AMD Opteron 8346 HE (B3)

The AMD Opteron 8346 HE (B3) is a 4-core, 4-thread Server/Workstation processor from AMD. The data lists its base clock at 1800.00 MHz and provides no boost clock. The architecture field is Zen 3, the codename is Barcelona, and the generation is Opteron (Barcelona). The chip is built on a 65 nm process, contains 463 million transistors on a 285 mm² die, and carries a 68 W TDP. It uses AMD Socket Fr2. The launch MSRP is $698.

Who Should Consider It

This is a server/workstation part, not a consumer desktop processor. It has no integrated graphics listed, so any video output requires a separate graphics device. With 4 cores and 4 threads, the processor can run only four concurrent threads. That thread ceiling makes it a candidate for workloads that fit within four threads, but not for workloads that scale beyond them.

The dataset contains no benchmark entries and reports an average benchmark score of 0. There are no positive scores for gaming, office, or creation workloads to cite. The 50th percentile rating among all CPUs places the part at the midpoint of the database distribution, not in a high-performance tier. For gaming, the absence of integrated graphics and the lack of any game benchmark data mean the database offers no evidence that it is suited to that role. A discrete GPU would be required for any display output, and the 4-thread design would be the ceiling for game-related processing.

For office-style productivity, the relevant features are the 1800.00 MHz base clock, 4 cores, and per-core cache. Those features could support lightly threaded office work, but no benchmark score confirms any specific application behavior. For creation workloads, the restriction is more severe. The average benchmark score is 0, and the dataset shows no rendering, encoding, or compilation scores. The 50th percentile ranking does not suggest top-end performance. The strongest listed attributes for the intended market segment are ECC memory support, dual-channel DDR2 memory, and a 2 MB shared L3 cache. Those are reliability and server-oriented features rather than gaming or high-end creation features.

The data therefore points toward a narrow recommendation: legacy server or workstation systems on Socket Fr2 that need ECC DDR2 memory, four processing threads, and a 68 W TDP envelope. The processor is not presented by the data as a high-score gaming chip or a multi-threaded creation powerhouse.

Power and Thermals

The TDP is 68 W. That is the only power figure recorded, and it defines the thermal class of the processor. A 68 W TDP implies a modest cooling tier; the data does not specify any particular cooler, but this power level is not in the range that would demand exotic cooling hardware. There is no boost clock listed, so there is no turbo frequency to consider for transient power beyond the 1800.00 MHz base operating point.

The physical information in the dataset supports that thermal profile. The process node is 65 nm, the transistor count is 463 million, and the die size is 285 mm². The combination of four cores and a 65 nm process is the recorded basis for the 68 W figure. No separate thermal limits beyond TDP are provided. The production status is end-of-life, so the thermal and power characteristics are historical specifications rather than active product claims.

Platform and Compatibility

The processor uses AMD Socket Fr2. Memory support is DDR2, and the dataset notes that memory support depends on the motherboard. The memory bus is dual-channel, with a listed memory bandwidth of 10.7 GB/s. ECC memory is supported, which matters for server and workstation workloads that need memory error checking.

No PCIe information is recorded in the dataset. No integrated graphics is listed. Expansion and display capabilities are therefore left to the motherboard and add-in cards. The multiplier is locked, so the 1800.00 MHz base clock is the fixed operating point according to the data; no overclocking support is listed. The part number is OS8346PAL4BGH. The release date is 2008-04-30, and the production status is End-of-life. No series name is recorded, and no foundry is recorded.

The upgrade path is constrained by the platform data. The socket is AMD Socket Fr2, and the production status is end-of-life. The dataset does not list a successor processor or a forward upgrade route. Compatibility is tied to Socket Fr2 boards, and memory support is tied to motherboard DDR2 capability. The locked multiplier and absent boost clock also limit any performance adjustment flexibility.

How It Compares

The data includes no nearestRivals entries. There are no rival names, no comparison scores, and no deltaPct values to report. The only comparative metric in the dataset is the percentile vs all CPUs, which is 50. That places the Opteron 8346 HE (B3) exactly at the midpoint of the database distribution.

The average benchmark score is 0, and the benchmark list is empty. Without benchmark scores or rival deltas, a numeric market-positioning statement cannot be made. What can be compared is the recorded feature set: 4 cores, 4 threads, 1800.00 MHz base clock, 68 W TDP, Socket Fr2, DDR2 memory support, dual-channel memory bus, 10.7 GB/s memory bandwidth, ECC memory, and a 2 MB shared L3 cache. No rival paragraphs can be written because the dataset supplies no rival entries for this processor.

Single-Thread vs Multi-Thread Behavior

The processor has 4 cores and 4 threads, so it does not support simultaneous multithreading. Multi-threaded workloads are limited to exactly one thread per core. The base clock is 1800.00 MHz, and there is no boost clock, so the single-thread frequency is the base frequency. The locked multiplier reinforces this fixed operating point.

The cache hierarchy is split between per-core and shared resources. Each core has 64 KB of L1 and 512 KB of L2. The L3 cache is 2 MB and shared across all cores. For single-thread workloads, a core can use its private L1 and L2 plus the shared L3. For multi-thread workloads, all four cores share the L3 and access the dual-channel 10.7 GB/s DDR2 memory path.

The dataset does not provide separate single-thread or multi-thread benchmark scores. The average benchmark score is 0, so there is no measured performance split to compare against other processors. The architecture is listed as Zen 3, but no per-clock performance metric is included. Based on the thread count, this is a four-concurrent-thread design with no boost headroom. Workloads that require more than four threads will not receive additional logical processors, because none are present. The shared 2 MB L3 can help cores cooperate, but the overall thread count remains the hard boundary for multi-threaded scaling.
