Intel Core i7-2600K and i5-2500K Processors Debut

15 thumbs up

Test System Configuration Notes: When configuring our test systems for this article, we first entered their respective system BIOSes and set each board to its "Optimized" or "High performance Defaults". We then saved the settings, re-entered the BIOS and set memory to DDR3-1333. The hard drives were then formatted, and Windows 7 Ultimate x64 was installed. When the Windows installation was complete, we updated the OS, and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled and we installed all of our benchmarking software, performed a disk clean-up, defragged the hard drives, and ran all of the tests.

Preliminary Testing with SiSoft SANDRA 2011B
Synthetic Benchmarks

We began our testing with SiSoftware's SANDRA 2011B, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2011 suite with Intel's new Core i5 and i7 "Sandy Bridge" processors (CPU Arithmetic, Multimedia, Memory Bandwidth, and Cache and Memory).  All of the scores reported below were taken with the processors running at their default clock speeds of 3.3GHz (2500K) and 3.4GHz (2600K) with 4GB of DDR3-1333 RAM running in dual-channel mode on the Asus P8P67 Deluxe motherboard.

The new Sandy Bridge-based Core i5-2500K and Core i7-2600K processors performed right about where we expected them too in the various SiSoft SANDRA tests. In the Processor Arithmetic and Multimedia benchmarks, the processors outpaced their previous-generation counterparts by a fair margin, when core counts were similar--the 6-core Core i7-980X remains Intel's fastest processor overall. The Core i5-2500K and Core i7-2600K also performed similarly in the Cache and Memory test and each one offered up about 16GB/s of peak memory bandwidth, when running in a dual-channel configuration at 1333MHz.

Amazing !! Truly amazing , the performance of the 2600k is quite Spectacular. Intel Rocks.

Awesome review, easy to understand, and well laid out...2 Thumbs up.  (brb later with some questions)

Edit: Props for the EFI Bios video demonstration on the ASUS board, that's gonna be a hot seller!!

Thanks folks. Marco did kick butt on this one and so did Intel!

An excellent look at what's new from Intel. Thanks for all of the hard work and attention to details Marco.

I blindly expect it from Marco now. Not to say that is good, or that his efforts are unappreciated, as that is not at all the case. Marco is just one of the kings of bench marking and product reviews :) Anyway; much like what I said on the mobile side of things, while very impressive I will still be looking at the next Tock before anything would be bought for me personally. I know Intel as always will amaze us on the next one to begin with, there are also things not included on this Tock that I would want. Things such as SATA and USB3 to begin with as well as there new BIOS product and there new COM specification which should be out on the next Tick I thin, and therefore optimized on the Tock as well. Technology is just moving both blindingly fast in at's capabilities today as well as in it's implementation/capabilities as well.

WOW what  great write-up ! Certainly the one we been waiting for.

I was really amazed to see what Asus did in the Bios & what kinda $$ these are going to be going for.

Thanks Marco !

dadodgeson:

has evga made a mobo yet?

Yea, the EVGA P67 Classified, but it's strange that they haven't been marketing their P67 line-up.   Asus, Gigabyte, Asrock and Intel have been working hard on promoting their Sandy Bridge motherboards, but EVGA has stayed mostly quiet . One thing I do know and see, is that EVGA's cards are everywhere, so maybe they are cooking up some hot sauce ingredients for 1155 to dazzle @ C.E.S ....
