AMD Athlon X4 750

The AMD Athlon X4 750 is a desktop processor built on the Piledriver architecture with the Richland codename. It ships with four cores and four threads, a base clock of 3.40 GHz and a boost clock of 4.00 GHz, and is manufactured on a 32 nm process at GlobalFoundries. The part is end-of-life and sits at the 50th percentile in the database's ranking of all CPUs.

Single-Thread vs Multi-Thread Behavior

The Athlon X4 750 presents a straightforward execution profile: four cores with four threads, meaning the thread count matches the core count exactly, with no additional logical processors. This is a classic setup for workloads that scale across four independent execution units, but it also means that heavily threaded software that expects more logical processors will see only four. The base clock of 3.40 GHz rises to a boost clock of 4.00 GHz, giving the chip meaningful frequency headroom for lightly threaded tasks. When few cores are active, the boost clock can sustain higher instruction throughput, which benefits single-threaded applications such as older games or lightly threaded productivity tools.

The cache hierarchy reinforces this split. The processor carries 192 KB of L1 cache and a 4 MB L2 cache, with no L3 cache present. In single-threaded workloads, the L1 and L2 latencies dominate, and the absence of an L3 means that the L2 is the final shared cache before main memory. For multi-threaded workloads, the four cores share the 4 MB L2, so contention on the shared cache can become a factor when all four threads are active. The data suggests that the processor is best suited to workloads that either use few threads heavily, or that distribute work across four threads without requiring a large shared pool of cached data.

The boost behavior is worth emphasizing: the 4.00 GHz boost clock is only reached when thermal and power headroom allow, and with a 65 W TDP, the chip has a modest power envelope to work within. In practice, sustained all-core loads may hold clocks closer to the base 3.40 GHz, while single-threaded bursts can reach the 4.00 GHz ceiling. This means the single-thread performance is relatively strong for the architecture, while multi-thread performance is limited by the four-thread ceiling and the shared cache arrangement.

Power and Thermals

The Athlon X4 750 is rated at a 65 W TDP, placing it in a moderate power class for a desktop processor. This is a four-core part on a 32 nm process from GlobalFoundries, with 1,303 million transistors on a 246 mm² die. The combination of a 65 W thermal envelope and a 32 nm process node means the chip does not require an exotic cooling solution; a capable air cooler with a standard 65 W-class heatpipe design is sufficient to maintain operation within its thermal limits.

The die size of 246 mm² is relatively large for a 65 W part, which means the heat density is moderate. The 1,303 million transistor count indicates a fairly dense design for the era, but the 32 nm process spreads that heat over a large area, keeping temperatures manageable under load. Because the multiplier is unlocked, users can raise clocks beyond the 4.00 GHz boost, but doing so increases power draw above the 65 W TDP, so the thermal solution must be matched to the overclocked state. At stock settings, the 65 W TDP is a conservative figure that implies a straightforward cooling tier — a standard tower cooler or a low-profile cooler with adequate airflow.

The end-of-life production status means that thermal guidance is fixed; there are no new steppings or revised power profiles expected. For system builders, the 65 W rating is the key planning number: it allows the use of compact power supplies and modest cooling, but it also means that sustained all-core loads will be governed by the thermal limits of the chosen cooler.

Platform and Compatibility

The Athlon X4 750 uses the AMD Socket FM2 interface, which ties it to a specific motherboard generation. The platform supports DDR3 memory in a dual-channel configuration, with a memory bandwidth of 29.9 GB/s. This bandwidth figure is a fixed characteristic of the memory controller, and it is sufficient for the four-core design, though it does limit how quickly data can be fed to the cores compared to higher-bandwidth platforms.

PCIe support is Gen 2, which is an older generation of the interconnect standard. This affects the bandwidth available to discrete graphics cards and NVMe storage adapters. For a processor of this class, PCIe Gen 2 is adequate for the typical graphics cards of its era, but it is a limiting factor when paired with modern high-bandwidth devices. The platform does not support ECC memory, so error-correcting memory is not an option.

The multiplier is unlocked, which is a notable feature for the platform. This allows the user to adjust the clock multiplier in the motherboard BIOS to increase or decrease the operating frequency of the cores. The part number AD750XOKA44HL identifies the specific SKU. The socket FM2 platform has a defined upgrade path within the same socket generation, but with the processor being end-of-life, the practical upgrade options are limited to other FM2 parts that are also no longer in production.

There is no integrated graphics on this processor, so a discrete GPU is mandatory for any display output. This is a consideration for system builders: the platform must include a graphics card, which adds cost and power draw to the overall system. The absence of an iGPU also means that the processor cannot be used for light display tasks without a dedicated graphics solution.

How It Compares

The database places the Athlon X4 750 at the 50th percentile among all CPUs, meaning it sits exactly at the midpoint of the performance distribution. This is a useful anchor for positioning: the processor is faster than the lower portion of the distribution and slower than the upper portion. However, the nearestRivals data for this processor is not populated in the database, so there are no direct rival comparisons with specific score deltas available.

The 50th percentile ranking reflects the processor's balanced but unremarkable performance profile. It is not a high-end part, nor is it at the bottom of the distribution. The four-core, four-thread configuration with a 4.00 GHz boost clock places it in the middle tier of desktop processors from its generation. Compared to processors with more cores or higher clock speeds, the Athlon X4 750 will trail in multi-threaded workloads; compared to lower-clocked or dual-core parts, it will lead in both single-threaded and multi-threaded tasks.

The lack of rival data means that any comparison must be drawn from the percentile figure alone. At the 50th percentile, the processor is a reasonable baseline: it outperforms the lower portion of the CPU landscape, but it does not challenge the upper portion. For workloads that are single-threaded, the 4.00 GHz boost clock is competitive; for multi-threaded workloads, the four-thread limit caps its potential.

Benchmark Performance

The benchmark dataset for the Athlon X4 750 is empty, with an average benchmark score of zero. This is an important caveat: the percentile ranking of 50 is derived from the database's overall distribution, but there are no individual benchmark runs recorded for this specific processor. This means the 50th percentile should be interpreted as a placement based on the processor's characteristics and the database's classification, rather than from direct measured scores.

In the absence of benchmark scores, the performance analysis must rely on the architectural specifications. The base clock of 3.40 GHz and boost clock of 4.00 GHz are the primary determinants of single-threaded performance. The four cores and four threads define the multi-threaded ceiling. The 4 MB L2 cache and 192 KB L1 cache determine cache sensitivity. The 29.9 GB/s memory bandwidth sets the data feeding rate.

When placed against the 50th percentile anchor, these specifications suggest a processor that will deliver competent performance in everyday desktop tasks, moderate performance in lightly threaded applications, and limited performance in heavily threaded workloads that exceed four threads. The absence of an L3 cache means that workloads with large working sets that exceed the 4 MB L2 will incur memory latency penalties, which can reduce effective performance in database-style or large-file workloads.

The empty benchmark array also means that there are no exact percentage deltas to report against rivals. Any comparative statements must be qualitative, grounded in the percentile placement and the architectural characteristics. The 50th percentile is the most informative metric available: it places the processor in the middle of the field, neither a standout nor a laggard.

Who Should Consider It

The Athlon X4 750 is suited to workloads that align with its four-core, four-thread design and its 4.00 GHz boost clock. For gaming, the processor can handle titles that are optimized for four threads and that rely on high clock speeds rather than many cores. Games that are heavily single-threaded will benefit from the boost clock, while games that scale beyond four threads will leave the processor behind.

For content creation, the picture is mixed. Light photo editing and audio processing that use few threads will run reasonably well. Video encoding and 3D rendering that scale across many threads will be limited by the four-thread ceiling. The 29.9 GB/s memory bandwidth and the 4 MB L2 cache are adequate for moderate-sized datasets, but large project files will cause cache misses and memory stalls.

For office and productivity use, the Athlon X4 750 is a competent performer. Spreadsheets, word processing, web browsing, and email are all lightly threaded and will run at or near the 4.00 GHz boost clock. The 65 W TDP makes it easy to cool in a compact desktop or an office tower, and the unlocked multiplier provides headroom for users who want to extract additional performance.

The end-of-life status means that this is not a processor for new high-end builds. It is best suited to a straightforward desktop where the four cores are sufficient, where a discrete GPU is already planned, and where the 50th percentile performance level is acceptable. Users with workloads that demand more than four threads, or that require high memory bandwidth, should look elsewhere in the database.

The absence of an integrated GPU is the most significant practical limitation. Any system built around this processor must include a discrete graphics card, which increases the overall system cost and power draw. For users who already have a GPU, the Athlon X4 750 offers a straightforward four-core platform with a 4.00 GHz boost clock and an unlocked multiplier.
