Intel Core i7-860 vs Intel Core i5-650

The Intel Core i7-860 and the Intel Core i5-650 are desktop processors that target different user needs.

The Intel Core i7-860 is based on the Lynnfield architecture and is intended for users who require high computing power. In contrast, the Intel Core i5-650 uses the Clarkdale architecture and targets the broad market for standard PCs. The Intel Core i7-860 is manufactured using a 45 nm process with four cores and eight threads, while the Intel Core i5-650 uses a 32 nm process but offers only two cores and four threads.

Both processors support PCIe 2.0 and have a memory bandwidth of 17 GB/s as well as 1 MB Level 2 cache. In benchmarks, the Intel Core i7-860 delivers significantly superior single-core and multi-core performance. The performance difference compared to the Intel Core i5-650 is significant and well above the ten percent mark.

In games, the Intel Core i7-860 offers more stable frame rates thanks to its 8 MB Level 3 cache and higher thread count. The Intel Core i5-650 only has 4 MB Level 3 cache and reaches its limits faster in many gaming scenarios. The thermal design power of the Intel Core i7-860 is higher, requiring better cooling.

The Intel Core i5-650, on the other hand, scores with an integrated Intel HD Graphics unit and higher energy efficiency. Since both models are only available used, the price-performance ratio varies depending on the offer. The Intel Core i7-860 is the right choice for computationally intensive applications, while the Intel Core i5-650 is suitable for simple office systems without a dedicated graphics card.
