X-Gene 1, Atom C2000 and Xeon E3: Exploring the Scale-Out Server World
by Johan De Gelas on March 9, 2015 2:00 PM ESTMySQL Performance
For testing real-world SQL server performance with our homemade stress-testing software (vApus), we need a powerful client with lots of bandwidth. That kind of client was not available to us inside the network where the HP Moonshot was located. So we went back to the MySQL Sysbench utility. Sysbench allows us to place an OLTP load on a MySQL test database, and you can chose the regular test or the read only test. We chose read only as even with a flash device, Sysbench is quickly disk I/O limited.
The main reason why we tested with Sysbench is to get a huge amount of queries that only select very small parts (a few or one row) of the tables, so we can see how the SoCs behave in this kind of scenario. Sysbench allows you to test with any number of threads you like, but there is no "think time" feature. That means all queries fire off as quickly as possible, so you cannot simulate "light" and "medium" loads.
The response times are very small, which is typical for an OLTP test. To take them into account, we are showing you the highest throughput at around 3 ms (2.8 ms to 3.3 ms). We tested with 10 million records and 100,000 requests
Again, the X-Gene is nowhere near the Xeon E3, but rather a competitor for the Atom C2750. The Xeon E3-1230L v3 outperforms the Xeon E3-1265L2 v2 by a small margin, despite the lower base clock.

xgene is not looking so great. Even if it is 50% more efficient as they promise they'll still be behind Atom.Samus - Monday, March 9, 2015 - link
HP Moonshot chassis are still *drool*Krysto - Monday, March 9, 2015 - link
The main problem with the non-Intel systems is not only that they use older processes compared to Intel, but that they use older processes even compared to the rest of the non-Intel chip industry. AMD is typically always behind 1 process node among non-Intel chip makers. If they'd at least use the cutting edge processes as they become available from non-Intel processes, maybe they'd stand a chance, especially now that the gap in process technologies is shrinking.Samus - Monday, March 9, 2015 - link
AMD simply isn't as bad as people continually make them out to be. Yes, they're "behind" Intel but it's all in the approach. We are talking about two engineering houses that share nothing in common but a cross licensing agreement. AMD has very competitive CPU's to Intel's i5's for nearly half the price, but yes, they use more power (at times 1/3 more.)But facts are facts: AMD is the second high-tech CPU manufacture in the world. Not Qualcomm, not Samsung. It's pretty obvious AMD engineering talent spreads more diversity than anyone other than Intel, and potentially superior to Intel on GPU design (although this has obviously been shifting over the years as Intel hires more "GPU talent.")
AMD in servers is a hard pill to swallow though. If purchasing based on price alone, it can be a compelling alternative, but for rack space or low-energy computing?

AMD doesn't even make it in top 10 semiconductor companies in sales. Qualcomm is three, Samsung semicondutors six and Intel almost ten times the size of AMD.Outside of the gaming consoles they are being completely overrun by competition.

I'm sorry, at one point I was an AMD fanboy, back when they actually deserved it based on their products, but you just sound like an apologist. Facts are the facts, FX processors aren't competitive with i5's in performance or power or performance/$ because they get smacked so hard they can't be cheap enough to make up for it. Their CPU designs are woefully out of date, their APU's are bandwidth starved and use way too much power to be useful in the one place they'd be great (mobile), and their lagging process tech means theres not much better coming on the horizon. I don't want to see them go, but at the rate ARM is eating up general computing share, it won't be long before AMD becomes completely irrelevant. It will be Intel vs. ARM and AMD will be an afterthought.xenol - Wednesday, March 11, 2015 - link
Qualcomm is used in pretty much used in most cell phones in the US to the point you'd think Qualcomm is the only SoC manufacturer. I'm pretty sure that's also how it looks in most of the other markets as Korea. Plus even if their SoCs aren't being used, they're modems are heavily used.If anything, Qualcomm is bigger than AMD. Or rather, Qualcomm is the Intel of the SoC market.

[Response to myself since I can't edit]Qualcomm's next major competitor is Apple. But that's about it.
Also I meant to say other markets except Korea.

Bear in mind that the Atom parts were commercially available in 2013, so they are by no means brand-new technology and the 14nm Atom upgrades will definitely help power efficiency even if raw performance doesn't jump a whole lot.Anandtech is also a bit behind the curve because Intel is about to release Xeon-D (8 Broadwell cores and integrated I/O in a 45 watt TDP, or lower), which is designed for exactly this type of workload and is going to massively improve performance in the low-power envelope sphere:
