AMD Opteron 4280 vs AMD Ryzen 3 1200 Comparison

The Verdict

The recorded benchmark data splits this comparison into two distinct workloads. The AMD Ryzen 3 1200 wins three of the four head-to-head tests, including both single-core tests and the Cinebench R15 multi-core test. The AMD Opteron 4280 wins only one test, but it is the most demanding multi-threaded workload in the database: Cinebench R23 multi-core. For users prioritizing modern single-thread performance and efficient dual-channel operation, the Ryzen 3 1200 is the clear choice. For those running heavily threaded, sustained workloads on a server platform, the Opteron 4280's eight cores deliver a measurable advantage in the newest Cinebench multi-core benchmark.

Architecture Differences

The two processors come from different AMD eras. The Ryzen 3 1200 uses the Zen architecture on a 14 nm process node, built by GlobalFoundries with 4,800 million transistors on a 213 mm² die. It has 4 cores and 4 threads, with a 65 watt TDP. Its cache layout is per-core: 96 KB of L1 per core, 512 KB of L2 per core, and 8 MB of shared L3. It uses DDR4 memory on a dual-channel bus with 42.7 GB/s bandwidth, and it supports ECC memory. PCIe is Gen 3 with 16 CPU lanes. The multiplier is unlocked, and the part number is YD1200BBM4KAEYD1200BBAEBOX.

The Opteron 4280 belongs to the Opteron 4000 series, codenamed Valencia, using the Bulldozer architecture on a 32 nm process node. It has 8 cores and 8 threads, with a 95 watt TDP. Its cache is expressed differently: 384 KB of L1 total, 8 MB of L2 total, and 8 MB of shared L3. It uses DDR3 memory on a dual-channel bus with 25.6 GB/s bandwidth, also supporting ECC. PCIe is Gen 2. The multiplier is locked, and the part number is OS4280WLU8KGU. The production status for the Ryzen is active, while the Opteron is end-of-life.

The process node difference (14 nm versus 32 nm) and transistor count (4,800 million versus 1,200 million) explain much of the efficiency gap. The Ryzen delivers higher single-core scores while consuming less power on paper. The Opteron counters with double the physical cores, though each core is architecturally older and slower on a per-thread basis.

Head-to-Head Benchmarks

The database records four direct comparisons. In Cinebench R15 multi-core, the Ryzen 3 1200 scores 480 against the Opteron's 385, a 24.7% advantage. That is a substantial margin for a 4-core part against an 8-core server chip. In Cinebench R15 single-core, the Ryzen scores 135 versus 54, a 150% advantage. That is the largest delta in the dataset and reflects the per-thread performance gap between Zen and Bulldozer.

In Cinebench R23 multi-core, the results reverse. The Opteron 4280 scores 3828 against the Ryzen's 3013, a 21.3% advantage for the Opteron. This is the only test the Opteron wins, and it shows that the newer Cinebench version scales better with additional cores. The Ryzen's 4 threads cannot match the Opteron's 8 threads in this workload. In Cinebench R23 single-core, the Ryzen returns to dominance with 834 versus 540, a 54.4% lead.

The pattern is consistent: the Ryzen wins every single-threaded test and the older multi-core test, while the Opteron wins only the newest multi-core test. The average benchmark score tells a similar story. The Ryzen's average is 1116, and the Opteron's is 1107, a difference of less than 1%. Both sit at the 31st percentile of all CPUs in the database.

Specification Differences

The two processors differ in nearly every hardware field. The Ryzen has 4 cores and 4 threads; the Opteron has 8 cores and 8 threads. Base clocks are 3.10 GHz for the Ryzen and 2.80 GHz for the Opteron. Boost clocks are 3.40 GHz versus 3.50 GHz, slightly favoring the Opteron at peak. TDP is 65 watts versus 95 watts, favoring the Ryzen. Sockets differ: AM4 for the Ryzen, C32 for the Opteron. Architecture is Zen versus Bulldozer. Process node is 14 nm versus 32 nm. Transistor count is 4,800 million versus 1,200 million. Die size is 213 mm² versus 315 mm².

Cache is arranged differently. The Ryzen uses per-core L1 and L2, while the Opteron reports total L1 and L2. L3 is 8 MB shared on both, but the Ryzen's L3 is shared across 4 cores while the Opteron's is shared across 8. Memory support is DDR4 versus DDR3. Memory bandwidth is 42.7 GB/s versus 25.6 GB/s. PCIe generation is Gen 3 versus Gen 2. The Ryzen has an unlocked multiplier; the Opteron's is locked. Release dates are July 2017 for the Ryzen and November 2011 for the Opteron. The Ryzen's launch MSRP is $109. The Opteron's is $255.

Where Each One Wins

The Ryzen 3 1200 wins in every scenario that depends on per-thread speed. Its Cinebench R15 single-core score of 135 is 150% higher than the Opteron's 54. Its Cinebench R23 single-core score of 834 is 54.4% higher. It also wins the Cinebench R15 multi-core test with 480 versus 385, a 24.7% lead, meaning that even in an older multi-threaded benchmark, its four faster cores outperform the Opteron's eight slower ones. The Ryzen also has a lower TDP, higher memory bandwidth, newer PCIe generation, and an unlocked multiplier. It is the better choice for desktop workloads, single-threaded applications, and any environment where power efficiency and modern platform features matter.

The Opteron 4280 wins only in the newest multi-threaded benchmark. Its Cinebench R23 multi-core score of 3828 beats the Ryzen's 3013 by 21.3%. This indicates that in a modern, heavily threaded workload that scales well with core count, the Opteron's eight physical cores provide a real advantage. Its higher boost clock of 3.50 GHz versus 3.40 GHz also helps in peak scenarios. The Opteron is the better choice for server or workstation environments running sustained multi-threaded workloads that can utilize all eight cores. Its end-of-life status and older DDR3 platform, however, mean that the Ryzen offers a more current foundation for new builds. The data shows a clear trade-off: the Ryzen wins on efficiency and single-thread performance, while the Opteron wins on raw multi-thread throughput in the latest Cinebench release.
