[Tom's Hardware] - i7-3930K & i7-3820

post #1 of 12
Thread Starter 
For those interested in how the i7-3820 compares to its big brothers...

Quote:
We got our hands on the Core i7-3930K and Core i7-3820 to gauge their overclocked performance and determine if they’re able to best the flagship part.

Really hate how TH does reviews.

I'm proud of them for crowning the 3930K instead of the 3960X... 3820 seems like a funny processor to put into the X79 platform, but none the less... a mediocre article from Tom's. Didn't really state anything we didn't know.

It's not beyond few extra ratios.

X79 allows to use a multiplier for QPI (1.25x, 1.5x, 1.75x etc), which still runs at 100 MHz . That was you can increase the CPU clock while leaving all the system clock at stock.

I think the article just served more to show off the merits & value of the 3930k which I have to admit is a pretty darn amazing cpu for the price.

Though... I guess someone who might oddly want to jump on lga2011, but does not quite have the budget yet for the 3930k, or someone who wants the memory bandwidth of the X79 platform, but does not want nor need the extra cores (yeah I know that's really stretching what someone could want out of SB-E); it could be a valid choice.

I mean at least it would give them an upgrade path for later. (either more cores, or IB-E next year)

But as we all know the 2700k/2600k/2500k etc etc are much more economical offering similar performance.

Their scores for averaging seem to be quite poor.

Not too bad, but SB-E is supposed to be Extreme. I really wish SB-E had 8-core processors and this was a 6-core processor. Since this is an enthusiast platform if you're already spending this much you may as well go for the 6-core processors. Otherwise it would be better to get a Core i5-2500k now and upgrade to Ivy Bridge early next year.

Given the extra cache as well, plus decent OCability even without multiplier OCing.
