AMD Athlon 64 X2 4000+ EE

The subject of this entry is the AMD Athlon 64 X2 4000+ EE, a desktop processor from AMD in the Athlon 64 X2 (Windsor) generation. The record lists a K8 architecture, an AMD Socket AM2 package, 2 cores, 2 threads, and a 2000.00 base clock with no boost clock. It carries a 65 TDP, is built on a 90 nm process with 154 million transistors on a 220 mm² die, and has a 256 KB L1 cache and a 1 MB L2 cache with no L3 listed. The memory bus is dual-channel, ECC support is false, PCIe is Gen 2, and integrated graphics are described as a chipset feature on certain motherboards. The production status is end-of-life, the release date is 2006-05-22, and the part number is ADO4000IAA6CS. The database data contains an empty benchmarks array, an average benchmark score of 0, a 50th percentile rank among all CPUs, and an empty nearestRivals array.

Single-Thread vs Multi-Thread Behavior — what the split means for real workloads

With 2 cores and 2 threads, the processor presents a one-to-one thread-to-core ratio. No extra threads are listed, so the maximum hardware scheduling width in this record is 2 threads. The boost clock field is null, meaning there is no separate higher frequency for single-thread operation; the only frequency value is the 2000.00 base clock. Consequently, the data does not show a frequency advantage for lightly threaded workloads. Single-thread tasks can use one core, while multi-thread tasks can occupy both cores, but the record offers no measured scores to quantify how those workloads scale.

The lack of benchmark data is decisive for this section. The benchmarks array is empty, and the avgBenchmarkScore is 0, so no per-thread or per-core scores exist. There are no scaling percentages, no application results, and no synthetic test results. The only structural points are the 2 cores, 2 threads, 2000.00 base clock, 256 KB L1, 1 MB L2, and the absence of an L3 cache. The cache values are listed without a per-core qualifier in the FACT PACK, so this analysis does not assign them to individual cores. In real workloads, the processor would have two execution contexts available; the behavior of a given workload would depend on whether it can use both threads. The data, however, does not provide any measured multi-thread efficiency or single-thread efficiency. The K8 architecture, Windsor codename, and Athlon 64 X2 (Windsor) generation define the design family, but they do not replace benchmark results.

Power and Thermals — TDP class, what cooling tier it implies

The only power figure in the record is the TDP of 65. This places the Athlon 64 X2 4000+ EE in a thermal class that is modest rather than extreme. The 90 nm process node is the manufacturing context for that TDP; the 154 million transistors are spread across a 220 mm² die. These manufacturing figures do not by themselves establish a cooling solution, but they do define a thermal envelope. The 65 TDP class implies a mainstream cooling tier rather than a high-power enthusiast tier, and the record contains no cooler specification that would raise that requirement.

No thermal measurements are present. There are no temperature values and no cooler specification beyond the 65 TDP. The production status is end-of-life and the release date is 2006-05-22, but neither lifecycle field adds thermal data. The multiplier is not unlocked, so the 2000.00 base clock is not meant to be raised through the multiplier according to this record; that further suggests a conservative operating envelope. Because the processor has only 2 cores and no boost clock, the sustained frequency is the 2000.00 base clock. The combination of a 65 TDP, 2 cores, a 2000.00 base clock, and a 90 nm process points to a cooling requirement that can be met by conventional desktop cooling, although the database does not list a specific cooler class.

Platform and Compatibility — socket, memory support, PCIe, upgrade path

The platform is defined by AMD Socket AM2. The architecture is K8, the codename is Windsor, and the generation is Athlon 64 X2 (Windsor). The market segment is Desktop, so the platform target is desktop systems. The memory-related fields are limited: memorySupport is null, so the record does not list memory types, capacities, or speeds. The memory bus is dual-channel, and ECC memory support is false. No memory bandwidth value is present, so the throughput of the dual-channel bus is not quantified in the data.

PCIe is listed as Gen 2. No lane count is given, so expansion bandwidth cannot be calculated from the record. Integrated graphics is listed as "On certain motherboards (Chipset feature)", meaning the display capability is attributed to a motherboard chipset rather than to the processor package. The processor itself is not credited with integrated graphics in the data.

Upgrade path information is sparse. The production status is end-of-life, and the release date is 2006-05-22. The record does not list any other Socket AM2 processors, so no direct upgrade path or compatible CPU family beyond the stated generation is documented. The part number ADO4000IAA6CS identifies the SKU. The multiplier is not unlocked, so frequency adjustment via an unlocked multiplier is not indicated. The series field is null, and the foundry field is null, so those platform descriptors are absent. The socket, PCIe generation, memory bus, and chipset-based graphics are the only compatibility facts in the record.

How It Compares — position vs each nearest rival, one short paragraph per rival

The nearestRivals array is empty. As a result, there are no nearest rival names, no rival scores, and no deltaPct values in this entry. The section for per-rival comparison cannot be populated with rival paragraphs because the record does not contain any direct competitor entries.

The only comparative indicator is the percentileVsAllCpus field, which is 50. A value of 50 places this processor at the midpoint of the CPU distribution in the database. This is a global rank, not a score, and it does not reveal whether the processor is ahead of or behind any specific rival. The empty nearestRivals array means the database has not attached a peer set to this processor.

In the absence of rivals, the comparison context is limited. The processor's characteristics are: AMD Socket AM2, K8 architecture, Windsor codename, Athlon 64 X2 (Windsor) generation, 2 cores, 2 threads, 2000.00 base clock, no boost clock, 65 TDP, 90 nm process, 154 million transistors, 220 mm² die, 256 KB L1, 1 MB L2, dual-channel memory bus, no ECC, PCIe Gen 2, and chipset-based integrated graphics on certain motherboards. These are the facts that a comparison would use, but no comparison data exists. The 50th percentile is the only placement, and it is a median placement rather than a leading or trailing one.

Benchmark Performance — analyze scores vs rivals with exact % deltas

There are no exact percentage deltas to analyze in the Benchmark Performance section. The nearestRivals array is empty, so no deltaPct values exist. The benchmarks array is empty, so no individual run scores exist. The avgBenchmarkScore is 0, which is a numeric value in the record but is not accompanied by any underlying benchmark entries. Without underlying entries, the 0 cannot be verified as a computed average; it functions as a placeholder in the data.

The only frequency value is the 2000.00 base clock. The boost clock is null, so no higher frequency is documented. With 2 cores and 2 threads, the processor can address at most two execution contexts, but the record does not provide a measured multi-thread score. The cache hierarchy is 256 KB L1, 1 MB L2, and no L3; these are structural memory figures, not performance results. The memory bus is dual-channel, but no bandwidth figure is present. The process node is 90 nm, the transistor count is 154 million, and the die size is 220 mm²; these manufacturing data do not yield a score.

The only quantitative placement is the 50th percentile. This rank says that the processor sits in the middle of all CPUs in the database, but it does not provide a percentage difference from any rival. Because no rivals are listed, no exact percentage deltas can be stated. The avgBenchmarkScore of 0 should not be read as a zero-performance result; it is the score field associated with an empty benchmark set. Therefore, the benchmark performance of this processor cannot be evaluated from the FACT PACK. The data supports structural analysis only.
