AMD Opteron 4332 HE vs Intel Core i7-2720QM Comparison

The Verdict

The benchmark data presents a surprisingly uniform picture for these two very different processors. The Intel Core i7-2720QM wins all five head-to-head Cinebench comparisons, yet the margins are remarkably narrow. In multi-core tests, the Intel part leads by between 2.6% and 2.7%; in single-core tests, the margin is 2.7% to 3.0%. This is not a dominant victory, it is a consistent but modest edge.

For a server/workstation part with six physical cores, the AMD Opteron 4332 HE staying within roughly 3% of a mobile quad-core with hyper-threading suggests the Piledriver architecture's multi-threaded efficiency is not translating into a decisive core-count advantage. The Opteron's average benchmark score of 1144 sits just 1.4% above the Intel chip's 1128 average, which places both firmly in the same performance tier. Both processors occupy the 32nd percentile among all CPUs in the database, meaning they are effectively peers in overall capability.

The choice between them depends entirely on platform context. The Opteron 4332 HE is a Socket C32 server part, designed for dual-socket or dense single-socket racks where ECC memory and server-grade reliability matter. The Core i7-2720QM is a mobile processor on BGA 1224, built into laptops with integrated graphics and lower power draw. If the system is a server, the Opteron is the only sensible pick. If the system is a laptop, the Intel chip is the only option. The data shows they trade blows within a narrow band, so platform dictates the decision more than raw compute.

Architecture Differences

The two chips represent fundamentally different design philosophies from the same 32 nm manufacturing era. The AMD Opteron 4332 HE uses the Piledriver architecture, codenamed Seoul, which is a refined version of Bulldozer. It packs six cores with six threads, meaning no simultaneous multi-threading. Each core has its own 48 KB of L1 cache (totaling 288 KB) and 1 MB of L2 cache per core (6 MB total). The shared L3 cache is 8 MB. The die size is 315 mm² with 1,200 million transistors.

The Intel Core i7-2720QM uses Sandy Bridge, a monolithic design with four cores and eight threads via hyper-threading. Its cache hierarchy is described per core: 64 KB L1 and 256 KB L2 per core, with 6 MB of shared L3. The die is notably smaller at 216 mm² with 1,160 million transistors, nearly matching the AMD chip's transistor count despite having fewer physical cores. Intel lists its foundry as Intel itself, while AMD's foundry field is not recorded.

Clock speeds tell an interesting story. The Opteron has a higher base clock at 3.00 GHz and boosts to 3.70 GHz. The Intel chip starts at 2.20 GHz and boosts to 3.30 GHz. Despite the Opteron's clock advantage of 0.80 GHz at base and 0.40 GHz at boost, the Intel part wins every benchmark. This indicates Sandy Bridge's per-core instruction efficiency more than compensates for the clock deficit. The Opteron's higher TDP of 65 watts versus 45 watts for the Intel chip also suggests more power is being spent to achieve similar or slightly lower performance.

The Opteron supports DDR3 memory but does not record ECC support as enabled, despite its server positioning. The Intel chip lists dual-channel memory but no memory type. The Intel part includes integrated graphics (Intel HD 3000), while the Opteron has none. The Opteron's socket is AMD Socket C32, the Intel chip uses Intel BGA 1224, meaning the Intel part is soldered to the motherboard rather than socketed.

Head-to-Head Benchmarks

The five recorded head-to-head results are all Cinebench tests, and all five favor the Intel Core i7-2720QM. The largest margin is in Cinebench R20 single-core, where Intel leads 202 to 196, a 3% difference. The smallest margin is in Cinebench R15 multi-core, where Intel leads 344 to 335, a 2.6% gap.

In Cinebench R20 multi-core, the Intel chip scores 1435 against the Opteron's 1396, a 2.7% advantage. The R23 multi-core test shows 3417 versus 3324, again 2.7%. Single-core R23 shows 482 versus 469, a 2.7% gap. These are extraordinarily consistent margins across different workload generations, suggesting the performance relationship between these two architectures is stable regardless of the Cinebench version.

What the data does not show is any test where the Opteron wins. The wins counter is 0 for AMD and 5 for Intel. However, the narrow margins mean the Opteron is never embarrassed. In absolute terms, the difference between 3324 and 3417 points in R23 multi-core is well within run-to-run variance for many systems. The recorded data is definitive, but the practical difference for a user would be barely perceptible.

The Opteron's higher core count (6 versus 4) does not yield a win in any multi-core test. This is the most striking finding. Piledriver's shared floating-point units and weaker per-core throughput appear to negate the two-core advantage. Meanwhile, the Intel chip's hyper-threading (8 threads versus 6) helps it close the core-count gap while maintaining superior single-thread performance.

Specification Differences

The two processors differ in almost every major specification category:

• Cores: AMD has 6, Intel has 4
• Threads: AMD has 6, Intel has 8
• Base clock: AMD at 3.00 GHz, Intel at 2.20 GHz
• Boost clock: AMD at 3.70 GHz, Intel at 3.30 GHz
• TDP: AMD at 65 watts, Intel at 45 watts
• Socket: AMD Socket C32 versus Intel BGA 1224
• Architecture: Piledriver versus Sandy Bridge
• Codename: Seoul versus Sandy Bridge
• Transistors: 1,200 million versus 1,160 million
• Die size: 315 mm² versus 216 mm²
• L1 cache: 288 KB total versus 64 KB per core
• L2 cache: 6 MB versus 256 KB per core
• L3 cache: 8 MB shared versus 6 MB shared
• Memory support: DDR3 recorded for AMD, not recorded for Intel
• Memory bus: Not recorded for AMD, dual-channel for Intel
• Integrated graphics: None for AMD, Intel HD 3000 for Intel
• Market segment: Server/Workstation versus Mobile
• Production status: Not recorded for AMD, end-of-life for Intel
• Release date: December 2012 for AMD, January 2011 for Intel
• Part number: OS4332OFU6KHK versus SR00W

The release dates are notable: the Intel chip launched nearly two years earlier, yet still outperforms the AMD part in every recorded test. This speaks to the architectural lead Intel held during that period. The Opteron's larger die and higher transistor count do not translate into a performance advantage, reinforcing the efficiency gap between the two designs.

Where Each One Wins

The Intel Core i7-2720QM wins every recorded benchmark, but the real story is in the context of those wins. In single-core performance, the Intel chip's lead is 3% in R20 and 2.7% in R23. This matters for lightly threaded workloads such as older games, spreadsheet calculations, or single-threaded database queries. The higher per-core efficiency of Sandy Bridge, despite the lower clock speed, is the deciding factor.

In multi-core performance, the Intel chip wins by 2.6% to 2.7% across R15, R20, and R23. This is a significant finding because the Opteron has two additional physical cores. For workloads that scale with thread count, the Opteron's 6 threads versus Intel's 8 threads means the Intel chip has a thread advantage as well. However, the narrow margins suggest that for heavily threaded server workloads, the Opteron is not far behind. The Opteron's higher base clock (3.00 GHz versus 2.20 GHz) and boost clock (3.70 GHz versus 3.30 GHz) partially compensate for weaker per-core execution.

The AMD Opteron 4332 HE wins in platform suitability for server deployments. It uses Socket C32, which supports dual-socket configurations in many server boards. Its 65-watt TDP is high for a mobile chip but moderate for a server part. The lack of integrated graphics is actually a benefit in servers where discrete management controllers or GPUs handle display output. The Intel Core i7-2720QM wins in mobile scenarios, with its 45-watt TDP, integrated Intel HD 3000 graphics, and BGA 1224 form factor designed for laptops.

For a server workload that is heavily multi-threaded and can use all available cores, the Opteron's 6-core design at 3.7 GHz boost is competitive, trailing by less than 3% despite the architectural disadvantages. For any workload where single-thread performance matters, the Intel chip's consistent 3% lead makes it the stronger choice. The data suggests that a system builder choosing between these two chips should base the decision on socket and platform requirements, not on performance, because the performance gap is too small to be decisive.
