Gaming performance

Let's see how good Core i7-3840QM and Core i5-8250U are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i7-3840QM

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)

Advantages of Intel Core i5-8250U

0.3% faster in synthetic tests
Much newer (21 August 2017 vs 3 September 2012)
Cheaper ($297 vs $568)
Finer manufacturing process technology (14 vs 22 nm)
Less power hungry (15 vs 45 watts)
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)
