 Posted: Thu, 14th Feb 2013 11:42 Post subject: 4 cores vs 6 cores ? |
|
 |
I am thinking of building myself a new system from scratch and i am wondering, if or what the real difference of current generation 4-cores to 6-cores was and if its, for me as a gamer, warrants the extra cash for the 6 core or just go with a 4 core instead ?
I am currently running a i7 920 @ 3ghz.

You'd have to make a list of apps/games you use/play first. We'd also be entering the realm of "future proof" which is very subjective. Will the new consoles make games demand more than four cores? Will many applications utilize four cores? Many questions, difficult decisions.

i'm a pure gamer and don't use any applications, really.

No game afaik make use of 4 full cores. Most use 2 cores, separating obvious engines for threads that aren't synch-sensitive. Then there are games that throw some process to a third CPU which is never maxed out (or goes past 50% even) while the 4th core is used for the OS.
It's still too early for 6-core (unless you encode x264) CPU's, but sure, it doesn't hurt. You'll be somewhat future proof and can run more apps + games in parallel without CPU bottlenecking, IF the thread/core scheduler work properly.
A 6-8 core top AMD CPU can't keep up with the last gen 4-core (some with HT) 2500k-2700k and upwards, esp. not in games.

hah, wait and see for now.
next gen consies will have a low-clocked 8-core (AMD Jaguar 8x1.6ghz)
what will this mean for PC gaming? what will this ridiculously low clock speed mean for console games? will we see more parallelism in future games? can a quadcore with high clocks work with games optimized for low-clocked octacores?
I'd like to know those answers myself but I lack the knowledge.

INTEL Core i7-3820 "Sandy Bridge E", 4x 3.6GHz, Socket 2011
should be a fine cpu for now, no ? I chose the 2011 socket, because it should be more future proof, right ?
also thought about getting :
GIGABYTE GA-X79-UD3, Intel X79
Socket 2011 • Four Channel DDR3 (2133MHz) • 4x PCIe 3.0 x16 (CrossFireX/SLI), 2x PCIe x1, 1x PCI • 4x SATA II 3GB/s, 6x SATA III 6GB/s, RAID 0/RAID 1/RAID 5/RAID 10, 2x eSATA • 1x 10/100/1000Mbps LAN • 8x USB 2.0, 2x USB 3.0 • ATX
GEIL Evo Corsa Quad Channel 16GB PC3-17000 2133MHz C11
4x 4GB, DDR-DIMM, PC3-17000 (2133MHz), 11-11-11-36, heatspreader
CORSAIR Performance Pro Series, 128GB SSD for windows and day to day use apps
2.5", read: 550 MB/s, write: 440 MB/s • SATA III 6.0Gb/s
OCZ Vertex 4 Series SATA III 2.5" SSD, 512GB for games
2.5", SSD controller: Indilinx Everest 2, MLC, 1GB cache, read: 535 MB/s, write: 380 MB/s • SATA III 6.0Gb/s
i have a corsair 850 psu, which should be ample enough for now and until the day it crashes ^^ and for now i'll keep using my 560ti, until later anyway.
Should be a nice setup no ? Or is anything i listed known to be of bad quality/had bad reviews/someone had bad experience with ?

No existing Intel socket is future proof (as usual when it comes to two-generation Intel sockets):
| Quote: |
Haswell is expected to launch in three major forms:
(1) Desktop version (LGA1150 socket): Haswell-DT - the one we're interested in
(2) Mobile/Laptop version (PGA socket): Haswell-MB - for laptops
(3) BGA version - CPU's are soldered directly on the boards.. low budget/ultrabook/tablets.
New sockets — LGA 1150 for desktops and rPGA947 & BGA1364 for the mobile market. It is possible that Socket R3 will replace LGA 2011 for server Haswells |
On the other hand you should have no issues skipping Haswell. I can't see the need for Haswell for those of us with high performance Sandy's (2*00K's) and Ivy's (3***K's).
Socket 1150 will be the only socket for the entire Haswell Desktop series. The sequel to Haswell, Broadwell, will apparently use 1150 as well. Broadwell seems to follow the same path of the Haswell: lowering power usage as much as possible while performance will be in a lower focus, with the main difference being that it's shrunk from 22nm to 14nm.
I guess the utter failure of the last 3-4 generations of AMD CPU's have given Intel a chance to focus on other things than creating powerful performance flagship CPU's. The upcoming AMD CPU's will still be build using Bulldozer cores slightly updated (called Piledriver). The guy (Jim Keller) that left AMD after working on and designing the industry winner Athlon64 is back but his work will take ~2 years to be implemented since the piledriver and follow-up to that was already basically finished when he jumped back on board, so 2 gens forward should pass before we see Jim Keller trying to rescue the AMD CPU division.
Chances are ATI will be sold if AMD fail to liquidate enough for operational costs.

i'm not much into overclocking.

Crysis 3 atleast uses 4 cores, also makes use of HT which is VERY rare. But in general you should just get 4 core. AMD bullcraps and stuff loses even to i3 desktop in processor intensive games  I swapped 5Ghz 2500K to this 5Ghz 2700K, no difference in games, expect crysis 3, also programs which uses HT properly, gives pretty big boost compared to 2500K. Also DO NOT buy 3820, you cant overclock it like K models, also its not even better than 2600K. 2011 socket will get IVY-E processors, but then its gonna be dead socket. 2011 socket also is more for guys who edit, you are not gonna see any improvements in games compared to 1155, and when games starts to use 6 cores properly, the 2011 stuff is ancient crap.
