benefit from shared data access across cores.

The 3100U includes integrated graphics: Radeon Vega 8. The 5600XT has no integrated graphics, listed as "N/A". This means the 3100U can drive a display without a discrete GPU, while the 5600XT requires a separate graphics card. The 3100U also supports ECC memory, but the database lists it as false; the 5600XT lists ECC support as true.

The 3100U uses PCIe Gen 3, while the 5600XT uses Gen 4 with 20 lanes (CPU only). The 5600XT is also multiplier unlocked, meaning overclocking is possible, while the 3100U is locked. The 3100U's memory bandwidth is 38.4 GB/s, while the 5600XT reaches 51.2 GB/s, both over dual-channel DDR4.

The 5600XT has three cores and six threads more than the 3100U, which is a direct result of the architectural generation jump and the desktop vs. mobile positioning. The 3100U is a 2-core, 2-thread part; the 5600XT is a 6-core, 12-thread part.

Where Each One Wins

The Ryzen 5 5600XT wins every benchmark in the database. There is no recorded test where the Ryzen 3 3100U comes out ahead. The 5600XT's largest advantages are in extended instructions (87.9 percent), encryption (87.6 percent), and integer math (87.5 percent). Its smallest advantage is in single-thread performance at 54.1 percent.

The Ryzen 3 3100U's only meaningful strengths are contextual. Its 15 watt TDP makes it suitable for thin-and-light mobile devices, while the 5600XT's 65 watt TDP targets desktop systems with active cooling. The 3100U includes integrated graphics, so it can operate without a discrete GPU. The 5600XT requires a separate graphics solution. The 3100U also uses the older and smaller FP5 socket, which ties it to a mobile motherboard ecosystem.

For workloads that rely on single-core responsiveness, such as light office tasks or basic web browsing, the 3100U's 3.20 GHz boost clock and 1,592 single-thread score are functional, but the 5600XT still delivers a 54.1 percent higher score. For any compute-intensive task, including data compression, encryption, or physics simulation, the 5600XT is the clear choice based on the recorded deltas.

The 3100U's nearest rivals in the database are older high-core-count parts like the Threadripper 1950X and EPYC 7272, with deltas under 2 percent. This indicates that the 3100U, despite having only 2 cores, achieves a comparable average score to 16-core and 8-core server processors from an earlier generation. That positioning suggests the 3100U is best understood as an efficient, low-power mobile processor that punches above its core count in average score, but it cannot compete with a modern 6-core desktop chip like the 5600XT.

The 5600XT's nearest rivals are Intel H-series mobile processors, with deltas within 0.5 percent. This places the 5600XT in a performance tier that matches high-end laptop chips, but its desktop socket and 65 watt TDP mean it is not directly comparable to those mobile parts in system design. The data shows the 5600XT is the superior processor in every benchmark category, so any use case that requires maximum throughput, whether single-threaded or multithreaded, should select the 5600XT. The 3100U remains viable only for low-power, integrated-graphics mobile systems where the 5600XT cannot physically fit.
