Information on Xeon E5-2450 and Xeon E5-2623 v3 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.

Gaming performance

Let's see how good Xeon E5-2450 and Xeon E5-2623 v3 are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately. Also, your gaming PC must have a decent enough GPU to perform well.

Both CPUs satisfy the 100% minimum and 97% recommended requirements of all games known to us.


Advantages of Intel Xeon E5-2450

Cheaper ($209 vs $278)

Lower power consumption (95W vs 105W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.

AVX (Advanced Vector Extensions - a set of SIMD instructions working with 128- and 256-bit registers)

Intel 64 (64-bit Intel CPU architecture. Almost identical to AMD64, except small and rarely used nuances)

TXT (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)

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)

Advantages of Intel Xeon E5-2623 v3

0.8% better performance in benchmarks

Much newer (1 July 2014 vs 14 May 2012)

Finer manufacturing process technology (22 vs 32 nm)

So, which one is the better CPU?

Technical City couldn't decide between Intel Xeon E5-2450 and Intel Xeon E5-2623 v3. The differences in performance seem too small.
