Page 1: Test: Intel Core i7-4820K
In early September Intel released the new Ivy Bridge-E CPUs for its new current X79 high-end platform: Intel Core i7-4960X, Core i7-4930K and Core i7-4820K. So far, however, we were only able to test the top model with six cores. This time, we have a look at the smallest "Ivy Bridge-E" CPU, priced at 310 dollars, which is just below the fastest "Haswell" CPUs. We will see whether grabbing one of the more expensive CPUs is worth it compared to the Intel Core i7-4770K.
Intel's Core i7-4960X is without question the fastest CPU for now. But not everyone needs a six-core CPU for everyday tasks. Not every game is optimized for more than four cores, which our benchmarks have clearly shown. Compared to the Intel Core i7-4770K or the Intel Core i7-3770K, this six-core was able to put up only a tiny advantage in gaming benchmarks. Nevertheless, the X79 platform has a clear added value for gamers: it provides much more lanes for multi-GPU operation of more than two graphics cards, and is ablle to access installed 3D accelerators with full speed, which ultimately results in higher frame rates. Before we test the platform on their multi-GPU performance, we first take a closer look at the Intel Core i7-4820K, the smallest "Ivy Bridge-E" CPU, a quad-core CPU.
Compared to the current "Haswell" flagship, it not only provides a slightly faster base clock but also a larger amount of cache memory, and implements fast DDR3 memory. Let's see whether the Intel Core i7-4820K can keep up with current "Haswell" CPUs and how this top model performs compared to to its large six-core brothers.
