Core i7 4770K processor review -
Performance - Dhrystone | Whetstone
DhryStone CPU test
We make use of a multi-threaded Dhrystone test from SiSoftware Sandra, which is basically a suite of arithmetic and string manipulating programs. Since the whole program should be really small, it fits into the processor cache. It can be used to measure two aspects, both the processor's speed as well as the optimizing capabilities of the compiler. The resulting number is the number of executions of the program suite per second.
The first stop is the SANDRA DhryStone and Whetstone tests. These two tests are pure unadulterated 100% CPU tests that run completely within the CPU + cache memory itself. A perfect test to observe the general efficiency per core. Though one of the oldest, Dhrystone remains a simple yet accurate and effective way to show you RAW CPU processing performance making it a good indicator. The rest of the processors are in the chart just for scaling.
We'll show the performance results of the Core i7 4770K. You'll notice that the Z77 / Core i7 3770K is so refined and tweaked motherboard wise that it'll be faster here and there opposed to the Core i7 4770k, it's bizarre we know. We'll show some overclocked results later on in the article. Mind you that these are reference results, the Core i7 4770K on partner motherboards from MSI, ASUS and Gigabyte showed slightly faster performance at default settings.
The Whetstone benchmark is a synthetic benchmark for evaluating the performance of computers. It was initially written in Algol 60, back in 1972. The Whetstone benchmark originally measured computing power in units of kilo-Whetstone Instructions Per Second (kWIPS). This was later changed to Millions of Whetstone Instructions Per Second (MWIPS).
The Whetstone benchmark primarily measures the floating-point (FPU) arithmetic performance. A similar benchmark for integer and string operations is thus Dhrystone.
Today an article covering the Core i7 4960X (Ivy Bridge-E) on a X79 based motherboard. Intel's most high-end processors just got updated with a high-end six-core processor series aimed at consumers.
Core i7 4820K processor review
In this review we test the new four-core Core i7 4820K Ivy Bridge-E processor. This is the only quad-core IBE processor that Intel will release. But it is unlocked and as such direct competition for the Core i7 4770K.
Core i7 4770K processor review
We review the Core i7 4770K processor. The new processors family should be a notch faster, get improved graphics performance and be more energy efficient. Will the Haswell be the processor series everything you expected? Go find out in this extensive review here at Guru3D.
Core i7 3770K review with Z77
We review the Core i7 3770K Ivy bridge processors alongside Intel's Z77 motherboard. Will Ivy Bridge be the processor series everything you expected? Go find out in this extensive review here at Guru3D.
