Intel Haswell i7-4770K IPC and Overclocking Review

Intel's clock keeps ticking and today lands on a "tock" in the development cycle. The new desktop Haswell processor represents a new microarchitecture built on the tried and true 22nm process technology that we have come to know and love with Intel's current Ivy Bridge microarchitecture. But what does Haswell mean for the computer enthusiast?

Gaming Benchmarks

As always, these benchmarks in no way represent real-world gameplay. For this review we have added some higher resolution benchmarks at 1080P and 2560x1600 with "eye candy" turned on to better illustrate how these CPUs would compare in a real world gaming environment.

The large graphs show our traditional low resolution approach to using canned gaming benchmarks to highlight CPU differences. The smaller thumbnailed graphs again show frames per second rates while increasing the resolution and graphics quality. All of these are run with a GTX TITAN graphics card.

Yes, this original Lost Planet benchmark is very long in the tooth, but it still remains one of the few game engines that tremendously benefits from multicore processor usage.

At 640x480 and 1080P with low quality settings, we see much the same scaling. Haswell trumping Sandy Bridge-E may be a bit surprising, but clock speed still remains king in the gaming arena over threads.

This is my first outing using this benchmark for CPU comparison. The one scores that stands out is in the last three slides where Sandy Bridge scales a frame or two ahead of where we THINK it should be. Going back and checking this multiple times, the results were solidly repeatable. We are still only seeing a frame or two of advantage given to Sandy Bridge though in what is a heavily GPU-bound benchmark when scaled up in terms of resolution and quality.

BioShock Infinite returns results as would be expected.

And lastly, Metro: Last Light produces results that are a bit unexpected at lower resolutions and graphics quality, showing that this game engine is a new one that can reach into multiple threads while also leveraging the enormous amount of Sandy Bridge-E memory bandwidth. Even with that being so, again as above, a 300MHz bump in CPU clock and 133MHz in memory clock put the heavily overclocked Haswell on top every time except at higher settings where we see we are GPU limited.
