Intel Core i7-3970X Sandy Bridge-E CPU Review

13 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 mid to high bit-rate and VBR (variable bit rate) MP3 audio encoder that is used widely around the world in a multitude of third party applications.

LAME MT
Audio Conversion and Encoding

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

Our custom LAME MT benchmark doesn't scale past two cores, so the Core i7-3970X's additional resources aren't put to use. With that said, the chip still put up the best score of the bunch, which matched the Ivy Bridge-based Core i7-3770K.
 
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 testing using the latest version of Internet Explorer 9, with default browser settings, on a clean install of Windows 7 Ultimate x64.

The Ivy Bridge-based Core i7-3770K put up the best score in the SunSpider benchmark, but the Core i7-3970X finished right behind it and outpaced the rest of the pack easily. The AMD FX processors finished well behind the Intel chips here.

Nice to hear but this one might be super expensive that ordinary people cant afford to buy :(

the 3960X is $1049.99 on newegg... this is the 3970x...you sir, are correct.

And what happened to Ivy Bridge-E?

Ivy Bridge-E hasn't been released yet... ;-)

Looks to be a pretty incredible processor. Like the others have pointed out, well beyond what I could even begin to afford for a PC.

If you have actual use for this chip, it is a monster and worth every penny from a productivity perspective IMO. Def. not cheap, thats why we have the 3930K otherwise :)

Great Reviews on new Intel I7 3970X. I like this. Very impressed that it can run at 4.80 GHz. plenty power for this i7 3970X.

I would prefer my 3770k price for performance. The 3970 and x79 platform is more for bragging rights then anything else.

When are the pecs for the haswell proccessors going to be released? i want to buy a 3970x when they do. I've been saving up and can't wait.

I though it would smoke FX-8350 by a very large margin. But surprisingly, only about 60% faster. I'm quite impressed with AMD , albeit much higher power consumption, but hey, its 4 times cheaper.
