The Intel Xeon E7 v2 Review: Quad Socket, Up to 60 Cores/120 Threadsby Johan De Gelas on February 21, 2014 6:00 AM EST

It is generally accepted as common knowledge that the high-end RISC server vendors—IBM and Oracle—have been bleeding market share in favor of high-end Intel Xeon based servers. Indeed, the RISC market accounts for about 150k units while the x86 market has almost 10 million servers. About 5% of those 10 million units are high-end x86 servers, so the Xeon E7 server volume is probably only 2-4 times the size of the whole RISC market. Still, that tiny amount of RISC servers represents about 50% of the server market revenues.
But the RISC vendors have finally woken up. IBM has several Power7+ based servers that are more or less price competitive with the Xeon E7. Sun/Oracle's server CPUs have been lagging severely in performance. The UltraSPARC T1 and T2 for example were pretty innovative but only performed well in a very small niche of the market, while offering almost ridicously low performance in any application (HPC, BI, ERP ) that needed decent per-thread performance.
Quite surprisingly, Oracle has been extremely aggressive the past few years. The "S3" core of the octal-core SPARC T4 launched at the end of 2011 was finally a competitive server core. Compared to the quad-issue Westmere core inside the contemporary Xeon E7 , it was still a simple core, but gone were the single-issue in-order designs of the T1 and T2 at laughably low clock speeds. No, instead, the SUN server chip received a boost to an out-of-order dual-issue chip at pretty decent 3GHz clocks. Each core could support eight threads but also execute two threads simultaneously. Last year, the Sparc-T5, an improved T4, had twice as many cores at 20% higher clocks.
As usual, the published benchmarks are very vague and are only available for the top models, the TDP is unknown, and the best performing systems come with astronomic price tags ($950,000 for two servers, some networking, and storage... really?). In a nutshell, every effort is made to ensure you cannot compare these with the servers of "Big Blue" or the x86 competition. Even Oracle's "technical deep dive" seems to be written mostly to please the marketing people out there. A question like "Does the SPARC T5 also support both single-threaded and multi-threaded applications?" must sound particularly hilarious to our technically astute readers.
Oracle's nebulous marketing to justify some of the outrageous prices has not changed, but make no mistake: something is brewing among the RISC vendors. SUN/Oracle is no longer the performance weakling in the server market, some IBM Power systems are priced quite reasonably, and the Intel Xeon E7—still based on the outdated Westmere Core—is starting to show its age. Not surprisingly, it's time for a "tick-tock" update of the Xeon E7. The new Xeon E7 48xx v2 is baked in a better process (22nm vs 32nm) and comes with 2012's "Ivy Bridge" core, enhanced for server/IT markets to become "Ivy Bridge EX".

colonelclaw - Monday, February 24, 2014 - linkI would like to see V-Ray benchmarked. It's fast becoming an industry standard across a number of 3D industries (started in ArchVis, is now moving into animation feature films and FX)
PowerTrumps - Sunday, February 23, 2014 - linkThe author is misleading with statements and data not to mention @Brutalizer comes across very knowledgeable but only backs up claims or Oracle server performance with platitudes and boasts.
Starting with the article - comparing various cores regardless if you adjust the frequency is misleading. You need to normalize the values to show what the per core improvement is. To stay with sockets is useless and lazy. Yes, Intel customers buy servers by the socket but to understand what they are really gaining this is a much better metric. To say there is a 20 or 30% gain when there might be 50% more cores tells me the per core performance is actually lower than Westmere. This is important when using software like Oracle that would price a 15 core socket at 7.5 or 8 Oracle licenses. For software licensed by the core, customers should demand the highest performance available otherwise all you do is subsidize Uncle Larry's island. For the Power comparisons in the SAP benchmarks. You compare a 60 core to a 32 core N-1 generation Power7 server. Since Power servers scale almost linearly by frequency, the 8 core @ 4.22 GHz is 54,700. If we extrapolate that to a 4 socket or 32 cores we would be around 200K SAPS. That is quite a bit more than the 60 core Dell. Also, you could deploy a Power server as a standalone server. Nobody would deploy a mission critical workload on a standalone x86 server. Yes, I'm sure somebody will argue with me and say they do and have done it for years. Ok, but by and large we know they are always clustered and used to scale-out. Secondly, you claim how expensive the Power servers are. When was the last time you priced one Mr De Gelas? You can get a Power7+ 7R1, 7R2, or 7R4 that has price parity with a typical x86 price that includes Linux and VMware and comparably equipped. The 710 and 730 servers would be just a bit more but definitely competitive. Factor in the software savings and reduction in the number of servers required and the TCA and TCO will favor Power quickly. I do it all of the time and can back it up with hard data. You can run Power servers up to 90% utilization but rarely run x86 over 30%, maybe 35% tops.
With regard to @Brutalizer - Big claims of big servers, up to 96 TB of RAM. Who needs that? Who needs a server with 100's or 1000's of cores? The Oracle M6-32 has 1000 DIMMs to get 32 TB of memory. Tell us how this influences the MTBF of the server since the number of components is a major factor in the calculation. Next, you scoff at IBM for comparing to older servers. That is because they are talking to customers who are running older servers - consolidate those older servers onto a few or just 1 server that is inherently reliable - nothing more than a IBM mainframe followed by a IBM Power servers. Oracles M6-32 and M5-32 are just cables T5 servers scaled back from 16 to 12 cores. They have little RAS and built for marketing hype and to drive Oracle software licensing revenue. You say the Oracle M processor pricing is X and then try to paint picture that Power servers are more expensive for a 32 socket than a 8 socket - really. A v8 luxury car is more expensive than a 4 cyl econobox. The server price is moot when the real cost is the software you run on it. With Oracle EE + RAC at $70,500 + 22% annual maintenance per core it matters. On Power I only have to license the cores I need. If I need 2 cores for Oracle then I license 2 cores. On x86, the 15 core is 8. (15 x .5 = 7.5 rounds to 8). Oracle M series is also .5 so your 128 cores on SAP S&D to my 64 co Power7 at 1.0 puts us about equal. However, most customers don't run the servers with one workload. You will say your LDOMs is efficient but compared to Power Hypervisor it won't hold a candle to efficiently using the cores and threads - all of them in true multi-thread fashion. With Power8 coming out soon both Intel and Oracle will go back to smelling the fumes of Power servers. To customers out there. It isn't about being Ford or Chevy. This isn't college - don't root for your team even when they are no good. Your business has to not only survive but hopefully thrive. Do that on a platform that controls the largest cost which is software and Full Time Equivalents - that is Power servers.
Phil_Oracle - Monday, February 24, 2014 - linkWell I must say that this article is clearly Intel biased with a lot of misleading and downright wrong statements about Oracle and SPARC. Heres some accurate and substantiated counters:
"Sun/Oracle's server CPUs have been lagging severely in performance"
This is wrong, considering that since the SPARC T4 release, and now SPARC T5 and SPARC M6 announcements, Oracle has announced 20+ world record benchmarks across *all* of the public, audited benchmarks from TPC-C, TPC-H @ 1TB, 3TB, 10TB to SPECjEnterprise2010 and SPECjbb2013. Many of them are still valid today, almost a year later.
What I'd like to ask, is where are the 8-socket Xeon E7 v2 benchmarks to compare to SPARC? Theres only one today - SAP. And this doesn’t demonstrate database performance nor java application performance.
Theres also no 4-socket or 8-socket benchmarks on TPC-C, TPC-H, SPECjEnterprise2010.
Even with SPECjbb2013, theres just a 4-socket result, and if you compare performance/core, the SPARC T5-2 @ 114,492 max-jOPS (just 32-cores) has a 1.3x performance/core advantage over the NEC Express5800/A040b with 60 x Intel E7-4890 v2 2.8 GHz cores @ 177,753 max-jOPS.
"As usual, the published benchmarks are very vague and are only available for the top models "
As of today, there is not a single real world application/database benchmark that shows Xeon having superior throughput, response times or even price/performance comparing systems with same # of CPUs to SPARC T5. You can go here to see all the comparisons with full transparency. https://blogs.oracle.com/BestPerf/
"and the best performing systems come with astronomic price tags ($950,000 for two servers, some networking, and storage... really?)."
You do realize you are linking to Oracle Exadata which isn't a server but an Engineered system with many servers, storage and networking all built-in and based on XEON??
Why are you not linking to SPARC T5 server pricing which is here since that’s what you are trying to discredit? Heres the SPARC T5-2 pricing which is very aggressively priced to x86 & IBM Power7+ systems.
Or better yet, look at a public benchmark where full HW and SW pricing is disclosed?
A SPARC T5-4 is 2.4x faster than the 8-socket Xeon E7-4870 based HP DL980 G7 on TPC-H at 10TB.
The SPARC T5-4 server HW fully configured costs $268,853, HP DL 980 costs $268,431.
Basically same costs, SPARC T5 is 2.4x faster than Westmere-EX. Wheres Xeon E7 v2 to showcase its 2x faster??
Details of pricing and results are here.
On TPC-C OLTP benchmark, a SPARC T5-8 has a $/perf of .55USD/tpmC, versus fastest Oracle x2-8 of .89 USD/tpmC and IBM x3850 of .59USD/tpmC. SPARC T5-8 is 70% faster per CPU than Westmere-EX based Oracle x2-8. http://www.tpc.org/tpcc/results/tpcc_results.asp?o...
Haravikk - Tuesday, February 25, 2014 - linkI wouldn't mind a 60 core Xeon in the next version of Apple's Mac Pro ;)
Desert Dude - Thursday, April 3, 2014 - linkInteresting discussions. Just for clarification, there is an x86 server that goes beyond 8 sockets-bullion (Xeon E7 48xx up to 16sockets with near linear scale). Bull (legacy GE & Honeywell Mainframe) has leveraged technology used in its mainframe & HPC to build bullion...the world's FASTEST x86 server. bull.us/ bullion
