Among them, the Intel Core i7 1255U and i5 1235U stand out as two compelling options for laptops and ultrabooks. In this comprehensive comparison, we delve into the key differences between these two processors to help you make an informed decision for your next computing device.
Performance: Cores, Threads, and Clock Speeds
The Intel Core i7 1255U boasts a higher core count and thread count than the i5 1235U. It features 10 physical cores and 12 threads, while the latter has 10 cores and 8 threads. This higher core and thread count translates to improved multitasking capabilities and enhanced performance in demanding applications.
In terms of clock speeds, the i7 1255U has a base clock of 1.7 GHz and a turbo boost clock of up to 4.7 GHz. The i5 1235U, on the other hand, has a base clock of 1.3 GHz and a turbo boost clock of up to 4.4 GHz. The higher base and turbo boost clocks of the i7 1255U contribute to its superior single-core and multi-core performance.
Graphics: Intel Iris Xe Graphics
Both the i7 1255U and i5 1235U feature integrated Intel Iris Xe graphics. The i7 1255U has 80 execution units (EUs), while the i5 1235U has 96 EUs. These integrated graphics provide decent performance for everyday tasks, such as web browsing, video playback, and light gaming. However, for more demanding graphics-intensive applications, a dedicated graphics card is recommended.
Cache: L3 Cache and L2 Cache
The i7 1255U has a larger L3 cache (12MB) compared to the i5 1235U (8MB). L3 cache is a high-speed memory that stores frequently accessed data, reducing the need to retrieve data from the slower system memory. The larger L3 cache of the i7 1255U contributes to its faster performance.
In terms of L2 cache, the i7 1255U has 10MB while the i5 1235U has 8MB. L2 cache is located closer to the processor cores and is even faster than L3 cache. The larger L2 cache of the i7 1255U provides a further performance boost.
Power Consumption: TDP and Battery Life
The Intel Core i7 1255U has a higher thermal design power (TDP) of 15W compared to the i5 1235U’s 9W TDP. TDP refers to the maximum amount of heat that a processor can dissipate. The higher TDP of the i7 1255U indicates that it consumes more power and may result in shorter battery life.
Connectivity: Thunderbolt 4 and Wi-Fi 6E
Both the i7 1255U and i5 1235U support Thunderbolt 4, which offers high-speed data transfer (up to 40Gbps) and power delivery. They also support Wi-Fi 6E, the latest Wi-Fi standard that provides faster speeds and lower latency in crowded wireless environments.
Price and Availability
The Intel Core i7 1255U and i5 1235U are available in laptops and ultrabooks from various manufacturers. The price of devices equipped with these processors varies depending on the specific model, brand, and features.
Which Processor is Right for You?
The choice between the Intel Core i7 1255U and i5 1235U depends on your specific needs and budget. If you require the highest possible performance for demanding tasks such as video editing, 3D rendering, or heavy multitasking, the i7 1255U is the better choice. However, if you prioritize battery life and cost-effectiveness, the i5 1235U offers a solid balance of performance and efficiency.
