AMD Ryzen 5 240 VS AMD Ryzen AI 5 340

At a foundational level, the AMD Ryzen 5 240 and the AMD Ryzen AI 5 340 share a surprising amount of common ground: both are built on a 4 nm process node, support the same PCIe 4.0 interface, include integrated graphics, and are rated for an identical 100 °C maximum operating temperature. Both also target the same markets, being certified for use in laptop and desktop configurations with full 64-bit support. This means neither processor holds an architectural or platform compatibility advantage over the other in these respects.

The single most meaningful differentiator in this group is Thermal Design Power (TDP). The Ryzen 5 240 carries a 45W TDP, while the Ryzen AI 5 340 is rated at just 28W — a reduction of roughly 38%. In practical terms, a lower TDP means the 340 generates less heat under sustained load, demands less from the cooling system, and draws significantly less power from the battery. For laptop implementations in particular, this translates directly into longer battery life, thinner and quieter chassis designs, and better thermal sustainability during extended workloads.

Based strictly on the general specs provided, the Ryzen AI 5 340 holds a clear efficiency advantage. Achieving the same platform compatibility, the same process node, and the same feature set at a meaningfully lower thermal envelope is a net positive in almost every deployment scenario — especially mobile use cases where power and heat management are critical constraints.

The AMD Ryzen 5 240 and AMD Ryzen AI 5 340 both feature 12 threads, providing solid multitasking capabilities. However, their CPU speeds differ: the Ryzen 5 240 has a higher base speed of 6 x 4.3 GHz, while the Ryzen AI 5 340 operates with a lower base speed of 3 x 2 GHz and 3 x 2 GHz, totaling 6 GHz.

For turbo performance, the Ryzen 5 240 boosts up to 5 GHz, while the Ryzen AI 5 340 reaches a slightly lower turbo clock speed of 4.8 GHz. Both processors have a locked multiplier, meaning their clock speeds cannot be overclocked.

Both processors have the same L2 and L3 cache sizes—6 MB and 16 MB, respectively. However, the Ryzen AI 5 340 utilizes big.LITTLE technology, which is not present in the Ryzen 5 240. The Ryzen 5 240 uses a clock multiplier of 43, while the Ryzen AI 5 340 uses a clock multiplier of 20.

When comparing the benchmark results for the AMD Ryzen 5 240 and AMD Ryzen AI 5 340, the Ryzen 5 240 outperforms the Ryzen AI 5 340 in the overall PassMark result, scoring 22,576 compared to the Ryzen AI 5 340's 20,210. In terms of single-threaded performance, the Ryzen AI 5 340 has a slight advantage, with a score of 3,882 versus the Ryzen 5 240's 3,533.

Looking at Geekbench 6 results, the Ryzen AI 5 340 again leads in multi-threaded performance, achieving 8,951, while the Ryzen 5 240 scored 7,816. For single-threaded performance in Geekbench 6, the Ryzen 5 240 scores higher with 2,382, compared to the Ryzen AI 5 340's 2,280.

Overall, the Ryzen 5 240 has a higher overall PassMark score and a better single-threaded Geekbench 6 score, while the Ryzen AI 5 340 excels in multi-threaded performance on both PassMark and Geekbench 6 benchmarks.

The AMD Ryzen 5 240 and AMD Ryzen AI 5 340 both feature integrated graphics, but they differ in GPU specifications. The Ryzen 5 240 is equipped with the Radeon 760M, which has a turbo clock speed of 2,600 MHz. In contrast, the Ryzen AI 5 340 uses the more powerful Radeon 840M, with a higher turbo clock speed of 2,900 MHz.

Both processors support DirectX 12, but the Ryzen AI 5 340 goes a step further by supporting DirectX 12 Ultimate, which includes advanced features such as ray tracing and variable rate shading, offering a more future-proof experience compared to the Ryzen 5 240's DirectX 12.

Both products support up to 4 displays, offering similar multi-display capabilities.

The AMD Ryzen 5 240 and AMD Ryzen AI 5 340 both support DDR5 memory and utilize 2 memory channels, offering similar memory architecture. The maximum RAM speed for the Ryzen 5 240 is 7,500 MHz, while the Ryzen AI 5 340 supports a slightly higher maximum RAM speed of 8,000 MHz.

Both processors can handle up to 256 GB of memory, and neither supports ECC (Error-Correcting Code) memory, meaning they are both geared more toward general use rather than error-sensitive applications.

Overall, the two processors share many similarities in their memory capabilities, with the Ryzen AI 5 340 having a slight edge in RAM speed.

Both the AMD Ryzen 5 240 and AMD Ryzen AI 5 340 share the same instruction sets, including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, which ensure compatibility with a wide range of applications and workloads. This means they are both capable of handling modern computing tasks efficiently with these advanced instruction sets.

Both processors also support multithreading, enabling better performance in multi-tasking and parallel workloads. Additionally, both processors have the NX bit, a security feature that helps prevent the execution of malicious code in certain areas of memory, enhancing system security.

In summary, the two processors are identical in terms of supported instruction sets, multithreading, and security features, with no notable differences in this group.
