The Sandy Bridge Review: Intel Core i7-2600K, i5-2500K and Core i3-2100 Tested

You guys asked for it and finally I have something I feel is a good software build test. Using Visual Studio 2008 I'm compiling Chromium. It's a pretty huge project that takes over forty minutes to compile from the command line on the Core i3 2100. But the results are repeatable and the compile process will stress all 12 threads at 100% for almost the entire time on a 980X so it works for me.
I don't have a full set of results here but I'm building up the database. The 2600K manages a 12% lead over the previous generation high end chips, but it can't touch the 980X. The 2500K does well but it is limited by its lack of Hyper Threading. The Phenom II X6 1100T beats it.

Do you happen to remember the space heater.....ahem, I mean P4?DanNeely - Monday, January 3, 2011 - link
I do. Intel used bigger heatsinks than they do for mainstream parts today.panx3dx - Monday, January 3, 2011 - link
The article states that in order for quick sync to function, a display must be connected to the integrated graphics. Since p67 does not support the IGP, then quick sync will be disabled???panx3dx - Monday, January 3, 2011 - link
Opps, just saw Doormat already asked the question on page three, and I can't find a way to edit or delete my post. However no one has yet to give a clear answer.Next9 - Monday, January 3, 2011 - link
There is not any problem with BIOS and 3TB drives. Using GPT you can boot such a drive either on BIOS or UEFI based system. You should only blame Windows and their obsolete MS-DOS partitioning scheme and MS-DOS bootloader.mino - Monday, January 3, 2011 - link
Microsoft not supporting GPT on BIOS systems (hence 3TB drivers on BIOS systems) was a pure BUSINESS decision.It had nothing to do with technology which is readily available.

In the table there is "N" for the i3 CPUs.But in the text there is: "While _all_ SNB parts support VT-x, only three support VT-d"
Could you check it out and clarify? (there is no data on ark.intel.com yet)

It's not exactly true that HD3000 has less compute performance than HD5450, at least it's not that clear cut.It has 12 EUs, and since they are 128bit wide, this would amount to "48SP" if you count like AMD. Factor in the clock difference and that's actually more cores (when running at 1300Mhz at least). Though if you only look at MAD throughput, then it is indeed less (as intel igp still can't quite do MAD, though it can do MAC).
It's a bit disappointing though to see mostly HD2000 on the desktop, with the exception of a few select parts, which is not really that much faster compared to Ironlake IGP (which isn't surprising - after all Ironlake had twice the EUs albeit at a lower clock, so the architectural improvements are still quite obvious).

That's not true. Each AMD SP is a pipeline, the 4th one on a 69xx (or 5th on a 58xx) series card is 64 bits wide, not 32. They can't all be combined into a single 128 (160, 196) bit wide FPU.kallogan - Monday, January 3, 2011 - link
I'll wait for 22 nm. No point in upgrading for now
