AMD Opteron 6212 vs Intel Core i3-8145UE Comparison

Head-to-Head Benchmarks

The benchmark data presents an unusually tight contest between the AMD Opteron 6212 and the Intel Core i3-8145UE. Across all five Cinebench comparisons, the AMD processor wins every single test, but the margins are remarkably narrow. The largest gap appears in Cinebench R15 multicore, where the Opteron 6212 scores 340 against the Core i3-8145UE's 337, a delta of just 0.9%. That is the widest margin in the entire head-to-head set.

The pattern continues in Cinebench R20 multicore, with the Opteron 6212 posting 1418 versus 1408 for the Intel part, a 0.7% advantage. Single-core results tell the same story: the AMD chip leads 199 to 198 in Cinebench R20 single-core (0.5% delta) and 476 to 473 in Cinebench R23 single-core (0.6% delta). The Cinebench R23 multicore run shows 3377 for the Opteron against 3354 for the Core i3, another 0.7% edge.

What makes these numbers striking is the underlying hardware disparity. The Opteron 6212 is an 8-core, 8-thread server processor with a 115-watt TDP, while the Core i3-8145UE is a 2-core, 4-thread mobile chip rated at just 15 watts. Despite having four times the physical cores and nearly eight times the power envelope, the Opteron only manages to edge ahead by less than one percent in every test. The Core i3's higher boost clock of 3.90 GHz against the Opteron's 3.20 GHz clearly helps close the gap, but the data shows the older AMD architecture still holds a slight edge across the board.

The wins are consistent but not decisive. The Opteron 6212 wins all five head-to-head comparisons, yet the largest single delta is under one percent. In practical terms, these two processors deliver nearly identical Cinebench performance, which is remarkable given their completely different design goals and market positions.

Architecture Differences

The architectural divide between these two processors is substantial. The AMD Opteron 6212 uses the Bulldozer architecture under the codename Interlagos, built on a 32 nm process at GlobalFoundries with 2,400 million transistors spread across a dual-die design measuring 2x 315 mm². It belongs to the Opteron 6000 series and targets server and workstation workloads. The Intel Core i3-8145UE, by contrast, uses the Whiskey Lake architecture (Whiskey Lake-U codename), fabricated on Intel's 10 nm process, and is designed for mobile computing.

Cache configurations differ fundamentally. The Opteron 6212 packs 768 KB of L1 cache, 2 MB of L2 per module, and 8 MB of L3 per die. The Core i3-8145UE has 64 KB of L1 per core, 256 KB of L2 per core, and 4 MB of shared L3. The Opteron's dual-die layout means its L3 is distributed across two dies, while the Intel part uses a single shared pool.

Memory support marks another clear divergence. The Opteron 6212 runs DDR3 with a quad-channel memory bus delivering 51.2 GB/s of bandwidth, and it supports ECC memory. The Core i3-8145UE runs DDR4 with a dual-channel bus providing 38.4 GB/s and no ECC support. The Opteron's bandwidth advantage is significant on paper, though the benchmark data suggests it does not translate into a meaningful performance lead in Cinebench workloads.

PCIe generations also differ: the Opteron uses Gen 2, while the Core i3 supports Gen 3 with 16 lanes from the CPU. The Intel part includes integrated UHD Graphics 620, whereas the Opteron has no integrated graphics at all. The Opteron uses AMD Socket G34, while the Core i3 is soldered to Intel BGA 1528. The production statuses reflect their ages: the Opteron is end-of-life with a release date in November 2011, while the Core i3 remains active with a September 2018 release.

Specification Differences

The two processors differ in nearly every specification category. The Opteron 6212 uses the Bulldozer architecture with the Interlagos codename, while the Core i3-8145UE uses Whiskey Lake with the Whiskey Lake-U codename. The Opteron is built on a 32 nm process at GlobalFoundries with 2,400 million transistors and a die size of 2x 315 mm². The Core i3 uses Intel's 10 nm process, with transistor count and die size not listed.

Core and thread counts diverge sharply: 8 cores and 8 threads for the Opteron versus 2 cores and 4 threads for the Core i3. Base clocks are 2.60 GHz for the AMD part and 2.20 GHz for the Intel part, but boost clocks reverse the order: 3.20 GHz for the Opteron and 3.90 GHz for the Core i3. TDP ratings are dramatically different at 115 watts versus 15 watts.

Cache hierarchies are built on different philosophies. The Opteron has 768 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. The Core i3 has 64 KB of L1 per core, 256 KB of L2 per core, and 4 MB of shared L3. Memory support sees the Opteron on DDR3 with quad-channel access and 51.2 GB/s bandwidth, while the Core i3 uses DDR4 with dual-channel access and 38.4 GB/s. ECC support exists only on the Opteron.

Sockets and PCIe generations also differ: AMD Socket G34 with Gen 2 for the Opteron, Intel BGA 1528 with Gen 3 for the Core i3. The Opteron has no integrated graphics, while the Core i3 includes UHD Graphics 620. Market segments are server/workstation for the AMD part and mobile for the Intel part. Production statuses are end-of-life for the Opteron and active for the Core i3. The Opteron's launch MSRP was $266; the Core i3 has no listed launch MSRP.

The Verdict

The data presents a clear but nuanced picture. The AMD Opteron 6212 wins every benchmark in the head-to-head comparison, but the margins are so small that they fall within the range of run-to-run variance. A 0.9% lead in Cinebench R15 multicore and a 0.5% lead in Cinebench R20 single-core are not meaningful performance advantages in real-world terms. Both processors land at the 33rd percentile among all CPUs, and their average benchmark scores are nearly identical: 1162 for the Opteron and 1154 for the Core i3.

Looking at nearest rivals, the Opteron 6212 sits within 0.6% of the Intel Core i5-3450 (1166), the AMD Ryzen Embedded R2312 (1156), the AMD Opteron 6220 (1168), and the Intel Core i5-3570S (1169). The Core i3-8145UE similarly sits within 0.6% of the AMD Opteron 4334 (1155), the Ryzen Embedded R2312 (1156), the Intel Core i5-4430 (1149), and the Intel Core i7-3612QE (1147). In other words, both processors occupy the same performance tier, surrounded by the same class of rivals.

The verdict depends on context. For raw Cinebench performance, the Opteron 6212 is nominally the winner, but the margin is negligible. For power efficiency, the Core i3-8145UE is the obvious choice, delivering nearly identical scores at a fraction of the power draw. For server workloads requiring ECC memory and quad-channel bandwidth, the Opteron has structural advantages that benchmarks here do not capture. For mobile deployments with integrated graphics needs, the Core i3 is the only viable option.

Where Each One Wins

The AMD Opteron 6212 wins in every benchmark measured, but its victories are symbolic rather than substantial. It leads by 0.9% in Cinebench R15 multicore, 0.7% in Cinebench R20 multicore, 0.5% in Cinebench R20 single-core, 0.7% in Cinebench R23 multicore, and 0.6% in Cinebench R23 single-core. If the selection criterion is purely benchmark score, the Opteron takes the win across the board.

The Intel Core i3-8145UE wins in power efficiency and platform characteristics. Its 15-watt TDP is dramatically lower than the Opteron's 115 watts, making it suitable for thermally constrained environments. It includes integrated UHD Graphics 620, eliminating the need for a discrete GPU. It supports DDR4 memory and PCIe Gen 3, offering a more modern platform foundation. Its 3.90 GHz boost clock provides a higher single-thread ceiling, even if the benchmark results do not reflect an actual win.

Structurally, the Opteron 6212 wins for ECC memory support, quad-channel bandwidth at 51.2 GB/s, and a larger L3 cache distribution across two dies. The Core i3-8145UE wins for its 10 nm process, active production status, and mobile form factor with BGA 1528 packaging. For server deployments requiring data integrity and high memory throughput, the Opteron is the choice. For embedded or mobile systems prioritizing power and integration, the Core i3 is the choice. For pure Cinebench performance, the Opteron wins all five tests, but the data suggests either processor will deliver essentially the same experience.
