Athlon 64 LE-1620 Clock Speeds
Base and boost frequencies
Clock speed is a critical factor in Athlon 64 LE-1620 benchmark performance, measured in GHz. The base clock represents the guaranteed operating frequency, while the boost clock indicates maximum single-core performance under optimal conditions. Higher clock speeds translate to faster single-threaded performance, which is essential for gaming and applications that don't fully utilize multiple cores. The Athlon 64 LE-1620 by AMD can dynamically adjust its frequency based on workload and thermal headroom.
AMD's Athlon 64 LE-1620 Cache Hierarchy
L1, L2, L3 cache sizes
Cache memory is ultra-fast storage built directly into the Athlon 64 LE-1620 processor die. L1 cache provides the fastest access for frequently used data, while L2 and L3 caches offer progressively larger storage with slightly higher latency. Larger cache sizes significantly improve CPU benchmark scores by reducing memory access times. The Athlon 64 LE-1620's cache configuration is optimized for both gaming performance and productivity workloads, minimizing data fetch delays during intensive computations.

About AMD Athlon 64 LE-1620
The AMD Athlon 64 LE-1620 is a desktop processor from AMD, placed in the Athlon 64 (Orleans) generation and built on the K8 architecture. It uses the Orleans codename and the AMD Socket AM2 interface, with the part number ADH1620IAA5DH. No product series is listed in the FACT PACK. The processor has one core, one thread, a 2.40 GHz base clock, no boost clock, and a 45 W TDP. It was released on 2007-10-07 and its production status is end-of-life. The silicon is built on a 90 nm process with 154 million transistors and a die size of 101.3 mm². The benchmark database contains no entries for this processor: the benchmarks array is empty, the average benchmark score is 0, and the percentile versus all CPUs is 50. No nearest rivals are recorded.
Single-Thread vs Multi-Thread Behavior
With one core and one thread, the LE-1620 is a single-threaded processor. There is no second core, no second thread, and no boost clock to raise the 2.40 GHz base frequency. In practice, this means the processor can execute exactly one instruction stream at a time. The cache layout is a 64 KB L1 cache and a 1 MB L2 cache; no L3 cache and no v-cache are listed. A single-threaded workload can use that 1 MB L2 for locality, but a multi-threaded workload cannot be spread across multiple logical processors because only one logical processor exists. Even if an operating system schedules multiple tasks, they must share the same physical core.
Memory support is DDR2 in a dual-channel configuration, but no memory bandwidth figure is provided. ECC memory is not supported. PCIe Gen 2 is listed as the platform interface, but that does not add execution resources. Single-thread performance is anchored to the 2.40 GHz clock and the 64 KB / 1 MB cache hierarchy. The K8 architecture and Orleans codename are the architectural identifiers in the data. Because no boost clock is present, there is no higher transient frequency state. The processor's single-thread behavior is therefore defined by a fixed clock and a single execution core.
The benchmark data cannot quantify this behavior. The benchmarks array is empty, and the average benchmark score is 0. The percentile versus all CPUs is 50, but without a measured score, that percentile is not supported by any benchmark entry. Multi-thread behavior is similarly unmeasured. The specification makes the execution model clear: one thread, one core, no boost. The database does not provide a measured performance number to translate that model into a score.
Who Should Consider It
The market segment field is Desktop. The processor is not a server or mobile part in this data set. Its production status is end-of-life, and the release date is 2007-10-07. That means the LE-1620 is a legacy desktop processor. For a desktop workload that is strictly single-threaded, the available resources are one 2.40 GHz core, 64 KB of L1 cache, and 1 MB of L2 cache. Office workloads have no benchmark score in the FACT PACK, so no measured office performance can be stated. Gaming has no benchmark score either. The integrated graphics field is "On certain motherboards (Chipset feature)", so display output from the platform would depend on the motherboard chipset, not on the processor itself. The processor does list PCIe Gen 2, but the single-thread design still leaves only one logical processor for the rest of the system.
Creation workloads are also absent from the benchmark data. With one thread, any creation task would be limited to a single logical processor. Users who need ECC memory cannot use this processor, because ECC memory is listed as false. Users with an AMD Socket AM2 motherboard have a physical socket match. The multiplier is locked, so no frequency multiplier adjustment is available. The TDP is 45 W, the only power figure in the data. Given all of this, the potential audience is limited to single-threaded desktop tasks on an AM2 platform where multi-thread execution, ECC, and current production status are not requirements.
How It Compares
The nearestRivals array in the FACT PACK is empty. There are no nearest-rival names, no rival scores, and no deltaPct values. This means the database does not position the LE-1620 against any specific competing processor. The only relative field is percentileVsAllCpus, which is 50. That is the exact middle of the all-CPU distribution, but the average benchmark score is 0, so the percentile is not backed by measured benchmark entries. Because no deltaPct values exist, no exact percentage lead or deficit can be reported. In short, the LE-1620 has no nearest rivals in the database, and therefore no comparison paragraphs can be written.
FAQ
Q: How many cores and threads does the AMD Athlon 64 LE-1620 have?
A: It has one core and one thread, with a base clock of 2.40 GHz and no boost clock.
Q: What memory does it support?
A: It supports DDR2 memory in a dual-channel configuration. ECC memory is not supported.
Q: Does the processor have integrated graphics?
A: The FACT PACK lists integrated graphics as "On certain motherboards (Chipset feature)", so graphics output is a chipset feature on some motherboards, not a function of the processor itself.
Q: Can the multiplier be adjusted?
A: No. The multiplierUnlocked field is false, so the multiplier is locked. The base clock is 2.40 GHz.
Q: What cache does it have?
A: It has 64 KB of L1 cache and 1 MB of L2 cache. No L3 cache or v-cache is listed.
Q: Is the AMD Athlon 64 LE-1620 still in production?
A: No. The production status is end-of-life. The release date is 2007-10-07.
Benchmark Performance
The benchmark performance data for this processor is empty. The benchmarks array has no entries, and the average benchmark score is 0. There are no nearestRivals entries to provide deltaPct values, so no exact percentage difference against any rival can be calculated. This is a hard limitation of the data set: any claim such as "ahead of X" or "behind Y" would require numbers that are not present. The only numeric facts are the 2.40 GHz base clock, 64 KB L1 cache, 1 MB L2 cache, and 45 W TDP. The 90 nm process node, 154 million transistors, and 101.3 mm² die size describe the physical implementation, not the measured speed. No foundry is listed, and no memory bandwidth figure is listed.
The percentile versus all CPUs is 50, but the average benchmark score remains 0. That combination means the percentile cannot be confirmed with a measured score. The processor has one core, one thread, a locked multiplier, and no boost clock. Its memory support is DDR2 in a dual-channel configuration, and PCIe Gen 2 is the listed interface. Without benchmark scores, the only defensible benchmark conclusion is that no measured performance is recorded, and no rival comparison percentages exist.
