Intel Core i7-3770K Ivy Bridge Processor Review

23 thumbs up

In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a popular scenario that many end users work with on a day-to-day basis to provide portability and storage of their digital audio content. LAME is an open-source MP3 audio encoder that is used widely in a multitude of third party applications.

LAME MT
Audio Encoding

In this test, we created our own 223MB WAV file (a hallucinogenically-induced Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application, in both single and multi-thread modes. Processing times are recorded below, listed in seconds. Shorter times equate to better performance.

Our custom LAME MT benchmark uses only one or two threads. As a result, the Core i7-3770K's ability to Turbo to higher frequencies than the other processors, in addition to the slight IPC enhancements of the architecture, allow it to outpace all of our reference systems.

SunSpider JavaScript Benchmark
JavsScript Performance Testing

Next up, we have some numbers from the SunSpoder JavaScript benchmark. According to the SunSpider website:

This benchmark tests the core JavaScript language only, not the DOM or other browser APIs. It is designed to compare different versions of the same browser, and different browsers to each other. Unlike many widely available JavaScript benchmarks, this test is:

Real World - This test mostly avoids microbenchmarks, and tries to focus on the kinds of actual problems developers solve with JavaScript today, and the problems they may want to tackle in the future as the language gets faster. This includes tests to generate a tagcloud from JSON input, a 3D raytracer, cryptography tests, code decompression, and many more examples. There are a few microbenchmarkish things, but they mostly represent real performance problems that developers have encountered.

Balanced - This test is balanced between different areas of the language and different types of code. It's not all math, all string processing, or all timing simple loops. In addition to having tests in many categories, the individual tests were balanced to take similar amounts of time on currently shipping versions of popular browsers.

Statistically Sound - One of the challenges of benchmarking is knowing how much noise you have in your measurements. This benchmark runs each test multiple times and determines an error range (technically, a 95% confidence interval). In addition, in comparison mode it tells you if you have enough data to determine if the difference is statistically significant.

All of the systems were tested using the latest version of Internet Explorer 9, with default browser settings, on a clean install of Windows 7 Ultimate x64.

The new Core i7-3770K also put up the best scores we have seen in the SunSpider JavaScript benchmark. Whether using a discrete GPU or the integrated Intel HD 4000 series graphics, the Core i7-3770K offered better overall performance than the rest of the systems.

Nice review on new Intel Ivy Bridge that moved to 22 nm and look faster and less than 80 watts of power. I am very impressed with the reviews. Now I'm wonder will Intel make Ivy Bridge Extreme Edition on new 22 nm? We will find out about it later.

You can bet EE version CPUs are waiting in the wings my friend. :)

Intel is keeping the pressure on. This looks like a worthy CPU to have.

Amazing Intel!!! :D, although i won't be upgrading to this i will be getting the mobile version :). Going to head on over to read that now xD.

Great review Marco! I'm really liking the performance to power ratio! Intel keeps bringing the heat!

Not much of a move if you're already on Sandy, but now's the chance for you guys who are still on C2Qs and the like. The graphics have improved, but they won't be touching Trinity with that kind of performance.

Nice review.

Ivy Bridge is an awesome processor but not worth the upgrade at this point if you already have Sandy Bridge or Sandy Bridge-E. Now if you are upgrading from anything previous it's a no brainer.

Some beautiful architecture especially with the 3D modelling/layout internally

Thank you Marco for the review, when did this come out, or when is it?
