AMD Opteron 6272 vs Intel Celeron G6900E Comparison

The AMD Opteron 6272 and the Intel Celeron G6900E land in the same neighborhood of the database, but the head-to-head data is strikingly one-sided: the Opteron wins all six recorded Cinebench contests, by a margin that barely wavers. What makes this matchup interesting is not the spread of outcomes, it is the consistency of them, and the odd fact that both chips sit at the same percentile versus all CPUs in the database, 35th, despite the Opteron's clean sweep. The Opteron's sixteen Bulldozer cores give it the throughput advantage; the Celeron's case rests entirely on platform modernity, efficiency, and connectivity rather than raw rendering performance.

Head-to-Head Benchmarks

Every single recorded benchmark goes to the Opteron 6272, and every single one lands within a fraction of a point of an 18.4 percent victory. That uniformity is rare in the database and worth dwelling on, because it tells you the gap between these two parts is structural rather than workload-dependent.

In Cinebench R15 multi-core, the Opteron scores 448 against the Celeron's 366, a delta of 18.3 percent. In Cinebench R20 multi-core it is 1870 versus 1525, an 18.4 percent gap. Cinebench R23 multi-core reads 4454 versus 3632, another 18.5 percent win. The single-core results repeat the pattern almost exactly: 63 to 51 in R15 (19 percent), 263 to 215 in R20 (18.3 percent), and 628 to 512 in R23 (18.5 percent).

Two conclusions follow. First, the Opteron's per-thread throughput is genuinely ahead, not merely its aggregate throughput. A 2-core, 2-thread Celeron at 3.00 GHz without a boost clock is beaten in single-core rendering by an eight-generation-older server part whose boost tops out at 3.00 GHz. Second, the near-identical multi-core and single-core deltas indicate the Opteron's sixteen cores scale as expected: its advantage does not collapse when the workload spreads across threads.

For context, the Celeron's average benchmark score of 1321 places it alongside its nearest rivals in the database: the Celeron G6900T (1321, 0 percent delta), the Core i5-4570R (1318, 0.2 percent), the Core i7-3770T (1314, 0.6 percent), and the Core i5-2500K (1329, -0.6 percent). The Opteron's average of 1288 puts it next to the Core i7-3630QM (1289), the Core i5-4670R (1286), the Core i5-3570 (1286), and the Core i5-3570K (1293). In other words, the averages are within roughly 2.5 percent of each other, which is exactly why the database flags them as comparable overall, even though the head-to-head Cinebench sample is lopsided. The Celeron's Geekbench results, 1561 single-core and 2702 multi-core, have no Opteron counterpart recorded, so the comparison leans entirely on the Cinebench suite.

Where Each One Wins

On pure benchmark evidence, the Opteron 6272 wins everything the database measured. It wins multi-core rendering by roughly 18.4 percent across three Cinebench generations, and it wins single-core rendering by the same margin. For any workload that resembles these tests, sustained render throughput, batch processing that scales with threads, the Opteron is the faster recorded part.

The Celeron's wins come from the specification sheet rather than the score tables, and they are real even if they are not benchmark wins. It supports both DDR4 and DDR5 memory over a dual-channel bus, against the Opteron's DDR3. It offers PCIe Gen 5 connectivity against the Opteron's Gen 2, a generational leap in peripheral bandwidth. It carries integrated UHD Graphics 710 where the Opteron has none, so it can drive a display without a discrete graphics card. And its 46 W TDP is dramatically lower than the Opteron's 115 W, a qualitative and quantitative efficiency advantage backed by the smaller 10 nm node. The Celeron is also an active product, while the Opteron is end-of-life, which matters for platform longevity and availability of new stock.

Architecture Differences

These chips come from different worlds. The Celeron G6900E is an Alder Lake-S desktop part built on Intel's 10 nm process at Intel's own foundries, released in January 2022. It has 2 cores and 2 threads, a 3.00 GHz base clock, no boost clock, and a locked multiplier. Its cache layout is 80 KB of L1 per core, 1.25 MB of L2 per core, and 4 MB of shared L3.

The Opteron 6272 is an Interlagos server processor from the Opteron 6000 series, built on GlobalFoundries' 32 nm process and released in November 2011. Its Bulldozer architecture delivers 16 cores and 16 threads with a 2.10 GHz base and a 3.00 GHz boost, also with a locked multiplier. It packs 2,400 million transistors across a dual-die package of 2x 315 mm², with 768 KB of L1, 2 MB of L2 per module, and 8 MB of L3 per die. Its quad-channel DDR3 memory controller provides 51.2 GB/s of memory bandwidth, and it supports ECC memory, a server-grade reliability feature the Celeron lacks entirely. The sockets are incompatible by design: Intel Socket 1700 for the Celeron, AMD Socket G34 for the Opteron, so this comparison spans two separate platforms that cannot be swapped into each other's boards.

FAQ

Q: Which CPU is faster in the recorded benchmarks?

A: The Opteron 6272 wins all six head-to-head Cinebench tests, by margins of 18.3 to 19 percent in every case, covering both multi-core and single-core results.

Q: How can the Opteron win every benchmark if both CPUs sit at the same percentile?

A: Both parts sit at the 35th percentile versus all CPUs, and their average scores, 1321 for the Celeron and 1288 for the Opteron, are close. The Opteron's rivals by average score are mainstream Ivy Bridge and Haswell quad-core parts, while the Celeron's rivals are older efficiency-focused parts, so each lands in the same overall neighborhood through different paths.

Q: Does the Celeron at 3.00 GHz beat the Opteron in single-core work?

A: No. The Opteron boosts to 3.00 GHz and records single-core wins in every Cinebench generation: 63 versus 51 in R15, 263 versus 215 in R20, and 628 versus 512 in R23.

Q: Which chip uses less power?

A: The Celeron, at a 46 W TDP versus the Opteron's 115 W, a substantial efficiency edge reinforced by its 10 nm node against the Opteron's 32 nm process.

Q: Which platform has better memory and expansion support?

A: The Celeron. It supports DDR4 and DDR5 on a dual-channel bus with PCIe Gen 5. The Opteron counters with quad-channel DDR3 at 51.2 GB/s and ECC support, but its PCIe is limited to Gen 2.

Q: Are either of these CPUs still in production?

A: The Celeron G6900E is listed as active. The Opteron 6272 is end-of-life, with a launch MSRP of $523 and part number OS6272WKTGGGU.

The Verdict

The data delivers a split decision despite the clean benchmark sweep. If the goal is rendering throughput and the Cinebench results are the guide, the Opteron 6272 is the pick: it is roughly 18.4 percent faster in multi-core and single-core alike, and its sixteen threads are made for parallel workloads. Its ECC memory support and quad-channel bandwidth reinforce the server pedigree.

If the goal is a modern, efficient desktop, the Celeron G6900E is the rational choice despite losing every benchmark. It draws 46 W instead of 115 W, runs on a current 10 nm node, offers DDR4 and DDR5 support, PCIe Gen 5, and integrated UHD Graphics 710 in a package that needs no discrete GPU and no legacy server platform. Its average score of 1321 actually edges the Opteron's 1288, and its rival set shows it matching well-known desktop parts of the Ivy Bridge and Haswell era. For buyers weighing these two specifically, the benchmark tables favor the Opteron, but the specification tables favor the Celeron, and only the workload decides which table matters more.
