CPU Comparison

Intel Core i7-3517UE vs Intel Core i7-3555LE

A side-by-side comparison of specs, performance and value. The Intel Core i7-3517UE is a specialized ultra-low voltage mobile processor launched in June 2012 as part of the Ivy Bridge family. The 'UE' suffix denotes its focus on embedded and ultra-thin systems, operating at a 17-watt TDP. Built on Intel's 22nm process, it features 2 cores and 4 threads. The processor runs at a base clock of 1.7 GHz and can boost up to 2.8 GHz. It includes 4MB of L3 cache and supports dual-channel DDR3 memory. A standout feature of the 3517UE is its support for ECC (Error-Correcting Code) memory, making it suitable for small-scale servers, industrial PCs, and critical embedded systems where data integrity is paramount. While its dual-core design limits multi-threaded performance, its combination of low power consumption, ECC support, and Intel HD Graphics 4000 makes it a versatile chip for specialized industrial applications rather than consumer laptops.

Our Verdict on Each

A reliable 2012 embedded chip with ECC support, but too slow for modern consumer workloads.

Best for: If you are considering the Intel Core i7-3517UE, you are likely maintaining an older industrial PC or a specialized embedded system. This processor should not be sought for consumer use, as its dual-core design is severely outdated for modern multitasking and productivity workloads. It is only recommended if you need to keep a specific legacy system running that requires a direct replacement part with ECC memory support. Avoid using this CPU for general web browsing or modern office work, as its performance is too low and inefficient. It is best utilized in its original context: low-power, always-on embedded systems where stability is paramount. For any new industrial builds, modern embedded processors offer vastly superior performance, security, and power efficiency.
