Ivy Bridge vs Sandy Bridge vs Sandy Bridge-E @ 4.7GHz Preview
Prior Reading Disclaimer / Warning:
The Ivy Bridge Core i7-3770K (recent engineering sample) results might or might not be indicative of final retail performance, and is not supported or sanctioned by Intel and their partners. As such, we will refrain from making judgements or opinions.
All test setups were equipped with 16GB of 2133MHz CL9 modules and both LGA1155 processors ran on a Z77 motherboard (brand and model not featured on our site so far).
Benchmarks (Sandra 2012 SP2)
Tests descriptions taken from http://www.sisoftware.net/?d=&f=qa&l=en
Processor Arithmetic (Dhrystone): The benchmark is designed to contain a representative sample of types of (integer) operations, mostly numerical, used by applications.
Processor Arithmetic (Whetstone): The Whetstone benchmark is widely used in the computer industry as a measure of FPU or Co-Processor performance. Floating-point arithmetic is most significant in programs that require a Co-Processor. These are mostly scientific, engineering, statistical and computer-aided design programs.
Processor Multi-Media: This benchmark generates a picture (640×480) of the well-known Mandelbrot fractal, using 255 iterations for each data pixel, in 32 colours. It is a real-life benchmark rather than a synthetic benchmark, designed to show the improvements MMX/Enhanced, 3DNow!/Enhanced, SSE(2) bring to such an algorithm.
Processor Cyptography: A set of benchmarks designed to measure cryptographic performance in the most popular algorithms today: AES for encryption/decryption (AES256/AES128) and SHA for signing (SHA256/SHA1). They allow us to show the importance of hardware accelerated support in the latest processors (CPUs) on the market today.
