What makes this cpu better?

PS3toPC · Oct 25, 2014

I looked at some recommended cpu's for some games and i looked at planetside 2, and the results for the Intel Core i3-4130 Dual Core 3.4GHz is reported to get about 34 fps at the minimum and 51 fps as the average, however my current cpu can't even get to 30 fps in a very un populated area on the game, and my current cpu is a quad core @ 2.66 GHz (intel xeon x5355), i know its a old cpu but it's got more power if you add up all the cores power together, could it be to do with hyper threading? i'd like to know more about hyper threading too.

Current games don't really support hyper threading and most games only uses two cores so your extra cores won't make a difference. The architecture is different as well. Single core performance is better on the i3 4130 than your cpu.

Hey,

when benchmarks for CPUs are carried out for gaming it's a common practice to pair the given CPU with the best (or at least one of the best) GPUs currently available to avoid bottle-necking. So when comparing your those results with the ones you get you should make sure you are using the same tier GPU and make sure you pay attention on all details listen in the benchmark results (overclocking etc.).

Its not as simple as add up the ghz of the cores, number of cores and ghz only matters if your comparing the same generation of CPU. The i3 4130 is much newer than your xeon and is vastly superior due to architectural upgrades.

Most games don't use all of a CPU's processing capabilities and may use mainly TWO of them or slightly more. Thus, the per core performance of the core is more important.

And of course there's a FREQUENCY difference. Even if they were identical CPU's the faster one will process more information. Thus on that alone you get:

3.4/2.66 = 27% faster

If we assume an architectural advantage of the newer CPU of say 25% then we get a 58% advantage per core ignoring the i3's hyperthreading which could add up to 30% more but only if the program could use that (which it likely can't).

NOTE:
Both CPU's should be able to convert a HANDBRAKE video at almost exactly the same speed. If we factor the FREQUENCY and the ARCHITECTURE (guessing on difference), and HT advantage we get:

1.27 x 1.25 x 1.3 = 2.06

THUS, each i3's physical cores can process up to the same amount of data as TWO of the Xeon's assuming a program can use it all.

HYPERTHREADING:
This is a technique of using the SAME CORE by running a separate instruction through it when the core is still waiting for the next batch of data.

It's like having a bunch of smarties in both hands and sneaking in a few from the left hand to eat (process) when the right hand reaches down to get more.

HT can't always be used if the code order (in-order vs out-of-order) doesn't allow for it of the program can't use more than a certain number of threads period.

Nomenclature:
2C 2T - this means only two physical cores and no hyperthreading (read as: two cores, two threads)

2C 4T - this means two physical cores with hyperthreading (read as: two cores, four threads). Thus, each core can hyperthread, or run another instruction as explained above when programming allows.

Thank you all, this is the most support on a thread that i have had, so thanks big time

, i see now what i needed and now i feel at rest , however i do have a 'bonus question' i guess, i often render videos using sony vegas with pc, would the upgrade in cpu help out this?
