Gaming performance

Let's see how good Core i5-9300H and Core i5-8257U are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i5-9300H

MMX (MultiMedia Extensions - the very first (1996) SIMD instruction expansion for Intel desktop CPUs, works with 64-bit registers)
SSE (Streaming SIMD Instructions - a SIMD instruction extension working with 128-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)

Advantages of Intel Core i5-8257U

1.5% faster in synthetic tests
Somewhat newer (10 July 2019 vs 30 April 2019)
Less power hungry (15 vs 45 watts)
