Eight Core
« on: Dec 12, 2011, 02:19 PM »
Saw this: http://www.cyberpowerpc.com/system/AMD_Eight_Core_Configurator/

Is it a good deal?   I have a fresh, legal copy of Windows7 Professional 64bit ready to go, (Yay for free software from school!) and can port over my data drive from my current PC.   I would probably upgrade the Video Card and Power Supply, but Might wait on the video card and do it in a month or 2... depending on what I am able to afford.  I COULD spend up to 1K, but my Wife will prob kill me since we have Baby #2 on the way. 

   8 Cores is really what grabbed my interest here.   I figure I won't have to upgrade again for years.   My current PC is only 2 cores and still runs pretty well, but it's starting to slow down and the USB slots on it are mostly all broken thanks to my son jamming things into them.  I've had my PC now for 3 years, so that's not too bad.

suck a lot of power....not as good as the i5-2500k ....cheaper though.

There is an i5-2500K model there for the exact same price.   Isn't an i5 only 4 cores?   And does that really matter?

I am pretty sure SWTOR is not ptimized for 8 core utilization, I would be suprised if it is even optimized for cores above 4. Although 6 core procs have been out awhile there are problems with over parallelization giving diminishing returns as their is a limit to how much performance gain you get from doing it and the loss of single core performance in order to achieve a faster net of computing power. Temperatures and power consumption would be the second problem. I would focus on getting the best 4 core (and I dont know if you are an AMD enthusiast or not) but I am a hardcore intel fan and always will be and will tell you that the price is not worth getting an AMD. The only real benefit I can see is the larger video and memory bandwidth you would get, but you would need a high end SLI configuration and a larger amount of ram in order to utilize it (and even then the game does not use that much memory to begin with), and as of now SWTOR doesnt even benefit from them as much due to their lack of DX10 or 11 support.

Most of this is just because SWTOR does not benefit from the hardware that I would not recommend it, that being said I would focus more on an proc with a large amount of cache (the 8 core has the same amount as most 4 cores, 8mb which is pretty standard on good procs). Benchmarking has shown that dual cores do significantly better than singles, and altho much smaller 4 cores has an improvement over 2, but at 6 its fairly negligible over 4 cores (mostly due to lack of utilization by software). So I would assume that 8 cores will not be a huge increase, and at that price point I would think its a lower end AMD. Usually instead of getting a cheaper price point on the newest technology I like to get the best and most expensive version that just went in for a big price cut. It might be 6 months old, but tbh the manufacturers dont really make a huge improvement in 2-3 years its all marketing.

You can run bench results against different cpu's and you will notice that the new AMD FX series seriously underperforms...becuase as much as they claim it is a 8-core, technically its really 6-core with a much slower FPU ....making the 4-core and even dual cores outperform it. Also no game really uses more than 4 cores so pretty useless.

the i5-2500k even outperforms the i7's in gaming. But honestly its a personal preference, though i would check out the reviews for the AMD FX chips before purchasing.

Pretty much once you have 4 cores, it comes down to clock speed and cache. If you really want to outperform, use liquid/gel/pressure cooling and OC the proc you will see huge gains. Besides that buy a proc with better clock speed than 3.1 GHz thats about the best you can do.

These guys covered it pretty well.

I'd take a hard look at exactly what you are interested in doing with your computer. Not much can actually take advantage of all 8 cores at once outside of bench-marking programs. Even if you consider heavy multi-tasking, test results show in most cases the extra cores don't make that much difference.

Back in the day, going from a single core p4 or some-such to something like a Core2Duo was a massive upgrade, with a tangible "faster" feel to using your computer. You won't really experience that if you upgrade again to simply more cores.

I'll put in another plug for the i5-2500k. Stock is 3.3 ghz under load, but where this thing really shines is when you overclock it. Overclocking has become so simple with modern motherboards, it is just a matter of changing up a few settings like the multiplier (which is unlocked in this one, that's what the "k" means) in the bios.

With a cheap $30 after market cooler, I pushed my cpu to a 4.5ghz 24/7 overclock, and temperatures have been rock solid even when I'm taxing my cpu pretty heavily. You'll see a much bigger impact from this speed bump for most applications/games than the extra cores.

If you are talking about gaming, most likely your performance bottleneck is going to be your GPU anyway, so your money would be better spent on a beefy graphics card. (Q1 of 2012 is supposed to be big for next gen GPUs)
