AMD Opteron 6328 vs Intel Core i5-760 Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the Intel Core i5-760 across every Cinebench workload, though the margins are consistently narrow. The largest advantage appears in Cinebench R15 multi-core, where the Intel part scores 466 against the Opteron's 454, a 2.6% lead. Single-core in the same test shows 65 versus 64, a 1.6% edge. These are not transformative differences, but they are uniform.

Moving to Cinebench R20, the Intel chip posts 1942 multi-core against 1894 for the AMD, a 2.5% gap. Single-core R20 results land at 273 versus 267, a 2.2% lead. The pattern repeats in Cinebench R23: 4624 versus 4510 multi-core (2.5% ahead) and 652 versus 636 single-core (2.5% ahead). Across all six head-to-head tests, the Intel Core i5-760 wins every round. The average benchmark score tells a similar story: 1337 for Intel versus 1304 for AMD, roughly a 2.5% overall advantage.

Context matters here. The Intel Core i5-760 sits at the 35th percentile of all CPUs in the database, and the Opteron 6328 also sits at the 35th percentile. These two processors are effectively peers in overall standing, even though the Intel part wins every direct comparison. The nearest rivals for the Intel chip include the Intel Core i5-4590T (average score 1340, 0.2% ahead of the i5-760) and the Intel Core i5-4670 (1347, 0.8% ahead). For the Opteron, the nearest rival is the Intel Core i5-6400 at 1307, which is 0.2% ahead of the AMD part. The Opteron also trails the AMD Athlon Gold 7220U by 0.6% and the Intel Core i7-3770T by 0.7% in average score.

What this means in practice: the Intel chip's wins are real but small. A 2.5% multi-core advantage in Cinebench R23 is within run-to-run variance for many workloads, but the consistency across all six tests suggests a genuine, if modest, performance edge. The Opteron's higher core count (8 versus 4) and higher clock speeds (3.20 GHz base, 3.80 GHz boost versus 2.80 GHz and 3.33 GHz) do not translate into a win in any recorded benchmark. The Intel architecture extracts more useful work per clock, and that shows in every test.

The Verdict

The data points to the Intel Core i5-760 as the faster processor in every recorded benchmark. It wins all six head-to-head tests, with margins ranging from 1.6% to 2.6%. If the decision rests purely on Cinebench performance, the Intel part is the correct pick. The Opteron 6328 does not win a single test in this comparison.

However, the benchmark database does not rank these chips far apart. Both sit at the 35th percentile of all CPUs, and the average scores differ by only 33 points out of roughly 1300. A buyer choosing between them should weigh other factors beyond raw Cinebench numbers, such as platform memory bandwidth and ECC support, which favor the AMD part. But for raw rendering performance, the Intel Core i5-760 is the winner.

The Opteron's 8-core design and higher boost clock of 3.80 GHz might suggest an advantage in heavily threaded workloads, yet the recorded data shows otherwise. The Intel chip leads by 2.5% in R23 multi-core despite having half the threads. This is a case where architecture efficiency overcomes a core count disadvantage.

Where Each One Wins

The Intel Core i5-760 wins all six recorded benchmark tests, so in the Cinebench suite it has no weaknesses relative to the Opteron. The largest margin is in R15 multi-core (2.6%), and the smallest is in R15 single-core (1.6%). If the workload is any of the tested Cinebench versions, the Intel part is the better choice.

The AMD Opteron 6328 does not win any recorded benchmark, but it has platform advantages that the benchmark scores do not capture. It supports ECC memory, which the Intel chip does not. It uses a quad-channel memory bus with a rated bandwidth of 59.7 GB/s, whereas the Intel chip uses dual-channel memory with no bandwidth figure recorded. For a server or workstation environment where data integrity and memory throughput matter more than Cinebench scores, the Opteron's platform features could be the deciding factor.

The Opteron also has a higher base clock (3.20 GHz versus 2.80 GHz) and a higher boost clock (3.80 GHz versus 3.33 GHz), which may help in lightly threaded workloads that do not scale with core count. Yet the recorded single-core benchmarks show the Intel chip ahead in every case, so clock speed alone does not deliver a win for AMD.

In short: pick Intel for Cinebench performance, pick AMD for ECC memory and quad-channel bandwidth, and accept that the AMD part will not win a Cinebench comparison in the database.
