AMD Ryzen 7 260 VS AMD Ryzen 9 8940HX

Both the AMD Ryzen 7 260 and the Ryzen 9 8940HX share several foundational characteristics: they are each compatible with both laptop and desktop platforms, include integrated graphics, support 64-bit computing, and top out at a 100 °C maximum CPU temperature. These shared traits mean neither has a fundamental architectural or platform advantage in terms of deployment flexibility or basic feature set.

Where the two diverge meaningfully is in thermal envelope and manufacturing process. The Ryzen 7 260 is built on a 4 nm process node versus the 8940HX's 5 nm, which generally translates to better power efficiency and more transistor density for the 260 — an advantage in thermally constrained systems. The 8940HX, however, carries a higher 55W TDP compared to the 260's 45W, meaning it is designed to sustain greater sustained power draw and, by extension, can support heavier workloads over time — at the cost of more heat and battery consumption. Additionally, the 8940HX steps up to PCIe 5.0 versus the 260's PCIe 4.0, offering up to twice the bandwidth for compatible NVMe storage or discrete GPUs.

Based strictly on these general specs, the picture is mixed. The Ryzen 7 260 holds the edge in manufacturing efficiency (4 nm vs. 5 nm), making it the better choice for power-sensitive or compact builds. The Ryzen 9 8940HX counters with a higher thermal ceiling and PCIe 5.0 support, giving it the advantage in high-performance configurations where bandwidth and sustained throughput matter more than efficiency.

The AMD Ryzen 7 260 features a CPU speed of 8 x 3.8 GHz with a turbo clock speed of 5.1 GHz, while the AMD Ryzen 9 8940HX has a lower base CPU speed of 16 x 2.4 GHz but a slightly higher turbo clock speed of 5.3 GHz. This suggests that while the Ryzen 7 260 has a higher base clock speed, the Ryzen 9 8940HX might be more efficient with its multi-core performance due to its higher thread count and lower base frequency.

In terms of CPU threads, the Ryzen 7 260 supports 16 threads, whereas the Ryzen 9 8940HX offers double that with 32 threads, allowing for potentially better multitasking and parallel processing capabilities. Both processors use the same L2 cache configuration, with 1 MB per core, but the Ryzen 9 8940HX has a significantly larger L2 cache overall (16 MB compared to the Ryzen 7 260's 8 MB).

The Ryzen 9 8940HX also has a much larger L3 cache (64 MB compared to the Ryzen 7 260's 16 MB), which may lead to faster access times for frequently used data. Both processors use a clock multiplier—38 for the Ryzen 7 260 and 24 for the Ryzen 9 8940HX—but the Ryzen 9 is the only one with an unlocked multiplier, allowing for more flexible overclocking potential. Neither processor uses big.LITTLE technology.

In terms of overall performance, the AMD Ryzen 7 260 achieves a PassMark result of 29,915, while the AMD Ryzen 9 8940HX significantly outperforms it with a result of 51,227. This shows a notable difference in overall multi-core processing capability between the two processors.

For single-core performance, the Ryzen 7 260 scores 3,826, which is very close to the Ryzen 9 8940HX's single-core score of 3,860. Although the Ryzen 9 has a slightly higher single-core result, the gap is relatively small, indicating that both processors perform similarly in tasks that rely on a single core.

Overall, the Ryzen 9 8940HX excels in multi-core performance, but both processors show similar single-core performance levels.

The AMD Ryzen 7 260 features the Radeon 780M integrated GPU with a GPU clock speed of 800 MHz and a turbo speed of 2700 MHz. In contrast, the AMD Ryzen 9 8940HX comes with the Radeon 610M GPU, which has a lower base GPU clock speed of 400 MHz and a turbo speed of 2200 MHz. This indicates that the Ryzen 7 260 offers a higher GPU clock speed and better turbo performance.

Both processors support DirectX 12, OpenGL 4.6, and OpenCL 2.1, ensuring compatibility with modern graphics APIs. They also support up to four displays. However, the Ryzen 7 260 has a considerably more powerful GPU in terms of architecture, with 48 texture mapping units (TMUs), 32 render output units (ROPs), and 768 shading units. On the other hand, the Ryzen 9 8940HX has just 8 TMUs, 4 ROPs, and 128 shading units.

Overall, the Ryzen 7 260 has a more capable integrated GPU, offering higher clock speeds and a significantly larger number of GPU units compared to the Ryzen 9 8940HX's more modest integrated graphics capabilities.

The AMD Ryzen 7 260 supports a maximum RAM speed of 7500 MHz, while the AMD Ryzen 9 8940HX supports a lower maximum RAM speed of 5200 MHz. Both processors use DDR5 memory and feature two memory channels, ensuring efficient data transfer between the CPU and RAM.

In terms of maximum memory capacity, the Ryzen 7 260 supports up to 256GB of RAM, whereas the Ryzen 9 8940HX is limited to 64GB of RAM. Both processors do not support ECC (Error-Correcting Code) memory, which is typically used for more critical workloads where memory errors need to be minimized.

Overall, the Ryzen 7 260 offers higher RAM speed and a much larger memory capacity than the Ryzen 9 8940HX.

Both the AMD Ryzen 7 260 and the AMD Ryzen 9 8940HX support the same set of instruction sets, including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2. These instruction sets provide enhanced processing capabilities for a variety of applications, including multimedia, cryptography, and parallel computing tasks.

Both processors also support multithreading, enabling them to handle multiple threads simultaneously, which can improve performance in multitasking and parallel workloads. Additionally, both CPUs have the NX bit, which provides security benefits by preventing certain types of malicious attacks that attempt to execute code in non-executable memory areas.

In summary, the Ryzen 7 260 and the Ryzen 9 8940HX are identical in terms of instruction set support, multithreading capabilities, and the inclusion of the NX bit, with no differences in these key features.
