About AMD Athlon 64 LE-1640B

The AMD Athlon 64 LE-1640B is a desktop processor built on AMD’s K8 architecture with the codename Lima and the Athlon 64 (Lima) generation label. It has one core and one thread, runs at a 2.70 GHz base clock, and lists no boost clock. The database record contains no benchmark runs, so the strongest available comparative fact is the 50th percentile rank against all CPUs. This is an end-of-life desktop part released on April 27, 2008.

Benchmark Performance

The benchmark results array is empty. The average benchmark score is 0, and the nearestRivals list is empty, so no exact percentage deltas exist for this SKU. There are no named rivals and no deltaPct values to analyze. The only aggregate figure in the FACT PACK is percentileVsAllCpus at 50, which places the processor at the midpoint of the database’s CPU population. Because there are no measured scores, that rank is the only quantitative performance indicator; it cannot be expressed as an advantage or deficit against any specific rival.

Without benchmarks, the performance discussion is necessarily limited to the documented configuration. A single core and a single thread mean the processor has no parallel execution resources. The 2.70 GHz base clock is the only clock value in the record, and no boost clock is listed. The cache hierarchy consists of 128 KB of L1 and 512 KB of L2, with no L3 cache. The 65 nm process node, 122 million transistors, and 77 mm² die size complete the physical profile. The 0 benchmark score, when combined with the empty results array, should be interpreted as an absence of data rather than as a measurement of zero output. In the database as provided, the Athlon 64 LE-1640B has no verifiable benchmark performance.

Single-Thread vs Multi-Thread Behavior

With one core and one thread, the single-thread/multi-thread split does not exist in the usual sense. The processor can execute only one instruction stream at a time. Every workload that runs on it is effectively a single-thread workload, and there is no second thread to offload independent work. The 2.70 GHz base clock is therefore the primary determinant of execution pace. The absence of a boost clock means no higher-frequency mode is documented for bursty single-thread activity.

For real software, the practical effect is that multi-threaded applications will not gain any parallel scaling from this chip. They will instead serialize their work onto the sole logical processor. The 512 KB L2 cache gives the single thread a modest working data buffer, while the 128 KB L1 cache handles near-term data. The lack of L3 cache means there is no large shared cache between additional cores, but that is moot because there is only one core. The record supports a simple verdict: this is a strictly single-threaded execution engine.

How It Compares

The nearestRivals field is empty. No direct rival is named, and no rival score or percentage delta is provided. No direct comparison is possible from the pack. The only global comparison point in the data is the 50th percentile, which indicates the entry sits at the middle of the all-CPU ranking when benchmark records are absent. In practical terms, the lack of rival data forces a comparison based on the processor’s own characteristics: a single-core K8 part with a 45W TDP, DDR2 support, socket AM2, and end-of-life status. There is no measured competitive distance to any other CPU in this FACT PACK.

Who Should Consider It

Because the average benchmark score is 0 and no workload scores are recorded, recommendations must be grounded in the core, thread, and clock specifications rather than measured results. For office use, a single 2.70 GHz core can handle basic sequential desktop tasks in principle, but the pack does not verify any particular application performance. For gaming, the data provides no benchmark support; the processor also has no on-die graphics, because integrated graphics appear only as an optional chipset feature on certain motherboards. For creation workloads such as rendering or compilation, the one-core/one-thread design would not scale across parallel processor cores, and no multi-core advantage is possible.

The 45W TDP and AM2 socket make the part a plausible candidate for legacy low-power desktop systems. The “Desktop” market segment label aligns with that role. The end-of-life production status means it is not a current platform choice. The locked multiplier further limits enthusiast tuning. A user pairing this CPU with a motherboard that provides chipset graphics could avoid a separate display adapter, but that depends on the specific board, not on the processor. Ultimately, the database suggests it is a simple, low-power single-thread CPU for light or legacy desktop workloads; no benchmark score exists to recommend it for demanding gaming or multi-threaded creation.

Power and Thermals

The TDP is 45W. That is the sole power figure in the FACT PACK, and it places the part in the low-power desktop range. A 45W single-core processor at 2.70 GHz with no boost clock implies a light cooling burden. The 65 nm manufacturing process, 122 million transistors, and 77 mm² die are the physical details behind that thermal profile. The pack does not list a cooler, thermal wattage, or cooling class, so a specific cooler size cannot be stated. The implied cooling tier is a basic desktop heat sink appropriate for an AM2 socket. The locked multiplier means the user cannot easily raise clocks to increase heat output, which reinforces the low-power character of the part. No measured thermal data is present.

Platform and Compatibility

The socket is AMD Socket AM2. Memory support is DDR2, and the memory bus is dual-channel. ECC memory is not supported. The PCIe interface is Gen 2. Integrated graphics are not on the processor die; the FACT PACK states that they are available “On certain motherboards (Chipset feature)”. That makes the motherboard and chipset responsible for display output if integrated video is used. The release date is April 27, 2008, and the production status is end-of-life. The multiplier is not unlocked, and the part number is ADH164BIAA4DP.

The platform’s upgrade path is not documented in the FACT PACK. No other AM2 processors are listed for comparison or compatibility. The end-of-life status means this SKU is no longer in production. The absence of a boost clock and the locked multiplier both limit overclocking and performance tuning. The memory interface is dual-channel DDR2, with no memory bandwidth number supplied. For anyone assembling or maintaining an AM2-era desktop, this processor’s compatibility details are the relevant facts: AM2, DDR2, PCIe Gen 2, no ECC, and chipset-dependent integrated graphics.
