Xeon phi = Red Rocket-X?

[herb]

hey so i was rewatching the red rocket x video and i had an interesting thought. intel used to make those xeon phi pcie cards with like 60 cores or somthing crazy like that. now these cards are not just plug and play, you need to program them to be utilized for specific tasks. but lets say utilizing it was no big deal, could you use it as a replacement for the red rocket x? if you look at the pcb of the red rocket x and a xeon phi card they dont look that different and im assuming that the xeon has more processing power. The xeon phi is also way more readily available and they only go for $300-$400 vs the $1500 that a red rocket x would cost on the used market.

 

so i guess what im asking is: would the xeon phi be able to function like the Red rocket x? and would it be faster?

it doesn't really work that way, there completly different under the hood.

Not without signifant software to make it work, it won't be plug n play.

the red rocket x and a xeon phi are essentially the same thing are they not? they are both co-processor cards that are meant to pick up where your main computer lags behind and they both are designed to accelerate heavy tasks. the main difference from my understanding is that they are marketed to different types of workloads.

 

im not saying that your wrong, everything i have said is completely theoretical, but do you know what the differences are?

yeah i know. i already said it wouldnt be

There are tons of different types of co processors, they aren't all the same. There all made for a specific task, and the red rocket and the xeon phi are made for different workloads.

i thought that the xeon phi was a bunch of cores and ram on a PCB and that they could adapt to all types of workloads. if that's true, it shouldn't make a difference of the type of work load it does right?

Well its mostly full x86, but its made to do vector instructions, and has much more avx512 than the normal x86 cores. You kinda have to make your program to use the xeon phi's, it normal won't work well with x86 programs without a good amount of modifying the programs.

but your saying that it could be done?

Unless they happened to be exactly the same, and there wasn't some custom identifier on the Red card that the software validates before accepting to run its code on it (almost certainly is if they are the same) you'd be having to rewrite the software on your own... without knowing at all how it's supposed to work nor having access to the toolchains used to build software for it.

If you are good enough, anything can be done.

BTW, used Xeon Phi cards are now under 40$ US. I made a thread about it recently. I picked one up, haven't quite figured out what to do with it yet (it's not meant to really function under windows) but it's cool to own a piece of history
