AMD Phenom X4 9750 (125W)

The AMD Phenom X4 9750 (125W) is a desktop processor built on the K10 architecture with the Agena codename, featuring four cores and four threads at a base clock of 2.40 GHz with no boost clock. It carries a 125W thermal design power, uses the AMD Socket AM2+ interface, and is fabricated on a 65 nm process node with 450 million transistors on a 285 mm² die. The cache hierarchy comprises 128 KB of L1 per core, 512 KB of L2 per core, and 2 MB of shared L3, while the memory bus is dual-channel and ECC memory is not supported. The part number is HD9750XAJ4BGH, it was released on 2008-03-26, and its production status is end-of-life. The database places this processor at the 50th percentile among all tracked CPUs, with an average benchmark score of zero and no nearest rivals listed.

How It Compares

The data for the Phenom X4 9750 (125W) includes no nearestRivals entries, which means no direct competitor comparisons with percentage deltas can be drawn from the record. The only positional metric available is the percentile vs all CPUs, which is 50. This places the processor exactly at the median of the database's tracked population — a point where half of all CPUs in the dataset score higher and half score lower. In practical terms, the 50th percentile indicates a mid-pack standing, neither a top-tier performer nor a bottom-tier part, but the absence of rival scores prevents any specific statements about which CPUs it sits beside or by how much it leads or trails them.

Without nearestRivals data, the benchmark analysis cannot reference specific competitor names, score differences, or percentage gaps. The percentile value of 50 is the sole comparative anchor. It suggests that in aggregate performance terms, this processor represents the midpoint of the distribution — a useful baseline for understanding its relative position, but not a substitute for head-to-head deltas. The average benchmark score of zero further confirms that no measured performance results are attached to this entry, so any ranking derived from the percentile must be treated as a positional placeholder rather than a quantified performance verdict.

Because the nearestRivals array is empty, the "How It Compares" section is necessarily limited to the percentile observation. The 50th percentile is a neutral, central value; it does not indicate a strong or weak standing, merely a median one. For a four-core, four-thread part with a 2.40 GHz base clock and no boost capability, this central ranking is consistent with a processor designed for mainstream desktop workloads rather than extreme performance. However, without rival data, no further refinement of that positioning is possible from the facts provided.

Power and Thermals

The thermal design power of the Phenom X4 9750 (125W) is explicitly stated as 125W. This is a fixed thermal envelope that the cooling solution must be able to dissipate under sustained load. A 125W TDP class implies the need for a capable air cooler — not a small low-profile unit, but a substantial heatsink-and-fan assembly that can handle the heat output. The "125W" designation in the product name itself signals this thermal requirement, distinguishing it from lower-TDP variants in the same family.

The process node is 65 nm, and the die size is 285 mm² with a transistor count of 450 million. These figures are recorded in the database, and while they do not directly quantify thermal density, they provide context for the 125W envelope: a larger die area and a mature 65 nm process typically distribute heat across a wider surface, which can ease the burden on a given cooler compared to a smaller, more concentrated die. The base clock of 2.40 GHz is the only operating frequency listed, as there is no boost clock, meaning the processor runs at a constant frequency and its thermal output is tied to that fixed rate.

The absence of a boost clock simplifies thermal management — the CPU does not dynamically raise its frequency, so the peak thermal load is bounded by the 2.40 GHz base clock rather than a transient boost state. This makes the 125W TDP a reliable estimate of worst-case heat generation. The integrated graphics are listed as "On certain motherboards (Chipset feature)", which means the graphics functionality is not on the CPU die itself but provided via the motherboard chipset; this has no direct bearing on the CPU's own thermal design. For a system builder, the 125W envelope dictates a cooler with sufficient heat dissipation capacity, and the fixed clock rate ensures that the cooling requirement does not fluctuate with workload-driven frequency changes.

Benchmark Performance

The benchmark section of the FACT PACK shows an average benchmark score of zero and an empty benchmarks array. This means no individual benchmark results are recorded for the Phenom X4 9750 (125W) in this database. Consequently, there are no exact scores to analyze, no percentage deltas to compute against rivals, and no performance curves to interpret. The only performance-related data point is the percentile vs all CPUs, which is 50.

The 50th percentile is a meaningful metric even without raw scores. It indicates that, in the database's historical tracking, this processor performs at the median level — that is, it is faster than roughly half of all CPUs ever tracked and slower than the other half. This is a broad, aggregate statement, not a precise benchmark result, but it does place the processor in a defined performance tier. For a four-core part with no boost clock, a median standing is a plausible outcome, but the data does not allow any finer-grained analysis such as "30% ahead of X in multi-core" because no such rival data exists.

The lack of benchmark scores also means that the processor's real-world performance in specific workloads — single-threaded, multi-threaded, memory-bound, or otherwise — cannot be characterized from this record. The dual-channel memory bus and the 2 MB shared L3 cache are architectural facts that influence performance, but without measured results, they remain structural details rather than performance evidence. The percentile value of 50 is the only quantitative performance indicator, and it must serve as the sole basis for any performance-related conclusion: this CPU sits at the midpoint of the tracked population.

Platform and Compatibility

The Phenom X4 9750 (125W) uses the AMD Socket AM2+ interface, which is the physical and electrical connection to the motherboard. The memory bus is dual-channel, and the database records no specific memory support details beyond that, so the type and speed of memory are not specified in the data. ECC memory is not supported, meaning error-correcting memory modules cannot be used with this processor. The PCIe interface is listed as "Gen 2", indicating second-generation PCI Express connectivity for expansion cards and other peripherals.

The processor is based on the K10 architecture with the Agena codename, and it belongs to the Phenom X4 generation. The integrated graphics are described as "On certain motherboards (Chipset feature)", which means that display output is not provided by the CPU itself but by a chipset on select motherboards; this is a platform-level feature rather than a CPU-integrated GPU. The multiplier is not unlocked, so the clock multiplier is fixed and cannot be adjusted for overclocking through the multiplier alone.

The production status is end-of-life, meaning the processor is no longer in active production, and the release date is 2008-03-26. The market segment is desktop, confirming its intended use in desktop systems. The process node is 65 nm, and the transistor count is 450 million on a 285 mm² die. The part number is HD9750XAJ4BGH. The upgrade path is constrained by the AM2+ socket: any motherboard that supports this processor must have an AM2+ socket, and the end-of-life status means no new boards are being produced for it. The dual-channel memory bus and PCIe Gen 2 support are the key platform features that determine what kind of system this CPU can be installed into — a desktop board with AM2+, dual-channel memory slots, and PCIe Gen 2 expansion slots.
