Dual CPU Database Server Comparison

A gigantic market
For those of you who are relatively new to databases, I will be providing some information for you shortly and comparing it to the more popular, but much smaller, gaming market.Database software sales continue to be a barometer of the overall IT market health. Database servers are, without any doubt, a critical part - the beating software heart - of many companies.
The market of relational database software was worth $7.1 billion in 2003 according to research firm, Gartner. Up to $46 billion is spent in the Servers (hardware) market, and while a small portion of those servers is used for other things than running relational databases (about 20% for HPC applications), the lion's share of those servers are bought to ensure that a DB2, Oracle, MS SQL server or MySQL database can perform its SQL duties well. So, in essence, IT people are spending over $50 billion on databases and servers.
According to a very recent report, about $15.8 billion of the $46 billion server market is spent on PC servers. AMD's Opteron has conquered about 5.3 percent of this PC server market, but the remaining 94.7 percent belongs to Intel's Xeon.
For comparison, the total PC gaming software and hardware market is about $1.3 billion (according to IDC), while the complete gaming market is worth $3.4 billion.
At about 36 percent, the DB2 database is the number one database. Since it is available on many operating systems, and both x86 and 64 bit x86 archtitectures are supported, it received our special attention.
MySQL is, by far, the most popular relational database in the low end of this market and is steadily growing in features and market share, taking away market share from the big players.

About SLES9 and NUMA: NUMA is also supported by Linux kernel 2.4.21 and it boosts performance only a tiny bit. The reason are the very speedy HT links which keep latency at a minimum.It is still possible that kernel 2.6 NUMA support is far better of course, but I doubt it makes a difference for quad or dual systems as there is only hop in quad systems. With two hops (8 CPUs) from CPU 1 to 8 for example, this will become important.

A TYPO:So for now, the Opteron has an advantage still, but it ***can*** /can't/ knock out the Xeon, as it could have a few months ago, before the Xeon Nocona arrived.

There have been enough benchmarks on the web for a long time which show that Opteron generally wipes Xeon's a$$ hands down, and scales far better in multi processor configurations. The latest Xeon is nothing special compared to prior versions and will no doubt preform better mostly due to its increased clock speed. Xeon will never be better than Opteron no matter how much cache and tweaks Intel adds.Maybe Intel's next server architecture will be something to woo, but that's a ways off.

as a long-time reader of aceshardware, i'll be the first to welcome Johan here, great first article. keep them coming!!!!HardwareD00d - Thursday, December 2, 2004 - link
I don't think there are enough variations of the way requests are handled to make a realistic conclusion for either chip. I'm sure you could create a situation where Intel bests AMD in My Sql, and vice versa. This article really needs more benchmarks and more in-depth analysis. Still, it provides enough information to conclude that both Xeon and Opteron have their strengths and weaknesses.mczak - Thursday, December 2, 2004 - link
Nice read. I really think though you should have used SLES 9. Not only does it use kernel 2.6, but it's also NUMA-aware (and DB2 should specifically support it, though it might not have been released yet). SLES 9 also ought to be faster especially on x86_64 due to newer compiler (not that it would matter much with precompiled databases, but every bit counts...). Though for 2-cpu boxes, NUMA might not be that important - but it's safe to predict a landslide victory for a 4-cpu opteron with NUMA support vs. a 4-cpu xeon box. Xeons simply don't scale to 4 cpus, intel might sell them but they are useless (especially since the Xeon MPs are still limited to 400 (or was that 533?) Mhz FSB.A pity though the quad opterons don't support ddr-400. I guess manufacturers decided it's more important to have a boatload of ram slots than fewer slots (with shorter traces) with higher speeds...
And btw, where are the 90nm Opterons? AMD's latest roadmap shows them as available in 2004, which doesn't leave too much time...

Bogus conclusions about IBM tests IMO. From the

DB2.
It has not.
You fail to specify that this is comparing the _32 bit_ mode for the Opteron. IF you compare the Nocoma performance to the Opteron 64 bit capability...it sweeps the the Nocona in all tests.
The true conclusion is that based on the results in the article, for neither of the databases tested do *any* of the Intel processors compete with the Opteron.

Randomized benchmarks are hard to verify as well. You could get a "good" distribution that really takes advantage of cache locality while another randomization may be very cache unfriendly. I agree with #5 to a degree. A database that fits entirely inside of RAM isn't very interesting, ultimately.Still, I am happy that AnandTech is going down these paths of benchmarking instead of just being about Doom3, HL2, and FarCry like most other sites. I eagerly await further database benchmark articles.

#5 - Since when do top tier e-commerce cites compare to mid-level company database users as the beginning of the article mentioned?My company is an engineering firm that does custom electronics. Our database server handles all the transactions for our Inventory/MRP system which is mostly reads. These benchmarks are very appropriate. I wish I could have convinced my boss to go Opteron. Its funny, they had Athlon MP's before and then switched to Xeons when Opteron was out. Go figure.
Anyway, great article. I'm not IT guy by any stretch, but I enjoyed the article.
