Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

My decision:

1. ASUS P8Z77-V.
Reasons: Wifi ready, 4 Sata III, HDMI, DVI, PCI Express 3.0.

2. Core i5 3570K.
Reasons: Ready for overclocking if I want to do it.

3. SAPPHIRE 7850 (I can swap to built in VGA when run MAC OS X, it supports Intel HD4000)


These three are the main things to decide.

So if I share your your private data without having your permission it is not theft? Or your money? Or whatever valuable you have?
Don't bother to answer that, just think about it, I will not answer to you anyways.

Core i5 3570K is really great, I must buy it.

The Apple Mac Pro can have 2 CPUs, 12 core processing.
http://www.apple.com/macpro/specs.html

Can I build similar system with normal intel or amd motherboard?

All the way back around to 'can I use a server CPU' again.

You can build 6core/12thread intels (LGA 1366/LGA 2011), but they are hardly 'normal' even if they arent really 'server' level hardware. Also wayyyy to expensive for the minor (if any) performance improvement over a 4 core i5/i7. A 6 core LGA 2011 CPU is $550 US+, LGA 2011 motherboards are more expensive and LGA 1155/AM3+ boards, etc..

To get 12cores you have to use server level hardware, with multipule CPUs in the case of intel (as intel doesnt have a 12core CPU at all). Not worth it, and it would be slower for desktop use than a 4 core i5/i7 or an AM3+ CPU.

Are you saying >1 CPU must use server board?
For desktop applications like playing 3D games,
>1 cpu might not be better than normal desktop single cpu?

A computer with 256 cores will not be able to add one and one into two any faster than one with a single core. It'll probably be slower in reality.

The advantage of multiple cores is the computer's ability to do multiple operations simultaneously. 16, 32, or more cores are great when you have, for example, thousands of instances of apache providing MMS to thousands of mobile clients, or hundreds of thousands of SQL connections and queries coming in every few minutes.

In order for a single program (like a video game) to take advantage of this ability, it must be designed to do so. There are (almost) no video games designed to take advantage of the large number of cores you are talking about, so for gaming the extra hardware is wasted. There may be games designed to take advantage of as many as six cores, but probably not many. Most newer games will take full advantage of two cores in a PC, some of them up to four.

So, the answer to your question, "Can I use server hardware to build myself a desktop PC" is, "Sure, you can, but it's an ignorant thing to do, unless you just happen to have some server-grade hardware lying around not being used."

Somebody please close this thread.

Intel ivybridge cpu now comes with 4 cores.
I notice that when benchmarked with AMD 8 cores cpu, intel's cpu is better in 3D games like crisis 2,
but in Winzip/Winrar, AMD is better.
Does it mean winzip/winrar can take advantage of multicore, more than 3D games?

My objective is to construct a poweful PC for gaming as well as doing complicated simulation like ANSYS, Mathlab, and for
3D drawing using Solidworks.

I think the 3rd generation intel CPU plus a GTX660 VGA card can do these jobs for me.

Formerly known as Jaguar, the Cray (CRAY) supercomputer at the DOE's Oak Ridge National Laboratory got a major upgrade and an appropriately intimidating new name.

Titan replaced its predecessor's 224,256 central processing units (CPUs) with 299,008 faster CPUs made by AMD (AMD, Fortune 500), along with 18,688 graphics processing units (GPUs) made by Nvidia (NVDA). The GPUs serve as accelerators to the CPUs. That's why Titan has just a third more central processors and the same number of computing nodes and cabinets as Jaguar, but delivers 10 times the performance.
For a supercomputer, the more CPU the better?
Why?

If the fastest supercomputer in the world is using AMD's processor, it must be good, better than Intel's processor?

That doesn't logically follow.

Clearly there is some advantage to using AMD CPUs when tightly coupling a large number of CPUs to work together on a single problem.

When only one or two CPU packages (of a few cores each) are used in an ordinary system, the comparison between AMD and Intel is based on other factors.

Being that we're talking about a government project, the "clear advantage" was probably a lower bid.
