Intel CPU performance

[NirK]

Does anyone know in % what the increases between each generation of intel CPU are at the same clocks? What is the biggest % performance increase?

For example :

Core 2 quad 3Ghz 100%
i5 1st gen 3Ghz 125%
i5 2nd gen 3Ghz
etc...

Don't know exact figures but it's pretty poor between the recent ones.

Your looking at roughly a 300mhz performance increase clock for clock over previous generation for each new CPU

 

[NirK]

I looked it up and its about 10-20% or recently more like 3-10%...

I was looking at whether I should get a Haswell now or wait for Skylake but looking at the past performance increases it will probably be 10-20% at most, so I think I will go for Haswell / Broadwell now as my current CPU is no good anymore for games. Q6700 > Haswell = 100% performance increase, Haswell > Skylake = probably 5-20% increase.

We'll have broadwell coming followed later by skylake, tbh im not expecting a big increase in performance with broadwell over current chips. Skylake may be my next move. That or wait until x99 prices settle a bit, particularly ddr4.

you might as well go for haswell now as its plenty fast, otherwise you may end up waiting years for small performance increases.

Broadwell will probably be more GPU and power saving and maybe 1-5% improvement, think I will go with a i5 haswell now and possibly upgrade to an i7 broadwell. Coming from a Q6700 that will be 2x performance. Will an i5 Haswell be over 60fps for BF4 multiplayer?

Bf4 fps will depend on the resolution and gpu/s used. But an i5 will be fine. Even with sli 780's I've seen fps drop into the 40's on a laggy server.

Here you go.

I took the single threaded Cinebench scores for a variety of gens and models and controlled for clock speed.

In the second chart the percentages are relative to the i5 760.

Efficiency improved by about 10% from gen 1 to 2, 9% from gen 2 to 3, and 13% from gen 3 to 4.

A 4th gen core does work at nearly twice the rate of the Q6600 at the same clock speed.

I suspect the i3's struggle here because of their lack of cache - gaming probably wouldn't look this severe.

 

[NirK]

Cool thanks for that, no I didn't mean that Haswell is 2x the performance at same clocks but I meant a 4690k at stock speeds is about twice the speed of a Q6700 at stock speeds.. Not sure if Passmark is the best benchmark but scores 215%....

Intel Core2 Extreme Q6800 @ 2.93GHz - 3,615

Intel Core i5-4690K @ 3.50GHz - 7,774

 

[joeyjojo]

Depends on the benchmark but that sounds about right. A 4670K scores about 260% higher in Cinebench than a C2Q at 2.5 GHz.

In terms of general overall performance the average increase based on combination of various applications, games and synthetic (least reliable) benchmarks by generation is as follows (assuming the same clockspeed and core count).


(45 nm) Penryn (tick)
(45 nm) Nehalem (tock) --> 19% IPC improvement
(32 nm) Westmere (tick) --> 2% IPC improvement
(32 nm) Sandy Bridge (tock) --> 10% IPC improvement
(22 nm) Ivy Bridge (tick) --> 6% IPC improvement
(22 nm) Haswell (tock) --> 6% IPC improvement
(14 nm) Broadwell (tick) --> ?%
(14 nm) Skylake (tock) --> ?%
( 7 nm) Cannonlake (tick) --> ?%
