Competitors of Ryzen 5 PRO 3400GE from Intel

We believe that the nearest equivalent to Ryzen 5 PRO 3400GE from Intel is Core i5-9500T, which is nearly equal in speed and lower by 2 positions in our rating.

Here are some closest Intel rivals to Ryzen 5 PRO 3400GE:

Advantages of Intel Core i7-3970X

Cheaper ($495 vs $700)

Higher base clock speed (3500 vs 3300 MHz)

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

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)


Thermal Monitoring Technologies


Advantages of AMD Ryzen 5 PRO 3400GE

0.4% better performance in benchmarks

Much newer (30 September 2019 vs 1 November 2012)

Finer manufacturing process technology (12 vs 32 nm)

Lower power consumption (35W vs 150W), meaning that the rival with higher TDP might require a better cooler or other thermal solution.

AVX2 (Advanced Vector Extensions 2 - an extension to AVX, the set of SIMD instructions working with 128- and 256-bit registers)

AES (Advanced Encryption Standard instructions set - hardware acceleration of AES encryption and decryption. Speeds up encryption software, e.g. Veracrypt)

x86-64 (a general name for 64-bit extension of x86 instruction set. There are AMD64 and Intel 64 versions that differ very little)

Virtualization (Hardware acceleration of virtual machines)
