32nm vs 22nm Performance differences

[RBOShadow]

Hello! How big is the performance difference between 32nm and 22nm processors? I refer to a AMD FX-8350 with 32nm vs an Intel i5/i7/xeon processor. I want to know how big are the differences at the processor performance?

Die size affects heat output, power draw and production costs mainly rather than performance.

Performance is mainly affected by how good the architecture is.

Good architectures will give good performance and vice versa.

 

[jaguarskx]

Yep. Die shrinks do not mean an automatic increase in performance since it basically just means the size of the transistor has been reduced.

Intel CPUs generally improve in performance with die shrinks because they also modify the CPU architecture a little bit. For example, Broadwell is the die shrink of Haswell. Other than reduced power consumption and heat emissions, they also plan on improving the iGPU. Early estimates ranges between 30% - 40% improvement over Haswell iGPU. They have not made any bold statements about improved CPU performance so it's safe to assume that it will probably be another 6% average improvement.

So, what do you recomend? an AMD FX 8350 or an intel i5?

 

[jay_nar2012]

Depends on what you will be doing.

 

[RBOShadow]

I will be doing video editing, gaming and programming so i need a powerfull processor with a good capacity of multitasking.

 

[jay_nar2012]

Well the FX 8320/8350 would be better at multi-tasking than the i5 so i would recommend the fx 8320 and OC it.

 

[RBOShadow]

If I OC it ican get better singlethreaded performance? The singlethreaded performance differences are noticeable between theese processors?

 

[jay_nar2012]

Well the i5 will have much better single threaded performance compared to the FX but yes, OC can improve single threaded performance on the FX.

main diffrences between die shrink is heat and power comsumption which means really better performance per watt

e.g lets take 2 similar processors from amd and intel

http://cpuboss.com/cpus/Intel-Core-i5-3330-vs-AMD-FX-6300

now lets take i5 3570k vs 8350

http://cpuboss.com/cpus/Intel-Core-i5-3570K-vs-AMD-FX-8350

while you could get similar peformance from amd fx line the 8 cores draw alot more due to there die size.

these are both fairly decent comparisons and show strenghts and weaknesses another weakness of amd processors is that they are hindered by windows 7 and would be best paired with windows 8

keep in mind occing will draw more power and reduce your processors life

 

[RBOShadow]

It is noticeable this ST performance difference?

It is noticeable this ST performance difference?

depends os your using windows 8 hardly but if you pitted them of on 7 yes its noticeable

depends on processor of choice reason windows 7 hates fx is due to it is very thick and isnt optmised for modules.

 

[jay_nar2012]

Well in single threaded apps, the ST difference would be noticeable by up to a few mins depending on what the app is.

What are games? Singlethreaded tasks or multithreaded tasks?

 

[jay_nar2012]

Most games these days are mostly multithreaded, some old games maybe single threaded.

 

[beyondlogic]

What are games? Singlethreaded tasks or multithreaded tasks?

depends on your game

games these days use multithreading for audio visual etc though 2 to 4 cores at most in some games but games now are pushing 6 core these being the extreme bf4 for example.

starting up programs will be slower though by a few mins

overall performance and efficiency the i5 wins.

 

[RBOShadow]

In percentage, what is the difference at ST tasks between FX 8350 and an i5/i7?

 

[master x]

i5 and i7 are good at single threaded apps and so normal tasks are handled easily by them but gaming and other heavy intense prgs need multiple core and while i7 has hyperthreading i would suggest going for an amd fx 8 core which is cheaper more powerful and future proof than an i7 do use win 8 or linux and dump win7

 

[rgd1101]

amd fx 8 core which is cheaper more powerful and future proof than an i7 do use win 8 or linux and dump win7

proof or you just making assumption?

Not sure if it was mentioned but Intel does a Tick Tock process of rolling out their upgrades. Tock rollouts are where Intel has changed the Architecture (Usually more Transistors). Ticks are where Intel changes the die. They do this to test a known good architecture and manufacturing technique on a smaller die. This is why every one says to get a Tock chip as apposed to a Tick chip.

That said, Intel has changed a little with their 4th Gen chips in that they have added graphics to them. And as mentioned this might be where they will focus their changes in the future.

Most games perform better with Intel CPUs. The difference can be very small if the game is not very CPU dependent or it can be rather significant in CPU dependent games like SimCity. If I remember correctly the different in performance in that game is around 15% - 18% when comparing a stock speed FX-8350 to a stock speed i5-4670.

Skyrim is a game that overwhelming favors Intel so it is rather unique. When it was 1st released the game was benchmarks with a Sandy Bridge i5-2500k and Bulldozer FX-8150. I forget what high GPU was used; nVidia GTX 580 maybe?? Anyway, the performance difference was over 30% in favor of Intel.

In terms of video encoding, the FX-8350 has proven to be a bit better than the Intel i5-4670k at stock speed. I'm guessing a 10% performance difference... sorry, it's been a while since I looked at encoding performance charts...
