AMD Opteron 6276 vs Intel Core i5-7440HQ Comparison

The AMD Opteron 6276 and Intel Core i5-7440HQ are both end-of-life processors, but they target different segments: the Opteron is a 16-core server part from the Opteron 6000 series, while the i5 is a 4-core mobile part from the Core i5 line. In the database's head-to-head Cinebench results, the Opteron wins all six tests, with deltas from 16.9% to 17.3%. The Opteron's average benchmark score is 1560, the i5's is 1527. The Opteron's percentile rank is 39, the i5's is 38. The i5 also has Geekbench scores in the database, while the Opteron does not.

Head-to-Head Benchmarks

All six head-to-head tests are Cinebench workloads, spanning R15, R20, and R23, each with multi-core and single-core variants. The Opteron 6276 wins every one. In Cinebench R15 multi-core, the Opteron scores 543 against 463, a 17.3% advantage. In R15 single-core, the Opteron scores 76 against 65, a 16.9% lead. The R20 multi-core test shows 2265 versus 1933, a 17.2% delta. R20 single-core shows 319 versus 272, a 17.3% delta. R23 multi-core shows 5395 versus 4603, a 17.2% delta. R23 single-core shows 761 versus 649, a 17.3% delta.

The consistency of these deltas is striking. The Opteron's lead is nearly identical across multi-core and single-core tests, ranging only from 16.9% to 17.3%. This suggests the advantage is architectural rather than a matter of thread scaling. The i5 has higher clocks: a base of 2.80 GHz versus 2.30 GHz, and a boost of 3.80 GHz versus 3.20 GHz. Despite that, the Opteron produces higher Cinebench scores in every recorded test.

The broader database context reinforces the gap. The Opteron's average score of 1560 places it within 0.2% of the Intel Core i3-1115G4E (1559), the AMD Ryzen 3 1300X (1562), the AMD FX-8350 (1557), and the Intel Xeon E3-1268L v5 (1557). The i5's average of 1527 places it within 0.9% of the Intel Core i5-4670S (1526), the Intel Pentium Gold G7400E (1524), the Intel Xeon E5-1428L v2 (1537), and the Intel Core i7-8665U (1513). The Opteron's percentile of 39 is higher than the i5's 38. The head-to-head record is 6 wins for the Opteron and 0 for the i5.

Architecture Differences

Both processors are end-of-life, but they represent different design eras. The Opteron 6276 uses AMD's Bulldozer architecture, codenamed Interlagos, built on a 32 nm process at GlobalFoundries. The i5-7440HQ uses Intel's Kaby Lake architecture, codenamed Kaby Lake-H, built on a 14 nm process at Intel. The Opteron is from the Opteron 6000 series, while the i5 is from the Core i5 line with the Kaby Lake-H generation.

The core counts differ substantially: the Opteron has 16 cores and 16 threads, the i5 has 4 cores and 4 threads. The Opteron's die is 2x 315 mm² and contains 2,400 million transistors. The i5's die is 126 mm²; its transistor count is not recorded in the database.

Cache hierarchies are organized differently. The Opteron has 768 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. The i5 has 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. The Opteron's L3 is per die, while the i5's L3 is shared across all cores.

Memory support differs in both type and width. The Opteron uses DDR3 with a quad-channel bus and a recorded bandwidth of 51.2 GB/s. The i5 supports DDR3 and DDR4 with a dual-channel bus; its bandwidth is not recorded. ECC memory is supported on the Opteron but not on the i5.

PCIe connectivity: the Opteron uses Gen 2, while the i5 uses Gen 3 with 16 lanes (CPU only). The i5 includes Intel HD Graphics 630; the Opteron has no integrated graphics. The Opteron uses AMD Socket G34 and is a server/workstation part. The i5 uses Intel BGA 1440 and is a mobile part.

Power and clocks: the Opteron has a TDP of 115 W, a base clock of 2.30 GHz, and a boost clock of 3.20 GHz. The i5 has a TDP of 45 W, a base clock of 2.80 GHz, and a boost clock of 3.80 GHz. Both have locked multipliers. The Opteron was released on 2011-11-13, the i5 on 2017-01-02.

The Verdict

The recorded data is unambiguous in head-to-head terms: the Opteron 6276 wins all six Cinebench tests, with deltas between 16.9% and 17.3%. Its average benchmark score is 1560 versus 1527 for the i5, and its percentile is 39 versus 38. For any workload represented by Cinebench, the Opteron is the faster processor.

That said, the i5 has features that suit a different use case. It has higher clocks, a lower TDP of 45 W versus 115 W, integrated graphics, DDR4 support, PCIe Gen 3, and a newer release date. The Opteron offers ECC memory, quad-channel DDR3 with 51.2 GB/s bandwidth, and 16 cores. The i5 has Geekbench scores in the database (3043 multi-core, 1184 single-core), while the Opteron has no Geekbench results, so for that specific benchmark the i5 has recorded data and the Opteron does not.

Who should pick which? The Opteron is the choice for server or workstation workloads that benefit from 16 cores, ECC memory, and high memory bandwidth. The i5 is the choice for mobile systems where integrated graphics, lower power, and a newer process node are priorities. The data does not show the i5 winning any head-to-head test, but it does show the i5 with a higher clock speed and a much lower TDP.

The Opteron's nearest rivals in the database are the Intel Core i3-1115G4E (1559, delta 0.1%), AMD Ryzen 3 1300X (1562, delta -0.1%), AMD FX-8350 (1557, delta 0.2%), and Intel Xeon E3-1268L v5 (1557, delta 0.2%). The i5's nearest rivals are the Intel Core i5-4670S (1526, delta 0%), Intel Pentium Gold G7400E (1524, delta 0.2%), Intel Xeon E5-1428L v2 (1537, delta -0.7%), and Intel Core i7-8665U (1513, delta 0.9%). These rival comparisons show both processors sitting in the middle of their respective peer groups.
