AMD Athlon X2 7550

The AMD Athlon X2 7550 is a desktop processor from the 7000 series, built on the K10 architecture under the Kuma codename. It pairs 2 cores and 2 threads at a 2.50 GHz base clock with no boost capability, on the AMD Socket AM2+ platform. Launched on December 14, 2008, on a 65 nm process with 450 million transistors on a 285 mm² die, this end-of-life part occupies the 50th percentile of all CPUs in the benchmark database, with an average benchmark score of 0 reflecting the absence of recorded performance runs. The part number AD7550WCJ2BGH identifies the specific SKU.

Benchmark Performance

The Athlon X2 7550 holds a 50th percentile ranking among all CPUs tracked in the database. That places it at the exact median of the field — half of all recorded processors perform above it, half below. Its average benchmark score is 0, and the benchmark array is empty, meaning no runs have been logged for this part. The percentile is therefore a positional placeholder rather than a measured performance result. The empty benchmark array distinguishes this part from processors with logged runs; its 50th percentile is derived from its position in the overall distribution rather than from direct measurement.

The hardware basis for its expected performance is a dual-core, dual-thread design at 2.50 GHz. With no boost clock, the processor runs at a fixed frequency under all conditions. The K10 architecture and the 2 MB shared L3 cache provide the memory hierarchy, with 128 KB of L1 and 512 KB of L2 per core. The 65 nm process node with 450 million transistors on a 285 mm² die defines the physical implementation. This combination of a fixed 2.50 GHz clock and a dual-core layout means the processor's performance ceiling is also its sustained performance level — there is no turbo headroom to exploit.

Because the nearest-rival list is empty, there are no deltaPct values to report. The 50th percentile is the only comparative anchor available. In absolute terms, a 2-core/2-thread part at 2.50 GHz from the K10 generation represents the entry-level dual-core tier of its era. The fixed clock means predictable behavior across all workloads, with performance scaling linearly up to two threads and then flatlining.

Who Should Consider It

The Athlon X2 7550 is a 2-core, 2-thread desktop processor. Workloads that use one or two threads at a time will see the full benefit of the 2.50 GHz base clock. Office productivity — document editing, spreadsheets, email, and web browsing — fits squarely within this dual-thread envelope. The dual-channel DDR2 memory interface with 17.1 GB/s of bandwidth supplies data to the two cores without a narrow single-channel bottleneck. Memory support is DDR2 and depends on the motherboard, so the platform's memory speed is tied to the specific board and modules chosen.

For gaming, the picture is more limited. The processor has 2 cores and 2 threads, and no boost clock, so frame rates in titles that expect more than two threads will be constrained by the fixed 2.50 GHz frequency. The 2 MB shared L3 cache helps with data reuse, but the dual-thread ceiling is the binding constraint. Games contemporary with its December 14, 2008 release are a better match, as are indie and esports titles that scale to two threads.

For content creation, the 2 MB shared L3 cache and 128 KB L1 / 512 KB L2 per core give the processor enough on-die storage for small working sets. However, rendering and video encoding workloads that scale beyond two threads will not benefit — the processor offers exactly 2 threads, with threads equal to cores, meaning no simultaneous multithreading. The locked multiplier means no overclocking headroom; the 2.50 GHz base clock is the maximum frequency the part will ever deliver. System builders targeting light creation tasks on a Socket AM2+ platform will find the 95W TDP easy to cool, but heavy parallel workloads will not see gains from this processor's dual-thread design.

Single-Thread vs Multi-Thread Behavior

With 2 cores and 2 threads, the Athlon X2 7550 executes exactly one thread per core. There is no boost clock, so single-thread performance is a direct function of the K10 architecture's instructions-per-clock at a fixed 2.50 GHz. The 128 KB L1 and 512 KB L2 per core give each thread a dedicated cache path, while the 2 MB shared L3 allows both threads to share frequently accessed data without going to system memory. This cache arrangement is particularly beneficial for workloads where two threads operate on overlapping data sets, as the shared L3 acts as a fast intermediary between the cores and the DDR2 memory bus.

Multi-thread performance scales across the two cores, but stops there. Any workload with more than two runnable threads will time-slice on the same two cores, and the absence of SMT means no additional logical threads to absorb the overflow. The dual-channel DDR2 memory bus at 17.1 GB/s provides the external bandwidth; the shared L3 reduces pressure on that bus for data shared between the two threads. The result is a processor that handles dual-thread workloads with full efficiency but degrades gracefully — not sharply — when thread counts exceed the hardware's capacity.

The 50th percentile ranking reflects this balanced-but-modest profile. A processor that sits at the median of all CPUs — even without logged benchmark runs — is one that neither excels nor falters in the general-purpose desktop space. The fixed 2.50 GHz clock means predictable, consistent performance: no turbo spikes, no throttling from boost behavior, just a steady frequency that makes performance easy to anticipate.

How It Compares

The nearest-rival list for the Athlon X2 7550 is empty. No competitor names, scores, or deltaPct values are recorded in the database. The only comparative metric is the 50th percentile against all CPUs, which places it at the median of the entire tracked field. This absence of rival data means the processor cannot be positioned against specific alternatives in this database, and no percentage deltas can be computed.

Its platform context is defined by Socket AM2+ and the K10 architecture. The 7000 series and the Kuma codename situate it within AMD's dual-core desktop lineup of its generation. The 95W TDP and 65 nm process place it in the same power/performance class as other mid-range dual-core parts of the 2008 era, but without logged rival scores, any further comparison would be speculative. The production status is end-of-life, meaning the part is no longer manufactured, and its market segment is desktop, indicating its intended use in full-size systems rather than mobile or embedded designs.

Power and Thermals

The Athlon X2 7550 has a 95W TDP. On a 65 nm process with 450 million transistors across a 285 mm² die, that TDP reflects the power draw of a dual-core K10 design at a fixed 2.50 GHz. A 95W thermal envelope is a moderate requirement; a capable air cooler is sufficient to keep the processor within its thermal limits. The lack of a boost clock means power draw is steady under load, with no transient spikes from frequency ramping, which simplifies cooling design.

The processor does not include integrated graphics; the chipset on certain motherboards provides display output. This shifts graphics power to the motherboard chipset rather than the CPU. The 95W TDP therefore covers only the CPU cores and cache. Memory support is DDR2, dependent on the motherboard, with a dual-channel interface delivering 17.1 GB/s. ECC memory is not supported, which keeps the memory controller simpler and reduces platform power overhead.

The 95W TDP combined with the 65 nm process suggests a cooling tier that is modest by modern standards but appropriate for the era. A stock-style air cooler would handle the thermal load, and the fixed 2.50 GHz clock ensures no boost-driven thermal peaks. For system builders, the Socket AM2+ platform and DDR2 memory requirement define the surrounding hardware. The 450 million transistors on a 285 mm² die indicate a dense-for-its-time layout, but the 65 nm node's power characteristics are what set the 95W TDP. With ECC disabled and no integrated graphics on the CPU, the power budget is entirely devoted to the two K10 cores and the shared 2 MB L3 cache.
