Great CPU VS. Average CPU and Average GPU

[Mideval135]

I was doing some browsing online, and came across one of Intel's newest CPU's. It was a Xeon Phi Processor 7295 with 72 cores at 1.5 GHz. I know it's not necessarily designed for gaming but with that many cores, one as wondering what it could do. CPU's are for multitasking information purposes where GPU's are for only graphics calculations and rendering right? Why couldn't this 72 core CPU do the same as say a 4 core 8 thread CPU and 1080 GPU? Is this possible or would there be hardware restrictions?

CPU cores != GPU cores

CPU's can do graphical work, but GPU's are much more specialized and better at it.  It's like the difference of painting a fence with a roller versus a toothbrush.

It should be noted these CPUs are designed with specific tasks in mind. These are essentially FMA3/AVX-512 powerhouses, with minimal other stuff required to get it working. The generation before it essentially had atom cores outside of the FPU part. It will suck at most other things. If all you care about is FP64 throughput, there is nothing else like it. Nothing AMD makes comes close in either CPU or GPU forms. There might be some nvidia pro level cards that could be comparable, but certainly for Titan and lower cards, forget it.

As has been said, CPU's and GPU's are two very different things and are pretty rubbish at doing one anothers jobs.

 

As for a Xeon Phi processor, it's a complete waste of money unless you're using a specific program capable of taking advantage of it. So unless you happen to own a datacentre or are a scientist running datasets...it's not meant for you.

 

If you want to game, stick to consumer processors and graphics cards.

That makes sense @Ezzy-525, @TVwazhere and @porina. I already have my gaming rig. I definitely do not have anything to utilize that Xeon processors capability. I was mostly just curious if it was feasible.

you could use it for gaming but you wouldn't want to with a base clock of 1.5 and turbo of 1.6. You'd be better with a cheap pentium

Did not Linus or someone do a video playing a few games on a 42 core CPU and saw how many cores they were actually using.

Gaming all you need is 4 cores and 8 threads and a fast IPC and high GHz rate then you are Golden!
