AMD Opteron 6274 vs AMD Ryzen Embedded R2314 Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear, if narrow, picture. Across all six Cinebench tests, the AMD Ryzen Embedded R2314 comes out ahead of the AMD Opteron 6274. The wins are consistent, but the margins are slim. In Cinebench R15 multicore, the R2314 scores 493 against the Opteron's 483, a 2.1% lead. The single-core test in R15 is closer still, 69 versus 68, a 1.5% difference. This pattern repeats in R20, where the R2314 posts 2055 multicore and 289 single-core, against 2014 and 284 for the Opteron, translating to 2% and 1.8% advantages respectively. The newest test in the database, Cinebench R23, shows the R2314 at 4893 multicore and 690 single-core, while the Opteron manages 4796 and 677, with the R2314 leading by 2% and 1.9%. The overall win tally is 6 to 0 in favor of the Ryzen part.

It is importantly the average benchmark score for the R2314 is 1415, while the Opteron 6274 sits at 1387. This places both processors at the 37th percentile among all CPUs in the database. The R2314's nearest rivals include the AMD Ryzen 7 2700U and Intel Core i5-4460, both with an identical average score of 1415 and a 0% delta. The Opteron's closest competitor is the Intel Core i3-9100TE, which scores 1386, a 0.1% gap. These context points show that while the R2314 wins this head-to-head, it is not a dominant performer in the broader landscape; it sits in the same performance tier as several older desktop parts.

Architecture Differences

The two chips come from different eras of AMD design. The Ryzen Embedded R2314 is built on the Zen+ architecture, with the codename Picasso. It is a 2000 series part fabricated on a 12 nm process at GlobalFoundries. The die contains 4,940 million transistors on a 210 mm² slice of silicon. It has 4 cores and 4 threads, with a base clock of 2.10 GHz and a boost clock of 3.50 GHz. Its cache layout includes 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The memory controller supports DDR4 in a dual-channel configuration, delivering 42.7 GB/s of bandwidth, and ECC memory is supported. It also includes an integrated Radeon Vega 6 GPU and offers PCIe Gen 3 with 16 CPU lanes.

The Opteron 6274 is a much older design. It belongs to the Opteron 6000 series and uses the Bulldozer architecture under the codename Interlagos. It was manufactured on a 32 nm process, also at GlobalFoundries, with 2,400 million transistors spread across two dies, each measuring 315 mm². This chip provides 16 cores and 16 threads, running at a base clock of 2.20 GHz and a boost clock of 3.10 GHz. Its cache is organized differently: 768 KB of shared L1, 2 MB of L2 per module, and 8 MB of L3 per die. Memory support is DDR3 over a quad-channel bus, which provides 51.2 GB/s of bandwidth. It also supports ECC memory but lacks integrated graphics entirely. The PCIe interface is Gen 2.

The process node advantage is clear: 12 nm versus 32 nm. This explains why the R2314 can achieve comparable performance with a 15 W TDP, while the Opteron requires a 115 W TDP. The transistor count is also telling, with the R2314 packing more than double the transistors of the Opteron, despite a smaller die area. The R2314's boost clock is 400 MHz higher than the Opteron's, which contributes to its edge in single-threaded tests.

Specification Differences

The specifications show two very different designs. The Ryzen Embedded R2314 has 4 cores and 4 threads, a base clock of 2.10 GHz, and a boost clock of 3.50 GHz. The Opteron 6274 offers 16 cores and 16 threads, a base clock of 2.20 GHz, and a boost clock of 3.10 GHz. The R2314 is built on the Zen+ architecture with the Picasso codename, while the Opteron uses Bulldozer with the Interlagos codename. The process nodes differ: 12 nm for the R2314 versus 32 nm for the Opteron. Transistor counts are 4,940 million for the R2314 and 2,400 million for the Opteron. The die size is 210 mm² for the R2314, while the Opteron uses two dies of 315 mm² each.

Cache configurations diverge significantly. The R2314 has 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The Opteron has 768 KB of shared L1, 2 MB of L2 per module, and 8 MB of L3 per die. Memory support is DDR4 for the R2314 and DDR3 for the Opteron. The memory bus is dual-channel for the R2314 and quad-channel for the Opteron, with bandwidth figures of 42.7 GB/s and 51.2 GB/s respectively. Both support ECC memory. The R2314 has PCIe Gen 3 with 16 CPU lanes, while the Opteron has PCIe Gen 2. The R2314 includes an integrated Radeon Vega 6 GPU, while the Opteron has none.

The TDP figures are a major differentiator: 15 W for the R2314 versus 115 W for the Opteron. The sockets are also different, with the R2314 using AMD Socket FP5 and the Opteron using AMD Socket G34. The market segments differ, with the R2314 aimed at Desktop and the Opteron at Server/Workstation. Production status shows the R2314 as Active, while the Opteron is End-of-life. The release dates are far apart, with the Opteron launching in 2011 and the R2314 in 2022. The Opteron has a launch MSRP of $639, while the R2314 has no listed launch MSRP. The Opteron's part number is OS6274WKTGGGU, and the R2314's is YE2314C4T4MFH. Neither chip has an unlocked multiplier.

The Verdict

The data supports a straightforward choice for most scenarios. The AMD Ryzen Embedded R2314 wins every benchmark in this comparison, despite having only 4 cores against the Opteron's 16. It does so while consuming 15 W of power, a fraction of the Opteron's 115 W TDP. The R2314 is also a modern, active product with DDR4 support and an integrated GPU, making it a far more versatile part for current systems.

The Opteron 6274, by contrast, is an end-of-life server processor from a previous architecture generation. Its only advantages lie in theoretical memory bandwidth, due to its quad-channel DDR3 setup, and its higher core count. However, those cores do not translate into better Cinebench scores, as the architectural efficiency of Zen+ proves superior. The Opteron's 51.2 GB/s memory bandwidth exceeds the R2314's 42.7 GB/s, but this does not yield a performance win in any recorded test.

For a user building a low-power, compact system, the R2314 is the clear choice. It delivers better performance, newer features, and vastly lower power draw. For a legacy server workload that relies on many physical cores, the Opteron might still have a niche, but the benchmark data shows no scenario where it outperforms the R2314. The Ryzen part is the better processor by every measurable metric in this comparison. The Opteron's only claim to relevance is its historical position, but the recorded data indicates it is outclassed by a modern embedded chip with a quarter of the core count.
