[Tom's Hardware] Core i7-4770K: Haswell's Performance, Previewed - Page 11

post #101 of 571
It appears to be a carbon copy increase of what it was from Sandy to Ivy Bridge. I don't see the problem? Along with other under the hood changes, it's a decent upgrade.

If you already have IVY, you have NO reason to upgrade. But i'd say it's a big enough leap from Sandybridge if you're getting that impulsive need to upgrade something

However now we're in a strange spot where most intel enthusiasts are on 1155, a mainstream socket where the priority has always been mainstream stuff such as TDP and IGP performance. The fact is that intel is still releasing expensive platforms and expensive chips with little to no regard for TDP or graphics. Just see X79, SB-E, and upcoming stuff such as IB-E and haswell-E where the rumored TDP has been brought up to 160W at stock settings. The problem of course is that these things are expensive, just like they were when 1366 came out.

The source of that "problem" as I see it is that Z77 + 3570K or 3770K is more than sufficient for even a large majority of enthusiasts.

There's relatively little to be gained by going with X79 unless you're using 3-4 video cards and/or a hex-core chip like the i7-3930K.

what is really interesting is that the K parts and some others will have TSX disabled. Is anyone bright enough to guess why? Just seems rather retarded to me..thinking.gif

'

The problem is that it's the same performance increase but with the need to upgrade to a whole new platform to use it. This means spending 500 bucks or more if you want to get an i7. That's not great price/performance. However, we don't know anything yet until we know how well these overclock. I mean, after all, who's going to run them stock?

More like 33% (4.0->5.0) for the 8350 and 50% for the 920 (2,66-> 4.0). The 5.0 Ghz and 4.0Ghz respectively are pretty common max clocks for both CPUs respectively. Anything more and its up to luck.

In that case you can always just drop an ivy cpu in the place of the sandy one, without the need to change the mobo. You can get half the upgrade with minimal cost.

wasn't that expected? a 10% CPU performance and around 30% graphics enhancement?

I believe Now i'm set on the 3770K until the second gen Haswell in 2015

It's just sad you have to upgrade mb for such a small step. If I wanted to change from Ivy to haswell it would be close to 300$ for 10% more performance.
