AMD Phenom II X6 1100T BE

The AMD Phenom II X6 1100T BE is a six-core desktop processor built on the K10 architecture (codename Thuban) and fabricated on GlobalFoundries' 45 nm process. It operates at a base clock of 3.30 GHz and a boost clock of 3.70 GHz, with a TDP of 125 W. The processor is recorded in the database at the 50th percentile of all CPUs, indicating a median position in overall performance distribution, though no benchmark scores are listed for this part. It supports DDR2 and DDR3 memory in a dual-channel configuration, has 6 MB of shared L3 cache, and features an unlocked multiplier as part of its Black Edition designation. Released in December 2010, it occupies the AMD Socket AM3 and is now marked as end-of-life.

Benchmark Performance

The database contains no benchmark scores for the AMD Phenom II X6 1100T BE; the avgBenchmarkScore field is 0, and the nearestRivals list is empty. Consequently, direct performance comparisons against specific competitor models are impossible, and no delta percentages can be computed. The only quantitative performance indicator is the percentile rank of 50, which places this processor exactly at the midpoint of all CPUs recorded in the database. This median position implies that half of the tracked processors are faster and half are slower, but without a distribution of scores, the practical meaning of that rank remains abstract. The lack of benchmark data means that any performance assessment must be inferred from the architectural parameters: six physical cores, six threads (no SMT), a base clock of 3.30 GHz, and a boost clock of 3.70 GHz. These figures suggest a processor designed for multi-threaded workloads, but the absence of measured results precludes a quantitative evaluation of its throughput or latency characteristics. The 50th percentile rank does, however, indicate that the processor is not an outlier in either direction; it sits comfortably within the mainstream of the database's historical CPU population, which is consistent with a high-core-count part from its generation.

Single-Thread vs Multi-Thread Behavior

The Phenom II X6 1100T BE implements six cores and six threads, meaning each core handles exactly one thread without simultaneous multithreading. This design favors workloads that can scale across multiple cores, as all six cores are available for parallel execution. The base clock of 3.30 GHz and boost clock of 3.70 GHz are relatively high for a six-core processor, suggesting that both single-thread and multi-thread tasks can benefit from the high frequency. However, the K10 architecture's instruction-per-clock (IPC) efficiency is not detailed in the data, so the raw clock speed alone does not define single-thread performance. The cache hierarchy provides a shared 6 MB L3 cache, with 512 KB of L2 and 128 KB of L1 per core, which helps reduce memory latency when multiple cores access common data. The memory subsystem, rated at 21.3 GB/s via dual-channel DDR2/DDR3, offers a moderate bandwidth that may become a limiting factor for heavily multi-threaded workloads that saturate memory traffic. The boost clock of 3.70 GHz is the maximum rated frequency, but the dataset does not specify whether this boost applies to a single core, all cores, or a subset. In practice, such boosts are often single-core or limited-core, but without explicit data, the exact behavior remains unknown. For workloads with more than six threads, the lack of SMT means that extra threads will contend for the same six cores, potentially causing scheduling overhead. Conversely, applications that are well-optimized for six threads can utilize the full core count, and the high clock speeds may offset some architectural inefficiencies.

How It Compares

The FACT PACK lists no nearest rivals for this processor, so a direct comparison with specific competitor models cannot be made. The only positional reference is the 50th percentile across all CPUs in the database, which indicates that the Phenom II X6 1100T BE sits exactly at the median of the recorded performance distribution. Without rival scores or delta percentages, any further comparative analysis would be speculative. The absence of rival entries means the database does not offer a basis for assessing this processor's standing against contemporaneous parts from Intel or other vendors. The architectural data—six cores, 3.30–3.70 GHz clocks, 6 MB L3 cache, and dual-channel memory support—suggests a high-end desktop processor of its era, but the lack of benchmark results prevents a definitive ranking. The 50th percentile rank, while useful as a broad indicator, does not convey how the processor performs relative to specific models, nor does it provide insight into its strengths or weaknesses in particular workload classes.

Power and Thermals

The TDP of the AMD Phenom II X6 1100T BE is rated at 125 W. This is a high power envelope, indicating that the processor demands a substantial cooling solution to maintain stable operation under load. The 45 nm process node, combined with a die size of 346 mm² and 904 million transistors, contributes to a significant thermal density that must be managed effectively. The processor is not a low-power part; it is designed for desktop systems with robust thermal provisions. The unlocked multiplier allows for overclocking, which would increase power consumption and heat output beyond the rated TDP, so the cooling solution should have headroom to accommodate such adjustments. The memory bandwidth of 21.3 GB/s, delivered via dual-channel DDR2/DDR3, does not impose a major thermal burden, as memory controllers are integrated but typically generate less heat than the compute cores. The processor lacks integrated graphics, relying on a chipset feature on certain motherboards for video output; this means the CPU's thermal load is entirely attributable to the compute cores, simplifying cooling design. The 125 W TDP class implies that a high-end air cooler or a liquid cooling solution is appropriate, though the exact cooler size is not specified in the data. Given the end-of-life production status, availability of compatible cooling solutions may vary, but the thermal requirements remain defined by the 125 W rating.
