Phenom X4 9750 Details

Built on AMD's Agena microarchitecture at a 65 nm process node, the Phenom X4 9750 represents a mid-range desktop processor from the late 2000s, originally launched in March 2008. While outdated by modern standards, it was designed to deliver strong multi-threaded performance for its time, targeting enthusiasts and mainstream users who required a capable quad-core CPU without a discrete GPU. The chip is manufactured on a 65 nm process and integrates 450 million transistors into a 285 mm² die, operating at a base frequency of 2.4 GHz with a 12x multiplier. Despite its age, it remains a benchmark of AMD’s efforts to compete with Intel in the high-performance desktop segment during the early years of quad-core adoption.

The Phenom X4 9750 features four cores and four threads, with no support for simultaneous multithreading. It uses a dual-channel memory interface and supports DDR2 memory types, with a maximum memory capacity of 16 GB. The processor is packaged in a µPGA socket and is compatible with Socket AM2+. Its TDP of 95 W, combined with a 1.25 V maximum core voltage, indicates moderate power consumption for its era, though it requires adequate cooling due to the heat generated under load. Cache configuration includes 0.122 MiB of L1 cache, 0.488 MiB of L2 cache, and a substantial 1.907 MiB of L3 cache, which helps improve performance in memory-intensive applications.

The CPU supports a variety of instruction sets, including MMX, SSE, SSE2, SSE3, SSE4a, 3DNow!, and AMD-V virtualization technology. However, it lacks ECC memory support and has a locked multiplier, limiting overclocking potential. While the processor does not include integrated graphics, certain motherboards equipped with compatible chipsets can provide basic display output through the chipset's graphics capabilities. The Phenom X4 9750 also supports PCI-Express 2.0, enabling fast communication with peripherals and expansion cards.

In benchmark testing, the Phenom X4 9750 achieves an overall score of 4002, ranking #1885 of 2060, a single-core score of 3786 (#1900), and a multicore score of 4327 (#1663). These results place it behind slightly faster processors like the Phenom X4 9550 and Athlon II X3 400e, but ahead of lower-tier CPUs such as the A8-7410 and Celeron N4000. Its multicore performance is relatively strong compared to its single-core performance, indicating that it benefits more from multi-threaded workloads. However, its performance is dwarfed by modern processors, as seen in the top 50 lists where leading CPUs exceed 7,000 in multicore scores.

As of March 2026, the Phenom X4 9750 is no longer relevant for mainstream computing, having been superseded by more efficient and powerful processors from both AMD and Intel. It is best suited for legacy systems, retro builds, or users maintaining older hardware. While it was a capable CPU in its time, it now serves more as a historical artifact than a practical choice for modern applications.
