Q: Does either processor have integrated graphics?

A: The Intel Core i5-4460 includes Intel HD 4600 integrated graphics. The AMD Opteron 6378 has no integrated graphics, requiring a discrete GPU.

Q: Which chip wins in all recorded head-to-head benchmarks?

A: The AMD Opteron 6378 wins all 6 head-to-head benchmark comparisons, with deltas ranging from 19.4% to 20.3% across Cinebench R15, R20, and R23 tests.

Architecture Differences

The AMD Opteron 6378 is built on the Piledriver architecture, codenamed Abu Dhabi, part of the Opteron 6000 series. It uses a 32 nm process from GlobalFoundries and packs 2,400 million transistors across a dual-die design with a die size of 2x 315 mm². The cache layout is module-based: 768 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. This is a server and workstation part that supports quad-channel DDR3 memory with ECC, giving it a memory bandwidth of 59.7 GB/s. The Opteron uses PCIe Gen 2 and fits into AMD Socket G34. It was released in November 2012 and is now end-of-life.

The Intel Core i5-4460 uses the Haswell architecture, also codenamed Haswell, built on a 22 nm process by Intel. It contains 1,400 million transistors on a single 177 mm² die. The cache structure is per-core: 64 KB of L1 per core, 256 KB of L2 per core, and a shared 6 MB L3. This desktop chip supports dual-channel DDR3 with a memory bandwidth of 25.6 GB/s, and it does not support ECC. It uses PCIe Gen 3 with 16 lanes from the CPU and includes Intel HD 4600 integrated graphics. It fits into Intel Socket 1150 and was released in May 2014, also end-of-life.

The architectures differ fundamentally in design philosophy. The Opteron prioritizes many cores and high memory throughput for server workloads, while the Core i5 prioritizes higher clocks and per-core efficiency for desktop tasks. The Opteron has no integrated graphics and supports ECC, two features that align with server use. The Core i5 has integrated graphics and no ECC, aligning with consumer desktops. The process nodes differ (32 nm vs 22 nm), and the transistor counts reflect the Opteron's larger, dual-die design.

Where Each One Wins

The AMD Opteron 6378 wins in every recorded benchmark category, particularly in multi-core workloads. Its 16 cores and 16 threads give it a commanding lead in threaded rendering tasks. In Cinebench R23 multi-core, the Opteron scores 5005 versus the Core i5's 4188, a 19.5% advantage. This pattern repeats across R15, R20, and R23 multi-core tests, where the Opteron consistently leads by roughly 19.5% to 19.7%. For workloads that scale well across cores, such as video rendering, scientific computing, or server-side processing, the Opteron is the clear choice.

The Core i5-4460 has no benchmark wins in the recorded data. However, its lower TDP of 84 watts versus the Opteron's 115 watts makes it more power-efficient for light desktop tasks. The Core i5 also has integrated graphics, which means a system can run without a discrete GPU. Its higher base clock of 3.20 GHz versus 2.40 GHz may help in single-threaded tasks, but the recorded benchmarks show the Opteron still wins single-core tests by about 20%. The Core i5 uses a newer process node and has a smaller die, but these factors do not translate into benchmark victories in the data.

For a desktop user who needs a complete system with minimal components, the Core i5's integrated graphics and lower power draw are practical advantages. For a server or workstation user who needs maximum throughput in threaded applications, the Opteron's core count and memory bandwidth dominate. The data shows no scenario where the Core i5 wins a performance test.

Head-to-Head Benchmarks

The head-to-head data covers six Cinebench tests, and the AMD Opteron 6378 wins all of them. The largest margin is in Cinebench R15 single-core, where the Opteron scores 71 against the Core i5's 59, a 20.3% delta. This is notable because the Core i5 has a higher base clock and boost clock, yet it still loses single-core performance. The smallest margin is in Cinebench R20 single-core, where the Opteron leads by 19.4%, scoring 296 versus 248.

In multi-core tests, the Opteron's lead is consistent. Cinebench R15 multi-core shows 504 versus 421, a 19.7% delta. Cinebench R20 multi-core shows 2102 versus 1758, a 19.6% delta. Cinebench R23 multi-core shows 5005 versus 4188, a 19.5% delta. The consistency across all tests, roughly 19.4% to 20.3%, indicates that the Opteron's advantage is not workload-specific but rather a general performance lead.

The Core i5 has additional Geekbench scores in the database: 3035 multi-core and 1018 single-core. The Opteron does not have corresponding Geekbench scores in the recorded data, so those cannot be directly compared. The recorded head-to-head only includes Cinebench tests, and the Opteron wins all of them. The average benchmark score for the Opteron is 1447, while the Core i5 averages 1415, a difference of about 2.3%.

The Opteron's nearest rivals include the Intel Core i5-7300HQ with an average score of 1448 (delta -0.1%), the Intel Xeon E3-1505L v5 at 1446 (delta 0.1%), the AMD Ryzen 3 2200GE at 1444 (delta 0.2%), and the AMD Ryzen 5 2400G at 1439 (delta 0.6%). The Core i5-4460's nearest rivals include the AMD Ryzen Embedded R2314 and the AMD Ryzen 7 2700U, both at 1415 (delta 0%), the Intel Core i7-3840QM at 1416 (delta -0.1%), and the Intel Core i7-2700K at 1419 (delta -0.3%). These rival comparisons show that both processors sit in a similar overall performance tier, despite the Opteron winning every direct head-to-head test.

The Verdict

The data is unambiguous: the AMD Opteron 6378 wins every recorded benchmark against the Intel Core i5-4460. If your workload involves multi-threaded rendering, server processing, or any task that can use 16 cores, the Opteron is the better performer. Its quad-channel memory with ECC support and 59.7 GB/s bandwidth make it suitable for memory-intensive server applications. The Opteron's percentile rank of 38 versus the Core i5's 37 shows they are close in overall standings, but the direct head-to-head results favor the AMD part by roughly 20% across the board.

The Intel Core i5-4460 is the better choice only if you value lower power consumption (84 W versus 115 W), integrated graphics, or a smaller physical footprint. Its dual-channel memory and lack of ECC make it less suited for server reliability scenarios. For a desktop build where a discrete GPU is already present, the Core i5 offers no performance advantage in the recorded tests.

The launch MSRP difference is notable, but the performance data does not suggest the Core i5 is a bargain. The Opteron's higher price corresponds to a clear performance lead. If you need a server or workstation CPU with maximum throughput, choose the AMD Opteron 6378. If you need a simple desktop chip with integrated graphics and lower power draw, the Intel Core i5-4460 is acceptable, but understand that it loses every benchmark comparison in the database. The verdict from the measurements is straightforward: the Opteron is the faster processor, and the Core i5 is the more modest, power-conscious option.
