Compatibility

Information on Xeon E3-1275 v5 and Core i7-6700 compatibility with other computer components: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.

Competitors of Core i7-6700 from AMD

We believe that the nearest equivalent to Core i7-6700 from AMD is Ryzen 5 2400GE, which is nearly equal in speed and higher by 4 positions in our rating.

Here are some closest AMD rivals to Core i7-6700:

Advantages of Intel Xeon E3-1275 v5

4.1% higher performance in benchmarks

More powerful video core

Somewhat newer (19 October 2015 vs 1 July 2015)

ECCMemory

Advantages of Intel Core i7-6700

Cheaper ($323 vs $444)

Higher boost clock speed (4000 vs 3600 MHz)

Lower power consumption (65W vs 80W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.

HyperThreading (allows one physical CPU function as two logical ones. It increases performance, since while one logical CPU is waiting for data, the second may still do useful work)

AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)

TSX-NI (Transactional Synchronization Extensions New Instructions - hardware acceleration of multithreaded calculations for Intel CPUs)

Quick Sync (hardware acceleration of video encoding and decoding for Intel CPUs. Speeds up video encoding by times, but at the cost of somewhat lower quality)

Virtualization (Hardware acceleration of virtual machines)
