AMD Opteron 2347 HE

The AMD Opteron 2347 HE is a quad-core server/workstation processor from the Barcelona generation, built on a 65 nm process with 463 million transistors on a 285 mm² die. It runs at a fixed 1.90 GHz base clock with no boost capability, draws a 68 W TDP, and was released on September 9, 2007, with a launch MSRP of $377. Now end-of-life, the chip sits at the 50th percentile of all CPUs in the benchmark database — a median position that raises an immediate question: how does a 2007-era efficiency-tuned server chip hold the exact middle ground in a database spanning decades of processors?

How It Compares

The benchmark database lists no direct rivals for the Opteron 2347 HE, which is itself an informative data point. The nearestRivals field is empty, meaning no processor in the database falls close enough to this chip's benchmark profile to warrant a comparison entry. The 50th percentile placement, however, tells a story: this processor sits at the exact median of all CPUs tracked. For a part released in September 2007 with four cores at 1.90 GHz, occupying the midpoint of the entire database suggests that the database's population is heavily weighted toward older and lower-end parts — this Opteron is not at the bottom of the distribution.

The average benchmark score of 0, combined with an empty benchmarks array, indicates that no recorded benchmark runs exist for this specific part number. Its percentile ranking is therefore derived from its hardware characteristics rather than measured performance. This is a common situation for end-of-life server processors that never entered the database's benchmark submission pipeline.

Power and Thermals

The 68 W TDP immediately signals the "HE" (high efficiency) design philosophy. This is not a performance-maximized part; it is a power-optimized processor engineered for server environments where thermal output and energy consumption are operational costs. The 65 nm process node and 463 million transistor count on a 285 mm² die represent the physical implementation. At a fixed 1.90 GHz with no boost clock, the power draw is consistent and predictable — there are no turbo-induced thermal spikes to design around.

For cooling, a 68 W TDP part requires only a modest heatsink and fan assembly. Server chassis with constrained airflow can handle this thermal load without difficulty, and the consistent power profile simplifies thermal management in multi-socket configurations. The lack of a boost clock means sustained all-core operation at 1.90 GHz draws the same power as single-threaded operation, which is a distinct advantage for densely packed server racks.

Benchmark Performance

The benchmark data presents a paradox: a processor at the 50th percentile with an average benchmark score of 0. The benchmarks array is empty, so there are no measured scores to analyze. The percentile ranking is an interpolation based on specifications — 4 cores, 4 threads, 1.90 GHz, 2 MB shared L3 cache — placed against the database's full population of CPUs.

What does the data imply? A quad-core, quad-thread processor at 1.90 GHz with dual-channel DDR2 memory at 10.7 GB/s bandwidth lands at the median of all CPUs ever tracked. This suggests that the database's distribution includes a large population of modern high-core-count processors at the top, a long tail of legacy parts at the bottom, and this Opteron sitting precisely between them. The 2 MB shared L3 cache, alongside 64 KB L1 and 512 KB L2 per core, provides a cache hierarchy that was competitive for its era but is modest by modern standards.

Without recorded benchmark scores, percentage-based comparisons to rivals are impossible from this data. The 50th percentile is the only quantitative anchor, and it indicates a processor that is neither a standout nor a straggler — a balanced, mid-pack position.

Who Should Consider It

The Server/Workstation market segment and end-of-life production status make the Opteron 2347 HE a niche consideration. For those maintaining legacy server infrastructure, this processor offers ECC memory support — a non-negotiable feature for data integrity in database and file server roles. The dual-channel DDR2 memory interface, delivering 10.7 GB/s of bandwidth, is adequate for era-appropriate server workloads such as transaction processing, web serving, or network storage.

For office productivity, the four cores at 1.90 GHz can handle basic applications, but the absence of integrated graphics means a discrete GPU is mandatory for any display output. Gaming is firmly outside this processor's domain — the server-oriented architecture and modest clock speed preclude modern gaming performance. Creation workloads like video rendering or 3D modeling would be constrained by the four-thread limit, but the 68 W TDP makes the chip viable for always-on roles where power efficiency matters more than peak performance.

Single-Thread vs Multi-Thread Behavior

The Opteron 2347 HE's threading model is simple: four cores, four threads, no simultaneous multithreading. Each core executes exactly one thread, and multi-threaded throughput scales linearly with core count. There are no SMT efficiency gains, but also no SMT contention penalties — a clean, predictable execution model.

Single-threaded performance is entirely a function of the Barcelona core's instructions-per-clock efficiency at 1.90 GHz, since there is no boost clock to provide transient speed increases. The per-core cache allocation — 64 KB L1 and 512 KB L2 — gives each thread dedicated fast storage, while the 2 MB shared L3 cache facilitates inter-core communication. When one core writes data that another core reads, the L3 cache enables that sharing without falling back to the dual-channel DDR2 memory bus, which is the system's ultimate bottleneck at 10.7 GB/s.

Platform and Compatibility

The Opteron 2347 HE uses AMD Socket Fr2, a server socket specific to the Barcelona generation of Opteron processors. Memory support is DDR2, with the critical caveat that actual compatibility "depends on motherboard" — the server board's memory controller determines which DIMM types and speeds are supported. The dual-channel memory bus provides 10.7 GB/s of bandwidth, and ECC memory is supported, which is essential for error-tolerant server operation.

There is no integrated graphics, so a discrete GPU is required for any display output. PCIe information is not listed in the data, so expansion capabilities cannot be detailed. The multiplier is locked, preventing overclocking, and the part number OS2347PAL4BGE identifies the specific SKU. The architecture is listed as Zen 3 in the database, with the codename Barcelona — a pairing that reflects the database's classification of this chip. The processor is end-of-life, and the Socket Fr2 platform offers no forward upgrade path to later AMD server sockets; the platform is confined to the Barcelona generation.
