Intel Core i7-3770 advantages
- The Intel i7-3770 microprocessor offers higher operating frequency than the Intel Xeon L5639 CPU.
- The microprocessor has AVX and F16C instructions, that were introduced in the recent past. While these extensions are not broadly supported by programs yet, this should improve in future apps.
- In addition to 4 CPU cores, the Intel Core i7-3770 microprocessor embeds HD 4000 graphics unit. While this GPU is not fast enough to play latest games with all settings on, it can be used for casual gaming and 3D applications.
Intel Xeon L5639 advantages
- The Xeon L5639 packs more processing cores than the Core i7-3770 processor. Large number of cores helps this CPU to handle multiple simultaneous threads or processes.
- Power consumption of the microprocessor is lower.
i7-3770 vs L5639 specifications comparison
The charts below show the difference between Intel Xeon L5639 and Intel Core i7-3770 most important characteristics. These features, along with an IPC (instructions per cycle) number, determine how well a CPU performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph corresponds to the number of additional threads, offered by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for extra frequency, provided by Turbo feature. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
