Intel Core i7-3930K And Core i7-3820: Sandy Bridge-E, Cheaper

[allthatjazz]

First iPhones, now Core i7's. Where IS this bar, anyway?

Anyone else foiled by their CAPTCHA thing? I couldn't figure out what to enter where. Feel like an idiot.

EDIT: Duh. It turns out that noscript messed it up. I temp allowed several domains, and it worked.

Dude, lengthwise cup. You must be in Bakersfield

Power??

 

[monsta]

I'm somewhat dissapointed with these new chips, I dunno maybe my expectations were too high, but for the price of the cpu and the x79 mobo, it just makes getting a 2600K more appealing to me.

 

[peevee]

[citation][nom]agnickolov[/nom]Hmm, 7% improvement over 2600K in Visual Studio isn't all that impressive... Perhaps 3930K isn't such a smart choice for a developer workstation after all.[/citation]

Looks like the project is too small and dominated by the final single-threaded link, or the build is limited by Intel 510 SSD which is slow at small accesses (and .c, .h, .obj files are slow).

It would be interesting to see the build performance on at least 5-minute Release builds on faster random-access SSDs (like Crucial m4 or Samsung 830).

If you have ideas on a larger project we can script, I'm happy to consider!

Or they simply forget to change the number of threads in Visual Studio from 8 to 12 after initial setup, and all the difference is thanks to 6 real cores serving 8 threads instead of 4.

[citation][nom]Tomfreak[/nom]Intel should have sell the 2011 CPU as 8 core instead of disable the 2 cores and sell at six core. 2011 cpu may be an enthusiast CPU, but it is still a high volume CPU compared to server cpu, it cant be the yield in Intel fab are so bad that all 2011 CPU produce by Intel have only 6 working cores at best.[/citation]

They do sell 8-core SBEs, only call them Xeons and sell for much higher even compared to the insanely priced 3960X.

And I bet those 2 or 4 disabled cores in most SBEs are PERFECTLY GOOD, at least on stock speeds. It is called marketing, market segmentation. Wonton destruction of value. My engineering heart weeps.

Only, they don't sell them yet. Early next year. And you're right, the disabled cores probably work fine. Don't feel *too* bad, though. Disabled cores also don't consume power. Turned on, these things wouldn't run at the same clocks (or at least they'd dissipate more heat). So the trade off is fewer cores and more frequency, which is probably more useful to more desktop users anyway.

Chromium.

And don't forget to change the number of Visual Studio threads if you put the drive to the other system!

Your argument USED to be valid before Turbo and other power technologies. Now, unused cores don't consume (and dissipate) much, and Windows 7 can even park them completely.

Appreciate it Peevee. Will dig into this some more and hopefully come up with something more demanding!

Its a shame some of those X79 boards are so nice when the processors don't make a great case for the platform switch. Guess it'll come down to the combos available when I'm ready to buy.

 

[buzznut]

These new CPUs are great, no doubt about it. I wouldn't pay that, at least I couldn't if I wanted to.

One thing I noticed about the benchmark charts, Zambezi doesn't seem so overpriced now. Of course if they really wanted to move those things, AMD ought to sell them for around $200.

I agree, I can see no reason to spend $1000 for a CPU these days. Nice to see Intel addressing different market segments.

OK lets get this straight only 6 cores while the Xeon e7 8870 has 10 and has been around for a while now.

You mean the $4600 processor intended for eight-way servers? Have fun with that ;-)

Does anyone even play WOW anymore? If you want to test a CPU for gaming, use Supreme Commander 2.

Actually I can gets these very cheap except one needs a minimum of 4 of them to run for a few hundred bucks used but the boards are very rare and expensive. Try the average price $2-2.5k a pop for each board. They are also rather large but 8 of these in a maxed out server can very easily cost as much as $230,000! Most only run cheap old dual socket 771 or opteron servers but for raw power few can afford a beast like that. 160 total threads, 256gb of ram, 240mb total in just L3 cache.

Actually there are still people who do and not just the retail tards who are willing to fork over for the fees but there are plenty of us who play on private servers that never got ruined by cata.

So here I sit with my i7-920 wondering ... is it worth it to think to upgrade or wait for another year?

 

[Guest]

10 years ago this type of raw compute power was for supercomputers, and small render farms easily costing tens of thousands and much much more.
Now imagine 10, no wait - 5 years from now: It's going to be amazing! Spesh t3h m0b1l3 s3ct0r

So completely off subject, which by the way another great review and explanation of another great Intel product, but after you enter the contest, it says that the contest runs from December 8, 2011 9PM PST and closes January 2012 9pm PST. So what's the day in Jan that it ends? >.

and again... canadians excluded... yaaaaaaay

i mean.. come ON.. I get that it's not worldwide, but excluding them canucks is just lame

Whoever designed the captcha at the end of the competition entry form should be shot. It says "enter text exactly as displayed" when what it means is "enter the sum of the two numbers"

yes.. i, too, had a problem with the "captcha"..the same issue.. i finally tried entering the sum of the two numbers and that worked..
