Dunnington: Why Intel Need 6 Cores to Beat AMD's 4

http://www.uberpulse.com/us/2008/03/dunnington_does_intel_need_6_cores_to_bea...

That's the question I've been pondering since yesterday's Intel briefing. I think Intel is rushing out to market its 6 cores Dunnington in order to stay competitive, now that AMD is finally shipping its quad-core server chip, Barcelona, delayed at least 6 months because of a bug. Thanks to its Direct Connect architecture, Barcelona would outperform Intel's fastest Xeon in large systems i.e. 4 or more CPUs per machine.

That's why Intel is positioning Dunnington for the 4+ sockets server market what the chip maker refers to EX i.e. expandable scalable/multiprocessor. Dunnington is based on dual core Penryn chips that are glued together. It still lacks the QuickPath Interconnect and the on-board memory controller of Nehalem. But Dunnington sounds like a great quick and cheap (because it reuses the Penryn building blocks) stop-gap solution. And contrary to Pat Gelsinger's opinion, I think Intel realise that they
might loose more market share in the high-end server space because of the continous latency of its Core architecture and "poof"... came out with a 6 core! "When we were defining Dunnington... we were trying to build a cost envelope for the EX server space... So we said we could do several ways. We could be a 4 core part with a really big cache. We could build an 8 core part and have a smaller cache. We basically ran a detail set of workload caracterisation to try to cover a range of performance requirements inside of a certain cost envelope. 6 cores with 16 MB of cache ended up being the sweetspot [for the EX market]", said Gelsinger.

Luckily, intel robs you practically.

Im sick of all this Intel i7 hype. Heres some actual factual proof why intel i7 is not designed for gaming but designed for servers.

Intel i7+large L3 cache+extremely small L2 cache= not very good gaming performance.

Fact:games Utilize large L2 cache, thats why current dual core and quads are good.

Intelligent comments please.

maybe vice-versa noobs?

well if intel needs 6 cores to beat amds 4 core kinda cool seing as now amd have 6 core processor so looks like intel needs 8 cores rofl

I'm with you on this one Jake, Eagle has no argument and is just making pointless statements...!

[kalimul]

Bitch you trippin'" as a wise man once said.

AMD can race ! in 2011 AMD get the 32nm tecnology !.

Stop trying circular arguments because you can't support your original claim. Intel are still winning, AMD have shown fantastic price/performance ratio and at certain points the Phenom II matches Intel Quads, but rarely gets above it.

If you said "I like AMD because they offer a great solution for the price", I would have agreed. But saying "AMD are winning the battle against Intel", you're just wrong.

umm ok i know your trying to act smart but unless you make/program computers i dont want to hear it

[LessthanJake14]

Look, benchmarks don't lie. The AMD's are CONSTANTLY being obliterated by Intels. Stop thinking that the underdog is really superior to Intel, because it just isn't.

No AMD is proper when it comes to big workstations - say for scoring digital music using hundreds of samples per second, or professional 3D modeling and rendering.
