AMD Opteron 3365 vs Intel Core i5-4440 Comparison

Where Each One Wins

The benchmark split between these two processors is completely one-sided. The Intel Core i5-4440 wins all five recorded Cinebench comparisons. The AMD Opteron 3365 does not record a single victory in any of the shared tests. The head-to-head data lists five tests, all won by the Intel part, with the Opteron taking zero wins.

This creates a clear use-case division. The Intel Core i5-4440 is the stronger choice for any workload that relies on the Cinebench rendering engine, which is a proxy for multi-threaded content creation and 3D rendering tasks. Its lead is consistent across every version of the test, from the older R15 through the more demanding R23.

The AMD Opteron 3365, despite having double the core count, cannot match the Intel part in these specific metrics. Its role in the database is as a server and workstation processor with a low power envelope, but the benchmark data does not support it as a performance leader in these tests. For buyers looking at the recorded data, the Intel Core i5-4440 is the one that wins in every measured category.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Opteron 3365 is built on the K10 architecture with the codename "Delhi," part of the Opteron 3000 series. It uses a 32 nm process node from GlobalFoundries. The die size is 315 mm² and it contains 1,200 million transistors.

The Intel Core i5-4440 uses the Haswell architecture, the same codename as its generation name. It is built on a more advanced 22 nm process node at Intel's own foundry. The die size is significantly smaller at 177 mm², yet it packs more transistors: 1,400 million. This indicates a denser, more efficient design.

Core configuration is a major divergence. The AMD part offers 8 cores and 8 threads, meaning no simultaneous multithreading. The Intel part offers 4 cores and 4 threads, also without hyper-threading. This doubles the physical core count on the AMD side, yet the benchmark results show the Intel part maintains a leading position in all recorded tests.

Cache layouts differ. The AMD Opteron 3365 has 384 KB of L1 cache, 4 MB of L2 cache, and 8 MB of shared L3 cache. The Intel Core i5-4440 has 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 6 MB of shared L3 cache. The AMD part has a larger total L3 allocation, but the Intel design still yields higher scores.

Both processors support DDR3 memory with dual-channel bus. The AMD part lists a memory bandwidth of 29.9 GB/s, while the Intel part does not have a recorded bandwidth figure in the database. Neither supports ECC memory. For PCI Express, the Intel part uses Gen 3, while the AMD part uses Gen 2.

Head-to-Head Benchmarks

The pattern is consistent across every recorded test, with the Intel Core i5-4440 beating the AMD Opteron 3365 by almost identical margins.

In Cinebench R15 single-core, the Intel part scores 57. The AMD part does not have a recorded single-core score for this test, so a direct comparison is not possible from the database. For the multicore version, Intel scores 410 against AMD's 349. That is a delta of -14.9% for the AMD part, meaning Intel leads by roughly 15%.

Cinebench R20 multicore shows the same relationship. Intel records 1712 points, AMD records 1457 points. The delta is again -14.9%. The single-core R20 test shows Intel at 241 and AMD at 205. That is also a -14.9% delta for the AMD part.

Cinebench R23 multicore follows the pattern: Intel scores 4077, AMD scores 3470, with a -14.9% delta. The single-core R23 test shows Intel at 575 and AMD at 489, a -15% delta for the AMD part. This is the widest recorded gap in percentage terms, but it is essentially the same as the others.

The key information here is the consistency. In every multicore and single-core test where both CPUs have a recorded score, the Intel Core i5-4440 wins by approximately 15%. The AMD's core-count advantage does not translate into a performance advantage. The data shows the Intel part is simply faster in this workload.

Specification Differences

The recorded specifications show several differences beyond the core count and cache.

The base clock differs: the AMD Opteron 3365 runs at 2.30 GHz, while the Intel Core i5-4440 runs at 3.10 GHz. The boost clock is identical at 3.30 GHz for both processors.

The power envelope is different. The AMD part has a 65 W TDP, while the Intel part has an 84 W TDP. The Intel chip draws more power but delivers the higher benchmark results.

The sockets are not interchangeable. The AMD uses AMD Socket AM3+, and the Intel uses Intel Socket 1150.

The integrated graphics are a major distinction. The AMD Opteron 3365 lists "On certain motherboards (Chipset feature)" for integrated graphics, meaning it relies on the motherboard chipset rather than an on-die GPU. The Intel Core i5-4440 includes Intel HD 4600 integrated graphics directly.

The market segments also differ. The AMD is aimed at Server/Workstation, while the Intel is a Desktop part. The AMD is listed as end-of-life, while the Intel has a release date of 2013-08-31 and no production status listed.

The process node is a notable difference: 32 nm for AMD versus 22 nm for Intel. The transistor count is 1,200 million for AMD and 1,400 million for Intel. The die size is 315 mm² for AMD and 177 mm² for Intel. The Intel part packs more transistors into a smaller physical area.

The part numbers are listed as OS3365OLW8KHK for AMD and SR14F for Intel. Neither part has a multiplier unlocked.

FAQ

Q: Which processor wins in the benchmark records?

A: The Intel Core i5-4440 wins all five recorded head-to-head tests. The AMD Opteron 3365 has no wins in the shared test suite.

Q: The AMD has 8 cores and the Intel has 4 cores. Why does the Intel win?

A: The data shows that having more cores does not guarantee better Cinebench performance. The Intel part wins despite half the core count, suggesting per-core efficiency is higher on the Intel design.

Q: What is the exact performance gap in percentage?

A: The Intel leads by -14.9% in Cinebench R15 multicore, R20 multicore, R20 single-core, and R23 multicore. The single-core R23 test shows a -15% delta.

Q: Do the processors support the same memory type?

A: Yes, both support DDR3 and use dual-channel memory. However, the AMD Opteron lists a memory bandwidth of 29.9 GB/s, while the Intel has no recorded bandwidth figure.

Q: Which processor has a lower power consumption?

A: The AMD Opteron 3365 has a 65 W TDP, while the Intel Core i5-4440 has an 84 W TDP. The AMD consumes less power in the specifications.

Q: Do both processors have integrated graphics?

A: The Intel Core i5-4440 has Intel HD 4600 integrated graphics. The AMD does not have on-die graphics; it relies on a chipset feature on certain motherboards.

The Verdict

The benchmark data is unambiguous. The Intel Core i5-4440 outperforms the AMD Opteron 3365 in every recorded Cinebench test, typically by about 15%. The AMD's larger core count, 8 versus 4, does not help it in these workloads. The Intel part also has a higher base clock at 3.10 GHz versus 2.30 GHz, and a more modern 22 nm process node.

Buyers should choose the Intel Core i5-4440 for any application that depends on Cinebench-Render performance, which includes 3D rendering and general multi-threaded production work. The Intel part is the faster chip in the database.

The AMD Opteron 3365 still has a role. It is a server and workstation processor, and it draws significantly less power: 65 W versus 84 W. For a system that must run within a tight power budget or in a server chassis with limited cooling, the AMD part offers a lower thermal footprint. The data also shows that it has a larger L3 cache, 8 MB versus 6 MB, which could be relevant in some cache-sensitive workloads.

However, for pure processing speed as measured by Cinebench, the Intel Core i5-4440 is the better choice. The final score in the database is 1179 for the Intel and 1194 for the AMD, but that overall average is skewed by different test sets. The head-to-head record is 5 wins for the Intel, 0 for the AMD. That is the only metric that matters for a direct comparison.
