CPU Comparison

The AMD Opteron 4334 and Intel Core i3-8145UE are an unusual pair: a six-core server chip from 2012 and a dual-core mobile part from 2018. Their average benchmark scores are nearly identical, 1155 for the AMD versus 1154 for the Intel, and their Cinebench results are so close that the differences are statistically negligible. The data shows the Opteron 4334 wins all five head-to-head tests, but by margins of 0.0% to 0.3%. The real distinction is not in raw performance but in platform characteristics: the Opteron is a 95W Socket C32 server processor, while the i3-8145UE is a 15W mobile chip with integrated graphics and a 38.4 GB/s dual-channel DDR4 memory bus. Your choice depends entirely on whether you need a low-power embedded solution with modern I/O or a legacy server platform with more physical cores.

The Verdict

Choose the AMD Opteron 4334 if you are building or upgrading a legacy server/workstation on Socket C32. It offers six physical cores and a 3.10 GHz base clock, boosting to 3.50 GHz. The data shows it edges out the i3-8145UE in every Cinebench test, including a 0.3% lead in Cinebench R15 multicore (338 vs 337) and a 0.1% lead in Cinebench R23 multicore (3356 vs 3354). Its 33rd percentile ranking puts it in the same performance class as the Intel Core i5-4430, which scores 1149 on average, just 0.5% behind. If you need a drop-in replacement for an older Opteron 4000 series board, this is the practical pick.

Choose the Intel Core i3-8145UE if you prioritize power efficiency, integrated graphics, and modern connectivity. Its 15W TDP is drastically lower than the Opteron's 95W, making it suitable for fanless or compact mobile designs. It includes UHD Graphics 620, which the Opteron lacks entirely, plus PCIe Gen 3 with 16 lanes and dual-channel DDR4 memory at 38.4 GB/s. Benchmark results show it matches the Opteron in single-core Cinebench R20 and R23 (both 198 and 473, respectively), so for lightly threaded workloads, the Intel part is effectively equal while consuming far less power. Its active production status also means it remains available for new designs.

For most modern users, the i3-8145UE is the more sensible recommendation. The Opteron's six cores do not translate into meaningful benchmark advantages, the largest delta is 0.3%, and its lack of integrated graphics, ECC support, and modern memory standards make it a niche part. The i3-8145UE's nearest rival is the AMD Ryzen Embedded R2312, which scores 1156 on average, a 0.2% delta. That places the Intel chip in a competitive embedded market segment.

Architecture Differences

The Opteron 4334 uses AMD's Piledriver architecture, codenamed Seoul, built on a 32 nm process. It packs 1,200 million transistors into a 315 mm² die. The i3-8145UE uses Intel's Whiskey Lake architecture (Whiskey Lake-U) on a 10 nm process with Intel as the foundry. This process advantage explains how the Intel chip achieves comparable performance with far fewer resources.

Core counts differ significantly: the Opteron has 6 cores and 6 threads, while the i3-8145UE has 2 cores and 4 threads thanks to Hyper-Threading. Cache layouts are also distinct. The Opteron has 288 KB of L1, 6 MB of L2, and 8 MB of shared L3. The Intel chip has 64 KB L1 per core, 256 KB L2 per core, and 4 MB of shared L3. Despite the Intel part having less total cache, its per-core allocation is generous.

Memory support diverges sharply. The Opteron uses DDR3, while the i3-8145UE uses DDR4 with a dual-channel bus and 38.4 GB/s of bandwidth. The Intel chip supports PCIe Gen 3 with 16 lanes (CPU only) and includes integrated UHD Graphics 620. The Opteron has no integrated graphics and no listed PCIe capability. Neither chip supports ECC memory. The Opteron is unlocked? No, both have locked multipliers.

Where Each One Wins

The Opteron 4334 wins all five head-to-head benchmarks, but the margins are razor-thin. Its largest victory is 0.3% in Cinebench R15 multicore (338 vs 337). In Cinebench R20 multicore, it leads 1409 to 1408 (0.1%). In Cinebench R23 multicore, it wins 3356 to 3354 (0.1%). These results suggest the Opteron has a slight edge in multi-threaded rendering, likely due to its six physical cores versus the Intel's two cores and four threads.

The i3-8145UE wins on platform features rather than benchmark scores. Its 15W TDP versus 95W makes it the clear choice for thermally constrained environments. It has integrated graphics (UHD Graphics 620), which the Opteron lacks, a decisive factor for systems without a discrete GPU. Its DDR4 memory support and 38.4 GB/s bandwidth are modern standards, while the Opteron is limited to DDR3. The Intel chip's PCIe Gen 3 with 16 lanes provides contemporary connectivity options.

Single-core performance is a draw. Both score exactly 198 in Cinebench R20 single-core and exactly 473 in Cinebench R23 single-core. The head-to-head lists the Opteron as the winner with 0% delta, but that is a tie in practical terms. For single-threaded workloads, the two chips are interchangeable.

FAQ

Q: Which CPU has better multi-threaded performance?

A: The AMD Opteron 4334, according to the data. It wins all three multi-core tests: Cinebench R15 (338 vs 337), R20 (1409 vs 1408), and R23 (3356 vs 3354). However, the largest margin is only 0.3%, so the difference is minimal.

Q: Is the Intel Core i3-8145UE more power-efficient?

A: Yes. The i3-8145UE has a 15W TDP, while the Opteron 4334 has a 95W TDP. This is a substantial difference, making the Intel chip suitable for mobile or low-power designs.

Q: Does either CPU support ECC memory?

A: No. Both the Opteron 4334 and the i3-8145UE have ECC memory support listed as false.

Q: Which CPU has integrated graphics?

A: Only the Intel Core i3-8145UE, which includes UHD Graphics 620. The AMD Opteron 4334 has no integrated graphics, requiring a separate GPU for display output.

Q: How do these CPUs compare to other rivals?

A: The Opteron 4334's closest rival is the AMD Ryzen Embedded R2312, which scores 1156 on average (0.1% higher). The i3-8145UE's nearest rival is the AMD Opteron 4334 itself (1155, 0.1% higher), followed by the Ryzen Embedded R2312 (1156, 0.2% higher). Both also trail the Intel Core i5-4430 by 0.5% and 0.4%, respectively.

Q: What is the release date difference?

A: The Opteron 4334 was released on 2012-12-03, while the i3-8145UE was released on 2018-09-30. The Intel chip is nearly six years newer.

Head-to-Head Benchmarks

The data shows a remarkably consistent pattern: the Opteron 4334 wins every test, but by margins that would be lost in run-to-run variance. In Cinebench R15 multicore, the Opteron scores 338 against 337 for the i3-8145UE, a 0.3% lead. This is the largest delta between the two chips in any test.

Moving to Cinebench R20, the multicore result shows 1409 versus 1408, a 0.1% difference. The single-core test is a perfect tie at 198 points, with the Opteron listed as the winner due to a 0% delta. Cinebench R23 follows the same pattern: multicore is 3356 versus 3354 (0.1%), and single-core is 473 versus 473 (0%).

The average benchmark scores reinforce this picture. The Opteron 4334 averages 1155, while the i3-8145UE averages 1154. Both sit at the 33rd percentile of all CPUs. Their nearest rival, the AMD Ryzen Embedded R2312, scores 1156 on average, placing these two chips within 0.2% of that part as well.

For practical purposes, these chips are performance equals. The Opteron's six cores do not produce a meaningful advantage in Cinebench, likely because the i3-8145UE's higher boost clock (3.90 GHz versus 3.50 GHz) and newer architecture compensate for its two-core disadvantage. If benchmark scores are your only criterion, flip a coin.
