About AMD Athlon 64 X2 5400+
The AMD Athlon 64 X2 5400+ is a desktop processor from AMD, built around the K8 architecture in the Windsor generation. It is a dual-core, dual-thread part with a fixed 2.80 GHz base clock and no boost clock. The FACT PACK lists 2 cores, 2 threads, AMD Socket AM2, an 89 W TDP, a 90 nm process node, 154 million transistors, a 220 mm² die, 256 KB of L1 cache, 512 KB of L2 cache, no L3 cache, a dual-channel memory bus, PCIe Gen 2, and no ECC support. The production status is end-of-life, and the release date is 2006-12-11.
Single-Thread vs Multi-Thread Behavior
Because the core count equals the thread count, the processor offers exactly two hardware execution threads to software. There are no additional logical threads beyond the two cores. A single-threaded workload has one K8 core at 2.80 GHz, while a two-thread workload can occupy both cores. The absence of a boost clock means the 2.80 GHz operating point is also the maximum advertised frequency; software does not receive a transient high-frequency state for bursty sequential code.
In single-thread-heavy applications, the relevant characteristics are therefore the K8 microarchitecture, the 2.80 GHz base clock, and the cache hierarchy. The cache consists of 256 KB of L1 and 512 KB of L2, with no L3. Workloads that fit within the L1/L2 caches keep their working set close to the cores, whereas workloads with larger working sets must use the dual-channel memory bus because there is no L3 to absorb misses. Multi-threaded workloads are bounded by two threads; any code that needs more concurrent threads will be queued behind the two available execution threads. The dual-channel memory bus is the only memory-related platform detail recorded in the data, so data-heavy parallel performance is partially shaped by that bus. The multiplier is not unlocked, which constrains user-controlled clock adjustments.
For real workloads, this split means latency-sensitive single-threaded code relies entirely on the K8 core’s clock speed and cache behavior, while parallel workloads gain from the second core but are capped at two threads. The K8 architecture and Windsor codename identify the generation. The absence of L3 distinguishes this cache layout from processors that include an L3 cache. In summary, the single-thread versus multi-thread distinction here is simple: one thread per core, no boost state, a 2.80 GHz ceiling, and a maximum of two concurrent threads.
Power and Thermals
The thermal design power is 89 W, which sets the cooling requirement for sustained operation. The processor is manufactured on a 90 nm process, with 154 million transistors on a 220 mm² die. These physical characteristics contribute to the thermal density of the chip. Since there is no boost clock, the thermal profile has no higher-frequency state to provision for; the 2.80 GHz base clock is the only clock state in the data.
The integrated graphics field is described as “On certain motherboards (Chipset feature)”, which means display functionality comes from the motherboard chipset on certain boards rather than from the CPU die. As a result, any graphics power draw is separate from the 89 W CPU TDP. ECC memory is not supported, which is a platform memory characteristic but not a thermal factor. The dual-channel memory bus is present, although memory bandwidth is not listed in the data. The 89 W TDP class implies a capable air cooler is sufficient; the data does not require a larger cooling solution. The production status is end-of-life, so the thermal specification is fixed for this entry. The Socket AM2 package is the socket interface, and the desktop market segment determines the expected system context. In thermal terms, the processor is a dual-core 90 nm part with a moderate TDP, a locked multiplier, and no boost-dependent cooling headroom.
Benchmark Performance
The benchmark records for this processor are empty. The average benchmark score is 0, which corresponds to no populated measurements rather than a measured result of zero. The percentile-vs-all-CPUs field is 50, placing this processor at the middle of the dataset’s CPU distribution. However, because the benchmarks array is empty, the percentile is not backed by a visible test score in this entry. The nearestRivals list is also empty, so there are no exact percentage deltas to compute against other processors. As a result, statements like “X% ahead of a rival” are not possible from this FACT PACK.
What can be stated with certainty are the structural parameters: 2 cores, 2 threads, 2.80 GHz base clock, no boost clock, 256 KB of L1 cache, 512 KB of L2 cache, no L3 cache, and a dual-channel memory bus. These parameters define the potential performance envelope but are not benchmark scores. The K8 architecture and Windsor codename identify the microarchitecture generation. The processor uses a 90 nm process and has 154 million transistors on a 220 mm² die, which are manufacturing facts rather than runtime measurements. The PCIe interface is Gen 2, which characterizes the available platform connectivity. The market segment is Desktop, and the production status is end-of-life. The part number ADA5400IAA5CZ identifies the specific SKU. Without benchmark entries, the only directly listed performance-position value is the 50th percentile rank, and that rank should be interpreted as a positional placeholder in the absence of score data.
How It Compares
The nearestRivals array in the FACT PACK is empty, so this processor has no listed direct competitors. Consequently, no per-rival paragraphs can be written, because no rival names, scores, or delta percentages are available. The only positional comparison in the data is the percentileVsAllCpus value of 50. This places the part in the middle of the CPU distribution, but it does not indicate which specific CPUs are around it. A median percentile with zero populated benchmark scores is a coarse positional signal, not a head-to-head comparison.
The K8 architecture, Windsor generation, and Socket AM2 platform are the context that would distinguish this part from CPUs on other sockets, but no such rivals are named. The 2-core/2-thread configuration and 2.80 GHz base clock would be the primary comparison metrics if rival data existed. The 89 W TDP and 90 nm process are also listed differentiators, but without nearestRivals they cannot be converted into percentage gaps. With no rival entries, no percentage differences can be calculated from this FACT PACK.
