AMD Opteron 6344 vs Intel Core i5-7440HQ Comparison

Head-to-Head Benchmarks

The benchmark data presents a surprisingly consistent picture: the AMD Opteron 6344 wins every single head-to-head comparison, across all six Cinebench tests. The Intel Core i5-7440HQ does not record a single victory. The margins are remarkably uniform, hovering around 10.8% to 11% in favor of the AMD part regardless of workload type.

In Cinebench R15 multicore, the Opteron scores 519 against the i5's 463, a 10.8% advantage. The single-core R15 test shows the same pattern: 73 for AMD versus 65 for Intel, an 11% gap. This is the largest delta in the entire comparison. Moving to Cinebench R20, the Opteron again leads by 10.8% in both multicore (2166 versus 1933) and single-core (305 versus 272). The R23 results continue the trend: 5158 versus 4603 in multicore (10.8%) and 728 versus 649 in single-core (10.9%).

What is striking here is that the Opteron, a server part from 2012 with a 32nm Piledriver architecture, consistently outperforms a 2017 Kaby Lake mobile processor by roughly the same margin across every test. This uniformity suggests the performance gap is structural rather than workload-dependent. The i5-7440HQ's higher boost clock of 3.80 GHz compared to the Opteron's 3.20 GHz does not translate into a single-core advantage in these measurements. Instead, the Opteron's single-core scores are 11% higher despite the clock deficit, implying architectural efficiency differences that favor the older AMD design in Cinebench's rendering workloads.

The average benchmark scores reflect similar overall positioning. The i5-7440HQ averages 1527, placing it in the 38th percentile of all CPUs. Its nearest rivals include the Intel Core i5-4670S at 1526 (0% delta) and the Intel Pentium Gold G7400E at 1524 (0.2% ahead). The Opteron 6344 averages 1492, also in the 38th percentile, with the Intel Core i5-4590S at 1493 (0% delta) as its closest competitor. Both processors sit in the same percentile band, yet in direct head-to-head Cinebench comparisons, the Opteron consistently wins by roughly 11%. This suggests that Cinebench specifically favors the Opteron's 12-core configuration, while other workload types might close the gap.

Where Each One Wins

The use-case split is straightforward given the data. The AMD Opteron 6344 wins in every measured category, so the question becomes which workloads benefit most from its specific strengths. The 12-core configuration with 12 threads gives it a clear structural advantage in multi-threaded rendering tasks, which is exactly what Cinebench measures. The Opteron's 10.8% multicore lead in R23 (5158 versus 4603) reflects this core-count superiority.

Interestingly, the Opteron also wins the single-core tests despite having a lower boost clock (3.20 GHz versus 3.80 GHz). This means even in lightly threaded scenarios, the i5-7440HQ cannot overcome the per-core performance difference measured in these benchmarks. The 11% single-core gap in R15 suggests the Opteron's Piledriver cores deliver more effective performance per clock in this specific workload.

For users running Cinebench-style rendering workloads, the Opteron 6344 is the clear choice based on the recorded data. The i5-7440HQ, being a mobile processor in the Intel BGA 1440 form factor, targets a different physical environment entirely. Its 45W TDP versus the Opteron's 115W TDP indicates the Intel part is designed for power-constrained laptops, while the Opteron targets server and workstation sockets. The benchmark data shows no scenario where the i5-7440HQ outperforms the Opteron, so the selection depends on platform requirements rather than measured performance.

Specification Differences

The two processors differ substantially across nearly every specification category. The Intel Core i5-7440HQ has 4 cores and 4 threads, while the AMD Opteron 6344 has 12 cores and 12 threads. Base clocks are 2.80 GHz for Intel and 2.60 GHz for AMD, with boost clocks of 3.80 GHz and 3.20 GHz respectively. The TDP difference is significant: 45W for the i5 versus 115W for the Opteron.

The socket types are incompatible: Intel BGA 1440 for the i5, AMD Socket G34 for the Opteron. The i5 supports DDR3 and DDR4 memory over a dual-channel bus, while the Opteron supports only DDR3 but over a quad-channel bus with a recorded memory bandwidth of 59.7 GB/s. The Intel part does not support ECC memory, while the Opteron does. PCIe capabilities differ as well: the i5 offers Gen 3 with 16 lanes (CPU only), while the Opteron offers Gen 2.

The i5-7440HQ includes integrated graphics (Intel HD Graphics 630), while the Opteron has none. Market segments differ: the i5 is a mobile processor, the Opteron is a server/workstation part. Both are end-of-life products. The release dates are roughly four years apart: January 2017 for the Intel, November 2012 for the AMD. Launch MSRP values are $250 for the i5 and $415 for the Opteron. Neither processor has an unlocked multiplier. The part numbers are SR32R for Intel and OS6344WKTCGHK for AMD.

Architecture Differences

The architectural divide is substantial. The Intel Core i5-7440HQ uses the Kaby Lake architecture on a 14nm process node, fabricated by Intel. Its codename is Kaby Lake-H, and it belongs to the Core i5 (Kaby Lake-H) generation. The die size is 126 mm². The cache layout consists of 64 KB L1 per core, 256 KB L2 per core, and 6 MB shared L3.

The AMD Opteron 6344 uses the Piledriver architecture on a 32nm process node, fabricated by GlobalFoundries. Its codename is Abu Dhabi, part of the Opteron (Abu Dhabi) generation within the Opteron 6000 series. The transistor count is 2,400 million, and the die size is listed as 2x 315 mm², indicating a dual-die design. The cache configuration differs fundamentally: 576 KB L1 total, 2 MB L2 per module, and 8 MB L3 per die.

These architectural differences explain several observed behaviors. The 14nm Intel process is much newer than AMD's 32nm process, which typically implies better power efficiency. The 45W TDP of the i5 versus 115W for the Opteron supports this interpretation. However, the Opteron's 12-core design with 2,400 million transistors provides far more parallel execution resources, which directly contributes to its Cinebench multicore victories. The dual-die layout with 8 MB L3 per die suggests a NUMA-style memory topology, which the quad-channel DDR3 interface with 59.7 GB/s bandwidth is designed to feed.

The absence of integrated graphics on the Opteron is notable since the i5 includes Intel HD Graphics 630, reflecting the different target platforms. The Opteron's ECC memory support and server-oriented features align with server and workstation duties, while the i5's BGA socket is designed for mobile integration. Neither processor supports the same memory types, with the i5 supporting DDR3 and DDR4 while the Opteron only supports DDR3.

The Verdict

The data points to a clear conclusion: the AMD Opteron 6344 wins every measured benchmark comparison with margins of 10.8% to 11% over the Intel Core i5-7440HQ. Users seeking maximum Cinebench performance would choose the Opteron based on the recorded scores. The 12-core, 12-thread configuration delivers 5158 in R23 multicore versus 4603 for Intel, and the single-core results follow the same pattern. The i5-7440HQ does not win a single test.

However, the specifications reveal why these results are not surprising. The Opteron has triple the core count, a quad-channel memory bus with 59.7 GB/s bandwidth, ECC support, and a server-class socket, all pointing to a fundamentally different performance tier. The i5-7440HQ is a mobile processor in the 38th percentile, tied with the Opteron in overall percentile rank. Both parts are end-of-life, making new adoption unlikely.

The i5-7440HQ fits laptops and mobile systems where its 45W TDP and integrated graphics are appropriate. The Opteron requires a server or workstation platform with its 115W TDP and Socket G34 socket. Users constrained by these physical platform requirements should pick accordingly. For pure rendering throughput measured by Cinebench, the Opteron is the stronger option.

The consistent 10.8% to 11% delta across all tests, regardless of Cinebench version or core count, suggests the Opteron's architectural efficiency in the specific workload is simply superior in the recorded measurements. The i5-7440HQ base clock of 3.80 GHz cannot compensate at any point. Neither processor offers value considerations beyond its launch MSRP, and no benchmark advantage exists for Intel in this comparison.
