Replacing Intel Core i5-3470 3.20GHz with Intel Core i5-3470S 2.90GHz: Is It Worth It?
When considering replacing your current Intel Core i5-3470 3.20GHz processor with the lower-power version, Intel Core i5-3470S 2.90GHz, it's important to understand the implications on performance and overall system benefit.
Understanding the Differences
Both the i5-3470 and i5-3470S processors share the same base architecture, known as the Ivy Bridge. However, there are key differences notably in the power consumption and thermal design power (TDP) of the two variants. The i5-3470, with its 65W TDP, is designed for a more conventional desktop setup, whereas the i5-3470S, with its 27W TDP, is optimized for systems that prioritize low power consumption and higher portability, such as some server or workstation configurations.
Performance Discrepancies
The notable divergence in performance between these two processors arises from the power efficiency optimization. While the i5-3470S may consume less power and potentially fit into more compact machines, it is likely to have a marginally lower single-thread performance and multi-threaded performance compared to the i5-3470. This is because the lower-power variant is designed to maximize efficiency rather than raw performance, making it a better fit for environments where power conservation is a critical factor.
According to benchmarks, the primary performance difference between the two processors is subtle enough that it might not be immediately noticeable for everyday use. However, in scenarios involving heavy computational tasks that rely on sustained high-performance, such as video editing, 3D rendering, or gaming, the i5-3470 is likely to outperform the i5-3470S.
Recommendations for Upgrading
Given the differences and considerations, upgrading from an i5-3470 to another i5-3470 processor, or even to more modern and efficient processors like the i7-3770 or i7-3770K, can offer significant benefits if you are willing to invest a little more. The i7-3770 and i7-3770K are part of the same generation and offer similar TDP, but the difference lies in the clock speed, with the i7-3770K boasting a slightly higher base and turbo frequency, making it a more robust choice for performance-sensitive tasks.
The i7-3770 comes with a TDP of 77W and offers a base clock speed of 3.4 GHz and a turbo clock speed of 3.9 GHz. The i7-3770K has the same core structure but benefits from additional features like unlocked multiplier settings, allowing for further overclocking potential. The price point for these processors is typically around $100, which is relatively affordable, making them a decent investment considering their performance advantages over the i5-3470 and the i5-3470S.
Layered Advice and Recommendations
Ultimately, the decision to upgrade from an i5-3470 to an i5-3470S or a more modern processor depends on your specific needs and usage patterns. If your system is constrained by power consumption and you are looking for a more portable solution or a quieter operation without a significant performance hit, the i5-3470S might be a suitable choice. On the other hand, if you value higher performance and are willing to spend a bit more, the i7-3770 or i7-3770K should be seriously considered for their balanced performance and efficiency.
In conclusion, while the i5-3470S is a viable option for reduced power consumption and lighter use cases, the i5-3470 and the more modern i7 series processors offer better performance and more future-proof computing needs. Consider the specific demands of your workload and the potential long-term benefits of an upgrade.
