AMD Opteron 2347

Benchmark Performance

The AMD Opteron 2347 presents an unusual benchmark profile: its average benchmark score sits at 0, and its percentile ranking against all CPUs in the database is exactly 50. This combination indicates that the part occupies a middle-ground position in the overall performance distribution, though the absence of individual benchmark scores means the data cannot confirm specific workload strengths or weaknesses. The 50th percentile placement suggests that roughly half of all recorded CPUs perform better and half perform worse, placing this Opteron squarely in the mainstream of the database's historical records.

The processor's specification sheet reveals why its aggregate score might land in this neutral zone. With four cores and four threads operating at a base clock of 1900.00 MHz, the Opteron 2347 is a modestly configured server part from the Barcelona generation. The lack of a boost clock means the processor runs at a fixed frequency, never exceeding that 1900.00 MHz ceiling regardless of thermal headroom or workload demand. This fixed-clock behavior typically produces consistent but unexceptional results across both lightly threaded and fully threaded applications.

The cache hierarchy shows a deliberate balance: 64 KB of L1 per core, 512 KB of L2 per core, and a shared 2 MB L3 cache. The L3 allocation of 2 MB shared across four cores works out to 512 KB per core, which is a relatively small pool by modern standards but was appropriate for the 65 nm process node. The 463 million transistors packed into a 285 mm² die suggest a design that prioritized manufacturing efficiency over raw transistor count, which aligns with the processor's mid-pack percentile ranking.

How It Compares

The FACT PACK includes no nearestRivals data for the AMD Opteron 2347, which means the database contains no direct comparison points from contemporaneous or competing processors. This absence is itself informative: it suggests the part was either too niche for sustained benchmarking or that its performance profile did not generate enough competitive interest to warrant side-by-side evaluation. Without rival scores or deltaPct values, any claims about relative performance would be speculative, and the data does not support such assertions.

The lack of rivals also means the 50th percentile cannot be contextualized against specific competitors. Typically, a server processor from 2007 would be compared against other dual-socket-capable parts from Intel or earlier AMD Opteron generations, but the database has not recorded those matchups for this unit. The benchmark results indicate that this Opteron simply exists as a standalone data point, occupying the median position without any nearby reference points to sharpen its profile.

Power and Thermals

The Opteron 2347 carries a TDP of 95 watts, which places it in a moderate power envelope for a server processor of its generation. This TDP class implies that a capable air cooler with a standard server-grade heatsink would be sufficient for normal operation, given the fixed 1900.00 MHz clock speed generates a predictable thermal load. The 95-watt figure is notable because it sits below many workstation parts of the era, suggesting the design prioritized power efficiency over peak performance.

The 65 nm process node contributes to this thermal profile. Smaller process nodes typically reduce leakage current and switching losses, which helps keep power draw manageable even at higher transistor counts. The 463 million transistor count, while substantial for 2007, is spread across a 285 mm² die that allows for adequate heat spreading. The cooling tier implied by the 95-watt TDP is a standard server heatsink with a low-profile fan, not the oversized tower coolers or liquid cooling systems required by higher-TDP parts.

Who Should Consider It

Given the benchmark data shows this processor at the 50th percentile with a zero average score, the target audience is narrow and specific. Server and workstation environments that require ECC memory support would find the Opteron 2347 suitable, as the memory controller supports ECC DDR2 modules. The dual-channel memory bus with 10.7 GB/s bandwidth provides adequate throughput for memory-sensitive workloads like database transactions or virtualization hosts, though the lack of benchmark scores means the practical impact of this bandwidth cannot be quantified.

Office productivity workloads that are lightly threaded would run adequately on the 1900.00 MHz base clock, but the absence of a boost clock means single-threaded responsiveness is capped at that frequency. For gaming, the four cores without SMT and the modest clock speed would likely produce underwhelming results, and the server market segment designation reinforces that this is not a gaming-oriented part. Content creation workloads that scale across multiple cores would benefit from the four physical cores, but the 2 MB shared L3 cache might become a bottleneck in larger datasets.

FAQ

Q: What is the production status of the AMD Opteron 2347?

A: The production status is listed as End-of-life, indicating the processor is no longer manufactured or sold through official channels.

Q: Does the Opteron 2347 support ECC memory?

A: Yes, ECC memory support is listed as true, which is a critical feature for server and workstation reliability.

Q: What is the memory bandwidth of this processor?

A: The memory bandwidth is rated at 10.7 GB/s, delivered through a dual-channel DDR2 memory bus.

Q: How many cores and threads does the Opteron 2347 have?

A: It has 4 cores and 4 threads, with no SMT or Hyper-Threading capability.

Q: What socket does this processor use?

A: It uses AMD Socket Fr2, which is specific to the Barcelona generation of Opteron processors.

Q: Is the multiplier unlocked for overclocking?

A: No, the multiplier is locked, so the base clock of 1900.00 MHz cannot be adjusted through multiplier changes.

Single-Thread vs Multi-Thread Behavior

The Opteron 2347's architecture reveals a clear split between single-thread and multi-thread behavior, though the benchmark data does not provide direct scores for either category. The 1900.00 MHz base clock with no boost capability means single-thread performance is strictly limited by that frequency, and the 64 KB L1 cache per core is small enough that latency-sensitive single-threaded code may not find sufficient cache residency. The 512 KB L2 per core is more generous and likely helps mitigate some of the clock speed disadvantage.

Multi-threaded behavior is governed by the four physical cores operating at the same fixed frequency. The shared 2 MB L3 cache is the key differentiator: when all four cores are active, they must compete for this relatively small pool, which could lead to cache thrashing in workloads with large working sets. However, the absence of SMT means there is no contention between logical threads on the same physical core, so each thread gets dedicated execution resources. The 65 nm process node and 463 million transistors suggest that the design team allocated die area to four complete cores rather than adding SMT logic, which favors multi-threaded throughput over single-thread efficiency.

For real workloads, this split implies that legacy server applications with many independent threads would utilize all four cores effectively, while modern applications that rely on high single-thread performance would see the 1900.00 MHz cap as a limiting factor. The 50th percentile ranking likely reflects this balanced but unremarkable profile.

Platform and Compatibility

The Opteron 2347 is built for the AMD Socket Fr2 platform, which is associated with the Barcelona generation of Opteron processors. The architecture is listed as Zen 3, though this designation appears inconsistent with the Barcelona codename and 65 nm process node, which historically correspond to a pre-Zen design. The platform supports DDR2 memory, with the specific memory configuration depending on the motherboard selected. The memory bus is dual-channel, providing 10.7 GB/s of bandwidth.

PCIe support is not listed in the data, which means the platform's expansion capabilities cannot be characterized with numbers. The lack of integrated graphics confirms this is a processor-only part requiring a discrete GPU for display output. The upgrade path is inherently limited by the Socket Fr2 platform, which is tied to the Barcelona generation; users cannot install newer AMD processors without changing motherboards. The ECC memory support and server/workstation market segment indicate the platform was designed for reliability-focused deployments rather than consumer desktops. The launch MSRP is $316, which positioned it as a mid-range server processor at its 2007 release.
