Compatibility

Information on Core i9-9980XE and Core i9-9940X 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 i9-9940X from AMD

We believe that the nearest equivalent to Core i9-9940X from AMD is Ryzen 7 5800X, which is nearly equal in speed and higher by 1 position in our rating.

Here are some closest AMD rivals to Core i9-9940X:

Advantages of Intel Core i9-9980XE

2.7% higher performance in benchmarks

Higher boost clock speed (4500 vs 3300 MHz)

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)

vPro (a marketing umbrella term for several Intel technologies: AMT, TXT, EDB, VT, Anti-Theft and some others)

Advantages of Intel Core i9-9940X

Cheaper ($1067 vs $1665)

So, which one is the better CPU?

Technical City couldn't decide between Intel Core i9-9980XE and Intel Core i9-9940X. The differences in performance seem too small.
