Is Haswell clock for clock faster than Ivy?

[Tola]

is 4.5Ghz on ivy equivalent to 4.5Ghz on a Haswell based system?

[coen113]

almost, like 10 percent difference max

[Cacao]

Haswell is about ~5-10% faster, nothing noticeable in normal usage.

[Guest Gazzer96]

I would suspect that the newer system will perform better, it would run hotter, though.

[tedjani]

yeah not that much not going to rock your pc

[The_Strict_Nein]

Yes, around 10%

[LawrenceBarnes2013]

it is higher clocked by 5~10% but it's the technology within that new architecture that will make the improvement  ,not totally up to the clock speeds

[That Norwegian Guy]

The IPC (instructions per clock) difference between Haswell and Ivy Bridge is exactly 7.4003%. (Aggregate average difference between same-clock 3570K vs. 4670K Passmark results)

 

Ivy Bridge on average overclocks 10~15% further.

 

If you intend to overclock, get Ivy. Final performance will be higher.

I don't know many who live and die by the extra two native SATA ports nor the meek power savings of on-die VRM controller. In fact the only recorded effect I've seen it have on people I know is an increased risk (for normal consumers) of buying a power supply that won't work.

There's up to 20% more IPC: http://www.pcgameshardware.de/screenshots/original/2013/09/SC2HotS-pcgh.png

And one more showing a 20% difference: http://images.hardwarecanucks.com/image//skymtl/CPU/INTEL-HASWELL/INTEL-HASWELL-45.jpg

If we just focus purely at cinebench, it's pretty much 4.2GH HW = 4.5GHz IB = 4.8GHz SB and magically thats the average overclock for each generation - but why should we look at cinebench if we have tests in games thats more relevant to the majority thats atleast giving you somewhat an idea of real world usage? Kinda same thing as the 2500K having only a 50% improvement in IPC to a 8350 but we're seeing even up to 100% difference in games. Doing some maths with the benchmarks above, that would mean a 4.3GHz HW is equal to a 4.9GHz IB.

 

 

5-10%, max.
