Athlon II P340 Details

Ranked #1841 of 2060 in overall performance, the Athlon II P340 sits near the lower end of the CPU hierarchy as of March 2026, offering modest capabilities suited for basic computing tasks. While it shares a similar overall score with higher-end processors like the A4-7210 and A4-3320M, its performance lags significantly behind modern mainstream and high-end CPUs, which dominate the top 50 lists. The processor's single-core performance, at a score of 3938, places it just behind the Athlon II X2 235e and Core 2 Duo T5870, indicating it holds its own in lightly threaded applications but lacks the power for modern multitasking or demanding workloads.

The Athlon II P340 is built on a 14 nm process node and features a 64-bit architecture with four cores and four threads, operating at a base frequency of 1.44 GHz and a turbo frequency of up to 2.3 GHz. It supports LPDDR3 1600 memory with a maximum capacity of 8 GB and a memory bandwidth of 25.6 GB/s, running on a 5 GT/s bus speed. With a TDP of 17 W, the chip is energy-efficient, making it suitable for compact or low-power systems. It is designed for the UTFCBGA1380 socket, indicating its use in mobile or embedded platforms.

Despite its age, the processor supports a range of modern instruction sets, including SSE4.1, SSE4.2, AVX2, AES, and x86-64, which provide compatibility with current software. It also supports Hyper-Threading, allowing it to handle multiple threads simultaneously, and includes features like EIST, TXT, and VT-x for power management and virtualization. However, it lacks ECC memory support, limiting its use in enterprise environments.

The integrated HD Graphics 400 GPU, clocked at 200 MHz with a burst frequency of 600 MHz, supports up to three displays and is capable of handling basic multimedia and light gaming. While not powerful by today’s standards, it offers sufficient graphics performance for office applications, video playback, and casual use.

In conclusion, the Athlon II P340 is a legacy processor designed for entry-level systems and low-power devices. Its performance is best suited for basic computing, web browsing, and light productivity tasks. As of March 2026, it is no longer competitive with modern CPUs but remains a viable option in budget or legacy systems where power efficiency and cost are prioritized over performance.
