Phenom II X4 940 Details

The Phenom II X4 940, designed by AMD, is a quad-core processor built on the K10 microarchitecture and fabricated on a 45 nm process node. Released in 2009, this CPU is now over 14 years old, placing it firmly in the category of legacy desktop processors. Despite its age, the Phenom II X4 940 remains a notable example of AMD's efforts in the mainstream desktop market during the late 2000s, offering integrated graphics and a relatively high clock speed for its time. It was positioned as a performance-oriented CPU for mid-tier systems, particularly appealing to users who required strong multi-threaded performance without the need for a discrete graphics card.

The processor operates at a base clock speed of 2.8 GHz with a maximum turbo frequency of 2.48 GHz, although this turbo value appears to be an error in the data provided, as turbo frequencies are typically higher than base frequencies. It features four cores and four threads, supporting a 5 GT/s bus speed and a 64-bit instruction set. The Phenom II X4 940 is built on the FCLGA1150 socket, allowing it to be used in motherboards that support this interface. It has a thermal design power (TDP) of 53 W, indicating moderate power consumption and heat output, which was considered efficient for a high-performance quad-core processor at its launch.

Memory support includes DDR3-1333 and DDR3L-1333 memory types, with a maximum memory capacity of 32 GB and a maximum memory bandwidth of 21.3 GB/s. The processor supports dual-channel memory configurations and PCIe 2.0 with up to 16 lanes, enabling connectivity for modern peripherals and expansion cards of its era. It also includes a range of advanced features such as SSE4.1, SSE4.2, AVX2, AES encryption, Hyper-Threading (though this is typically a feature of Intel processors), EIST, TXT, vPro, VT-x, VT-d, EPT, Secure Key, SMEP, SIPP, IPT, TSX, Flex Memory, and FMA.

The integrated graphics, labeled as HD Graphics, is a basic solution with a base frequency of 350 MHz and a burst frequency of 1050 MHz. It supports up to three display outputs and can utilize up to 1.7 GB of system memory as shared video RAM. While not powerful by modern standards, this GPU was sufficient for basic multimedia playback and light productivity tasks in its time.

In benchmark testing, the Phenom II X4 940 achieves an Overall Score of 4352, ranking #1467 out of 2060 processors, with a Singlecore Score of 4232 (#1548) and a Multicore Score of 4532 (#1175). It outperforms several contemporary processors such as the Core i5-580M and the Pentium G640T but falls behind more modern chips like the Core i3-550 and the Xeon E5472. Its performance is most competitive against other quad-core processors from the late 2000s, such as the Phenom II X4 B55 and B97.

As of March 2026, the Phenom II X4 940 is no longer relevant for modern computing tasks due to its outdated architecture, lack of support for newer instruction sets, and limited performance compared to today’s standards. It is best suited for legacy systems, retro builds, or as a budget option in older machines where power efficiency and basic computing are priorities. While it once represented a significant step forward in multi-core performance, its current role is largely historical.
