AMD Athlon II X4 620e

The AMD Athlon II X4 620e is an end-of-life desktop processor from AMD. The fact-sheet entry records the architecture as K10, the codename as Propus, and the generation as Athlon II X4 (Propus). The part has four cores, four threads, and a base clock of 2.60 GHz; no boost clock appears in the data. It uses AMD Socket AM3, supports DDR3 memory over a dual-channel bus, and is listed with PCIe Gen 2. The TDP is 45, and the part sits at the 50th percentile versus all CPUs in the database.

Benchmark Performance

The benchmarks array in the fact pack is empty. The average benchmark score is listed as 0, and the nearestRivals array is also empty, so there are no rival scores or deltaPct values to analyze. Any statement claiming a percentage lead or deficit over another CPU would have no numeric basis in this data. The only performance-ranking field present is percentileVsAllCpus, and its value is 50. That places the Athlon II X4 620e at the median of the database’s CPU distribution: half of the recorded processors sit above it, half below it.

Because measured scores are absent, the raw specification fields become the primary quantitative record. The processor offers four cores and four threads, which defines the amount of parallel execution width available. The base clock is 2.60 GHz, and no boost clock is recorded, so the database contains only one frequency value for this chip. The cache layout is documented as 128 KB of L1 cache per core and 512 KB of L2 cache per core, with no L3 field value and no 3D V-Cache field value. These details do not by themselves create a benchmark score, but they describe the hardware that any future benchmark run would measure.

The 50th percentile has to be read carefully in this context: it is a positional rank, not a score. It does not tell which workloads favor this processor or how far it is from neighboring parts. It simply states that the database places this CPU at the exact middle of all CPUs. The empty benchmark and rival lists mean that no exact deltas can be reported, no percentile spread can be computed, and no rival-specific conclusion can be drawn from measured results.

Platform and Compatibility

The socket field is AMD Socket AM3. The memory support field is DDR3, and the memory bus is dual-channel. The fact pack does not include a memory bandwidth number, so the only documented memory characteristics are the DDR3 type and the dual-channel bus width. ECC memory support is listed as false, meaning the data does not credit this processor with error-correcting memory capability.

The PCIe field is Gen 2. Integrated graphics is not listed as an on-die CPU feature; the fact pack describes it as “On certain motherboards (Chipset feature)”. That wording implies that display output would depend on the motherboard’s chipset rather than on the processor itself. The multiplierUnlocked field is false, so the clock multiplier is not documented as unlocked.

The market segment is Desktop. The release date is 2011-05-02. The production status is End-of-life. The part number is recorded as AD620EHDK42GMAD620EHDGMBOX. The series field is null, while the generation field is Athlon II X4 (Propus).

The upgrade path, based strictly on what is in the pack, is limited to the AM3 socket. No other AM3 processors are listed in this entry, and no successor in a higher series is named. A builder evaluating this platform can see that the memory type is DDR3, the bus is dual-channel, PCIe is Gen 2, and ECC is unsupported. Those facts describe the platform boundaries more precisely than any score would.

How It Compares

The nearestRivals array is empty. There are no rival product names, no rival scores, and no deltaPct values in the fact pack. This section therefore cannot provide one paragraph per nearest rival, because no nearest rivals are recorded.

The only comparative positional fact is percentileVsAllCpus: 50. Against the full database, the Athlon II X4 620e is at the midpoint. It is not positioned near the top of the distribution, nor is it near the bottom; it sits in the middle. Without named rivals, it is impossible to say whether it leads one chip in multi-threaded work or trails another in single-threaded work. The data simply does not include those comparison points.

Given this absence, the comparison story is structural rather than measured. Four cores and four threads put it in the same execution-thread class as other four-thread desktop processors, but no rival entries confirm what those parts are. The per-core L1 and L2 sizes, the lack of L3, and the 2.60 GHz clock are the traits that would influence any future benchmark comparison, but they cannot be converted into percentages until rival scores are added.

A: The release date is 2011-05-02, and the production status is end-of-life.

Who Should Consider It

Workloads that can divide into four parallel threads align naturally with this processor. It has four cores and exactly four threads, so software that uses four threads can occupy every hardware thread. Workloads that require more than four threads will not find additional threads in the data, because the thread count equals the core count.

For frequency-sensitive work, the recorded base clock of 2.60 GHz and the absence of a boost clock are the relevant constraints. Applications that depend heavily on one or two fast cores may be limited by that single frequency value. For more parallel desktop workloads, the four-core design offers more simultaneous execution resources than a dual-core part would, though no dual-core rival is named in the pack to confirm a comparison.

The platform fields indicate a desktop-oriented AM3 build with DDR3 memory and PCIe Gen 2. The lack of ECC support means memory-error-correcting workstation scenarios fall outside the documented feature set. The chipset-dependent graphics situation means a motherboard with the appropriate chipset feature would be required for any display output; the CPU itself is not recorded as containing graphics logic.

Because there are no benchmark scores, workload recommendations cannot be validated against measured software performance. The recommendation is therefore based on the structural facts: four cores, four threads, 2.60 GHz base clock, no boost clock, DDR3 dual-channel memory, AM3 socket, and no ECC. A user with software that fits four threads and a platform that fits AM3/DDR3 is the audience this data describes.

Single-Thread vs Multi-Thread Behavior

The fact pack does not contain separate single-thread and multi-thread benchmark scores. The only positional rank, the 50th percentile, is a whole-CPU measure. Still, the specification fields imply a split in behavior. The thread count equals the core count: four cores and four threads. That means the data describes a processor where each core can handle one hardware thread, with no SMT-style thread multiplication documented.

The cache structure is entirely per-core in this entry: 128 KB L1 per core and 512 KB L2 per core, with no L3 value. For code that fits into per-core cache, each core has its own local storage. For data that must be shared across cores, no shared L3 is listed to serve as a common pool. The lack of L3 does not produce a benchmark number, but it is part of the architectural picture.

The clock behavior also matters for the single-thread versus multi-thread split. Only a 2.60 GHz base clock is recorded, and no boost clock is present. Single-threaded performance therefore rests on what one core can do at that clock with its private L1 and L2. Multi-threaded performance rests on how well software uses all four cores simultaneously. The database does not quantify how those two modes compare for this chip, because the benchmarks array is empty.

Power and Thermals

The TDP is recorded as 45. That is the only power figure in the fact pack. It indicates a modest thermal envelope for a desktop processor, especially in the context of the 45 nm process node, the 169 mm² die size, and the 300 million transistor count. Those physical and thermal fields together suggest a cooling requirement that is not in the high end of the desktop spectrum.

The 45 nm process node is listed, while the foundry is null. The transistor count of 300 million and the die size of 169 mm² accompany the TDP figure. No wattage figures for other CPUs are included in the pack, so no relative thermal comparison can be made. The data does not provide a cooler size, a cooler tier, or any thermal solution specification.

The absence of a recorded boost clock also means the fact pack contains no higher-frequency operating state that would add another power data point. With only the base clock and a 45 TDP, the thermal characterization is simple: a low-power desktop part, based on the one numeric value provided.
