Anyone know when we might see the Intel C2750 successor?

[hungarianhc]

I love my Intel Avoton chip, but I wish it booted up faster, I wish it had better single threaded performance, etc. Has anyone heard when we might see an update to this line of chips?

The Avoton range was designed with scale-out datacenters in mind. Webservers are easy to scale and multithreaded.

What you wish for is something like the Socket 1150 lineup which isn't even more expensive.

Probably late Q3 at the earliest.

Haha - thanks for telling me what I wish for. I actually don't want a Haswell chip. I like my 8-core C2750, which is completely fanless. I'd just like the next iteration of it when it comes out.

The Avoton was itself a fantastic boost over prior generation Atom processors. You're not likely to see substantial similiar jumps in the future because Intel's other consumer grade CPU's live in that realm.

So you can always get yourself a nice low end Intel processor and see about doing a fanless design.

I repeat, if you want singlethreaded power, then you don't want a 8, 16, 24, 60 core monster. You want a nice socket 1150 CPU with 2 or 4 cores and 2, 4 or 8 threads then. These have singlethreaded power without running hot.

I've got Xeon E3 v3's with the integrated graphics (in use as well) here. They use less than 70W under _full load_. A NAS is seldomly under full load, hence passive cooling isn't all that neccessary. When idling, that CPU uses 2W. The fan doesn't need to spin at a usage of 2W. Even if it spins, it doesn't need to spin fast and audible.

Per my original post - not looking for a lot of single threaded power. I really like the chip, which I think was evident in my original post. I'm just excited for the successor, since I like it so much. I know... weird.

The fan on the E3 in my X10SL7-F is running at 1500rpm. I have never seen it running at less than 1100rpm. How do you have your system set up so that the fan sometimes doesn't run at all?

More != A lot

In any case, it looks like the Xeon D will be the successor to Avoton. It is expected to go down as low as "under 20W," which is exactly where the C2750 CPU is right now. Intel has even released some preliminary benchmarks comparing Xeon D to Avoton, and it's showing to be about 3.4x faster, about 1.7x faster per watt.

I currently have a fanless C2750. Looking forward to the time when I can get a fanless Xeon D!

Update: The CPUs are up on ARK. Looks like we're starting w/ 45W parts.

 

[marbus90]

You can always limit your singlethreaded power back down with the 35W TDP parts on S.1150. It's a bad idea*, but possible.

* because the CPU doesn't use the full TDP all the time. My Xeon E3-1225 v3's are specced for 84W TDP and yet use less than 50W including 4x8GB RAM - at full load. A standard issue Core i3 would probably be at <30W easily - at full load. The Quadcore Xeons idle at 2W and a home FreeNAS box would idle most of the time.

 

[Ericloewe]

Early benchmarks suggest that Xeon-D actually outperforms a Xeon E3 1230 v3 in singlethreaded workloads.

It's very likely that that's not full load. An Intel CPU with an 84W TDP simply doesn't take half that amount of power at full load. You may be missing out on some watts by not exercising the graphic subsystem as part of your load testing, but I'm skeptical that that would make up 40 watts.

Yeah, the processor might be 100% busy, but it might have execution units idling.
Artificially loading a modern CPU or GPU for maximum power consumption is a surprisingly complex task.

Indeed, I only ran boinc/world community grid on there, the GPU part was bored with the Win8.1 desktop. But that part wouldn't be used on a FreeNAS anyway...

This resolution makes a whole lot more sense to me than the Avoton itself ever did. The C2750 in particular seemed to be nipping away at the low-end Xeon niche.

A lot of what's going on in the marketplace is somewhat irrationally driven by the fear of ARM-in-the-datacenter. The higher performance of a smaller number of cores is somewhat preferable for many workloads, and I'm glad to see Intel is making a serious foray with the D.

Bumping an old thread because it's what shows up on the Google and is still a relevant question.

Looking through the list of Xeon D chips, I don't see anything below 35W TDP, and they're pricey CPUs. I did a fresh Ubuntu-based NAS build back in February and worried about going with the C2750 because I didn't want the next big thing to drop and me be left wanting.

On the good side, that hasn't happened in the ensuing 4 months. On the bad side, that hasn't happened. This C2750 is a nice CPU, and I hope Intel will continue iterating in this space.

They will not. Atom is dead. I'd say this is why we haven't seen a successor to the C2750 in the nearly three years since it was released.

 

[Dall]

Thanks for sharing that link. I should have done more Googling before posting. On the bright side, I can stop worrying about a new Atom chip dropping. It also makes me feel good about my C2750 versus C2550 choice.

The C2750 should treat me well for the foreseeable future. And when the time for upgrade comes along, I'll probably be looking at a Xeon.
