AMD Opteron 6212 vs Intel Core i5-3570S Comparison

The Intel Core i5-3570S and the AMD Opteron 6212 represent two fundamentally different approaches to computing, one aimed at the desktop and the other at the server room. Despite the Opteron’s higher core count, the benchmark data consistently shows the Intel processor taking a decisive lead across every single test in the comparison. The data paints a clear picture of a processor that wins on efficiency and per-core strength versus a server chip that, while having more cores, cannot translate that hardware into superior benchmark performance.

Head-to-Head Benchmarks

The head-to-head results are unambiguous, with the Intel Core i5-3570S winning all five recorded benchmark comparisons. The most dominant margin for the Intel chip comes in the single-core tests, where it holds a consistent advantage of just over 18 percent. Specifically, in Cinebench R20 single-core, the i5-3570S scores 236 against the Opteron 6212's 199, a delta of 18.6 percent. This pattern repeats in Cinebench R23 single-core, with scores of 563 and 476 respectively, a difference of 18.3 percent. These results indicate that for tasks relying on a single thread, the Intel processor’s higher clock speeds and architectural efficiency provide a significant edge.

The multi-core results are equally one-sided, though the margins are slightly smaller. The Intel Core i5-3570S leads by 18.2 percent across all three Cinebench multi-core tests. In Cinebench R15 multi-core, it scores 402 versus the Opteron’s 340. The gap widens in raw points in newer tests: in Cinebench R20 multi-core, the i5-3570S scores 1676 against 1418, and in Cinebench R23 multi-core, it reaches 3991 versus 3377. It is notable that even with half the physical cores (4 vs 8), the Intel processor manages to outpace the AMD chip in workloads that should theoretically favor more cores. This strongly suggests that the Opteron 6212's Bulldozer architecture does not scale effectively in these specific benchmarks.

The aggregate data reinforces this narrative. The Intel Core i5-3570S has an average benchmark score of 1169, while the AMD Opteron 6212 sits slightly lower at 1162. While the difference in average score is small (0.6 percent in favor of the Intel chip), the consistency of the head-to-head wins is what truly matters. Furthermore, the nearest rivals for each chip are telling. The i5-3570S is closely matched with the Intel Core i7-2960XM (0 percent delta) and the Intel Core i5-3450 (0.2 percent delta). The Opteron 6212, on the other hand, is found alongside the AMD Ryzen Embedded R2312 (0.5 percent delta) and the same Intel Core i5-3450, but this time trailing it by 0.4 percent. The data shows that the i5-3570S is effectively on par with other Intel mainstream chips, while the Opteron is slightly behind the same competition.

Architecture Differences

The architectural divide between these two processors is vast and explains the benchmark outcomes. The Intel Core i5-3570S is built on the Ivy Bridge architecture, which uses a 22 nm process node and is fabricated by Intel itself. Its die size is listed as 133 mm². In contrast, the AMD Opteron 6212 is based on the Bulldozer architecture, codenamed Interlagos, and uses a larger 32 nm process node from GlobalFoundries. The Opteron’s die is significantly larger, listed as 2x 315 mm², and it contains 2,400 million transistors, while the Intel chip’s transistor count is not listed.

The core and cache configurations are fundamentally different. The Intel i5-3570S has 4 cores and 4 threads, with a cache hierarchy of 64 KB of L1 per core and 256 KB of L2 per core, plus a shared 6 MB L3 cache. The AMD Opteron 6212 has 8 cores and 8 threads, but its cache is organized differently: it has 768 KB of L1 cache total, 2 MB of L2 per module, and 8 MB of L3 per die. This highlights the modular design of Bulldozer, where pairs of cores share resources. The Intel chip’s cache structure is simpler and more direct per-core.

Clock speeds also differ, which is a key factor in the single-core performance gap. The Intel i5-3570S has a base clock of 3.10 GHz and a boost clock of 3.80 GHz. The AMD Opteron 6212 has a lower base clock of 2.60 GHz and a boost clock of 3.20 GHz. This 600 MHz to 600 MHz difference in base and boost clocks, respectively, gives the Intel chip a raw speed advantage that its more efficient Ivy Bridge architecture can exploit. The platforms also differ entirely: the Intel chip uses an Intel Socket 1155 with PCIe Gen 3 (16 lanes, CPU only), while the Opteron uses an AMD Socket G34 with PCIe Gen 2.

Where Each One Wins

Based on the data, the Intel Core i5-3570S is the clear winner in every category of tested workload. It wins in all multi-core scenarios, which is surprising given the Opteron’s 8-core count. This suggests that for applications like Cinebench, which can utilize multiple threads, the Intel chip’s superior per-core performance and efficient cache design are more valuable than raw core count. The i5-3570S also dominates in single-core tasks, making it the better choice for legacy software or applications that are not well-optimized for multi-threading.

The AMD Opteron 6212, with zero benchmark wins, does not have a single tested scenario where it outperforms the Intel chip. However, its hardware profile suggests where it might be intended to be used. Its strengths lie outside the benchmark suite provided. It supports ECC memory, which the Intel chip does not, and it has a quad-channel memory bus with a stated memory bandwidth of 51.2 GB/s, whereas the Intel chip only supports dual-channel memory with no listed bandwidth figure. This points to a server-oriented design where data integrity and memory throughput are critical for large-scale virtualization or database workloads, even if its raw computational performance in Cinebench is lower. The Opteron also has a higher core count, which could be beneficial for highly parallel server tasks that are not represented in these specific tests.

The Verdict

The data is unequivocal: the Intel Core i5-3570S is the superior processor in terms of raw computational performance as measured by the Cinebench suite. It wins every single head-to-head benchmark and holds a higher average score. Its lower TDP of 65 W versus the Opteron’s 115 W, combined with its higher clock speeds and more modern 22 nm process, demonstrates a far more energy-efficient design. For any user whose primary concern is the types of multi-threaded and single-threaded workloads represented in these tests, the Intel Core i5-3570S is the clear choice.

The AMD Opteron 6212, despite its 8 cores, fails to compete in these benchmarks. However, its specification sheet tells a different story about its intended purpose. The inclusion of ECC memory support, a quad-channel memory bus with a high bandwidth figure, and a server-class socket (G34) indicate it was designed for reliability and memory throughput in enterprise environments. The data suggests that while it loses in general compute tests, it could be the more appropriate part for server workloads where memory integrity and bandwidth are paramount, and where its specific architectural strengths might be better utilized. For a standard desktop or workstation context based on the provided benchmark data, the Intel chip is the definitive winner.
