AMD Athlon PRO 200GE vs Intel Core i3-8121U Comparison

The Intel Core i3-8121U and AMD Athlon PRO 200GE are both dual-core, four-thread processors, but the benchmark data shows a decisive split: the Intel part wins all seven head-to-head comparisons, with single-core advantages reaching 23.3% and multi-core leads holding steady around 12%. The AMD part, despite a higher base clock and a larger die, trails in every measured workload. The data positions the i3-8121U as the stronger compute engine, while the Athlon PRO 200GE counters with integrated Radeon Vega 3 graphics and a desktop socket, making the choice depend on whether raw CPU throughput or platform flexibility matters more.

Where Each One Wins

The Intel Core i3-8121U wins every benchmark in the head-to-head set, making its use-case dominance unambiguous. In Geekbench single-core, the i3-8121U scores 1149 against the Athlon PRO 200GE’s 932, a 23.3% margin that indicates substantially better per-thread performance for lightly threaded tasks like web browsing, office productivity, and legacy application compatibility. The multi-core Geekbench result reinforces this: 2215 versus 1887, a 17.4% lead, showing that even when both threads are saturated, the Intel architecture extracts more work from the same core and thread count.

In Cinebench tests, the i3-8121U’s advantage is consistent but slightly narrower. Across Cinebench R15, R20, and R23 multi-core runs, the Intel part leads by 12.1% to 12.3%, with scores of 366 vs 326 (R15), 1527 vs 1362 (R20), and 3637 vs 3243 (R23). Single-core Cinebench R20 and R23 show 12.6% and 12.3% leads respectively. The pattern suggests that the i3-8121U’s performance edge is not workload-specific but fundamental to its design. The Athlon PRO 200GE has no benchmark wins, so there is no scenario in this data where it outperforms the Intel part. Its only unique advantage is the inclusion of Radeon Vega 3 integrated graphics, which the i3-8121U lacks entirely—meaning systems built on the AMD part can operate without a discrete GPU, a capability absent from the Intel side.

Architecture Differences

The two CPUs represent divergent design philosophies. The Intel Core i3-8121U is built on Cannon Lake, a 10 nm process from Intel, with a die size of 70.52 mm². The AMD Athlon PRO 200GE uses Zen architecture on GlobalFoundries’ 14 nm process, with a much larger die at 192 mm² and 4,800 million transistors. The Intel part has a base clock of 2.20 GHz and a boost clock of 3.20 GHz, while the AMD part runs at a fixed 3.20 GHz with no boost capability. The AMD’s higher base clock does not translate to performance wins, indicating that the Intel’s IPC (instructions per clock) efficiency from Cannon Lake overcomes the clock deficit.

Cache hierarchies differ significantly. The i3-8121U allocates 64 KB L1 and 256 KB L2 per core, with 4 MB shared L3. The Athlon PRO 200GE provides 96 KB L1 and 512 KB L2 per core, also with 4 MB shared L3. The AMD part has more per-core cache, but the Intel part’s superior single-core scores suggest that cache size alone is not the deciding factor. Memory bandwidth favors AMD: 42.7 GB/s versus Intel’s 38.4 GB/s, though both use dual-channel DDR4. Power and platform targets diverge sharply: the i3-8121U is a 15 W mobile part on Intel BGA 1440, while the Athlon PRO 200GE is a 35 W desktop/server part on AMD Socket AM4. The Intel part supports PCIe Gen 3 with 16 CPU lanes; the AMD part offers only 4 lanes. Integrated graphics are present only on the AMD (Radeon Vega 3), while the Intel data lists none.

FAQ

A: The Intel Core i3-8121U wins every single-core benchmark. In Geekbench single-core, it scores 1149 versus 932 for the AMD Athlon PRO 200GE, a 23.3% lead. Cinebench R20 and R23 single-core results show 12.6% and 12.3% advantages respectively.

Q: Are these processors comparable in multi-threaded workloads?

A: Both have 2 cores and 4 threads, but the Intel part leads in all multi-core tests. Cinebench R23 multi-core shows 3637 for Intel versus 3243 for AMD, a 12.1% margin. Geekbench multi-core shows a larger 17.4% gap (2215 vs 1887).

Q: Does the AMD processor have any feature the Intel lacks?

A: Yes. The AMD Athlon PRO 200GE includes integrated Radeon Vega 3 graphics, while the Intel Core i3-8121U has no integrated graphics listed. The AMD also supports a higher memory bandwidth of 42.7 GB/s versus 38.4 GB/s.

Q: What are the power consumption differences?

A: The Intel part has a TDP of 15 W, while the AMD part has a TDP of 35 W. This makes the Intel processor more suitable for power-constrained mobile designs, despite its lower performance ceiling in this comparison.

Q: Which platform offers more PCIe expansion?

A: The Intel Core i3-8121U provides 16 PCIe Gen 3 lanes (CPU only), whereas the AMD Athlon PRO 200GE provides only 4 lanes. This gives the Intel platform significantly more room for add-in cards.

Q: How do these CPUs rank against the broader market?

A: Both processors sit at the 34th percentile of all CPUs, with average benchmark scores of 1209 (Intel) and 1200 (AMD). Their nearest rivals include the Intel Xeon D-1520 (0% delta) for the Intel part and the Intel Core i5-3330 (0% delta) for the AMD part.

Head-to-Head Benchmarks

The largest single victory for the Intel Core i3-8121U comes in Geekbench single-core, where it scores 1149 against the AMD’s 932—a 23.3% delta. This is the standout result, indicating that for any single-threaded application, the Intel part is significantly faster. The Geekbench multi-core test also favors Intel heavily, with a 17.4% margin (2215 vs 1887), showing that the single-core advantage scales well into multi-threaded scenarios.

Cinebench results are more clustered but still uniformly Intel-favorable. The R20 single-core test shows a 12.6% lead (215 vs 191), the R23 single-core shows 12.3% (513 vs 457), and the R15 multi-core shows 12.3% (366 vs 326). The R20 multi-core and R23 multi-core both show 12.1% leads (1527 vs 1362 and 3637 vs 3243 respectively). The consistency of the ~12% margin across different Cinebench versions suggests a stable architectural efficiency difference rather than a workload-specific quirk. Notably, the AMD’s higher base clock (3.20 GHz vs 2.20 GHz) and larger cache per core (512 KB L2 vs 256 KB L2) do not help it close the gap, underscoring the Intel’s IPC advantage. The data shows zero wins for the AMD part across all seven tests.

The Verdict

The Intel Core i3-8121U is the clear performance winner in this comparison. It leads in every benchmark, with single-core advantages up to 23.3% and multi-core leads around 12-17%. For users prioritizing raw CPU throughput, particularly in single-threaded applications, the i3-8121U is the data-backed choice. Its 15 W TDP also makes it far more suitable for thin-and-light mobile devices, and its 16 PCIe lanes provide expansion headroom that the AMD part cannot match.

The AMD Athlon PRO 200GE, despite losing every benchmark, has a distinct role. Its Radeon Vega 3 integrated graphics mean a system can be built without a discrete GPU, a capability the Intel part entirely lacks. Its 35 W TDP and Socket AM4 platform target desktop or workstation builds where power efficiency is less critical than integrated graphics and a standard upgradeable socket. The higher memory bandwidth (42.7 GB/s vs 38.4 GB/s) and larger per-core caches are specifications that favor AMD, but they do not translate into benchmark wins. For anyone who needs graphics output without an add-in card, the Athlon PRO 200GE is the only viable option here. For everyone else, the benchmark data points unambiguously to the Intel Core i3-8121U.
